-<p>Im Open-Source-Bereich ist es üblich, große Systeme in kleine Projekte aufzuteilen, die jeweils klein genug sind, dass eine endliche Menge an Entwicklern ausreicht, um sie weiterzuentwickeln. Beispielsweise ist ein CD-Brennprogramm aus einem Kommandozeilentool zusammengesetzt, das die CDs brennt und eine graphische Benutzerumgebung, die dieses Tool bedient. Ein Vorteil dieses Ansatzes ist es, daß dasselbe Kommandozeilenprogramm von vielen Stellen aus genutzt werden: Das Brennprogramm, ein “Sende an die CD”-Knopf und beispielsweise ein Backup-Tool. Ein weiterer Vorteil ist es, dass auf diese Weise für eine Funktionalität mehrere Benutzerinterfaces angeboten werden können.</p>

+<h2 id="maxima-und-wxmaxima"><span class="header-section-number">2.1</span> <em>Maxima</em> und wxMaxima</h2>
+<p>In the open-source domain, big systems are normally split into smaller projects that are easier to handle for small groups of developers. For example a CD burner program will consist of a command-line tool that actually burns the CD and a graphical user interface that allows users to implement it without having to learn about all the command line switches and in fact without using the command line at all. One advantage of this approach is that the developing work that was invested into the command-line program can be shared by many programs: The same CD-burner command-line program can be used as a âsend-to-CDâ-plug-in for a file manager application, for the âburn to CDâ function of a music player and as the CD writer for a DVD backup tool. Another advantage is that splitting one big task into smaller parts allows the developers to provide several user interfaces for the same program.</p>
 <p>Ein Computer-Algebrasystem (CAS) wie <em>Maxima</em> ist hervorragend für diesen Ansatz geeignet: Es kann die Logik hinter einem Taschenrechner liefern, der mit beliebig langen Zahlen hantieren kann, Formeln für ein größeres System, z.B. <a href="https://www.sagemath.org/">Sage</a> umstellen. Alternativ kann es direkt verwendet werden. Dies kann von der Kommandozeile aus geschehen, oder von wxMaxima aus, das eine komfortablere Bedienung unterstützt.</p>

 <p>Maxima ist ein komplettes Computer-Algebrasystem (CAS): Ein Programm, das die Formel, nicht nur die Zahl sucht, die ein mathematisches Problem löst. Auch wenn es darauf spezialisiert ist, mit Buchstaben zu rechnen, bietet es auch eine Menge an Funktionen, die Probleme lösen, für die nur numerische Lösungen existieren.</p>

-<p><em>wxMaxima</em> ist ein graphisches Benutzer-Interface, das die komplette Funktionalität und Flexibilität von Maxima zu nutzen erlaubt. Zudem bietet es viele Funktionalitäten an, die die Verwendung von <em>Maxima</em> einfacher gestalten. Beispielsweise kann es den Inhalt eines Arbeitsblattes, einer Zelle des Arbeitsblatts oder einen Teil einer Formel nach LaTeX, MathML oder in eine RTF-Formel für eine Textverarbeitung konvertieren. Dokumentation für wxMaxima kann <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">im Internet</a> gefunden werden, oder über das Hilfemenü.</p>
+<p>Extensive documentation for <em>Maxima</em> is <a href="https://maxima.sourceforge.io/documentation.html">available in the internet</a>. Part of this documentation is also available in wxMaximaâs help menu.

+<p><em>WxMaxima</em> is a graphical user interface that provides the full functionality and flexibility of <em>Maxima</em>. WxMaxima offers users a graphical display and many features that make working with <em>Maxima</em> easier. For example <em>wxMaxima</em> allows one to export any cellâs contents (or, if that is needed, any part of a formula, as well) as text, as LaTeX or as MathML specification at a simple right-click. Indeed, an entire workbook can be exported, either as a HTML file or as a LaTeX file. Documentation for <em>wxMaxima</em>, including workbooks to illustrate aspects of its use, is online at the <em>wxMaxima</em> <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">help site</a>, as well as via the help menu.</p>

-<p>wxMaxima ist größtenteils selbsterklärend. <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">Diese Internetseite</a> bietet einige Beispiele an, wovon das “10-Minuten-Tutorial” besonders zu empfehlen ist. Dieses Handbuch beschreibt einige zusätzliche Aspekte von wxMaxima.</p>

-<p>Eine der Sachen, die neue Benutzer oft verwirrt, ist, dass das Arbeitsblatt von wxMaxima in Zellen aufgeteilt ist, die nur auf Befehl vom Benutzer an <em>Maxima</em> gesendet werden. Dieser Ansatz ist jedoch für die Fehlersuche praktisch. Auch hat der gegenüber der Alternative, nach jeder Änderung alle Zellen im das Arbeitsblatt neu auszuwerten, oft viel Zeit.</p>
+<h2 id="grundlagen-zum-arbeitsblatt"><span class="header-section-number">2.2</span> Grundlagen zum Arbeitsblatt</h2>
+<p>Much of <em>wxMaxima</em> is self-explaining, but some details require attention. <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">This site</a> contains a number of workbooks that address various aspects of <em>wxMaxima</em>. Working through some of these (particularly the “10 minute <em>(wx)Maxima</em> tutorial”) will increase oneâs familiarity with both the content of <em>Maxima</em> and the use of <em>wxMaxima</em> to interact with <em>Maxima</em>. This manual concentrates on describing aspects of <em>wxMaxima</em> that are not likely to be self-evident and that might not be covered in the online material.</p>
+<h3 id="der-arbeitsblatt-ansatz"><span class="header-section-number">2.2.1</span> Der Arbeitsblatt-Ansatz</h3>
+<p>One of the very few things that are not standard in <em>wxMaxima</em> is that it organizes the data for <em>Maxima</em> into cells that are evaluated (which means: sent to <em>Maxima</em>) only when the user requests this. When a cell is evaluated, all commands in that cell, and only that cell, are evaluated as a batch. (The preceding statement is not quite accurate: One can select a set of adjacent cells and evaluate them together. Also, one can instruct <em>Maxima</em> to evaluate all cells in a workbook in one pass.) _WxMaxima_âs approach to submitting commands for execution might feel unfamiliar at the first sight. It does, however, drastically ease work with big documents (where the user does not want every change to automatically trigger a full re-evaluation of the whole document). Also, this approach is very handy for debugging.</p>
 <p>Wenn Text in <em>wxMaxima</em> eingegeben wird, erzeugt er automatisch eine neue Zelle des Arbeitsblattes. Wenn dies eine Code-Zelle ist, kann ihr Inhalt an <em>Maxima</em> gesendet werden und das Resultat dieser Aktion wird unter der Zelle angezeigt, wie unten abgebildet.</p>
 <figure>
 <img src="./InputCell.png" alt="Eingabe/Ausgabe Zelle" id="img_InputCell" /><figcaption>Eingabe/Ausgabe Zelle</figcaption>
 </figure>
-<p>Wird eine Code-Zelle ausgewertet, weist ihr <em>Maxima</em> eine Marke zu (standardmäßig ist diese in roter Schrift gehalten und beginnt mit einem <code>%i</code>), über das sie später wieder referenziert werden kann. Für die Ausgabe wird eine Marke generiert, die standardmäßig mit <code>%o</code> beginnt und nicht angezeigt wird, außer der Benutzer hat der Formel einen sprechenden Namen gegeben, der stattdessen angezeigt werden kann.</p>
-<p>Außer Code-Zellen kennt wxMaxima auch Testzellen und solche mit Bildern oder Überschriften. Jede Zelle hat ihren eigenen Speicher für das Rückgängigmachen von Aktionen, was sich oft als hilfreich erwiesen hat. Zudem besitzt, wie in fast allen Applikationen, das Arbeitsblatt einen eigenen Speicher für die Rückgängigmachen-Funktion.</p>
-<p>Die nun folgende Abbildung zeigt verschiedene Zelltypen (Titelzellen, Untertitelzellen, Textzellen, Eingabe/Ausgabezellen und eine Grafikzelle).</p>
+<p>On evaluation of an input cellâs contents the input cell <em>Maxima</em> assigns a label to the input (by default shown in red and recognizable by the <code>%i</code>) by which it can be referenced later in the <em>wxMaxima</em> session. The output that <em>Maxima</em> generates also gets a label that begins with <code>%o</code> and by default is hidden, except if the user assigns the output a name. In this case by default the user-defined label is displayed. The <code>%o</code>-style label <em>Maxima</em> auto-generates will also be accessible, though.</p>

-<li>Image cells.</li>

 </ul>
 <p>Wenn Text eingegeben ist, erzeugt <em>wxMaxima</em> normalerweise gleich eine Code-Zelle. Andere Zelltypen können über das “Zellen”-Menü, die dort dokumentierten Tastenkombinationen oder über die Werkzeugleiste erzeugt werden. Wenn eine nicht-mathematische Zelle (Überschrift, Text, etc.) erzeugt wurde, wird alles was eingetippt wird, als Text interpretiert.</p>
-<p>Ein Kommentar (wie in der Programmiersprache C) kann als Teil einer Mathematik-Eingabezelle eingegeben werden: <code>/* Dieser Kommentar wird von Maxima ignoriert */</code>.</p>

 <p>Wenn in einer Textverarbeitung versucht wird, einen Satz auszuwählen, wird diese versuchen, Beginn und Ende der Auswahl so zu verschieben, dass ganze Wörter ausgewählt sind. <em>wxMaxima</em> wird aus diesem Grund, wenn mehr als eine Zelle ausgewählt wird, die Auswahl auf ganze Zellen ausdehnen.</p>
-<p>Was ungewöhnlich erscheinen kann ist, dass <em>wxMaxima</em> alternativ einen vertikalen oder einen horizontalen Cursor darstellen kann:</p>
+<p>What isnât standard is that <em>wxMaxima</em> provides drag-and-drop flexibility by defining two types of cursors. <em>WxMaxima</em> will switch between them automatically when needed:</p>
 <ul>
-<li>Der Cursor wird vertikal dargestellt wird, wenn er zwischen zwei Zellen zu liegen kommt.</li>
-<li>Innerhalb einer Zelle wird der Cursor vertikal dargestellt.</li>
+<li>The cursor is drawn horizontally if it is moved in the space between two cells or by clicking there. - A vertical cursor that works inside a cell. This cursor is activated by moving the cursor inside a cell using the mouse pointer or the cursor keys and works much like the cursor in a text editor.</li>
 </ul>
-<p>When you start wxMaxima, you will only see the blinking horizontal cursor. If you start typing, a math cell will be automatically created and the cursor will change to a regular vertical one (you will see a right arrow as “prompt”, after the Math cell is evaluated (<kbd>CTRL+ENTER</kbd>), you will see the labels, e.g. <code>(%i1)</code>, <code>(%o1)</code>).</p>

 <p>Das Arbeitsblatt kann auf verschiedene Weisen gespeichert werden:</p>
-<h3 id="mac"><span class="header-section-number">1.3.1</span> .mac</h3>
-<p>.mac-Dateien sind Textdateien mit <em>Maxima</em>-Befehlen. Sie können über Maxima’s <code>batch()</code> oder <code>load()</code>-Befehl oder in wxMaxima über “Datei/Batch File laden” gelesen werden.</p>
-<p>One Example is shown below. <code>Quadratic.mac</code> defines a function and afterwards generates a plot with <code>wxdraw2d()</code>. Afterwards the contents of the file <code>Quadratic.mac</code> are printed and new defined function <code>f()</code> is evaluated.</p>
+<h3 id="mac"><span class="header-section-number">2.3.1</span> .mac</h3>
+<p><code>.mac</code> files are ordinary text files that contain <em>Maxima</em> commands. They can be read using _Maxima_âs <code>batch()</code> or <code>load()</code> command or _wxMaxima_âs File/Batch File menu entry.</p>
+<p>One example is shown below. <code>Quadratic.mac</code> defines a function and afterward generates a plot with <code>wxdraw2d()</code>. Afterward the contents of the file <code>Quadratic.mac</code> are printed and newly defined function <code>f()</code> is evaluated.</p>

+<img src="./BatchImage.png" alt="Laden einer Datei mit batch()" id="img_BatchImage" /><figcaption>Laden einer Datei mit <code>batch()</code></figcaption>
 </figure>
-<p>Achtung: Obwohl die Datei <code>Quadratic.mac</code> eine übliche Maxima-extension hat (<code>.mac</code>), kann sie nur durch wxMaxima verarbeitet werden, der Befehl <code>wxdraw2d()</code> ist eine wxMaxima-Erweiterung für <em>Maxima</em>.</p>
-<p><code>.mac</code>-Dateien eignen sich dafür, eine Bibliothek von Maxima-Befehlen aufzubauen. Ausreichend Information über die Struktur eines <em>wxMaxima</em>-Arbeitsblatts, dass sie es erlauben, dieses wieder zu rekonstruieren, enthalten sie aber nicht.</p>
-<h3 id="wxm"><span class="header-section-number">1.3.2</span> .wxm</h3>
-<p>.wxm-Dateien sollten das Arbeitsblatt außer <em>Maxima</em>’s Ausgabe enthalten. <em>Maxima</em> &gt;5.38 kann .wxm-Dateien über den <code>load()</code>-Befehl lesen. Das .wxm-Format ist allerdings oft weniger kompatibel mit älteren Versionen von <em>wxMaxima</em>, als das .wxmx-Format.</p>
-<h3 id="wxmx"><span class="header-section-number">1.3.3</span> .wxmx</h3>
+<p>Attention: Although the file <code>Quadratic.mac</code> has a usual <em>Maxima</em> extension (<code>.mac</code>), it can only be read by <em>wxMaxima</em>, since the command <code>wxdraw2d()</code> is a wxMaxima-extension to <em>Maxima</em>. (Command line) Maxima will ignore the unknown command <code>wxdraw2d()</code> and print it as output again.</p>
+<p>You can be use <code>.mac</code> files for writing your own library of macros. But since they donât contain enough structural information they cannot be read back as a <em>wxMaxima</em> session.</p>
+<h3 id="wxm"><span class="header-section-number">2.3.2</span> .wxm</h3>
+<p><code>.wxm</code> files contain the worksheet except for _Maxima_âs output. On Maxima versions &gt;5.38 they can be read using _Maxima_âs <code>load()</code> function just as .mac files can be. With this plain-text format, it sometimes is unavoidable that worksheets that use new features are not downwards-compatible with older versions of <em>wxMaxima</em>.</p>
+<h4 id="dateiformat-von-wxm-dateien"><span class="header-section-number">2.3.2.1</span> Dateiformat von wxm-Dateien</h4>
+<p>This is just a plain text file (you can open it with a text editor), containing the cell contents as some special Maxima comments.</p>
+<p>It starts with the following comment:</p>
+<p><code>/* [wxMaxima batch file version 1] [ DO NOT EDIT BY HAND! ]*/ /* [ Created with wxMaxima version 24.02.2_DevelopmentSnapshot ] */</code></p>
+<p>And then the cells follow, encoded as Maxima comments, e.g. a section cell:</p>
+<pre><code>/* [wxMaxima: section start ]
+Title of the section
+   [wxMaxima: section end   ] */</code></pre>
+<p>or (in a Math cell the input is of course <em>not</em> commented out (the output is not saved in a <code>wxm</code> file)):</p>
+<pre><code>/* [wxMaxima: input   start ] */
+f(x):=x^2+1$
+f(2);
+/* [wxMaxima: input   end   ] */</code></pre>
+<p>Images are <a href="https://en.wikipedia.org/wiki/Base64">Base64 encoded</a> with the image type as first line):</p>
+<pre><code>/* [wxMaxima: image   start ]
+jpg
+[very chaotic looking character sequence]
+   [wxMaxima: image   end   ] */</code></pre>
+<p>A page break is just one line containing:</p>
+<pre><code>/* [wxMaxima: page break    ] */</code></pre>
+<p>And folded cells marked by:</p>
+<pre><code>/* [wxMaxima: fold    start ] */

+<h4 id="file-format-of-wxmx-files"><span class="header-section-number">2.3.3.1</span> File format of wxmx files</h4>
+<p>A <code>wxmx</code>-file seems to be a binary format, but one can handle it with tools, which are included in your OS. It is a zip file, one can decompress it with <code>unzip</code> (maybe rename it before, so that is recognized by the unzip program of your OS). We do not use the compression function, just the possibility to merge several files into one file - images are already compressed and the rest is simple text (probably much smaller, than huge images, which are included).</p>
+<p>It does contain the following files:</p>
+<ul>
+<li><code>mimetype</code>: this file does contain the mimetype of wxMaxima files: <code>text/x-wxmathml</code> - <code>format.txt</code>: a short description about wxMaxima and the wxmx file format - Images (e.g. png, jpeg): inline plots which were produced in the wxMaxima session and included images. - <code>content.xml</code>: a XML document, which contains the various cells of your document in XML format.</li>
+</ul>
+<p>So, if something goes wrong, you can unzip a wxMaxima document (maybe rename it before to a <code>zip</code>-file), maybe make changes in the <code>content.xml</code> file with a text editor, or replace an broken image, zip the files again, probably rename the <code>zip</code> to a <code>wxmx</code>-file - and you get another modified <code>wxmx</code>-file.</p>

+<li><code>with_slider</code> und - <code>wxanimate</code>.</li>

 <p>Die Standard-Bildwiederholrate für Animationen kann im Konfigurations-Dialog von <em>wxMaxima</em> eingestellt werden. Um die Geschwindigkeit einer einzelnen Animation zu ändern, kann die Variable <code>wxanimate_framerate</code> geändert werden:</p>

-<p><em>Maxima</em> und wxMaxima kommunizieren über ein lokales Netzwerk miteinander.

+<p>Since <em>Maxima</em> (the program that does the actual mathematics) and <em>wxMaxima</em> (providing the easy-to-use user interface) are separate programs that communicate by the means of a local network connection. Therefore the most probable cause is that this connection is somehow not working. For example, a firewall could be set up in a way that it doesnât just prevent unauthorized connections from the internet (and perhaps intercept some connections to the internet, too), but also blocks inter-process-communication inside the same computer. Note that since <em>Maxima</em> is being run by a Lisp processor the process communication that is blocked does not necessarily have to be named “maxima”. Common names of the program that opens the network connection would be sbcl, gcl, ccl, lisp.exe, or similar names.</p>
+<p>On Unix computers another possible reason would be that the loopback network that provides network connections between two programs in the same computer isnât properly configured.</p>

+<p>This means that <em>wxMaxima</em> could not read the file <em>Maxima</em> that was supposed to instruct <em>Gnuplot</em> to create.</p>
 <p>Mögliche Gründe für diesen Fehler sind:</p>
 <ul>
-<li><code>implicit_plot</code> wurde verwendet, ohne vorher via <code>load()</code> geladen zu werden.</li>
-<li><em>Maxima</em> hat versucht, <em>Gnuplot</em> zu etwas zu bewegen, was die installierte Version von <em>Gnuplot</em> nicht versteht. In diesem Fall stehen die betreffenden Befehle in dem Verzeichnis, auf das <code>maxima_userdir</code> zeigt in einer Datei mit der Endung <code>.gnuplot</code>. Der Inhalt dieser Datei ist oft hilfreich, um den Fehler zu suchen.</li>
-<li>Gnuplot wurde über <em>wxMaxima</em>’s Konfigurationsdialog instruiert, pngcairo zu verwenden, unterstützt diese Ausgabefunktionen aber nicht. Dies ist auf dem Mac ein typisches Problem.</li>
-<li>Gnuplot hat keine gültige <code>.png</code>-Datei ausgegeben.</li>
+<li>The plotting command is part of a third-party package like <code>implicit_plot</code> but this package was not loaded by _Maxima_âs <code>load()</code> command before trying to plot. - <em>Maxima</em> tried to do something the currently installed version of <em>Gnuplot</em> isnât able to understand. In this case, a file ending in <code>.gnuplot</code> located in the directory, which _Maxima_âs variable <code>maxima_userdir</code> is pointing, contains the instructions from <em>Maxima</em> to <em>Gnuplot</em>. Most of the time, this fileâs contents therefore are helpful when debugging the problem. - Gnuplot was instructed to use the pngCairo library that provides antialiasing and additional line styles, but it was not compiled to support this possibility. Solution: Uncheck the “Use the Cairo terminal for the plot” checkbox in the configuration dialog and donât set <code>wxplot_pngcairo</code> to true from <em>Maxima</em>. - Gnuplot didnât output a valid <code>.png</code> file.</li>
 </ul>

-<h2 id="sbcl-beschwert-sich-über-einen-mangel-an-speicher"><span class="header-section-number">3.9</span> SBCL beschwert sich über einen Mangel an Speicher</h2>
-<p>Der Lisp Compiler SBCL reserviert gleich beim Hochfahren allen Speicher, den es im Betrieb nutzen will. Wird mehr Speicher benötigt, muss ihm über den Kommandozeilenparameter <code>--dynamic-space-size</code> gesagt werden, wie viel Speicher benötigt wird. SBCL kann nur in etwa die Hälfte des freien Speichers des Systems verwenden. Auf 32-Bit-Rechnern ist dies meist unter 999 Megabytes. Auf 64-Bit-Systemen können mehr als 1280 MB verwendet werden, was notwendig ist um das Lapack-Paket zu compilieren.</p>
-<p>Kommandozeilenparameter für <em>Maxima</em> (und daher für SBCL) können in <em>wxMaxima</em>’s Konfigurationsdialog eingegeben werden.</p>

+<p>One possible reason is that <em>Maxima</em> cannot be found in the location that is set in the âMaximaâ tab of _wxMaxima_âs configuration dialog and therefore wonât run at all. Setting the path to a working <em>Maxima</em> binary should fix this problem.</p>
+<h2 id="maxima-hört-nicht-auf-zu-rechnen-und-reagiert-nicht-auf-eingaben"><span class="header-section-number">5.8</span> Maxima hört nicht auf zu rechnen und reagiert nicht auf Eingaben</h2>
+<p>It is theoretically possible that <em>wxMaxima</em> doesnât realize that <em>Maxima</em> has finished calculating and therefore never gets informed it can send new data to <em>Maxima</em>. If this is the case âTrigger evaluationâ might resynchronize the two programs.</p>

+<p>Speicher</p>
+<p>The Lisp compiler SBCL by default comes with a memory limit that allows it to run even on low-end computers. When compiling a big software package like Lapack or dealing with extremely big lists of equations this limit might be too low. In order to extend the limits, SBCL can be provided with the command line parameter <code>--dynamic-space-size</code> that tells SBCL how many megabytes it should reserve. A 32bit Windows-SBCL can reserve up to 999 Megabytes. A 64-bit SBCL version running on Windows can be instructed to use more than the about 1280 Megabytes compiling Lapack needs.</p>
+<p>One way to provide <em>Maxima</em> (and thus SBCL) with command line parameters is the “Additional parameters for Maxima” field of _wxMaxima_âs configuration dialogue.</p>

+<p>Üblicherweise werden Programme mit einer graphischen Oberfläche einfach mit einem Mausklick auf ein Desktop-Icon oder einen Desktop-Menüeintrag gestartet. WxMaxima - falls es von der Kommandozeile aus gestartet wird - bietet doch einige Kommandozeilen-Optionen.</p>
 <ul>
 <li><code>-v</code> oder <code>--version</code>: Gibt die Versionsnummer aus</li>
 <li><code>-h</code> oder <code>--help</code>: Gibt einen kurzen Hilfetext aus</li>
 <li><code>-o</code> oder <code>--open=&lt;str&gt;</code>: Öffnet den Dateinamen, der als Argument dieser Kommandozeilenoption angegeben wurde.</li>
 <li><code>-e</code> oder <code>--eval</code>: Evaluiere die Datei nach dem Öffnen.</li>
-<li><code>-b</code> oder <code>--batch</code>: Nach dem Öffnen werden alle Code-Zellen der Datei(en) evaluiert und die Datei danach geschlossen. Dies ist beispielsweise praktisch, wenn <em>Maxima</em> Dateien generiert. Wenn Maxima Fehler detektiert, wird dieser Vorgang abgebrochen, eventuelle Fragen an den User (Mathematik ist an einigen Stellen ein interaktiver Prozess) werden wie üblich an den User weitergereicht.</li>
-<li><code>--logtostderr</code>: Gebe alle all Debug-Nachrichten auch auf der Standardfehlerausgabe (stderr) aus.</li>
-<li><code>--pipe</code>: Gebe die Nachrichten von Maxima auch auf die Konsole aus.</li>
-<li><code>--exit-on-error</code>: Schließe wxMaxima, wenn Maxima einen Fehler detektiert.</li>
-<li><code>-f</code> oder <code>--ini=&lt;str&gt;</code>: Speichere die Konfiguration in der Datei <code>&lt;str&gt;</code></li>
-<li><code>-u</code>, <code>--use-version=&lt;str&gt;</code>: Verwende Maxima-Version <code>&lt;str&gt;</code></li>
-<li><code>-l</code>, <code>--lisp=&lt;str&gt;</code>: Verwende ein Maxima, das mit dem Lisp Compiler <code>&lt;str&gt;</code> compiliert wurde.</li>
-<li><code>-X</code>, <code>--extra-args=&lt;str&gt;</code>: Erlaubt, Maxima zusätzliche Argumente mitzugeben</li>
-<li><code>-m</code> oder <code>--maxima=&lt;str&gt;</code>: Sagt, wo die ausführbare Datei von <em>maxima</em> liegt.</li>
-<li><code>--enableipc</code>: Lässt Maxima wxMaxima über Interprozesskommunikation ansteuern. Diese Option vorsichtig verwenden.</li>
+<li><code>-b</code> or <code>--batch</code>: If the command-line opens a file all cells in this file are evaluated and the file is saved afterward. This is for example useful if the session described in the file makes <em>Maxima</em> generate output files. Batch-processing will be stopped if <em>wxMaxima</em> detects that <em>Maxima</em> has output an error and will pause if <em>Maxima</em> has a question: Mathematics is somewhat interactive by nature so a completely interaction-free batch processing cannot always be guaranteed.</li>
+<li><code>--logtostderr</code>: Log all “debug messages” sidebar messages to stderr, too.</li>
+<li><code>--pipe</code>: Pipe messages from Maxima to stdout.</li>
+<li><code>--exit-on-error</code>: Close the program on any maxima error.</li>
+<li><code>-f</code> or <code>--ini=&lt;str&gt;</code>: Use the init file that was given as an argument to this command-line switch</li>
+<li><code>-u</code>, <code>--use-version=&lt;str&gt;</code>: Use maxima version <code>&lt;str&gt;</code>.</li>
+<li><code>-l</code>, <code>--lisp=&lt;str&gt;</code>: Use a Maxima compiled with Lisp compiler <code>&lt;str&gt;</code>.</li>
+<li><code>-X</code>, <code>--extra-args=&lt;str&gt;</code>: Allows to specify extra Maxima arguments</li>
+<li><code>-m</code> or <code>--maxima=&lt;str&gt;</code>: allows specifying the location of the <em>maxima</em> binary</li>
+<li><code>--enableipc</code>: Lets Maxima control wxMaxima via interprocess communications. Use this option with care.</li>
+<li><code>--wxmathml-lisp=&lt;str&gt;</code>: Location of wxMathML.lisp (if not the built-in should be used, mainly for developers).</li>
 </ul>
 <p>Manche Betriebssysteme verwenden bei Kommandozeilenparametern einen Schrägstrich statt eines Minuszeichens.</p>

+<h1 id="über-das-programm-zu-wxmaxima-beitragen"><span class="header-section-number">8</span> Über das Programm, zu wxMaxima beitragen</h1>
+<p>wxMaxima is mainly developed using the programming language C++ using the <a href="https://www.wxwidgets.org">wxWidgets framework</a>, as build system we use <a href="https://www.cmake.org">CMake</a>, a small part is written in Lisp. You can contribute to wxMaxima, join the wxMaxima project at <a href="https://github.com/wxMaxima-developers/wxmaxima" class="uri">https://github.com/wxMaxima-developers/wxmaxima</a>, if you have knowledge of these programming languages and want to help and contribute to the open source project wxMaxima.</p>
+<p>But not only programmers are necessary! You can also contribute to wxMaxima, if you help to improve the documentation, find and report bugs (and maybe bugfixes), suggest new features, help to translate wxMaxima or the manual to your language (read the README.md in the <a href="https://github.com/wxMaxima-developers/wxmaxima/tree/main/locales">locale subdirectory</a> how wxMaxima and the manual can be translated).</p>
+<p>Oder Fragen von anderen Benutzern im Diskussionsforum beantworten.</p>
+<p>Der Quellcode von wxMaxima ist mit Doxygen <a href="https://wxmaxima-developers.github.io/wxmaxima/Doxygen-documentation/">hier</a> dokumentiert.</p>
+<p>Das Programm ist nahezu unabhängig, ausser einiger Systembibliotheken (und der wxWidgets-Bibliothek) sind keine externen Abhängigkeiten (z.B. externe Graphiken oder der Lisp-Teil (die <code>wxMathML.lisp</code>-Datei) notwendig, diese Dateien sind alle in wxMaxima eingebaut.</p>
+<p>Wenn Sie ein Entwickler sind und eine modifizierte <code>wxmathML.lisp</code>-Datei verwenden wollen, ohne alles neu zu compilieren, kann mit der Kommandozeilenoption <code>--wxmathml-lisp=&lt;str&gt;</code> eine andere Lisp-Datei verwendet werden, nicht die eincompilierte Variante.</p>

-<p>En el dominio de código abierto, los sistemas grandes están divididos normalmente en proyectos más pequeños que son más fáciles para manipular en grupos pequeños de desarrolladores. Por ejemplo un programa para el quemado del DVD consistirá de una herramienta de línea de instrucciones que actualmente quema el CD un interfaz gráfico de usuario que permite a los usuarios implementarlo sin tener que aprenderse todas las opciones de línea de instrucciones como complemento “enviar-a-CD”para una aplicación de gestión de ficheros, para la función «quemar a CD» de un reproductor de música y como el grabador de CD para una herramienta de respaldo DVD. Otra ventaja es que dividiendo una tarea grande en partes más pequeñas permite a los desarrolladores proporcionar varios interfaces de usuarios para el mismo programa.</p>

+<p>In the open-source domain, big systems are normally split into smaller projects that are easier to handle for small groups of developers. For example a CD burner program will consist of a command-line tool that actually burns the CD and a graphical user interface that allows users to implement it without having to learn about all the command line switches and in fact without using the command line at all. One advantage of this approach is that the developing work that was invested into the command-line program can be shared by many programs: The same CD-burner command-line program can be used as a âsend-to-CDâ-plug-in for a file manager application, for the âburn to CDâ function of a music player and as the CD writer for a DVD backup tool. Another advantage is that splitting one big task into smaller parts allows the developers to provide several user interfaces for the same program.</p>
 <p>Un sistema de computación algebraico (CAS) como <em>Maxima</em> encaja dentro de este marco referencial. Un CAS puede proporcionar la lógica detrás de la aplicación de precisión de cálculo arbitrario o puede hacer transformaciones automáticas de fórmulas en el segundo plano de un sistema más grande (p.e., [Sage] (https://www.sagemath.org/)). Alternativamente, puede ser utilizado directamente como un sistema independiente. <em>Maxima</em> pude ser accedido vía una línea de instrucción. A menudo, sin embargo, un interfaz como <em>wxMaxima</em> proporciona una manera más eficiente para acceder al software, especialmente para los recién llegados.</p>

 <p><em>Maxima</em> es un sistema algebraico computador completo (CAS) de características. Un CAS es un programa que puede resolver problemas matemáticos reconociendo fórmulas y encontrando una fórmula que resuelva el problema como difícil a ajustar la salida del valor numérico del resultado. En otras palabras, <em>Maxima</em> pude servir como una calculadora que proporciona representaciones numéricas de variables, y además puede proporcionar soluciones analíticas. Más aún, ofrece un rango de métodos numéricos para ecuaciones o sistemas de ecuaciones que no pueden ser analíticamente resueltos.</p>

-<p><em>wxMaxima</em> es un interfaz del usuario gráfico que proporciona la completa funcionalidad y flexibilidad de <em>Maxima</em>. wxMaxima proporciona a los usuarios una pantalla gráfica y varias características que hacen trabajar más fácilmente con <em>Maxima</em>. Por ejemplo <em>wxMaxima</em> permite uno exportar cualquier contenido de celdas (o, si eso es necesario, cualquier parte de una fórmula, también) como texto, como especificación LaTeX o MathML solo con una pulsación secundaria. Por cierto, un cuaderno completo , puede ser exportado, o bien como un fichero HTML o como un fichero LaTeX. La documentación para <em>wxMaxima</em>, incluyendo cuadernos para ilustrar aspectos de su uso, está por conexión al <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">sitio web</a> de <em>wxMaxima</em>, así como a través del menú de ayuda.</p>

+<p><em>WxMaxima</em> is a graphical user interface that provides the full functionality and flexibility of <em>Maxima</em>. WxMaxima offers users a graphical display and many features that make working with <em>Maxima</em> easier. For example <em>wxMaxima</em> allows one to export any cellâs contents (or, if that is needed, any part of a formula, as well) as text, as LaTeX or as MathML specification at a simple right-click. Indeed, an entire workbook can be exported, either as a HTML file or as a LaTeX file. Documentation for <em>wxMaxima</em>, including workbooks to illustrate aspects of its use, is online at the <em>wxMaxima</em> <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">help site</a>, as well as via the help menu.</p>

-<h2 id="cuaderno-básico"><span class="header-section-number">1.2</span> Cuaderno básico</h2>
-<p>Mucho de <em>wxMaxima</em> son auto-explicativos, pero algunos detalles requieren atención. <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">Este sitio</a> contiene un número de cuadernos que dirige varios aspectos de <em>wxMaxima</em>. Trabajar junto algunos de estos (particularmente el tutorial de «10 minutos <em>(wx)Maxima</em>») incrementará la familiaridad de uno con los ambos del contenido de <em>Maxima</em> y el uso de <em>wxMAxima</em> para interactuar con <em>maxima</em>. Este manual se concentra en describir aspectos de <em>wxMaxima</em> que no son como los evidentes y que tal vez no está cubierto dentro del material por línea.</p>
-<h3 id="la-aproximación-del-cuaderno"><span class="header-section-number">1.2.1</span> La aproximación del cuaderno</h3>
-<p>Una de las muy pocas cosas que no son normalizadas en <em>wxMaxima</em> es que se organiza los datos para <em>Maxima</em> dentro de celdas que son evaluadas (la cual indica: envía a <em>maxima</em>) solamente cuando solicita el usuario esto. Cuando una celda es evaluada, todas las instrucciones dentro de esa celda, y solamente esa celda, son evaluadas como un guión. (El enunciado precedente no es muy preciso: uno puede seleccionar un conjunto de celdas adyacentes y evaluarlas a la vez. Además , una pude instruir a <em>Maxima</em> que evalúe todas las celdas dentro de un cuaderno en una pasada). La aproximación de _wxMaxima para enviar instrucciones para ejecutar tal vez se siente poco familiar en el primer momento. Sin embargo, drásticamente trabaja fácilmente con documentos grandes (cuando el usuario no desea cada modificación para disparar automáticamente una re-evaluación completa del documento completo). Además, esta aproximación es muy útil para depurar.</p>
+<h2 id="cuaderno-básico"><span class="header-section-number">2.2</span> Cuaderno básico</h2>
+<p>Much of <em>wxMaxima</em> is self-explaining, but some details require attention. <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">This site</a> contains a number of workbooks that address various aspects of <em>wxMaxima</em>. Working through some of these (particularly the “10 minute <em>(wx)Maxima</em> tutorial”) will increase oneâs familiarity with both the content of <em>Maxima</em> and the use of <em>wxMaxima</em> to interact with <em>Maxima</em>. This manual concentrates on describing aspects of <em>wxMaxima</em> that are not likely to be self-evident and that might not be covered in the online material.</p>
+<h3 id="la-aproximación-del-cuaderno"><span class="header-section-number">2.2.1</span> La aproximación del cuaderno</h3>
+<p>One of the very few things that are not standard in <em>wxMaxima</em> is that it organizes the data for <em>Maxima</em> into cells that are evaluated (which means: sent to <em>Maxima</em>) only when the user requests this. When a cell is evaluated, all commands in that cell, and only that cell, are evaluated as a batch. (The preceding statement is not quite accurate: One can select a set of adjacent cells and evaluate them together. Also, one can instruct <em>Maxima</em> to evaluate all cells in a workbook in one pass.) _WxMaxima_âs approach to submitting commands for execution might feel unfamiliar at the first sight. It does, however, drastically ease work with big documents (where the user does not want every change to automatically trigger a full re-evaluation of the whole document). Also, this approach is very handy for debugging.</p>
 <p>Si el texto está tecleado en <em>wxMaxima</em> automáticamente crea una celda de hoja de trabajo nueva. El tipo de esta celda puede ser seleccionado en la barra de herramientas. Si se crea una celda de código, la celda puede ser enviada a <em>Maxima</em>, la cual causa que el resultado del cálculo es desplegado debajo del código. Una pareja de dichas instrucciones se muestra debajo.</p>
 <figure>
 <img src="./InputCell.png" alt="Celda de entrada/salida" id="img_InputCell" /><figcaption>Celda de entrada/salida</figcaption>
 </figure>
-<p>En la evaluación de los contenidos de celda de entrada la celda <em>Maxima</em> de entrada asigna una etiqueta a la entrada (por defecto muestra en rojo y reconocible por el «%i») por el cual puede ser referenciado posteriormente dentro de la sesión _wxMaxima:. La salida que genera <em>Maxima</em> genera además obtener una etiqueta que comience con «%o» y por defecto está oculta, excepto si el usuario asigna la salida un nombre. En este caso por defecto el etiquetado definido por el usuario está desplegado. EL estilo «%o» de etiquetado <em>Maxima</em> auto-genera además será accesible, sin embargo.</p>
-<p>Al lado de las celdas de entradas <em>wxMaxima</em> permite celdas de texto para documentación, celdas de imagen, celdas de título, celdas de capítulo y celdas de sección. Cada celda tiene su propio búfer para deshacer por lo que se depura a través de modificar los valores de varias celdas y después gradualmente es más fácil revertir las modificaciones no necesarias. Además el mismo cuaderno tiene un búfer global para deshacer que puede deshacer celdas editadas, agregar y borrar.</p>
+<p>On evaluation of an input cellâs contents the input cell <em>Maxima</em> assigns a label to the input (by default shown in red and recognizable by the <code>%i</code>) by which it can be referenced later in the <em>wxMaxima</em> session. The output that <em>Maxima</em> generates also gets a label that begins with <code>%o</code> and by default is hidden, except if the user assigns the output a name. In this case by default the user-defined label is displayed. The <code>%o</code>-style label <em>Maxima</em> auto-generates will also be accessible, though.</p>
+<p>Al lado de las celdas de entradas <em>wxMaxima</em> permite celdas de texto para documentación, celdas de imagen, celdas de título, celdas de capítulo y celdas de sección.

+<p>What isnât standard is that <em>wxMaxima</em> provides drag-and-drop flexibility by defining two types of cursors. <em>WxMaxima</em> will switch between them automatically when needed:</p>
 <ul>
-<li>El cursor es dibujado horizontalmente si es trasladado dentro del espacio entre dos celdas o pulsando allí.</li>
-<li>Un cursor vertical que funciona dentro de una celda. Este cursor está activado moviendo el cursor dentro de una celda utilizando el puntero del ratón o las teclas del cursor y funciona como el cursor en un editor de texto.</li>

+<p>Attention: Although the file <code>Quadratic.mac</code> has a usual <em>Maxima</em> extension (<code>.mac</code>), it can only be read by <em>wxMaxima</em>, since the command <code>wxdraw2d()</code> is a wxMaxima-extension to <em>Maxima</em>. (Command line) Maxima will ignore the unknown command <code>wxdraw2d()</code> and print it as output again.</p>
+<p>You can be use <code>.mac</code> files for writing your own library of macros. But since they donât contain enough structural information they cannot be read back as a <em>wxMaxima</em> session.</p>
+<h3 id="wxm"><span class="header-section-number">2.4.2</span> .wxm</h3>

On Maxima versions &gt;5.38 they can be read using _Maxima_âs <code>load()</code> function just as .mac files can be.

+<p>A <code>wxmx</code>-file seems to be a binary format, but one can handle it with tools, which are included in your OS. It is a zip file, one can decompress it with <code>unzip</code> (maybe rename it before, so that is recognized by the unzip program of your OS). We do not use the compression function, just the possibility to merge several files into one file - images are already compressed and the rest is simple text (probably much smaller, than huge images, which are included).</p>
+<p>It does contain the following files:</p>
+<ul>
+<li><code>mimetype</code>: this file does contain the mimetype of wxMaxima files: <code>text/x-wxmathml</code> - <code>format.txt</code>: a short description about wxMaxima and the wxmx file format - Images (e.g. png, jpeg): inline plots which were produced in the wxMaxima session and included images. - <code>content.xml</code>: a XML document, which contains the various cells of your document in XML format.</li>
+</ul>
+<p>So, if something goes wrong, you can unzip a wxMaxima document (maybe rename it before to a <code>zip</code>-file), maybe make changes in the <code>content.xml</code> file with a text editor, or replace an broken image, zip the files again, probably rename the <code>zip</code> to a <code>wxmx</code>-file - and you get another modified <code>wxmx</code>-file.</p>

-<p>La característica de ayuda del botón 2D es que permite configurar la escena como una animación en la cual una variable (por defecto es <em>t</em>) tiene un valor diferente dentro de cada marco: A menudo un movimiento de trama 2D permite una interpretación más fácil que el de datos dentro de uno sin movimiento 3D.</p>

+<p>Generates the skeleton of a <code>draw()</code> command that draws a 2D scene. This scene later has to be filled with commands that generate the sceneâs contents, for example by using the buttons in the rows below the “2D” button.</p>
+<p>La característica de ayuda del botón 2D es que permite configurar la escena como una animación en la cual una variable (por defecto es <em>t</em>) tiene un valor diferente dentro de cada marco: a menudo un movimiento de trama 2D permite una interpretación más fácil que el de datos dentro de uno sin movimiento 3D.</p>

-<p>Si el formato de fichero <code>.wxmx</code> está siendo utilizado empotrando dicheros dentro de un proyecto <em>wxMaxima</em> puede ser hecho como fácilmente como por arrastrar-y-soltar.

+<h3 id="modify-font-and-font-size-for-plots."><span class="header-section-number">3.4.6</span> Modify font and font size for plots.</h3>
+<p>Especially when you use a high resolution display, the default font size might be very small. For the <code>draw</code>-based commands, you can set the font / font size using options like <code>font=...</code>, <code>font_size=...</code>, e.g.:</p>

+<p>For the <code>plot</code>-commands (e.g. <code>wxplot2d</code>, <code>wxplot3d</code>) font sizes and fonts can be set using the <code>gnuplot_preamble</code> command, e.g.:</p>
+<div class="sourceCode" id="cb19"><pre class="sourceCode maxima"><code class="sourceCode maxima"><a class="sourceLine" id="cb19-1" title="1"><span class="cn">wxplot2d</span>(<span class="fu">sin</span>(<span class="cn">x</span>),[<span class="cn">x</span>,<span class="dv">1</span>,<span class="dv">10</span>],</a>

+<p>This sets the font for the numbers to Arial with size 30, the size for the xlabel and ylabel font to 20 (with the default font).</p>
+<p>Read the Maxima and Gnuplot documentation for further information. Note: Gnuplot seems to have issues with larger font sizes, see <a href="https://github.com/wxMaxima-developers/wxmaxima/issues/1966">wxMaxima issue 1966</a>.</p>

+<p>If the <code>.wxmx</code> file format is being used embedding files in a <em>wxMaxima</em> project can be done as easily as per drag-and-drop. But sometimes (for example if an imageâs contents might change later on in a session) it is better to tell the file to load the image on evaluation:</p>

 </ul>
-<p>Estos ficheros están dentro del directorio del usuario de Maxima (usualmente <code>maxima</code> en Windows, <code>.maxima</code> en otros sitios) dentro del directorio inicial del usuario / perfil. La ubicación puede ser encontrada fuera con la instrucción: <code>maxima_userdir;</code></p>
-<h2 id="variables-especiales-wx"><span class="header-section-number">2.6</span> Variables especiales wx…</h2>

+<p>These files are in the Maxima user directory (usually <code>%USERPROFILE%/maxima</code> in Windows, <code>$HOME/.maxima</code> otherwise). The location can be found out with the command: <code>maxima_userdir;</code></p>

 <ul>
-<li>‘wxsubscripts’ le dice a <em>Maxima</em> si debería convertir los nombres de variables que contengan un guión bajo (‘R_150’ o lo similar) en variables sub-guion. Vea ‘wxdeclare_subscript’ para detalles los cuales nombres de variables son convertidos automáticamente.</li>
-<li><code>wxfilename</code>: esta variable contiene el nombre del fichero actualmente abierto en <em>wxMaxima</em>.</li>
-<li><code>wxdirname</code>: This variable contains the name the directory, in which the file currently opened in <em>wxMaxima</em> is.</li>
-<li><code>wxplot_pngcairo</code> indica si <em>wxMaxima</em> intenta utilizar el terminal de pngcairo <em>gnuplot</em> que proporciona más estilos de línea y un mejor calidad gráfica sobre todo.</li>
-<li><code>wxplot_size</code> define la resolución de tramas empotradas.</li>
-<li><code>wxchangedir</code>: en la mayoría de los sistemas <em>wxMaxima</em> establece automáticamente el directorio de trabajo de <em>Maxima</em> al directorio del fichero actual. Esto permite la E/S del fichero (p.ej. a través de <code>read_matrix</code>) para trabajar sin especificar la ruta completa del fichero que tiene que ser leído o escrito. En Windows algunas veces esta característica causa mensajes de error y por lo tanto puede ser puesta a <code>false</code> desde el dialogo de configuración.</li>
-<li><code>wxanimate_framerate</code>: El número de marcos por segundo de las siguientes animaciones con las que tienen que ser representadas.</li>
-<li><code>wxanimate_autoplay</code>: Reproduce automáticamente animaciones predeterminadamente?</li>
-<li><code>wxmaximaversion</code>: Returns the version number of <em>wxMaxima</em>.</li>
-<li><code>wxwidgetsversion</code>: Returns the wxWidgets version <em>wxMaxima</em> is using.</li>
+<li><code>wxsubscripts</code> tells <em>Maxima</em> if it should convert variable names that contain an underscore (<code>R_150</code> or the like) into subscripted variables. See <code>wxdeclare_subscript</code> for details which variable names are automatically converted. - <code>wxfilename</code>: This variable contains the name of the file currently opened in <em>wxMaxima</em>. - <code>wxdirname</code>: This variable contains the name the directory, in which the file currently opened in <em>wxMaxima</em> is. - <code>wxplot_pngcairo</code> tells whether <em>wxMaxima</em> tries to use _Gnuplot_âs pngcairo terminal that provides more line styles and a better overall graphics quality. - <code>wxplot_size</code> defines the resolution of embedded plots. - <code>wxchangedir</code>: On most operating systems <em>wxMaxima</em> automatically sets _Maxima_âs working directory to the directory of the current file. This allows file I/O (e.g. by <code>read_matrix</code>) to work without specifying the whole path to the file that has to be read or written. On Windows this feature sometimes causes error messages and therefore can be set to <code>false</code> from the config dialogue. - <code>wxanimate_framerate</code>: The number of frames per second the following animations have to be played back with. - <code>wxanimate_autoplay</code>: Automatically play animations by default? - <code>wxmaximaversion</code>: Returns the version number of <em>wxMaxima</em>. - <code>wxwidgetsversion</code>: Returns the wxWidgets version <em>wxMaxima</em> is using.</li>

-<p>Dese <em>Maxima</em> (el programa que hace las matemáticas actuales) y <em>wxMaxima</em> (proporcionando el interfaz de usuario fácil-de-uso) con programas separados que se comunican por los medios de una conexión de red local. Por lo tanto la causa más probable es que esta conexión es algo que no funciona. Por ejemplo un cortafuegos pude establecer de una manara que no impida conexiones no autorizadas desde el Internet (y quizá interceptar algunas conexiones para Internet, también), pero también para bloques de comunicación de inter-procesos dentro del mismo computador. Nota que desde <em>Maxima</em> es siendo ejecutado por un procesador Lisp la comunicación de procesos que están bloqueados desde unos no necesariamente tienen que ser nombrados “maxima”. Los nombres comunes del programa que abre la conexión de red pudo ser sbcl, gcl, ccl, lisp.exe o nombres similares.</p>

-<p>If the zip signature at the end of the file is still intact after renaming a broken <code>.wxmx</code> file to <code>.zip</code> most operating systems will provide a way to extract any portion of information that is stored inside it.

If the zip signature isn’t intact that does not need to be the end of the world: If <em>wxMaxima</em> during saving detected that something went wrong there will be a <code>.wxmx~</code> file whose contents might help.</p>
-<p>E incluso si no hay un fichero: el fichero <code>.wxmx</code> es un formato de contenedor y la porción es almacenada sin comprimir. Es posible renombrar el fichero <code>.wxmx</code> a un fichero <code>.tct</code> y utilizar un editor de texto para recuperar la porción XML del contenido del fichero (se inicia con <code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;</code> y termina con <code>&lt;/wxMaximaDocument&gt;</code>.

+<p>Since <em>Maxima</em> (the program that does the actual mathematics) and <em>wxMaxima</em> (providing the easy-to-use user interface) are separate programs that communicate by the means of a local network connection. Therefore the most probable cause is that this connection is somehow not working. For example, a firewall could be set up in a way that it doesnât just prevent unauthorized connections from the internet (and perhaps intercept some connections to the internet, too), but also blocks inter-process-communication inside the same computer. Note that since <em>Maxima</em> is being run by a Lisp processor the process communication that is blocked does not necessarily have to be named “maxima”. Common names of the program that opens the network connection would be sbcl, gcl, ccl, lisp.exe, or similar names.</p>
+<p>On Unix computers another possible reason would be that the loopback network that provides network connections between two programs in the same computer isnât properly configured.</p>

+<p>mensaje de error</p>
+<p>Esto significa que <em>wxMaxima</em> no pudo leer el archivo <em>Maxima</em> que fue proporcionado a la instrucción <em>Gnuplot</em> para crear.</p>
 <p>Las posibles razones de este error son:</p>
 <ul>
-<li>La instrucción de tramado es parte de un paquete de tercera parte como ‘implicit_plot’ pero este paquete no fue cargado por la instrucción ‘load()’ de <em>Maxima</em> porque está intentando puntear.</li>
-<li><em>Maxima</em> intentó hacer algo que la versión actualmente instalada de <em>gnuplot</em> no es capaz de entender. En este caso, un fichero terminando en <code>.gnuplot</code> localizado en el directorio, el cual la variable <code>maxima_userdir</code> está apuntando, contiene las instrucciones desde <em>Maxima</em> para <em>gnuplot</em>. La mayoría del tiempo, estos contenidos del fichero contiene por lo tanto ayuda cuando se depura el problema.</li>
-<li>Gnuplot fue instruido para utilizar la biblioteca pngcairo que proporciona antialias y estilos de líneas adicionales, pero no fue compilado para admitir esta posibilidad. Solución: Desmarque la casilla «Utilizar el terminal cairo para tramas» dentro del diálogo de configuración y no establezca <code>wxplot_pngcairo</code> a cierto desde <em>Maxima</em>.</li>
-<li>Gnuplot no saca un fichero «.png» válido.</li>
+<li>The plotting command is part of a third-party package like <code>implicit_plot</code> but this package was not loaded by _Maxima_âs <code>load()</code> command before trying to plot. - <em>Maxima</em> tried to do something the currently installed version of <em>Gnuplot</em> isnât able to understand. In this case, a file ending in <code>.gnuplot</code> located in the directory, which _Maxima_âs variable <code>maxima_userdir</code> is pointing, contains the instructions from <em>Maxima</em> to <em>Gnuplot</em>. Most of the time, this fileâs contents therefore are helpful when debugging the problem. - Gnuplot was instructed to use the pngCairo library that provides antialiasing and additional line styles, but it was not compiled to support this possibility. Solution: Uncheck the “Use the Cairo terminal for the plot” checkbox in the configuration dialog and donât set <code>wxplot_pngcairo</code> to true from <em>Maxima</em>. - Gnuplot didnât output a valid <code>.png</code> file.</li>

 <ul>
-<li><em>wxMaxima</em> actualmente tiene dos características de deshacer: el búfer de deshacer global que está activo si ninguna celda está seleccionada y un deshacer por celda que está activo si el cursor está dentro de una celda.

-<li>Si todavía tiene una manera de encontrar cual etiqueta de <em>Maxima</em> ha asignado a la celda tan solo teclee dentro de la etiqueta de la celda y sus contenidos aparecerán.</li>
-<li>Si no: no se asuste. En el menú “Vista” hay una manera de ver un panel histórico que muestra todas las instrucciones de <em>Maxima</em> que han sido emitidas recientemente.</li>
-<li>Si nada más ayuda <em>Maxima</em> contiene una característica de reproducción:</li>
+<li><em>WxMaxima</em> actually has two undo features: The global undo buffer that is active if no cell is selected and a per-cell undo buffer that is active if the cursor is inside a cell. It is worth trying to use both undo options in order to see if an old value can still be accessed. - If you still have a way to find out what label <em>Maxima</em> has assigned to the cell just type in the cellâs label and its contents will reappear. - If you donât: Donât panic. In the âViewâ menu there is a way to show a history pane that shows all <em>Maxima</em> commands that have been issued recently. - If nothing else helps <em>Maxima</em> contains a replay feature:</li>

+<p>One possible reason is that <em>Maxima</em> cannot be found in the location that is set in the âMaximaâ tab of _wxMaxima_âs configuration dialog and therefore wonât run at all. Setting the path to a working <em>Maxima</em> binary should fix this problem.</p>

+<p>wxMaxima o línea de instrucción de Maxima?</p>
+<p>Si se utiliza wxMaxima, la variable <code>maxima_frontend</code> de Maxima está fijada a <code>wxmaxima</code>. La variable Maxima <code>maxima_frontend_version</code> contiene la versión de wxMaxima en este caso.</p>
+<p>Si no ningún frontend es utilizado (está utilizando Maxima en línea de instrucción), estas variables son falsas.</p>

-<h1 id="argumentos-de-línea-de-instrucción"><span class="header-section-number">5</span> Argumentos de línea de instrucción</h1>
-<p>Muchos sistemas operativos proporcionan menos formas complicadas de iniciar programas que la línea de instrucciones por lo que esta posibilidad es únicamente raramente utilizada. <em>wxMaxima</em> aún proporciona algunos indicadores por línea de instrucciones, de todas formas.</p>
+<h1 id="argumentos-de-línea-de-instrucción"><span class="header-section-number">7</span> Argumentos de línea de instrucción</h1>
+<p>Usualmente puede iniciar programas con un interfaz gráfico de usuario tan solo pulsando en un icono de escritorio o apunte de menú del escritorio. wxMaxima -si inició desde la línea de instrucción- aún proporciona algunos interruptores en línea de instrucción, sin embargo.</p>
 <ul>
 <li>‘-v’ o ‘–version’: extrae la información de la versión</li>
 <li>‘-h’ o ‘–help’: extrae un texto breve de ayuda</li>
-<li>‘-o’ o ‘–open=<cdn>’: abre el nombre del fichero dado como argumento a este interruptor de línea-transaccional</li>
-<li>‘-e’ o ‘–eval’: evalúa el fichero tras abrirlo.</li>
-<li>‘-b’ o ‘–batch’: si la línea de instrucción abre un fichero todas las celdas dentro de este fichero son evaluadas y el fichero es guardado después. Esto es para ejemplo útil si la sesión descrita dentro del fichero hace que <em>Maxima</em> genere ficheros de salida. Los procesamientos batch serán detenidos si <em>wxMaxima</em> detecta que <em>Maxima</em> tiene un error de salida y lo detendrá si <em>Maxima</em> tiene una cuestión: las matemáticas es algo interactivo por naturaliza por lo que un proceso de batch libre de interacción no puede ser completamente garantizado.</li>
-<li><code>--logtostderr</code>: Log all “debug messages” sidebar messages to stderr, too.</li>
-<li><code>--pipe</code>: Pipe messages from Maxima to stdout.</li>
-<li><code>--exit-on-error</code>: Close the program on any maxima error.</li>
-<li><code>-f</code> or <code>--ini=&lt;str&gt;</code>: Use the init file that was given as argument to this command-line switch</li>
-<li><code>-u</code>, <code>--use-version=&lt;str&gt;</code>: Use maxima version <code>&lt;str&gt;</code>.</li>
-<li><code>-l</code>, <code>--lisp=&lt;str&gt;</code>: Use a Maxima compiled with Lisp compiler <code>&lt;str&gt;</code>.</li>
-<li><code>-X</code>, <code>--extra-args=&lt;str&gt;</code>: Allows to specify extra Maxima arguments</li>
-<li><code>-m</code> or <code>--maxima=&lt;str&gt;</code>: allows to specify the location of the <em>maxima</em> binary</li>
-<li><code>--enableipc</code>: Lets Maxima control wxMaxima via interprocess communications. Use this option with care.</li>
+<li><code>-o</code> u <code>--open=&lt;cad&gt;</code>: abre el nombre del archivo proporcionado como un argumento a este interruptor de línea de instrucción</li>
+<li>‘-e’ o ‘–eval’: evalúa el archivo tras abrirlo.</li>
+<li><code>-b</code> o <code>--batch</code>: si la línea de orden abre un archivo todas las celdas dentro de este archivo son evaluadas y el archivo es guardado después. Esto es por ejemplo útil si la sesión descrita dentro del archivo hace que <em>Maxima</em> genere archivos de salida. El guion de procesamiento será detenido si <em>wxMaxima</em> detecta que <em>Maxima</em> tiene un error de salida y lo detendrá si <em>Maxima</em> tiene una cuestión: las matemáticas es algo interactivo por naturaliza por lo que un proceso de guion libre de interacción no puede ser garantizado completamente.</li>
+<li><code>--logtostdout</code>: Registra todos los mensajes de la barra lateral “mensajes de depuración” a ‘stderr’, también.</li>
+<li><code>--pipe</code>: Conducto de mensajes desde ‘Maxima’ a ‘stdout’.</li>
+<li><code>--exit-on-error</code>: Cierra el programa en cualquier error de ‘maxima’.</li>
+<li><code>-f</code> o <code>--ini=&lt;cad&gt;</code>: Utiliza el archivo de ‘init’ que fue proporcionado como argumento a este intercambio de línea de instrucción.</li>
+<li><code>-u</code>, <code>--use-version=&lt;cad&gt;</code>: Utiliza la <code>&lt;cad&gt;</code> de la versión de ‘maxima’.</li>
+<li><code>-l</code>, <code>--lisp=&lt;cad&gt;</code>: Utiliza un compilador de ‘maxima’ compilado con Lisp <code>&lt;cad&gt;</code>.</li>
+<li><code>-X</code>, <code>--extra-args=&lt;cad&gt;</code>: Permite especificar argumentos adicionales de “Maxima”</li>
+<li><code>-m</code> o <code>--maxima=&lt;cad&gt;</code>: Permite especificar la ubicación del binario de <em>maxima</em></li>
+<li><code>--enableipc</code>: Permite que “Maxima” controle “wxMaxima” a través de comunicaciones de interprocesos. Utilice esa opción con cuidado.</li>
+<li><code>--wxmathml-lisp=&lt;cdn&gt;</code>: Ubicación de wxMathML.lisp (si no es el empotrado sería utilizado, mayormente para desarrolladores).</li>
 </ul>
-<p>En vez de un menos algunos sistemas operativos tal vez utilicen un guión al frente de las opciones de línea de instrucciones.</p>

+<h1 id="sobre-el-programa-contribuyendo-a-wxmaxima"><span class="header-section-number">8</span> Sobre el programa, contribuyendo a wxMaxima</h1>
+<p>wxMaxima es principalmente desarrollado utilizando el lenguaje de programación C++ utilizando el <a href="https://www.wxwidgets.org">marco de trabajo wxWidgets</a>, como sistema de compilación utilizamos <a href="https://www.cmake.org">CMake</a>, una parte pequeña escrita en Lisp. Puede contribuir al proyecto wxMaxima en <a href="https://github.com/wxMaxima-developers/wxmaxima" class="uri">https://github.com/wxMaxima-developers/wxmaxima</a>, si tiene conocimiento de estos lenguajes de programación y desea ayudar y contribuir al proyecto de software libre de wxMaxima.</p>
+<p>¡Pero no solamente los programadores son necesarios! Puede contribuir además a wxMaxima, si ayuda para mejorar la documentación, encontrar e informar defectos (y quizá repararlas), sugerir características nuevas, ayudar a traducir wxMaxima o el manual a su idioma (lea el README.md en el <a href="https://github.com/wxMaxima-developers/wxmaxima/tree/main/locales">subdirectorio de idioma</a> como wxMaxima y el manual puede ser traducido).</p>
+<p>O responda preguntas de otros usuarios en el foro de debate.</p>
+<p>El código fuente de wxMaxima está documentado utilizando Doxygen <a href="https://wxmaxima-developers.github.io/wxmaxima/Doxygen-documentation/">aquí</a>.</p>
+<p>El programa es casi autónomo, por tanto excepto para bibliotecas del sistema (y la biblioteca wxWidgets), ninguna dependencia externa (como archivos gráficos o la parte Lisp (el archivo <code>wxmathML.lisp</code>) es necesario, se incluyen estos archivos dentro del ejecutable.</p>
+<p>Si es un desarrollador, quizá desea intentar un archivo modificado de <code>wxmathML.lisp</code> sin tener que recompilar todo, uno puede utilizar la opción de línea de instrucción <code>--wxmathml-lisp=&lt;str&gt;</code> para utilizar otro archivo Lisp, no el incluido.</p>

 <p>In the open-source domain, big systems are normally split into smaller projects that are easier to handle for small groups of developers. For example a CD burner program will consist of a command-line tool that actually burns the CD and a graphical user interface that allows users to implement it without having to learn about all the command line switches and in fact without using the command line at all. One advantage of this approach is that the developing work that was invested into the command-line program can be shared by many programs: The same CD-burner command-line program can be used as a “send-to-CD”-plug-in for a file manager application, for the “burn to CD” function of a music player and as the CD writer for a DVD backup tool. Another advantage is that splitting one big task into smaller parts allows the developers to provide several user interfaces for the same program.</p>
 <p>A computer algebra system (CAS) like <em>Maxima</em> fits into this framework. A CAS can provide the logic behind an arbitrary precision calculator application or it can do automatic transforms of formulas in the background of a bigger system (e.g., <a href="https://www.sagemath.org/">Sage</a>). Alternatively, it can be used directly as a free-standing system. <em>Maxima</em> can be accessed via a command line. Often, however, an interface like <em>wxMaxima</em> proves a more efficient way to access the software, especially for newcomers.</p>

 <p><em>Maxima</em> is a full-featured computer algebra system (CAS). A CAS is a program that can solve mathematical problems by rearranging formulas and finding a formula that solves the problem as opposed to just outputting the numeric value of the result. In other words, <em>Maxima</em> can serve as a calculator that gives numerical representations of variables, and it can also provide analytical solutions. Furthermore, it offers a range of numerical methods of analysis for equations or systems of equations that cannot be solved analytically.</p>

 <p>Much of <em>wxMaxima</em> is self-explaining, but some details require attention. <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">This site</a> contains a number of workbooks that address various aspects of <em>wxMaxima</em>. Working through some of these (particularly the “10 minute <em>(wx)Maxima</em> tutorial”) will increase one’s familiarity with both the content of <em>Maxima</em> and the use of <em>wxMaxima</em> to interact with <em>Maxima</em>. This manual concentrates on describing aspects of <em>wxMaxima</em> that are not likely to be self-evident and that might not be covered in the online material.</p>
-<h3 id="the-workbook-approach"><span class="header-section-number">1.2.1</span> The workbook approach</h3>
-<p>One of the very few things that are not standard in <em>wxMaxima</em> is that it organizes the data for <em>Maxima</em> into cells that are evaluated (which means: sent to <em>Maxima</em>) only when the user requests this. When a cell is evaluated, all commands in that cell, and only that cell, are evaluated as a batch. (The preceding statement is not quite accurate: One can select a set of adjacent cells and evaluate them together. Also, one can instruct <em>Maxima</em> to evaluate all cells in a workbook in one pass.) <em>wxMaxima</em>’s approach to submitting commands for execution might feel unfamiliar at the first sight. It does, however, drastically ease work with big documents (where the user does not want every change to automatically trigger a full re-evaluation of the whole document). Also, this approach is very handy for debugging.</p>

 <p>If text is typed into <em>wxMaxima</em> it automatically creates a new worksheet cell. The type of this cell can be selected in the toolbar.

+<p>A <code>wxmx</code>-file seems to be a binary format, but one can handle it with tools, which are included in your OS. It is a zip file, one can decompress it with <code>unzip</code> (maybe rename it before, so that is recognized by the unzip program of your OS). We do not use the compression function, just the possibility to merge several files into one file - images are already compressed and the rest is simple text (probably much smaller, than huge images, which are included).</p>
+<p>It does contain the following files:</p>
+<ul>
+<li><code>mimetype</code>: this file does contain the mimetype of wxMaxima files: <code>text/x-wxmathml</code></li>
+<li><code>format.txt</code>: a short description about wxMaxima and the wxmx file format</li>
+<li>Images (e.g. png, jpeg): inline plots which were produced in the wxMaxima session and included images.</li>
+<li><code>content.xml</code>: a XML document, which contains the various cells of your document in XML format.</li>
+</ul>
+<p>So, if something goes wrong, you can unzip a wxMaxima document (maybe rename it before to a <code>zip</code>-file), maybe make changes in the <code>content.xml</code> file with a text editor, or replace an broken image, zip the files again, probably rename the <code>zip</code> to a <code>wxmx</code>-file - and you get another modified <code>wxmx</code>-file.</p>

 <p>If the <code>.wxmx</code> file format is being used embedding files in a <em>wxMaxima</em> project can be done as easily as per drag-and-drop. But sometimes (for example if an image’s contents might change later on in a session) it is better to tell the file to load the image on evaluation:</p>

Note that since <em>Maxima</em> is being run by a Lisp processor the process communication that is blocked from does not necessarily have to be named “maxima”. Common names of the program that opens the network connection would be sbcl, gcl, ccl, lisp.exe or similar names.</p>

 <p>And even if there isn’t such a file: The <code>.wxmx</code> file is a container format and the XML portion is stored uncompressed. It it is possible to rename the <code>.wxmx</code> file to a <code>.txt</code> file and to use a text editor to recover the XML portion of the file’s contents (it starts with <code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;</code> and ends with <code>&lt;/wxMaximaDocument&gt;</code>.

+<p>There seem to be issues with the Wayland Display Server and wxWidgets. WxMaxima may be affected, e.g. that sidebars are not moveable.</p>
+<p>You can either disable Wayland and use X11 instead (globally) or just tell, that wxMaxima should use the X Window System by setting: <code>GDK_BACKEND=x11</code></p>

+<h1 id="about-the-program-contributing-to-wxmaxima"><span class="header-section-number">8</span> About the program, contributing to wxMaxima</h1>
+<p>wxMaxima is mainly developed using the programming language C++ using the <a href="https://www.wxwidgets.org">wxWidgets framework</a>, as build system we use <a href="https://www.cmake.org">CMake</a>, a small part is written in Lisp. You can contribute to wxMaxima, join the wxMaxima project at <a href="https://github.com/wxMaxima-developers/wxmaxima" class="uri">https://github.com/wxMaxima-developers/wxmaxima</a>, if you have knowledge of these programming languages and want to help and contribute to the open source project wxMaxima.</p>
+<p>But not only programmers are necessary! You can also contribute to wxMaxima, if you help to improve the documentation, find and report bugs (and maybe bugfixes), suggest new features, help to translate wxMaxima or the manual to your language (read the README.md in the <a href="https://github.com/wxMaxima-developers/wxmaxima/tree/main/locales">locale subdirectory</a> how wxMaxima and the manual can be translated).</p>
+<p>Or answer questions of other users in the discussion forum.</p>
+<p>The source code of wxMaxima is documented using Doxygen <a href="https://wxmaxima-developers.github.io/wxmaxima/Doxygen-documentation/">here</a>.</p>
+<p>The program is nearly self-contained, so except for system libraries (and the wxWidgets library), no external dependencies (like graphic files or the Lisp part (the <code>wxmathML.lisp</code>-file) is needed, these files are included in the executable.</p>

-<p>Nel dominio open source, i grandi sistemi sono normalmente suddivisi in progetti più piccoli che sono più facili da gestire per piccoli gruppi di sviluppatori. Ad esempio, un programma di masterizzazione di CD sarà costituito da uno strumento a riga di comando che effettivamente masterizza il CD e da un’interfaccia utente grafica che consente agli utenti di utilizzarlo senza dover conoscere tutte le opzioni della riga di comando, e di fatto senza utilizzare affatto la riga di comando. Un vantaggio di questo approccio è che il lavoro di sviluppo che è stato investito nel programma a riga di comando può essere condiviso da molti programmi: lo stesso programma a riga di comando del masterizzatore CD può essere utilizzato come plug-in “invia-al-CD” per un’applicazione di gestione file, per la funzione “masterizza su CD” di un lettore musicale e come masterizzatore di CD per uno strumento di backup su DVD. Un altro vantaggio è che suddividere una grande attività in parti più piccole consente agli sviluppatori di fornire diverse interfacce utente per lo stesso programma.</p>

+<p>In the open-source domain, big systems are normally split into smaller projects that are easier to handle for small groups of developers. For example a CD burner program will consist of a command-line tool that actually burns the CD and a graphical user interface that allows users to implement it without having to learn about all the command line switches and in fact without using the command line at all. One advantage of this approach is that the developing work that was invested into the command-line program can be shared by many programs: The same CD-burner command-line program can be used as a âsend-to-CDâ-plug-in for a file manager application, for the âburn to CDâ function of a music player and as the CD writer for a DVD backup tool. Another advantage is that splitting one big task into smaller parts allows the developers to provide several user interfaces for the same program.</p>
 <p>Un sistema di algebra computazionale (CAS) come <em>Maxima</em> si inserisce in questo quadro. Un CAS può fornire la logica dietro un’applicazione di calcolatrice di precisione arbitraria o può fare trasformazioni automatiche di formule sullo sfondo di un sistema più grande (ad esempio, [Sage] (https://www.sagemath.org/)). In alternativa, può essere utilizzato direttamente come sistema indipendente. <em>Maxima</em> è utilizzabile tramite riga di comando. Spesso, tuttavia, un’interfaccia come <em>wxMaxima</em> si rivela un modo più efficiente per accedere al software, in particolare per i nuovi utenti.</p>

 <p><em>Maxima</em> è un sistema di algebra computazionale (CAS) completo. Un CAS è un programma in grado di risolvere problemi matematici riorganizzando le formule e trovando una formula che risolve il problema invece di emettere semplicemente il valore numerico del risultato. In altre parole, <em>Maxima</em> può fungere da calcolatrice che fornisce rappresentazioni numeriche di variabili e può anche fornire soluzioni analitiche. Inoltre, offre una gamma di metodi numerici di analisi per equazioni o sistemi di equazioni che non possono essere risolti analiticamente.</p>

-<p>Much of <em>wxMaxima</em> is self-explaining, but some details require attention. <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">This site</a> contains a number of workbooks that address various aspects of <em>wxMaxima</em>. Working through some of these (particularly the “10 minute <em>(wx)Maxima</em> tutorial”) will increase one’s familiarity with both the content of <em>Maxima</em> and the use of <em>wxMaxima</em> to interact with <em>Maxima</em>. This manual concentrates on describing aspects of <em>wxMaxima</em> that are not likely to be self-evident and that might not be covered in the online material.</p>
-<h3 id="the-workbook-approach"><span class="header-section-number">1.2.1</span> The workbook approach</h3>
-<p>One of the very few things that are not standard in <em>wxMaxima</em> is that it organizes the data for <em>Maxima</em> into cells that are evaluated (which means: sent to <em>Maxima</em>) only when the user requests this. When a cell is evaluated, all commands in that cell, and only that cell, are evaluated as a batch. (The preceding statement is not quite accurate: One can select a set of adjacent cells and evaluate them together. Also, one can instruct <em>Maxima</em> to evaluate all cells in a workbook in one pass.) <em>wxMaxima</em>’s approach to submitting commands for execution might feel unfamiliar at the first sight. It does, however, drastically ease work with big documents (where the user does not want every change to automatically trigger a full re-evaluation of the whole document). Also, this approach is very handy for debugging.</p>
-<p>If text is typed into <em>wxMaxima</em> it automatically creates a new worksheet cell. The type of this cell can be selected in the toolbar. If a code cell is created the cell can be sent to <em>Maxima</em>, which causes the result of the calculation to be displayed below the code. A pair of such commands is shown below.</p>

+<p>Se il testo viene digitato in <em>wxMaxima</em>, si crea automaticamente una nuova cella del foglio di lavoro. Il tipo di questa cella può essere selezionato nella barra degli strumenti. Se viene creata una cella di codice, la cella può essere inviata a <em>Maxima</em>, il che fa sì che il risultato del calcolo venga visualizzato sotto il codice. Di seguito viene mostrata una coppia di tali comandi.</p>

-<p>On evaluation of an input cell’s contents the input cell <em>Maxima</em> assigns a label to the input (by default shown in red and recognizable by the <code>%i</code>) by which it can be referenced later in the <em>wxMaxima</em> session. The output that <em>Maxima</em> generates also gets a label that begins with <code>%o</code> and by default is hidden, except if the user assigns the output a name. In this case by default the user-defined label is displayed. The <code>%o</code>-style label <em>Maxima</em> auto-generates will also be accessible, though.</p>
-<p>Besides the input cells <em>wxMaxima</em> allows for text cells for documentation, image cells, title cells, chapter cells and section cells. Every cell has its own undo buffer so debugging by changing the values of several cells and then gradually reverting the unneeded changes is rather easy. Furthermore the worksheet itself has a global undo buffer that can undo cell edits, adds and deletes.</p>
-<p>The figure below shows different cell types (title cells, section cells, subsection cells, text cells, input/output cells and image cells).</p>

+<p>A <code>wxmx</code>-file seems to be a binary format, but one can handle it with tools, which are included in your OS. It is a zip file, one can decompress it with <code>unzip</code> (maybe rename it before, so that is recognized by the unzip program of your OS). We do not use the compression function, just the possibility to merge several files into one file - images are already compressed and the rest is simple text (probably much smaller, than huge images, which are included).</p>
+<p>It does contain the following files:</p>
 <ul>
-<li>The configuration dialog box below lets you change their default values for the current and subsequent sessions.</li>
-<li>Also, the values for most configuration variables can be changed for the current session only by overwriting their values from the worksheet, as shown below.</li>
+<li><code>mimetype</code>: this file does contain the mimetype of wxMaxima files: <code>text/x-wxmathml</code> - <code>format.txt</code>: a short description about wxMaxima and the wxmx file format - Images (e.g. png, jpeg): inline plots which were produced in the wxMaxima session and included images. - <code>content.xml</code>: a XML document, which contains the various cells of your document in XML format.</li>
+</ul>
+<p>So, if something goes wrong, you can unzip a wxMaxima document (maybe rename it before to a <code>zip</code>-file), maybe make changes in the <code>content.xml</code> file with a text editor, or replace an broken image, zip the files again, probably rename the <code>zip</code> to a <code>wxmx</code>-file - and you get another modified <code>wxmx</code>-file.</p>

-<p>Since <em>Maxima</em> (the program that does the actual mathematics) and <em>wxMaxima</em> (providing the easy-to-use user interface) are separate programs that communicate by the means of a local network connection.

Note that since <em>Maxima</em> is being run by a Lisp processor the process communication that is blocked from does not necessarily have to be named “maxima”.

 <p>There are separate undo functions for cell operations and for changes inside of cells so chances are low that this ever happens. If it does there are several methods to recover data:</p>
 <ul>
-<li><em>wxMaxima</em> actually has two undo features: The global undo buffer that is active if no cell is selected and a per-cell undo buffer that is active if the cursor is inside a cell. It is worth trying to use both undo options in order to see if an old value can still be accessed.</li>
-<li>If you still have a way to find out what label <em>Maxima</em> has assigned to the cell just type in the cell’s label and its contents will reappear.</li>
-<li>If you don’t: Don’t panic. In the “View” menu there is a way to show a history pane that shows all <em>Maxima</em> commands that have been issued recently.</li>

+<h1 id="about-the-program-contributing-to-wxmaxima"><span class="header-section-number">8</span> About the program, contributing to wxMaxima</h1>
+<p>wxMaxima is mainly developed using the programming language C++ using the <a href="https://www.wxwidgets.org">wxWidgets framework</a>, as build system we use <a href="https://www.cmake.org">CMake</a>, a small part is written in Lisp. You can contribute to wxMaxima, join the wxMaxima project at <a href="https://github.com/wxMaxima-developers/wxmaxima" class="uri">https://github.com/wxMaxima-developers/wxmaxima</a>, if you have knowledge of these programming languages and want to help and contribute to the open source project wxMaxima.</p>
+<p>But not only programmers are necessary! You can also contribute to wxMaxima, if you help to improve the documentation, find and report bugs (and maybe bugfixes), suggest new features, help to translate wxMaxima or the manual to your language (read the README.md in the <a href="https://github.com/wxMaxima-developers/wxmaxima/tree/main/locales">locale subdirectory</a> how wxMaxima and the manual can be translated).</p>
+<p>Or answer questions of other users in the discussion forum.</p>
+<p>The source code of wxMaxima is documented using Doxygen <a href="https://wxmaxima-developers.github.io/wxmaxima/Doxygen-documentation/">here</a>.</p>
+<p>The program is nearly self-contained, so except for system libraries (and the wxWidgets library), no external dependencies (like graphic files or the Lisp part (the <code>wxmathML.lisp</code>-file) is needed, these files are included in the executable.</p>
+<p>If you are a developer, you might want to try out a modified <code>wxmathML.lisp</code>-file without recompiling everything, one can use the command line option <code>--wxmathml-lisp=&lt;str&gt;</code> to use another Lisp file, not the included one.</p>

-<p>In the open-source domain, big systems are normally split into smaller projects that are easier to handle for small groups of developers. For example a CD burner program will consist of a command-line tool that actually burns the CD and a graphical user interface that allows users to implement it without having to learn about all the command line switches and in fact without using the command line at all. One advantage of this approach is that the developing work that was invested into the command-line program can be shared by many programs: The same CD-burner command-line program can be used as a “send-to-CD”-plug-in for a file manager application, for the “burn to CD” function of a music player and as the CD writer for a DVD backup tool. Another advantage is that splitting one big task into smaller parts allows the developers to provide several user interfaces for the same program.</p>

 <p>A computer algebra system (CAS) like <em>Maxima</em> fits into this framework. A CAS can provide the logic behind an arbitrary precision calculator application or it can do automatic transforms of formulas in the background of a bigger system (e.g., <a href="https://www.sagemath.org/">Sage</a>). Alternatively, it can be used directly as a free-standing system. <em>Maxima</em> can be accessed via a command line. Often, however, an interface like <em>wxMaxima</em> proves a more efficient way to access the software, especially for newcomers.</p>

 <p><em>Maxima</em> tam özellikli bir ‘Sembolik’ olarak ta çalışabilen bir bilgisayar cebir sistemidir (BCS). Bir BCS, formülleri yeniden düzenleyerek ve sadece sonucun sayısal değerini çıkarmanın aksine problemi çözen bir formül bularak (sembolik ifadeler ile) matematiksel problemleri çözebilen bir programdır. Başka bir deyişle, <em>Maxima</em> değişkenlerin sayısal değerlerini veren bir hesap makinesi olarak kullanılabilir ve analitik çözümler de sağlayabilir. Ayrıca, analitik olarak çözülemeyen denklemler veya denklem sistemleri için bir dizi sayısal analiz yöntemi sunar.</p>

-<p>Much of <em>wxMaxima</em> is self-explaining, but some details require attention. <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">This site</a> contains a number of workbooks that address various aspects of <em>wxMaxima</em>. Working through some of these (particularly the “10 minute <em>(wx)Maxima</em> tutorial”) will increase one’s familiarity with both the content of <em>Maxima</em> and the use of <em>wxMaxima</em> to interact with <em>Maxima</em>. This manual concentrates on describing aspects of <em>wxMaxima</em> that are not likely to be self-evident and that might not be covered in the online material.</p>
-<h3 id="the-workbook-approach"><span class="header-section-number">1.2.1</span> The workbook approach</h3>
-<p>One of the very few things that are not standard in <em>wxMaxima</em> is that it organizes the data for <em>Maxima</em> into cells that are evaluated (which means: sent to <em>Maxima</em>) only when the user requests this. When a cell is evaluated, all commands in that cell, and only that cell, are evaluated as a batch. (The preceding statement is not quite accurate: One can select a set of adjacent cells and evaluate them together. Also, one can instruct <em>Maxima</em> to evaluate all cells in a workbook in one pass.) <em>wxMaxima</em>’s approach to submitting commands for execution might feel unfamiliar at the first sight. It does, however, drastically ease work with big documents (where the user does not want every change to automatically trigger a full re-evaluation of the whole document). Also, this approach is very handy for debugging.</p>

Also, this approach is very handy for debugging.</p>
 <p>If text is typed into <em>wxMaxima</em> it automatically creates a new worksheet cell. The type of this cell can be selected in the toolbar. If a code cell is created the cell can be sent to <em>Maxima</em>, which causes the result of the calculation to be displayed below the code. A pair of such commands is shown below.</p>
 <figure>
 <img src="./InputCell.png" alt="Input/output cell" id="img_InputCell" /><figcaption>Input/output cell</figcaption>

-<p>Bir girdi hücresinin içeriğinin değerlendirilmesinde, <em>Maxima</em> her girdi hücresinin başına <code>% i1,% i2,% i3</code> şeklinde bir etiket atar (varsayılan olarak kırmızı renkte gösterilir ), daha sonraki satırlarda bu satıra <code>% in (n; girdi satırı numarası) ifadesiyle _wxMaxima_ oturumunda atıfta bulunulabilir ve o satırdaki ifadeyi kullanabilirsiniz.(%i ifadesindeki 'i' input yani 'girdi'yi ifade eder) _Maxima_'ın oluşturduğu çıktı ayrıca, kullanıcı çıktıya bir ad ataması dışında,% o (buradaki 'o' output yani çıktı'yı ifade eder)ile başlayan bir etiket alır. Bu durumda varsayılan olarak kullanıcı tanımlı etiket görüntülenir. Yine de% o</code>  -style <em>Maxima</em> otomatik oluşturucu etiketine de erişilebilir. Çıktı satırları da ‘%on’ (n; çıktı satırı numarası) sonraki satırlarda bu satıra `% on (n; girdi satırı numarası) ifadesiyle <em>wxMaxima</em> oturumunda (geriye yönelik) atıfta bulunulabilir ve o satırdaki ifadeyi kullanabilirsiniz.</p>
+<p>On evaluation of an input cellâs contents the input cell <em>Maxima</em> assigns a label to the input (by default shown in red and recognizable by the <code>%i</code>) by which it can be referenced later in the <em>wxMaxima</em> session. The output that <em>Maxima</em> generates also gets a label that begins with <code>%o</code> and by default is hidden, except if the user assigns the output a name. In this case by default the user-defined label is displayed. The <code>%o</code>-style label <em>Maxima</em> auto-generates will also be accessible, though.</p>
 <p>Besides the input cells <em>wxMaxima</em> allows for text cells for documentation, image cells, title cells, chapter cells and section cells. Every cell has its own undo buffer so debugging by changing the values of several cells and then gradually reverting the unneeded changes is rather easy. Furthermore the worksheet itself has a global undo buffer that can undo cell edits, adds and deletes.</p>
 <p>The figure below shows different cell types (title cells, section cells, subsection cells, text cells, input/output cells and image cells).</p>

+<p>What isnât standard is that <em>wxMaxima</em> provides drag-and-drop flexibility by defining two types of cursors. <em>WxMaxima</em> will switch between them automatically when needed:</p>

+<p>A <code>wxmx</code>-file seems to be a binary format, but one can handle it with tools, which are included in your OS. It is a zip file, one can decompress it with <code>unzip</code> (maybe rename it before, so that is recognized by the unzip program of your OS). We do not use the compression function, just the possibility to merge several files into one file - images are already compressed and the rest is simple text (probably much smaller, than huge images, which are included).</p>
+<p>It does contain the following files:</p>
+<ul>
+<li><code>mimetype</code>: this file does contain the mimetype of wxMaxima files: <code>text/x-wxmathml</code> - <code>format.txt</code>: a short description about wxMaxima and the wxmx file format - Images (e.g. png, jpeg): inline plots which were produced in the wxMaxima session and included images. - <code>content.xml</code>: a XML document, which contains the various cells of your document in XML format.</li>
+</ul>
+<p>So, if something goes wrong, you can unzip a wxMaxima document (maybe rename it before to a <code>zip</code>-file), maybe make changes in the <code>content.xml</code> file with a text editor, or replace an broken image, zip the files again, probably rename the <code>zip</code> to a <code>wxmx</code>-file - and you get another modified <code>wxmx</code>-file.</p>

+<p><em>Maxima</em> normally instructs the external program <em>Gnuplot</em> to open a separate window for every diagram it creates. Since many times it is convenient to embed graphs into the worksheet instead <em>wxMaxima</em> provides its own set of plot functions that donât differ from the corresponding <em>maxima</em> functions save in their name: They are all prefixed by a âwxâ.</p>
+<p>The following plotting functions have wx-counterparts:</p>

+<p>As noted above, the configure dialog provides a way to change the default size plots created which sets the starting value of <code>wxplot_size</code>. The plotting routines of <em>wxMaxima</em> respect this variable that specifies the size of a plot in pixels. It can always be queried or used to set the size of the following plots:</p>

+<p>If the <code>.wxmx</code> file format is being used embedding files in a <em>wxMaxima</em> project can be done as easily as per drag-and-drop. But sometimes (for example if an imageâs contents might change later on in a session) it is better to tell the file to load the image on evaluation:</p>

 <p><em>WxMaxima</em>’ın yapılandırma iletişim kutusu, başlangıçta yürütülen komutlarla iki dosyayı düzenlemeyi önerir:</p>
 <ul>
-<li>A file that contains commands that are executed on starting up <em>Maxima</em>: <code>maxima-init.mac</code></li>
-<li>one file of additional commands that are executed if <em>wxMaxima</em> is starting <em>Maxima</em>: <code>wxmaxima-init.mac</code></li>

 </ul>
-<p>These files are in the Maxima user directory (usually <code>maxima</code> in Windows, <code>.maxima</code> otherwise) in the user’s home directory / user profile directory. The location can be found out with the command: <code>maxima_userdir;</code></p>
-<h2 id="special-variables-wx"><span class="header-section-number">2.6</span> Special variables wx…</h2>
+<p>For example, if Gnuplot is installed in <code>/opt</code> (maybe on MacOS), you can add <code>gnuplot_command:"/opt/local/bin/gnuplot"$</code> (or <code>/opt/gnuplot/bin/gnuplot</code> or any other path) to these files.</p>
+<p>These files are in the Maxima user directory (usually <code>%USERPROFILE%/maxima</code> in Windows, <code>$HOME/.maxima</code> otherwise). The location can be found out with the command: <code>maxima_userdir;</code></p>

 <ul>
-<li><code>wxsubscripts</code>, <em>Maxima</em> öğesine alt çizgi (<code>R_150</code> veya benzeri) içeren değişken adlarını abone değişkenlere dönüştürüp dönüştürmeyeceğini bildirir. Hangi değişken adlarının otomatik olarak dönüştürüldüğünü öğrenmek için `wxdeclare_subscript’e bakınız.</li>
-<li><code>wxfilename</code>: Bu değişken, şu anda <em>wxMaxima</em> içinde açılmış olan dosyanın adını içerir.</li>
-<li><code>wxdirname</code>: This variable contains the name the directory, in which the file currently opened in <em>wxMaxima</em> is.</li>
-<li><code>wxplot_pngcairo</code>, <em>wxMaxima</em>’nın <em>gnuplot</em>’ın daha fazla çizgi stili ve daha iyi bir genel grafik kalitesi sağlayan pngcairo terminali kullanmaya çalışıp çalışmadığını söyler.</li>

-<li><code>wxchangedir</code>: Çoğu işletim sisteminde <em>wxMaxima</em> <em>Maxima</em>’ın çalışma dizinini geçerli dosyanın dizinine otomatik olarak ayarlar. Bu, dosya G / Ç’sinin (ör. <code>Read_matrix</code> ile) okunması veya yazılması gereken dosyanın tam yolunu belirtmeden çalışmasını sağlar. Windows’ta bu özellik bazen hata mesajlarına neden olur ve bu nedenle yapılandırma iletişim kutusundan “false” olarak ayarlanabilir.</li>
-<li>“wxanimate_framerate”: Aşağıdaki animasyonların oynatılması gereken saniye başına kare sayısı.</li>
-<li>"wxanimate_autoplay`: Animasyonlar varsayılan olarak otomatik olarak oynatılsın mı?</li>
-<li><code>wxmaximaversion</code>: Returns the version number of <em>wxMaxima</em>.</li>
-<li><code>wxwidgetsversion</code>: Returns the wxWidgets version <em>wxMaxima</em> is using.</li>
+<li><code>wxsubscripts</code> tells <em>Maxima</em> if it should convert variable names that contain an underscore (<code>R_150</code> or the like) into subscripted variables. See <code>wxdeclare_subscript</code> for details which variable names are automatically converted. - <code>wxfilename</code>: This variable contains the name of the file currently opened in <em>wxMaxima</em>. - <code>wxdirname</code>: This variable contains the name the directory, in which the file currently opened in <em>wxMaxima</em> is. - <code>wxplot_pngcairo</code> tells whether <em>wxMaxima</em> tries to use _Gnuplot_âs pngcairo terminal that provides more line styles and a better overall graphics quality. - <code>wxplot_size</code> defines the resolution of embedded plots. - <code>wxchangedir</code>: On most operating systems <em>wxMaxima</em> automatically sets _Maxima_âs working directory to the directory of the current file. This allows file I/O (e.g. by <code>read_matrix</code>) to work without specifying the whole path to the file that has to be read or written. On Windows this feature sometimes causes error messages and therefore can be set to <code>false</code> from the config dialogue. - <code>wxanimate_framerate</code>: The number of frames per second the following animations have to be played back with. - <code>wxanimate_autoplay</code>: Automatically play animations by default? - <code>wxmaximaversion</code>: Returns the version number of <em>wxMaxima</em>. - <code>wxwidgetsversion</code>: Returns the wxWidgets version <em>wxMaxima</em> is using.</li>

-<li>Çizim komutu, “implicit_plot” gibi üçüncü taraf bir paketin parçasıdır, ancak bu paket, çizmeye çalışmadan önce <em>Maxima</em>’ın <code>load ()</code> komutu tarafından yüklenmedi.</li>
-<li><em>Maxima</em> tried to do something the currently installed version of <em>gnuplot</em> isn’t able to understand. In this case, a file ending in <code>.gnuplot</code> located in the directory, which <em>Maxima</em>’s variable <code>maxima_userdir</code> is pointing, contains the instructions from <em>Maxima</em> to <em>gnuplot</em>. Most of the time, this file’s contents therefore are helpful when debugging the problem.</li>
-<li>Gnuplot’a kenar yumuşatma ve ek çizgi stilleri sağlayan pngcairo kütüphanesini kullanması söylendi, ancak bu olasılığı desteklemek için derlenmedi. Çözüm: Yapılandırma iletişim kutusundaki “Çizim için cairo terminalini kullan” onay kutusunun işaretini kaldırın ve <em>Maxima</em>’dan <code>wxplot_pngcairo</code> değerini true olarak ayarlamayın.</li>
-<li>Gnuplot didn’t output a valid <code>.png</code> file.</li>
+<li>The plotting command is part of a third-party package like <code>implicit_plot</code> but this package was not loaded by _Maxima_âs <code>load()</code> command before trying to plot. - <em>Maxima</em> tried to do something the currently installed version of <em>Gnuplot</em> isnât able to understand. In this case, a file ending in <code>.gnuplot</code> located in the directory, which _Maxima_âs variable <code>maxima_userdir</code> is pointing, contains the instructions from <em>Maxima</em> to <em>Gnuplot</em>. Most of the time, this fileâs contents therefore are helpful when debugging the problem. - Gnuplot was instructed to use the pngCairo library that provides antialiasing and additional line styles, but it was not compiled to support this possibility. Solution: Uncheck the “Use the Cairo terminal for the plot” checkbox in the configuration dialog and donât set <code>wxplot_pngcairo</code> to true from <em>Maxima</em>. - Gnuplot didnât output a valid <code>.png</code> file.</li>

 <ul>
-<li><em>wxMaxima</em> aslında iki geri alma özelliğine sahiptir: Hiçbir hücre seçilmezse etkin olan genel geri alma arabelleği ve imleç bir hücrenin içindeyse etkin olan hücre başına geri alma arabelleği. Eski bir değere hala erişilip erişilemeyeceğini görmek için her iki geri alma seçeneğini kullanmaya değer.</li>
-<li>Hücreye <em>Maxima</em> etiketinin hangi etiketi atadığını bulmak için hala bir yolunuz varsa, hücrenin etiketini yazmanız yeterlidir ve içeriği yeniden görünür.</li>
-<li>Yapmazsanız: Panik yapmayın. “Görünüm” menüsünde, son zamanlarda verilen tüm <em>Maxima</em> komutlarını gösteren bir geçmiş bölmesi göstermenin bir yolu vardır.</li>
-<li>Başka bir şey yardımcı olmazsa <em>Maxima</em> bir yeniden oynatma özelliği içerir:</li>
+<li><em>WxMaxima</em> actually has two undo features: The global undo buffer that is active if no cell is selected and a per-cell undo buffer that is active if the cursor is inside a cell. It is worth trying to use both undo options in order to see if an old value can still be accessed. - If you still have a way to find out what label <em>Maxima</em> has assigned to the cell just type in the cellâs label and its contents will reappear. - If you donât: Donât panic. In the âViewâ menu there is a way to show a history pane that shows all <em>Maxima</em> commands that have been issued recently. - If nothing else helps <em>Maxima</em> contains a replay feature:</li>

When compiling a big software package like Lapack or dealing with extremely big lists or equations this limit might be too low. In order to extend the limits SBCL can be provided with the command line parameter <code>--dynamic-space-size</code> that tells SBCL how many megabytes it should reserve. A 32bit Windows-SBCL can reserve up to 999 Megabytes. A 64-bit SBCL version running on Windows can be instructed to use more than the about 1280 Megabytes compiling Lapack needs.</p>

+<p>One possible reason is that <em>Maxima</em> cannot be found in the location that is set in the âMaximaâ tab of _wxMaxima_âs configuration dialog and therefore wonât run at all. Setting the path to a working <em>Maxima</em> binary should fix this problem.</p>

 <li><code>-h</code> veya<code>--help</code>: Kısa bir yardım metni çıkarır</li>

 <li><code>-e</code> veya<code>--eval</code>: Dosyayı açtıktan sonra değerlendirin.</li>
-<li><code>-b</code> veya<code>--batch</code>: Komut satırı bir dosyayı açarsa, bu dosyadaki tüm hücreler değerlendirilir ve daha sonra dosya kaydedilir. Bu, örneğin, dosyada açıklanan oturum <em>Maxima</em> çıktı dosyaları oluşturuyorsa yararlıdır. <em>WxMaxima</em>, <em>Maxima</em> öğesinin bir hata verdiğini algılarsa ve <em>Maxima</em>’ın bir sorusu varsa duraklatılırsa, toplu işlem durdurulur: Matematik, doğası gereği biraz etkileşimlidir, bu nedenle tamamen etkileşimsiz bir toplu işlem her zaman garanti edilemez.</li>
+<li><code>-b</code> or <code>--batch</code>: If the command-line opens a file all cells in this file are evaluated and the file is saved afterward. This is for example useful if the session described in the file makes <em>Maxima</em> generate output files. Batch-processing will be stopped if <em>wxMaxima</em> detects that <em>Maxima</em> has output an error and will pause if <em>Maxima</em> has a question: Mathematics is somewhat interactive by nature so a completely interaction-free batch processing cannot always be guaranteed.</li>
 <li><code>--logtostderr</code>: Log all “debug messages” sidebar messages to stderr, too.</li>
 <li><code>--pipe</code>: Pipe messages from Maxima to stdout.</li>
 <li><code>--exit-on-error</code>: Close the program on any maxima error.</li>

+<h1 id="about-the-program-contributing-to-wxmaxima"><span class="header-section-number">8</span> About the program, contributing to wxMaxima</h1>
+<p>wxMaxima is mainly developed using the programming language C++ using the <a href="https://www.wxwidgets.org">wxWidgets framework</a>, as build system we use <a href="https://www.cmake.org">CMake</a>, a small part is written in Lisp. You can contribute to wxMaxima, join the wxMaxima project at <a href="https://github.com/wxMaxima-developers/wxmaxima" class="uri">https://github.com/wxMaxima-developers/wxmaxima</a>, if you have knowledge of these programming languages and want to help and contribute to the open source project wxMaxima.</p>
+<p>But not only programmers are necessary! You can also contribute to wxMaxima, if you help to improve the documentation, find and report bugs (and maybe bugfixes), suggest new features, help to translate wxMaxima or the manual to your language (read the README.md in the <a href="https://github.com/wxMaxima-developers/wxmaxima/tree/main/locales">locale subdirectory</a> how wxMaxima and the manual can be translated).</p>
+<p>Or answer questions of other users in the discussion forum.</p>
+<p>The source code of wxMaxima is documented using Doxygen <a href="https://wxmaxima-developers.github.io/wxmaxima/Doxygen-documentation/">here</a>.</p>
+<p>The program is nearly self-contained, so except for system libraries (and the wxWidgets library), no external dependencies (like graphic files or the Lisp part (the <code>wxmathML.lisp</code>-file) is needed, these files are included in the executable.</p>
+<p>If you are a developer, you might want to try out a modified <code>wxmathML.lisp</code>-file without recompiling everything, one can use the command line option <code>--wxmathml-lisp=&lt;str&gt;</code> to use another Lisp file, not the included one.</p>

-<p>У системі програмного забезпечення з відкритим кодом великі системи, зазвичай, діляться на менші проєкти, з якими простіше працювати невеликим групам розробників. Наприклад, програма для запису компакт-дисків складається з засобу командного рядка, який, власне, виконує запис компакт-диска, і графічного інтерфейсу користувача, за допомогою користувачі можуть виконати потрібні їм дії, не запам’ятовуючи параметрів командного рядка і, загалом, взагалі не маючи справи із командним рядком. Однією із переваг цього підходу є те, що робота з розробки засобу командного рядка може бути використана багатьма програмами: той самий засіб командного рядка для запису компакт-дисків можна використати у додатку надсилання даних на компакт-диск у програмі для керування файлами, для функції «записати на компакт-диск» у музичному програвачі та для запису компакт-диска у програмі для резервного копіювання на DVD. Ще однією перевагою є поділ одного великого завдання на менші частини, що надає змогу розробникам надавати декілька інтерфейсів користувача для однієї програми.</p>

+<p>In the open-source domain, big systems are normally split into smaller projects that are easier to handle for small groups of developers. For example a CD burner program will consist of a command-line tool that actually burns the CD and a graphical user interface that allows users to implement it without having to learn about all the command line switches and in fact without using the command line at all. One advantage of this approach is that the developing work that was invested into the command-line program can be shared by many programs: The same CD-burner command-line program can be used as a âsend-to-CDâ-plug-in for a file manager application, for the âburn to CDâ function of a music player and as the CD writer for a DVD backup tool. Another advantage is that splitting one big task into smaller parts allows the developers to provide several user interfaces for the same program.</p>
 <p>Система комп’ютерної алгебри (СКА), подібна до <em>Maxima</em>, дуже добре вкладається у цю схему. СКА може надавати логіку до програми-калькулятора із довільною точністю обчислень або може виконувати автоматичні перетворення форму у фоновому режимі для більших систем (наприклад, <a href="https://www.sagemath.org/">Sage</a>). Крім того, нею можна користуватися і безпосередньо, як самостійною системою. Доступ до <em>Maxima</em> можна отримати з командного рядка. Втім, часто інтерфейси, подібні до <em>wxMaxima</em>, є набагато ефективнішим способом доступу до програмного забезпечення, особливо для початківців.</p>

 <p><em>Maxima</em> є повноцінною системою комп’ютерної алгебри (СКА). СКА — програма, яка може розв’язувати математичні задачі перетворенням формул і визначенням формули, яка розв’язує задачу, замість простого виведення числової форми результату. Іншими словами, <em>Maxima</em> може слугувати калькулятором, який визначає числові значення змінних, а може давати аналітичні розв’язки. Крім того, у програмі передбачено багато обчислювальних методів для аналізу рівнянь і систем рівнянь, які не може бути розв’язано аналітично.</p>

-<p><em>wxMaxima</em> — графічний інтерфейс користувача, який надає доступ до усіх функціональних можливостей і гнучкості <em>Maxima</em>. <em>wxMaxima</em> надає у розпорядження користувачам графічні засоби роботи та можливості, які значно спрощують роботу з <em>Maxima</em>. Наприклад, у wxMaxima передбачено можливість експортування вмісту будь-якої комірки (або, якщо це потрібно, будь-якої частини формули) у форматі тексту, коду LaTeX або специфікації MathML простим клацанням правою кнопкою миші. Насправді, можна експортувати увесь робочий аркуш у форматі HTML або коду LaTeX.

+<p><em>WxMaxima</em> is a graphical user interface that provides the full functionality and flexibility of <em>Maxima</em>. WxMaxima offers users a graphical display and many features that make working with <em>Maxima</em> easier. For example <em>wxMaxima</em> allows one to export any cellâs contents (or, if that is needed, any part of a formula, as well) as text, as LaTeX or as MathML specification at a simple right-click. Indeed, an entire workbook can be exported, either as a HTML file or as a LaTeX file. Documentation for <em>wxMaxima</em>, including workbooks to illustrate aspects of its use, is online at the <em>wxMaxima</em> <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">help site</a>, as well as via the help menu.</p>

-<p>Призначення більшої частини інтерфейсу <em>wxMaxima</em> є очевидним, але деякі речі потребують більшої уваги. На <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">цьому сайті</a> можна знайти декілька робочих книг, які присвячено різноманітним аспектами роботи у <em>wxMaxima</em>. Опрацювання деяких з цих зразків (зокрема «Десятихвилинного підручника з <em>(wx)Maxima</em>») надасть змогу краще ознайомитися із роботою <em>Maxima</em> і використанням <em>wxMaxima</em> для взаємодії із <em>Maxima</em>. У цьому ж підручнику ми зосередимо увагу на описі тих аспектів <em>wxMaxima</em>, які, ймовірно, є неочевидними і про які немає відомостей у інтернет-підручнику.</p>
-<h3 id="використання-робочих-книг"><span class="header-section-number">1.2.1</span> Використання робочих книг</h3>
-<p>Однією із дуже небагатьох речей, які є нестандартними у <em>wxMaxima</em> є те, що дані для <em>Maxima</em> у програмі впорядковано за комірками, які обчислюються (тобто надсилаються до <em>Maxima</em>) лише на запит користувача. При обчисленні комірки усі команди у ній, і лише у ній, обчислюються пакетно. (Попереднє твердження є не зовсім точним: можна позначити набір сусідніх комірок і обчислити їх разом. Крім того, можна наказати <em>Maxima</em> обчислити усі комірки у робочій книзі одразу.) Підхід <em>wxMaxima</em> до надсилання команд на виконання може спочатку видатися незвичним. Втім, він значно спрощує роботу із великими документами (у яких користувач не хоче, щоб програма автоматично вмикала повне переобчислення усього документа у відповідь на будь-яку зміну). Крім того, такий підхід є дуже зручним для усування вад.</p>
+<h2 id="workbook-basics"><span class="header-section-number">2.2</span> Workbook basics</h2>
+<p>Much of <em>wxMaxima</em> is self-explaining, but some details require attention. <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">This site</a> contains a number of workbooks that address various aspects of <em>wxMaxima</em>. Working through some of these (particularly the “10 minute <em>(wx)Maxima</em> tutorial”) will increase oneâs familiarity with both the content of <em>Maxima</em> and the use of <em>wxMaxima</em> to interact with <em>Maxima</em>. This manual concentrates on describing aspects of <em>wxMaxima</em> that are not likely to be self-evident and that might not be covered in the online material.</p>
+<h3 id="the-workbook-approach"><span class="header-section-number">2.2.1</span> The workbook approach</h3>
+<p>One of the very few things that are not standard in <em>wxMaxima</em> is that it organizes the data for <em>Maxima</em> into cells that are evaluated (which means: sent to <em>Maxima</em>) only when the user requests this. When a cell is evaluated, all commands in that cell, and only that cell, are evaluated as a batch. (The preceding statement is not quite accurate: One can select a set of adjacent cells and evaluate them together. Also, one can instruct <em>Maxima</em> to evaluate all cells in a workbook in one pass.) _WxMaxima_âs approach to submitting commands for execution might feel unfamiliar at the first sight. It does, however, drastically ease work with big documents (where the user does not want every change to automatically trigger a full re-evaluation of the whole document). Also, this approach is very handy for debugging.</p>
 <p>Якщо ви почнете вводити якийсь текст у вікні <em>wxMaxima</em>, програма автоматично створить нову комірку робочого аркуша. Тип цієї комірки можна вибрати за допомогою панелі інструментів. Якщо створено комірку з кодом, її вміст може бути надіслано до <em>Maxima</em>. Результат обчислень буде показано під рядком коду. Пару таких команд показано нижче.</p>
 <figure>
 <img src="./InputCell.png" alt="Комірка введення-виведення" id="img_InputCell" /><figcaption>Комірка введення-виведення</figcaption>
 </figure>
-<p>При обчисленні вмісту комірки вхідних даних <em>Maxima</em> призначає мітку для вхідних даних (типово, таку мітку буде показано червоним кольором, вона матиме формат <code>%i</code>). За цією міткою можна посилатися на вміст далі у сеансі роботи з <em>wxMaxima</em>. Виведені <em>Maxima</em> дані також отримають мітку, яка починається з <code>%o</code>, і яку типово буде приховано, хіба що користувач надасть назву виведеними даним. Якщо надано назву, буде показано визначену користувачем мітку. Втім, можна буде користуватися і автоматично створеною <em>Maxima</em> міткою у стилі <code>%o</code>.</p>
+<p>On evaluation of an input cellâs contents the input cell <em>Maxima</em> assigns a label to the input (by default shown in red and recognizable by the <code>%i</code>) by which it can be referenced later in the <em>wxMaxima</em> session. The output that <em>Maxima</em> generates also gets a label that begins with <code>%o</code> and by default is hidden, except if the user assigns the output a name. In this case by default the user-defined label is displayed. The <code>%o</code>-style label <em>Maxima</em> auto-generates will also be accessible, though.</p>
 <p>Окрім комірок для вхідних даних, у <em>wxMaxima</em> передбачено комірки для документації, комірки зображень, комірки заголовків, комірки глав та комірки розділів. У кожної комірки є власний буфер скасовування дій, тому дуже просто діагностувати проблеми, змінюючи значення у комірках і поступово скасовуючи внесені зміни у різних комірках. Крім того, у самого робочого аркуша також є власний буфер скасовування дій, яким може скористатися для скасовування редагувань у комірках, додавання і вилучення комірок.</p>
 <p>На рисунку нижче показано різні типи комірок (комірки заголовків, комірки розділів, комірки підрозділів, текстові комірки, комірки введення-виведення та комірки зображення).</p>

+<h3 id="cells"><span class="header-section-number">2.2.2</span> Cells</h3>
+<p>Робочий аркуш складається з комірок. У wxMaxima передбачено такі типи комірок:</p>
 <ul>
-<li>Math cells, containing one or more lines of <em>Maxima</em> input.</li>
-<li>Output of, or a question from, <em>Maxima</em>.</li>
-<li>Image cells.</li>

 </ul>
 <p>Типовою поведінкою <em>wxMaxima</em> при введенні тексту є автоматичне створення комірки формули. Комірки інших типів можна створити за допомогою меню «Комірка», натискання клавіатурних скорочень для пунктів з цього меню або за допомогою спадного списку на панелі інструментів. Після створення нематематичної комірки усе, що введено у файл, вважатиметься текстом.</p>
-<p>A (C-style) comment text can be part of a math cell as follows: <code>/* This comment will be ignored by Maxima */</code></p>
-<p>“<code>/*</code>” marks the start of the comment, “<code>*/</code>” the end.</p>

+<p><a href="https://maxima.sourceforge.io/docs/manual/maxima_singlepage.html#Comments">Текст коментаря</a> (у стилі C) може бути частиною математичної комірки ось так: <code>/* Цей коментар буде проігноровано Maxima */</code></p>
+<p>«<code>/*</code>» позначає початок коментаря, «<code>*/</code>» — його кінець.</p>
+<h3 id="horizontal-and-vertical-cursors"><span class="header-section-number">2.2.3</span> Horizontal and vertical cursors</h3>
 <p>Якщо користувач намагається позначити ціле речення, текстовий процесор намагається розширити позначений фрагмент так, щоб він автоматично завершувався на початку і наприкінці слів. Так само, <em>wxMaxima</em>, якщо позначено декілька комірок, доповнюватиме позначений фрагмент до меж комірок.</p>
-<p>Нестандартною особливістю є те, що у <em>wxMaxima</em> передбачено гнучку систему перетягування зі скиданням, у якій визначено два типи курсорів. <em>wxMaxima</em> автоматично перемикатиметься між ними, коли у цьому виникатиме потреба:</p>
+<p>What isnât standard is that <em>wxMaxima</em> provides drag-and-drop flexibility by defining two types of cursors. <em>WxMaxima</em> will switch between them automatically when needed:</p>
 <ul>
-<li>Курсор буде намальовано горизонтально, якщо його пересунуто до проміжку між двома комірками, або якщо користувач клацнув кнопкою миші у проміжку між двома комірками.</li>
-<li>Вертикальний курсор, який працює у комірці. Цей курсор активується пересуванням курсора всередину комірки за допомогою вказівника миші або клавіш зі стрілками. Цей курсор працює подібно до курсора у текстовому редакторі.</li>
+<li>The cursor is drawn horizontally if it is moved in the space between two cells or by clicking there. - A vertical cursor that works inside a cell. This cursor is activated by moving the cursor inside a cell using the mouse pointer or the cursor keys and works much like the cursor in a text editor.</li>
 </ul>
-<p>When you start wxMaxima, you will only see the blinking horizontal cursor. If you start typing, a math cell will be automatically created and the cursor will change to a regular vertical one (you will see a right arrow as “prompt”, after the Math cell is evaluated (<kbd>CTRL+ENTER</kbd>), you will see the labels, e.g. <code>(%i1)</code>, <code>(%o1)</code>).</p>

-<p>You might want to create another cell type (using the “Cell” menu), maybe a title cell or text cell, which describes, what will be done, when you start creating your worksheet.</p>
-<p>If you navigate between the different cells, you will also see the (blinking) horizontal cursor, where you can insert a cell into your worksheet (either a math cell, by just start typing your formula - or another cell type using the menu).</p>
+<p>Ви можете створити комірки іншого типу (за допомогою меню «Комірка»), можливо, комірку заголовка та текстову комірку, яка описуватиме виконану математичну дію, коли почнете створення вашого робочого аркуша.</p>
+<p>Якщо ви переходитимете між різними комірками програма також показуватиме горизонтальний курсор, що блиматиме. На місці курсора ви можете вставити комірку до робочого аркуша (математичну комірку простим введенням формули або комірку іншого типу за допомогою меню).</p>

+<p>Besides completing a file name, a unit name, or the current command or variable name, the autocompletion is able to show a template for most of the commands indicating the type (and meaning) of the parameters this program expects. To activate this feature press <kbd>SHIFT</kbd>+<kbd>CTRL</kbd>+<kbd>SPACE</kbd> or select the respective menu item (Cell/Show Template).</p>
+<h4 id="greek-characters"><span class="header-section-number">2.2.5.1</span> Greek characters</h4>
 <p>Комп’ютери традиційно зберігають символи у форматі 8-бітових значень. Це уможливлює існування наборів, що складаються лише із 256 різних символів. У такий набір може бути включено усі літери, цифри та символи керування (завершення передавання, кінець рядка, лінії та кутики для малювання меню <em>тощо</em>) майже будь-якої європейської мови.</p>
 <p>Втім, у більшості мов до вибраної кодової сторінки із 256 символів не можна включити додаткові символи, зокрема літери грецької абетки, які широко використовуються у математичних формулах. Щоб подолати обмеження подібного типу, було винайдено <a href="https://home.unicode.org/">Юнікод</a> — кодування, яке працює для латиниці, але використовує набагато більше за 256 символів.</p>
-<p><em>Maxima</em> уможливлює використання символів Юнікоду, якщо програму було зібрано за допомогою компілятора Lisp, у якому передбачено підтримку Юнікоду або такого, який є нейтральним щодо кодування символів. Оскільки, хоча б одна з цих вимог, зазвичай, справджується, у <em>wxMaxima</em> реалізовано спосіб введення грецьких символів з клавіатури:</p>
+<p><em>Maxima</em> allows Unicode if it was compiled using a Lisp compiler that either supports Unicode or that doesnât care about the font encoding. As at least one of this pair of conditions is likely to be true. <em>WxMaxima</em> provides a method of entering Greek characters using the keyboard:</p>
 <ul>
-<li>Грецьку літеру можна ввести натисканням клавіші <kbd>ESC</kbd> з наступним введенням назви символу грецької абетки.</li>
-<li>Крім того, можна натиснути <kbd>ESC</kbd>, ввести одну літеру (чи дві літери для грецької літери «омікрон») і натиснути <kbd>ESC</kbd> ще раз. У цьому випадку прив’язка до літер є такою:</li>
+<li>A Greek letter can be entered by pressing the <kbd>ESC</kbd> key and then starting to type the Greek characterâs name. - Alternatively it can be entered by pressing <kbd>ESC</kbd>, one letter (or two for the Greek letter omicron) and <kbd>ESC</kbd> again. In this case the following letters are supported:</li>

+<p>Several Latin letters look like the Greek letters, e.g. the Latin letter “A” and the Greek letter “Alpha”. Although they look identical, they are two different Unicode characters, represented by different Unicode code points (numbers).</p>
+<p>This might be problematic, if you assign a value to the variable A and later use the Greek letter Alpha to do something with this variable, especially on printouts. For the Greek letter my (which is also used as prefix for micro) there are also two different Unicode code points.</p>
+<p>The “Greek letters”-sidebar therefore has the option, that lookalike characters are not available (which can be changed using a right-click menu).</p>

-<p>Отже, <kbd>ESC</kbd> <kbd>61</kbd> <kbd>ESC</kbd> дасть «a».</p>
-<p>Будь ласка, зауважте, що більшість цих символів (виключеннями є логічні символи) не мають спеціального значення у <em>Maxima</em> і тому можуть бути оброблені як звичайні символи. Якщо <em>Maxima</em> зібрано із Lisp, у якому не передбачено обробки символів Юнікоду, використання цих символів може призвести до показу повідомлення про помилку.</p>

+<p>Please note that most of these symbols (notable exceptions are the logic symbols) do not have a special meaning in <em>Maxima</em> and therefore will be interpreted as ordinary characters. If <em>Maxima</em> is compiled using a Lisp that doesnât support Unicode characters they might cause an error message.</p>

 <p>Матеріал, який було отримано під час сеансу роботи у <em>wxMaxima</em> може бути збережено для наступного використання у три способи:</p>
-<h3 id="mac"><span class="header-section-number">1.3.1</span> .mac</h3>
-<p>Файли <code>.mac</code> є звичайними текстовими файлами, які містять команди <em>Maxima</em>. Їх можна прочитати за допомогою команди <code>batch()</code> або <code>load()</code> <em>Maxima</em> або пункту меню «Файл/Пакетний файл».</p>
+<h3 id="mac"><span class="header-section-number">2.3.1</span> .mac</h3>
+<p><code>.mac</code> files are ordinary text files that contain <em>Maxima</em> commands. They can be read using _Maxima_âs <code>batch()</code> or <code>load()</code> command or _wxMaxima_âs File/Batch File menu entry.</p>
 <p>Один з прикладів наведено нижче. <code>Quadratic.mac</code> визначає функцію і після цього створює креслення за допомогою <code>wxdraw2d()</code>. Далі, буде виведено вміст файла <code>Quadratic.mac</code> і виконано обчислення нової визначеної функції <code>f()</code>.</p>
 <figure>
-<img src="./BatchImage.png" alt="Завантаження файла .mac за допомогою batch()" id="img_BatchImage" /><figcaption>Завантаження файла <code>.mac</code> за допомогою <code>batch()</code></figcaption>
+<img src="./BatchImage.png" alt="Loading a file with batch()" id="img_BatchImage" /><figcaption>Loading a file with <code>batch()</code></figcaption>
 </figure>
-<p>Увага! Хоча назва файла <code>Quadratic.mac</code> містить звичайний для <em>Maxima</em> суфікс (<code>.mac</code>), прочитати дані з нього зможе лише <em>wxMaxima</em>, оскільки команда <code>wxdraw2d()</code> є wxMaxima-розширенням до <em>Maxima</em>.</p>
-<p>Ви можете використовувати файли <code>.mac</code> для написання власної бібліотеки макросів. Але оскільки у них не міститься достатніх даних щодо структури, їх не можна читати як сеанс <em>wxMaxima</em>.</p>
-<h3 id="wxm"><span class="header-section-number">1.3.2</span> .wxm</h3>
-<p>Файли .wxm містять дані робочого аркуша, окрім виведених даних <em>Maxima</em>. У версіях Maxima &gt;5.38 їх можна прочитати за допомогою функції <code>load()</code> <em>Maxima</em>, так само, як можна прочитати файли .mac. У цьому текстовому форматі іноді є неусувна проблема — робочі аркуші із новими можливостями не є зворотно сумісними із застарілими версіями <em>wxMaxima</em>.</p>
-<h3 id="wxmx"><span class="header-section-number">1.3.3</span> .wxmx</h3>
+<p>Attention: Although the file <code>Quadratic.mac</code> has a usual <em>Maxima</em> extension (<code>.mac</code>), it can only be read by <em>wxMaxima</em>, since the command <code>wxdraw2d()</code> is a wxMaxima-extension to <em>Maxima</em>. (Command line) Maxima will ignore the unknown command <code>wxdraw2d()</code> and print it as output again.</p>
+<p>You can be use <code>.mac</code> files for writing your own library of macros. But since they donât contain enough structural information they cannot be read back as a <em>wxMaxima</em> session.</p>
+<h3 id="wxm"><span class="header-section-number">2.3.2</span> .wxm</h3>
+<p><code>.wxm</code> files contain the worksheet except for _Maxima_âs output. On Maxima versions &gt;5.38 they can be read using _Maxima_âs <code>load()</code> function just as .mac files can be. With this plain-text format, it sometimes is unavoidable that worksheets that use new features are not downwards-compatible with older versions of <em>wxMaxima</em>.</p>
+<h4 id="file-format-of-wxm-files"><span class="header-section-number">2.3.2.1</span> File format of wxm files</h4>
+<p>This is just a plain text file (you can open it with a text editor), containing the cell contents as some special Maxima comments.</p>
+<p>It starts with the following comment:</p>
+<p><code>/* [wxMaxima batch file version 1] [ DO NOT EDIT BY HAND! ]*/ /* [ Created with wxMaxima version 24.02.2_DevelopmentSnapshot ] */</code></p>
+<p>And then the cells follow, encoded as Maxima comments, e.g. a section cell:</p>
+<pre><code>/* [wxMaxima: section start ]
+Title of the section
+   [wxMaxima: section end   ] */</code></pre>
+<p>or (in a Math cell the input is of course <em>not</em> commented out (the output is not saved in a <code>wxm</code> file)):</p>
+<pre><code>/* [wxMaxima: input   start ] */
+f(x):=x^2+1$
+f(2);
+/* [wxMaxima: input   end   ] */</code></pre>
+<p>Images are <a href="https://en.wikipedia.org/wiki/Base64">Base64 encoded</a> with the image type as first line):</p>
+<pre><code>/* [wxMaxima: image   start ]
+jpg
+[very chaotic looking character sequence]
+   [wxMaxima: image   end   ] */</code></pre>
+<p>A page break is just one line containing:</p>
+<pre><code>/* [wxMaxima: page break    ] */</code></pre>
+<p>And folded cells marked by:</p>

 <p>У цьому заснованому на XML форматі файлів зберігається увесь робочий аркуш, включно із даними щодо масштабу та списком спостереження. Цей формат файлів є рекомендованим.</p>

+<h4 id="file-format-of-wxmx-files"><span class="header-section-number">2.3.3.1</span> File format of wxmx files</h4>
+<p>A <code>wxmx</code>-file seems to be a binary format, but one can handle it with tools, which are included in your OS. It is a zip file, one can decompress it with <code>unzip</code> (maybe rename it before, so that is recognized by the unzip program of your OS). We do not use the compression function, just the possibility to merge several files into one file - images are already compressed and the rest is simple text (probably much smaller, than huge images, which are included).</p>
+<p>It does contain the following files:</p>
+<ul>
+<li><code>mimetype</code>: this file does contain the mimetype of wxMaxima files: <code>text/x-wxmathml</code> - <code>format.txt</code>: a short description about wxMaxima and the wxmx file format - Images (e.g. png, jpeg): inline plots which were produced in the wxMaxima session and included images. - <code>content.xml</code>: a XML document, which contains the various cells of your document in XML format.</li>
+</ul>
+<p>So, if something goes wrong, you can unzip a wxMaxima document (maybe rename it before to a <code>zip</code>-file), maybe make changes in the <code>content.xml</code> file with a text editor, or replace an broken image, zip the files again, probably rename the <code>zip</code> to a <code>wxmx</code>-file - and you get another modified <code>wxmx</code>-file.</p>

 <p>Для деяких типових змінних налаштувань у <em>wxMaxima</em> передбачено два способи налаштовування:</p>
 <ul>
-<li>За допомогою діалогової панелі налаштовування, знімок якої наведено нижче, ви можете змінити типові значення для поточного і наступних сеансі роботи програми.</li>
-<li>Крім того, значення більшості змінних налаштувань може бути змінено лише для поточного сеансу перезаписуванням їхніх значень з робочого аркуша, як це показано нижче.</li>
+<li>The configuration dialog box below lets you change their default values for the current and subsequent sessions. - Also, the values for most configuration variables can be changed for the current session only by overwriting their values from the worksheet, as shown below.</li>

Визначити версію wxWidgets можна за допомогою команди <code>wxbuild_info();</code> або пункту меню «Довідка -&gt; Про програму». <a href="https://www.wxwidgets.org/">wxWidgets</a> є бібліотекою графічного інтерфейсу користувача, яка працює на багатьох платформах і є основою <em>wxMaxima</em> (звідси <code>wx</code> у назві програми). (Оскільки назви файлів починається з крапки, файл <code>.wxMaxima</code> і каталог<code>.config</code> є прихованими).</p>
+<h3 id="where-is-the-configuration-saved"><span class="header-section-number">2.4.5</span> Where is the configuration saved?</h3>
+<p>If you are using Unix/Linux, the configuration information will be saved in a file <code>.wxMaxima</code> in your home directory (if you are using wxWidgets &lt; 3.1.1), or <code>.config/wxMaxima.conf</code> ((XDG-Standard) if wxWidgets &gt;= 3.1.1 is used). You can retrieve the wxWidgets version from the command <code>wxbuild_info();</code> or by using the menu option Help-&gt;About. <a href="https://www.wxwidgets.org/">wxWidgets</a> is the cross-platform GUI library, which is the base for <em>wxMaxima</em> (therefore the <code>wx</code> in the name). (Since the filename starts with a dot, <code>.wxMaxima</code> or <code>.config</code> will be hidden).</p>
 <p>Якщо ви користуєтеся Windows, налаштування буде збережено у реєстрі. Записи <em>wxMaxima</em> можна знайти у цій гілці: <code>HKEY_CURRENT_USER\Software\wxMaxima</code></p>

-<h1 id="розширення-maxima"><span class="header-section-number">2</span> Розширення <em>Maxima</em></h1>
-<p>Основним призначенням <em>wxMaxima</em> є забезпечення графічного інтерфейсу до <em>Maxima</em>. Отже, основним завданням програми є передавання команд до <em>Maxima</em> і сповіщення користувача про результат виконання цих команд. Втім, у деяких випадках, <em>wxMaxima</em> розширює функціональні можливості <em>Maxima</em>. Ми вже згадували про здатність <em>wxMaxima</em> створювати звіти експортуванням вмісту робочої книги до файлів HTML і LaTeX. У цьому розділі ми розглянемо деякі способи, у які <em>wxMaxima</em> удосконалює включення графіки до сеансу.</p>
-<h2 id="змінні-із-індексами"><span class="header-section-number">2.1</span> Змінні із індексами</h2>
-<p>якщо встановлено значення true для <code>wxsubscripts</code>, назви змінних у форматі <code>x_y</code> буде показано як літеру із нижнім індексом, якщо</p>
+<h1 id="extensions-to-maxima"><span class="header-section-number">3</span> Extensions to <em>Maxima</em></h1>
+<p><em>WxMaxima</em> is primarily a graphical user interface for <em>Maxima</em>. As such, its main purpose is to pass along commands to <em>Maxima</em> and to report the results of executing those commands. In some cases, however, <em>wxMaxima</em> adds functionality to <em>Maxima</em>. _WxMaxima_âs ability to generate reports by exporting a workbookâs contents to HTML and LaTeX files has been mentioned. This section considers some ways that <em>wxMaxima</em> enhances the inclusion of graphics in a session.</p>
+<h2 id="subscripted-variables"><span class="header-section-number">3.1</span> Subscripted variables</h2>
+<p><code>wxsubscripts</code> визначає, чи <em>wxMaxima</em> виконуватиме автоматичне перетворення нижніх індексів у назвах змінних (і як вона це робитиме):</p>
+<p>Якщо має значення <code>false</code>, функціональну можливість буде вимкнено, wxMaxima не виконуватиме автоматичного перетворення частини назв змінної після символу підкреслення.</p>
+<p>If it is set to <code>'all</code>, everything after an underscore will be subscripted.</p>
+<p>Якщо встановлено значення <code>true</code> для <code>wxsubscripts</code>, назви змінних у форматі <code>x_y</code> буде показано як літеру із нижнім індексом, якщо</p>
 <ul>
-<li><code>y</code> є одинарною літерою</li>
-<li><code>y</code> є цілим числом</li>
+<li>Either <code>x</code> or <code>y</code> is a single letter or - <code>y</code> is an integer (can include more than one character).</li>
 </ul>
-<p>Якщо назва змінної не задовольняє ці вимоги, змінну все одно можна оголосити як змінну із нижнім індексом, за допомогою команди <code>wxdeclare_subscript(назва_змінної);</code> або <code>wxdeclare_subscript([назва_змінної1,назва_змінної2,...]);</code> Оголошення змінної як змінної із нижнім індексом можна скасувати за допомогою такої команди: <code>wxdeclare_subscript(назва_змінної,false);</code></p>

-<p>Команди, які виконуються довго, можуть надавати користувачам інформацію на смужці стану. Цю інформацію буде замінено на будь-яку нову інформацію, яку програма надсилатиме туди (це надає змогу використовувати смужку стану як індикатор поступу), і буде вилучено, щойно буде завершено виконання поточної команди, яку надіслано до <em>Maxima</em>. Команду <code>wxstatusbar()</code> можна безпечно використовувати навіть у бібліотеках, які може бути використано у звичайній <em>Maxima</em> (без <em>wxMaxima</em>): якщо <em>wxMaxima</em> немає, команда <code>wxstatusbar()</code> просто не оброблятиметься.</p>

+<p>If the variable name doesnât match these requirements, it can still be declared as “to be subscripted” using the command <code>wxdeclare_subscript(variable_name);</code> or <code>wxdeclare_subscript([variable_name1,variable_name2,...]);</code> Declaring a variable as subscripted can be reverted using the following command: <code>wxdeclare_subscript(variable_name,false);</code></p>

+<p>Long-running commands can provide user feedback in the status bar. This user feedback is replaced by any new feedback that is placed there (allowing to use it as a progress indicator) and is deleted as soon as the current command sent to <em>Maxima</em> is finished. It is safe to use <code>wxstatusbar()</code> even in libraries that might be used with plain <em>Maxima</em> (as opposed to <em>wxMaxima</em>): If <em>wxMaxima</em> isnât present the <code>wxstatusbar()</code> command will just be left unevaluated.</p>

 <p>Креслення (яке фундаментально пов’язано із графікою) є місцем, де графічний інтерфейс користувача має надавати якісь додаткові можливості до оригінальної програми.</p>

-<p>Зазвичай, <em>Maxima</em> наказує зовнішній програмі <em>gnuplot</em> відкривати окреме вікно для кожної створеної програмою діаграми. Оскільки набагато зручніше вбудовувати графіки безпосередньо до робочого аркуша, у <em>wxMaxima</em> передбачено власний набір команд для креслення, які не відрізняються від відповідних функцій <em>maxima</em> майже нічим, окрім назви: в усіх цих командах використано префікс «wx». Наприклад, команда <code>wxplot2d</code> відповідає команді <code>plot2d</code>, команда <code>wxplot3d</code> — команді <code>plot3d</code>, команда <code>wxdraw</code> — команді <code>draw</code>, а команда <code>wxhistogram</code> — команді <code>histogram</code>.</p>

-<p><em>Gnuplot</em>, здається, не надає придатного до портування на різні платформи способу визначення, чи передбачено у програмі підтримку виведення даних у форматі високоякісного растрового зображення з використанням бібліотеки cairo. У системах, де <em>gnuplot</em> зібрано з використанням відповідної бібліотеки, пункт pngcairo у меню налаштовування (який може бути перевизначено за допомогою змінної <code>wxplot_pngcairo</code>) вмикає підтримку згладжування та додаткових стилів ліній. Якщо встановлено <code>wxplot_pngcairo</code> без підтримки у <em>gnuplot</em>, результатом буде повідомлення про помилку замість графіка.</p>

+<p><em>Gnuplot</em> doesnât seem to provide a portable way of determining whether it supports the high-quality bitmap output that the Cairo library provides. On systems where <em>Gnuplot</em> is compiled to use this library the pngCairo option from the configuration menu (that can be overridden by the variable <code>wxplot_pngcairo</code>) enables support for antialiasing and additional line styles.

+<p>On MS Windows, there are two Gnuplot programs, <code>gnuplot.exe</code> and <code>wgnuplot.exe</code>. You can configure, which command should be used using the configuration menu. <code>wgnuplot.exe</code> offers the possibility to open a console window, where <em>gnuplot</em> commands can be entered into, <code>gnuplot.exe</code> does not offer this possibility.

-<h4 id="двовимірний"><span class="header-section-number">2.3.8.1</span> Двовимірний</h4>
-<p>Створює каркас команди <code>draw()</code>, яка малює плоску сцену. Цю сцену пізніше може бути заповнено за допомогою команд, які створюють вміст сцени, наприклад, за допомогою кнопок у рядках під кнопкою «Плоский».</p>

+<p>Generates the skeleton of a <code>draw()</code> command that draws a 2D scene. This scene later has to be filled with commands that generate the sceneâs contents, for example by using the buttons in the rows below the “2D” button.</p>
 <p>Однією з корисних можливостей кнопки «Плоский» є те, що вона надає змогу налаштувати сцену як анімацію, у якій змінна (типовою змінною є <em>t</em>) має різне значення для кожного з кадрів: часто динамічне плоске креслення надає змогу простіше інтерпретувати дані за ті самі у формі нерухомого просторового креслення.</p>

+<p>Especially when you use a high resolution display, the default font size might be very small. For the <code>draw</code>-based commands, you can set the font / font size using options like <code>font=...</code>, <code>font_size=...</code>, e.g.:</p>

+<p>For the <code>plot</code>-commands (e.g. <code>wxplot2d</code>, <code>wxplot3d</code>) font sizes and fonts can be set using the <code>gnuplot_preamble</code> command, e.g.:</p>
+<div class="sourceCode" id="cb19"><pre class="sourceCode maxima"><code class="sourceCode maxima"><a class="sourceLine" id="cb19-1" title="1"><span class="cn">wxplot2d</span>(<span class="fu">sin</span>(<span class="cn">x</span>),[<span class="cn">x</span>,<span class="dv">1</span>,<span class="dv">10</span>],</a>

+<p>This sets the font for the numbers to Arial with size 30, the size for the xlabel and ylabel font to 20 (with the default font).</p>
+<p>Read the Maxima and Gnuplot documentation for further information. Note: Gnuplot seems to have issues with larger font sizes, see <a href="https://github.com/wxMaxima-developers/wxmaxima/issues/1966">wxMaxima issue 1966</a>.</p>
+<h2 id="embedding-graphics"><span class="header-section-number">3.4</span> Embedding graphics</h2>
+<p>If the <code>.wxmx</code> file format is being used embedding files in a <em>wxMaxima</em> project can be done as easily as per drag-and-drop. But sometimes (for example if an imageâs contents might change later on in a session) it is better to tell the file to load the image on evaluation:</p>
+<p><code>maxima show_image("man.png");</code></p>
+<h2 id="startup-files"><span class="header-section-number">3.5</span> Startup files</h2>
 <p>У діалоговому вікні налаштовування <em>wxMaxima</em> передбачено можливість редагування двох файлів із командами, які виконуються під час запуску програми:</p>
 <ul>
-<li>Файла, у якому містяться команди, які виконуються під час запуску <em>Maxima</em>: <code>maxima-init.mac</code></li>
-<li>одного файла із додатковими командами, які виконуються, якщо <em>wxMaxima</em> запускає <em>Maxima</em>: <code>wxmaxima-init.mac</code></li>
+<li>A file that contains commands that are executed on starting up <em>Maxima</em>: <code>maxima-init.mac</code> - one file of additional commands that are executed if <em>wxMaxima</em> is starting <em>Maxima</em>: <code>wxmaxima-init.mac</code></li>
 </ul>
-<p>Ці файли зберігаються у каталозі користувача Maxima (зазвичай, каталозі <code>maxima</code> у Windows, <code>.maxima/</code> у інших системах) у домашній теці користувача. Розташування файлів можна визначити за допомогою такої команди: <code>maxima_userdir;</code></p>
-<h2 id="спеціальні-змінні-wx"><span class="header-section-number">2.6</span> Спеціальні змінні wx…</h2>
+<p>For example, if Gnuplot is installed in <code>/opt</code> (maybe on MacOS), you can add <code>gnuplot_command:"/opt/local/bin/gnuplot"$</code> (or <code>/opt/gnuplot/bin/gnuplot</code> or any other path) to these files.</p>
+<p>These files are in the Maxima user directory (usually <code>%USERPROFILE%/maxima</code> in Windows, <code>$HOME/.maxima</code> otherwise). The location can be found out with the command: <code>maxima_userdir;</code></p>
+<h2 id="special-variables-wx"><span class="header-section-number">3.6</span> Special variables wx…</h2>
 <ul>
-<li><code>wxsubscripts</code> вказує <em>Maxima</em>, чи слід перетворювати назви змінних, які містять символ підкреслювання (<code>R_150</code> або подібні змінні) на змінні із нижніми індексами. Див. <code>wxdeclare_subscript</code>, щоб дізнатися більше про те, які саме назви змінних буде перетворено автоматично.</li>
-<li><code>wxfilename</code>: у цій змінній зберігається назва файла, який зараз відкрито у <em>wxMaxima</em>.</li>
-<li><code>wxdirname</code>: This variable contains the name the directory, in which the file currently opened in <em>wxMaxima</em> is.</li>
-<li><code>wxplot_pngcairo</code> визначає те, чи намагатиметься <em>wxMaxima</em> скористатися терміналом pngcairo <em>gnuplot</em>, який надає доступ до ширшого вибору стилів ліній та кращої якості зображення.</li>
-<li><code>wxplot_size</code> визначає роздільну здатність для вбудованих креслень.</li>
-<li><code>wxchangedir</code>: у більшості операційних систем <em>wxMaxima</em> автоматично встановлює для робочого каталогу <em>Maxima</em> каталог поточного файла. Це уможливлює роботу введення-виведення до файла (наприклад, за допомогою <code>read_matrix</code>) без визначення усього шляху до файла, який має бути прочитано або записано. У Windows ця можливість іноді спричиняє повідомлення про помилку, тому варто встановити для цього параметра значення <code>false</code> у діалоговому вікні налаштовування.</li>

-<h2 id="не-вдається-зєднатися-із-maxima"><span class="header-section-number">3.1</span> Не вдається з’єднатися із <em>Maxima</em></h2>
-<p>Оскільки <em>Maxima</em> (програма, яка виконує самі обчислення) і <em>wxMaxima</em> (програма, яка надає простий у користуванні інтерфейс користувача) є окремими програмами, які обмінюються даними за допомогою з’єднання локальною мережею. Тому найімовірнішою причиною є те, що це з’єднання чомусь не працює. Наприклад, брандмауер може бути налаштовано таким чином, що він не просто запобігає неуповноваженим з’єднання з інтернету (і, можливо, також перехоплює з’єднання із інтернетом), але і блокує обмін даними між процесами на тому самому комп’ютері. Зауважте, що оскільки <em>Maxima</em> виконується процесором Lisp, процес. із яким блокується обмін даними, не обов’язково називається «maxima». Типовими назвами програм, які відкривають з’єднання мережі, можуть бути sbcl, gcl, ccl, lisp.exe або щось подібне.</p>
-<p>У системах Un*x іншою можливою причиною є те, що петльову мережу, яка забезпечує з’єднання мережі між двома програмам, які працюють на одному комп’ютері, не налаштовано належним чином.</p>
-<h2 id="як-зберегти-дані-із-пошкодженого-файла-.wxmx"><span class="header-section-number">3.2</span> Як зберегти дані із пошкодженого файла .wxmx</h2>
-<p>Internally most modern XML-based formats are ordinary zip-files. <em>wxMaxima</em> doesn’t turn on compression, so the contents of <code>.wxmx</code> files can be viewed in any text editor.</p>
-<p>If the zip signature at the end of the file is still intact after renaming a broken <code>.wxmx</code> file to <code>.zip</code> most operating systems will provide a way to extract any portion of information that is stored inside it. This can be done when there is the need of recovering the original image files from a text processor document. If the zip signature isn’t intact that does not need to be the end of the world: If <em>wxMaxima</em> during saving detected that something went wrong there will be a <code>.wxmx~</code> file whose contents might help.</p>
-<p>І навіть якщо такого файла не існує — якщо встановлено параметр налаштування для оптимізації файлів .wxmx для системи керування версіями, можна перейменувати файл .wxmx на файл .txt і скористатися текстовим редактором для відновлення частини XML із вмісту файла (він починається з <code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;</code> і завершується <code>&lt;/wxMaximaDocument&gt;</code>.

+<h2 id="cannot-connect-to-maxima"><span class="header-section-number">5.1</span> Cannot connect to <em>Maxima</em></h2>
+<p>Since <em>Maxima</em> (the program that does the actual mathematics) and <em>wxMaxima</em> (providing the easy-to-use user interface) are separate programs that communicate by the means of a local network connection. Therefore the most probable cause is that this connection is somehow not working. For example, a firewall could be set up in a way that it doesnât just prevent unauthorized connections from the internet (and perhaps intercept some connections to the internet, too), but also blocks inter-process-communication inside the same computer. Note that since <em>Maxima</em> is being run by a Lisp processor the process communication that is blocked does not necessarily have to be named “maxima”. Common names of the program that opens the network connection would be sbcl, gcl, ccl, lisp.exe, or similar names.</p>
+<p>On Unix computers another possible reason would be that the loopback network that provides network connections between two programs in the same computer isnât properly configured.</p>
+<h2 id="how-to-save-data-from-a-broken-.wxmx-file"><span class="header-section-number">5.2</span> How to save data from a broken .wxmx file</h2>
+<p>Internally most modern XML-based formats are ordinary zip files. <em>WxMaxima</em> doesnât turn on compression, so the contents of <code>.wxmx</code> files can be viewed in any text editor.</p>
+<p>If the zip signature at the end of the file is still intact after renaming a broken <code>.wxmx</code> file to <code>.zip</code> most operating systems will provide a way to extract any portion of the information that is stored inside it. This can be done when there is a need of recovering the original image files from a text processor document. If the zip signature isnât intact that does not need to be the end of the world: If <em>wxMaxima</em> during saving detected that something went wrong there will be a <code>.wxmx~</code> file whose contents might help.</p>
+<p>And even if there isnât such a file: The <code>.wxmx</code> file is a container format and the XML portion is stored uncompressed. It it is possible to rename the <code>.wxmx</code> file to a <code>.txt</code> file and to use a text editor to recover the XML portion of the fileâs contents (it starts with <code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;</code> and ends with <code>&lt;/wxMaximaDocument&gt;</code>. Before and after that text you will see some unreadable binary contents in the text editor).</p>
 <p>Якщо текстовий файл, що містить ці дані (наприклад скопійовані і вставлені як текст до звичайного файла), збережено як файл із суфіксом назви .xml, <em>wxMaxima</em> відомий спосіб відновлення тексту документа з цього файла.</p>

 <p>Зазвичай, <em>wxMaxima</em> очікує, доки буде передано усю двовимірну формулу, перш ніж починає виводити дані.

+<p>This means that <em>wxMaxima</em> could not read the file <em>Maxima</em> that was supposed to instruct <em>Gnuplot</em> to create.</p>
 <p>Можливими причинами цієї помилки є такі:</p>
 <ul>
-<li>Команда креслення є частиною стороннього пакунка, наприклад <code>implicit_plot</code>, але цей пакунок не було завантажено командою <code>load()</code> <em>Maxima</em> до того, як команду було передано на виконання.</li>
-<li><em>Maxima</em> спробувала зробити щось, що не змогла обробити поточна встановлена версія <em>gnuplot</em>. У цьому випадку, файл із суфіксом назви <code>.gnuplot</code> у каталозі, на який вказує змінна <em>Maxima</em> <code>maxima_userdir</code>, містить команди, які <em>Maxima</em> передавала <em>gnuplot</em>. Здебільшого, вміст цього файла є дуже корисним для діагностування проблеми.</li>
-<li>Gnuplot було наказано використовувати бібліотеку pngcairo, яка надає можливості згладжування зображення та додаткових стилів ліній, але саму програму не було зібрано із підтримкою цієї бібліотеки. Вирішення: зніміть позначку з пункту «Використовувати термінал cairo для креслення» у діалоговому вікні налаштувань і не встановлюйте для <code>wxplot_pngcairo</code> значення true з коду <em>Maxima</em>.</li>
-<li>Gnuplot не вивів коректного файла <code>.png</code>.</li>
+<li>The plotting command is part of a third-party package like <code>implicit_plot</code> but this package was not loaded by _Maxima_âs <code>load()</code> command before trying to plot. - <em>Maxima</em> tried to do something the currently installed version of <em>Gnuplot</em> isnât able to understand. In this case, a file ending in <code>.gnuplot</code> located in the directory, which _Maxima_âs variable <code>maxima_userdir</code> is pointing, contains the instructions from <em>Maxima</em> to <em>Gnuplot</em>. Most of the time, this fileâs contents therefore are helpful when debugging the problem. - Gnuplot was instructed to use the pngCairo library that provides antialiasing and additional line styles, but it was not compiled to support this possibility. Solution: Uncheck the “Use the Cairo terminal for the plot” checkbox in the configuration dialog and donât set <code>wxplot_pngcairo</code> to true from <em>Maxima</em>. - Gnuplot didnât output a valid <code>.png</code> file.</li>

 <p>У програмі передбачено окремі функції скасовування дій для дій з комірками і для дій усередині комірок, тому така подія має бути дуже рідкісною. Якщо таке все ж сталося, існує декілька способів відновити дані:</p>
 <ul>
-<li>У <em>wxMaxima</em> є два списки скасовування дій: загальний буфер скасовування, який є активним, якщо не позначено жодної комірки, та окремі буфери комірок, які є активним, якщо курсор перебуває у відповідній комірці. Варто спробувати скористатися обома варіантами скасовування, щоб спробувати дістатися потрібного вам попереднього значення.</li>
-<li>Якщо у вас лишився доступ до мітки, яку <em>Maxima</em> призначила комірці, просто введіть до комірки цю мітку, і програма покаже її вміст.</li>
-<li>Якщо доступу не лишилося, не панікуйте. У меню «Перегляд» є пункт для показу панелі журналу, на якій буде показано усі команди <em>Maxima</em>, які було нещодавно віддано.</li>
-<li>Якщо ніщо інше не допомагає, у <em>Maxima</em> є функція для відтворення усіх команд:</li>
+<li><em>WxMaxima</em> actually has two undo features: The global undo buffer that is active if no cell is selected and a per-cell undo buffer that is active if the cursor is inside a cell. It is worth trying to use both undo options in order to see if an old value can still be accessed. - If you still have a way to find out what label <em>Maxima</em> has assigned to the cell just type in the cellâs label and its contents will reappear. - If you donât: Donât panic. In the âViewâ menu there is a way to show a history pane that shows all <em>Maxima</em> commands that have been issued recently. - If nothing else helps <em>Maxima</em> contains a replay feature:</li>

-<p>Однією з можливих причин є те, що <em>Maxima</em> не вдалося знайти у каталозі, який вказано на сторінці «Maxima» діалогового вікна налаштовування <em>wxMaxima</em>, а отже, програму взагалі не запущено. Встановлення адреси коректного виконуваного файла <em>Maxima</em> має виправити цю проблему.</p>

+<p>One possible reason is that <em>Maxima</em> cannot be found in the location that is set in the âMaximaâ tab of _wxMaxima_âs configuration dialog and therefore wonât run at all. Setting the path to a working <em>Maxima</em> binary should fix this problem.</p>
+<h2 id="maxima-is-forever-calculating-and-not-responding-to-input"><span class="header-section-number">5.8</span> Maxima is forever calculating and not responding to input</h2>
+<p>It is theoretically possible that <em>wxMaxima</em> doesnât realize that <em>Maxima</em> has finished calculating and therefore never gets informed it can send new data to <em>Maxima</em>. If this is the case âTrigger evaluationâ might resynchronize the two programs.</p>

 <p>Компілятор Lisp SBCL типово позначається із обмеженням на використання пам’яті, яке надає змогу запускати його на слабких комп’ютерах. При компіляції великих пакунків програмного забезпечення, зокрема lapack, або роботі з великими списками або формулами це обмеження може заважати нормальній роботі. Щоб зняти обмеження, SBCL можна передати параметр <code>--dynamic-space-size</code>, який вказуватиме SBCL, скільки мегабайтів пам’яті слід зарезервувати. У 32-бітовому Windows-SBCL можна зарезервувати до 999 мегабайтів. У 64-бітовій версії SBCL, яку запущено у Windows, можна наказати програмі використовувати понад близько 1280 мегабайтів, чого має бути достатньо для збирання lapack.</p>
-<p>Одним зі способів передати <em>Maxima</em> (а отже, SBCL) параметри командного рядка є поле «Додаткові параметри для Maxima» вікна налаштовування <em>wxMaxima</em>.</p>
+<p>One way to provide <em>Maxima</em> (and thus SBCL) with command line parameters is the “Additional parameters for Maxima” field of _wxMaxima_âs configuration dialogue.</p>

Втім, колір тла можна змінити. Крім того, ви можете скористатися пунктом меню «Перегляд/Інвертувати яскравість робочого аркуша», за допомогою якого можна швидко перетворити робочий аркуш з темного на світлий, і навпаки.</p>

You can contribute to wxMaxima, join the wxMaxima project at <a href="https://github.com/wxMaxima-developers/wxmaxima" class="uri">https://github.com/wxMaxima-developers/wxmaxima</a>, if you have knowledge of these programming languages and want to help and contribute to the open source project wxMaxima.</p>
+<p>But not only programmers are necessary! You can also contribute to wxMaxima, if you help to improve the documentation, find and report bugs (and maybe bugfixes), suggest new features, help to translate wxMaxima or the manual to your language (read the README.md in the <a href="https://github.com/wxMaxima-developers/wxmaxima/tree/main/locales">locale subdirectory</a> how wxMaxima and the manual can be translated).</p>

-<p>在开源领域，大型项目通常被分割成小型项目，后者对于小规模开发组来说更容易处理。例如，一个 CD 刻录机程序会包括一个实际刻录 CD 的命令行程序和一个图形用户界面，该界面使得用户不必了解所有的命令行参数就能刻录 CD，从而实际上避开了使用命令行。这种方法的一个优点是，投入到命令行程序中的开发工作可以被许多程序共享：同一个刻录 CD 的命令行程序可以用作文件管理器应用程序的“发送到 CD”插件、音乐播放器的“刻录到 CD”功能以及 DVD 备份工具的刻录 CD 功能。另一个优点是将一个大型任务分解成更小的部分时，开发人员就可以为同一个程序提供多个用户界面。</p>

+<h2 id="maxima-and-wxmaxima"><span class="header-section-number">2.1</span> <em>Maxima</em> and wxMaxima</h2>
+<p>In the open-source domain, big systems are normally split into smaller projects that are easier to handle for small groups of developers. For example a CD burner program will consist of a command-line tool that actually burns the CD and a graphical user interface that allows users to implement it without having to learn about all the command line switches and in fact without using the command line at all. One advantage of this approach is that the developing work that was invested into the command-line program can be shared by many programs: The same CD-burner command-line program can be used as a âsend-to-CDâ-plug-in for a file manager application, for the âburn to CDâ function of a music player and as the CD writer for a DVD backup tool. Another advantage is that splitting one big task into smaller parts allows the developers to provide several user interfaces for the same program.</p>
 <p>一个像 Maxima 这样的计算机代数系统（CAS，computer algebra system）也适合前述框架。Maxima 可以用作任意精度计算器程序的底层软件，也可以在更大计算系统中作为公式转换程序来帮助计算（例如 <a href="https://www.sagemath.org/">Sage</a>）。Maxima 也可以直接作为独立的计算系统使用，它可以通过命令行来访问。然而，在通常情况下，像 wxMaxima 这样的用户界面是使用 Maxima 的一种更有效的方法，特别是对于新手而言更是如此。</p>

 <p>Maxima 是一个功能齐全的计算机代数系统（CAS）。CAS 是一个程序，它可以通过对公式变形并找到问题的解来求解数学问题，而不是仅仅输出结果的数值。换言之，Maxima 可以作为一个计算器，给出变量的数值表示，也可以提供解析解。此外，它还提供了一系列数值分析方法，用于求解没有解析解的方程或方程组。</p>

+<p><em>WxMaxima</em> is a graphical user interface that provides the full functionality and flexibility of <em>Maxima</em>. WxMaxima offers users a graphical display and many features that make working with <em>Maxima</em> easier. For example <em>wxMaxima</em> allows one to export any cellâs contents (or, if that is needed, any part of a formula, as well) as text, as LaTeX or as MathML specification at a simple right-click. Indeed, an entire workbook can be exported, either as a HTML file or as a LaTeX file. Documentation for <em>wxMaxima</em>, including workbooks to illustrate aspects of its use, is online at the <em>wxMaxima</em> <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">help site</a>, as well as via the help menu.</p>

-<h2 id="工作簿workbook基础"><span class="header-section-number">1.2</span> 工作簿（Workbook）基础</h2>
-<p>大部分 wxMaxima 功能是不言自明的，但有些细节需要注意。<a href="https://wxMaxima-developers.github.io/wxMaxima/help.html">这个网站</a>包含多个工作簿，这些工作簿涉及 wxMaxima 的各个方面。学习其中的一些（特别是“10 minute <em>(wx)Maxima</em> tutorial”，即“十分钟 (wx)Maxima 教程”）将增加用户对 Maxima 的内容和 wxMaxima 与 Maxima 交互过程的熟悉度。本手册集中描述 wxMaxima 的某些功能，这些功能可能并非不言而喻的，也可能不会被在线文档涵盖。</p>
-<h3 id="工作簿的使用"><span class="header-section-number">1.2.1</span> 工作簿的使用</h3>
-<p>wxMaxima 的特性之一是可以将发送给 Maxima 的命令提前组织到单元格中，这些单元格只在用户请求时才被处理（这意味着：把命令发送给 Maxima）。在处理单元格时，该单元格（且仅该单元格）中的所有命令将作为批处理进行计算。（前面的语句并不十分准确，因为可以选择一组相邻的单元格并且一起计算它们，或者让 Maxima 一次性算完工作簿中的所有单元格。）wxMaxima 提交命令的方法乍一看可能会觉得陌生。但是，这种做法确实大大简化了处理大型文档的工作（用户不希望每次更改都自动触发对整个文档的重新计算）。而且，该方法用于调试命令时非常方便。</p>
+<h2 id="workbook-basics"><span class="header-section-number">2.2</span> Workbook basics</h2>
+<p>Much of <em>wxMaxima</em> is self-explaining, but some details require attention. <a href="https://wxMaxima-developers.github.io/wxmaxima/help.html">This site</a> contains a number of workbooks that address various aspects of <em>wxMaxima</em>. Working through some of these (particularly the “10 minute <em>(wx)Maxima</em> tutorial”) will increase oneâs familiarity with both the content of <em>Maxima</em> and the use of <em>wxMaxima</em> to interact with <em>Maxima</em>. This manual concentrates on describing aspects of <em>wxMaxima</em> that are not likely to be self-evident and that might not be covered in the online material.</p>
+<h3 id="the-workbook-approach"><span class="header-section-number">2.2.1</span> The workbook approach</h3>
+<p>One of the very few things that are not standard in <em>wxMaxima</em> is that it organizes the data for <em>Maxima</em> into cells that are evaluated (which means: sent to <em>Maxima</em>) only when the user requests this. When a cell is evaluated, all commands in that cell, and only that cell, are evaluated as a batch. (The preceding statement is not quite accurate: One can select a set of adjacent cells and evaluate them together. Also, one can instruct <em>Maxima</em> to evaluate all cells in a workbook in one pass.) _WxMaxima_âs approach to submitting commands for execution might feel unfamiliar at the first sight. It does, however, drastically ease work with big documents (where the user does not want every change to automatically trigger a full re-evaluation of the whole document). Also, this approach is very handy for debugging.</p>
 <p>如果输入文本到 wxMaxima 中，则会自动创建一个新的工作簿单元格。可以在工具栏中选择此单元格的类型。如果创建了一个（数学）代码单元格，则可以将该单元格发送到 Maxima，这将使得计算结果显示在代码下方。下面显示了一对这样的命令：</p>
 <figure>
 <img src="./InputCell.png" alt="输入、输出单元格" id="img_InputCell" /><figcaption>输入、输出单元格</figcaption>
 </figure>
-<p>在计算（数学）输入单元格的内容时，Maxima 会为该输入指定一个标签（默认情况下以红色显示，并且可以由“%i”加数字识别），以便在 wxMaxima 会话的后续内容中引用该标签。Maxima 生成的输出也会获得以“%o”开头的标签，而当用户为输出指定了名称（如变量名）时，该标签是隐藏的。在后一种情况下，默认显示用户定义的名称。不过，此时仍可以访问 Maxima 自动生成的“%o”型标签。</p>
+<p>On evaluation of an input cellâs contents the input cell <em>Maxima</em> assigns a label to the input (by default shown in red and recognizable by the <code>%i</code>) by which it can be referenced later in the <em>wxMaxima</em> session. The output that <em>Maxima</em> generates also gets a label that begins with <code>%o</code> and by default is hidden, except if the user assigns the output a name. In this case by default the user-defined label is displayed. The <code>%o</code>-style label <em>Maxima</em> auto-generates will also be accessible, though.</p>
 <p>除了（数学）输入单元格外，wxMaxima 中还可以使用文本单元格、图片单元格、标题单元格、节单元格和小节单元格等。每个单元格都有独立的撤消缓冲区，因此通过更改多个单元格的内容，然后逐步撤销不需要的更改来进行调试，是非常容易的。此外，工作簿本身有一个全局撤消缓冲区，可以撤消单元格编辑、添加和删除操作。</p>
 <p>下图显示了不同的单元格类型（标题单元格、节单元格、小节单元格、文本单元格、输入/输出单元格和图片单元格）：</p>

-<p>在一般的文字处理程序中，如果用户试图选择多个行，该程序将尝试扩展选择范围，使其自动包括这些行的所有内容。类似地，在 wxMaxima 中，如果同时选择了多个单元格，则 wxMaxima 会将选择范围扩展到所有这些单元格的内容。</p>
-<p>与一般程序不同的是，wxMaxima 通过定义两种类型的光标，提供了操作灵活性。wxMaxima 将在需要时自动在它们之间切换：</p>
+<h3 id="horizontal-and-vertical-cursors"><span class="header-section-number">2.2.3</span> Horizontal and vertical cursors</h3>
+<p>If the user tries to select a complete sentence, a word processor will try to extend the selection to automatically begin and end with a word boundary. Likewise, if more than one cell is selected, <em>wxMaxima</em> will extend the selection to whole cells.</p>
+<p>What isnât standard is that <em>wxMaxima</em> provides drag-and-drop flexibility by defining two types of cursors. <em>WxMaxima</em> will switch between them automatically when needed:</p>
 <ul>
-<li>如果光标在两个单元格之间移动或单击，则会使用水平光标；</li>
-<li>如果在单元格内输入时，则会使用垂直光标。此种光标是当使用鼠标指针或方向键在单元格内移动光标时被激活的，与文本编辑器中光标的激活方式非常相似。</li>
+<li>The cursor is drawn horizontally if it is moved in the space between two cells or by clicking there. - A vertical cursor that works inside a cell. This cursor is activated by moving the cursor inside a cell using the mouse pointer or the cursor keys and works much like the cursor in a text editor.</li>
 </ul>
-<p>When you start wxMaxima, you will only see the blinking horizontal cursor. If you start typing, a math cell will be automatically created and the cursor will change to a regular vertical one (you will see a right arrow as “prompt”, after the Math cell is evaluated (<kbd>CTRL+ENTER</kbd>), you will see the labels, e.g. <code>(%i1)</code>, <code>(%o1)</code>).</p>

 <p>计算机一般以 8 位值（8-bit）存储字符，所以最多可以储存 256 个不同字符。大部分语言中的所有字母、数字和控制符号（传输结束、字符串结束、为菜单绘制矩形的线条和边缘等）都符合该限制。</p>
-<p>不过，对于大多数国家来说，256 个字符的代码页并没有包括希腊字母，而这些字母是数学上常用的。为了克服这种限制，<a href="https://home.unicode.org/">Unicode</a>被发明了：一种使英文文本储存方式不变的编码，可使用的字符数远超 256 个。</p>
-<p>如果使用支持 Unicode 或不关心字体编码的 Lisp 编译器来编译 Maxima，则在 Maxima 中可以使用 Unicode。前述两种情况中一般至少有一种是真的。wxMaxima 提供了一种使用键盘输入希腊字母的方法：</p>
+<p>For most countries, the codepage of 256 characters that has been chosen does not include things like Greek letters, though, that are frequently used in mathematics. To overcome this type of limitation <a href="https://home.unicode.org/">Unicode</a> has been invented: An encoding that makes English text work like normal, but to use much more than 256 characters.</p>
+<p><em>Maxima</em> allows Unicode if it was compiled using a Lisp compiler that either supports Unicode or that doesnât care about the font encoding. As at least one of this pair of conditions is likely to be true. <em>WxMaxima</em> provides a method of entering Greek characters using the keyboard:</p>
 <ul>
-<li>可以通过按下 <kbd>ESC</kbd> 键，然后开始键入希腊字母的英文名称来输入该字母。</li>
-<li>或者，也可以通过按下 <kbd>ESC</kbd>、一个英文字母（对希腊字母 omicron 而言是两个）并再次按下 <kbd>ESC</kbd> 来输入。在这种情况下，支持以下字母：</li>
+<li>A Greek letter can be entered by pressing the <kbd>ESC</kbd> key and then starting to type the Greek characterâs name. - Alternatively it can be entered by pressing <kbd>ESC</kbd>, one letter (or two for the Greek letter omicron) and <kbd>ESC</kbd> again.

-<p><code>.wxm</code> 文件包含除 Maxima 输出之外的工作簿内容。在版本号大于 5.38 的 Maxima 上，可以像 <code>.mac</code> 文件一样，使用 Maxima 的 <code>load()</code> 函数来读取。如果采用这种文本格式，使用含新功能的工作簿时会不可避免地与旧版本的 wxMaxima 不兼容。</p>

+<h4 id="file-format-of-wxmx-files"><span class="header-section-number">2.3.3.1</span> File format of wxmx files</h4>
+<p>A <code>wxmx</code>-file seems to be a binary format, but one can handle it with tools, which are included in your OS. It is a zip file, one can decompress it with <code>unzip</code> (maybe rename it before, so that is recognized by the unzip program of your OS). We do not use the compression function, just the possibility to merge several files into one file - images are already compressed and the rest is simple text (probably much smaller, than huge images, which are included).</p>
+<p>It does contain the following files:</p>
+<ul>
+<li><code>mimetype</code>: this file does contain the mimetype of wxMaxima files: <code>text/x-wxmathml</code> - <code>format.txt</code>: a short description about wxMaxima and the wxmx file format - Images (e.g. png, jpeg): inline plots which were produced in the wxMaxima session and included images. - <code>content.xml</code>: a XML document, which contains the various cells of your document in XML format.</li>
+</ul>
+<p>So, if something goes wrong, you can unzip a wxMaxima document (maybe rename it before to a <code>zip</code>-file), maybe make changes in the <code>content.xml</code> file with a text editor, or replace an broken image, zip the files again, probably rename the <code>zip</code> to a <code>wxmx</code>-file - and you get another modified <code>wxmx</code>-file.</p>

You can retrieve the wxWidgets version from the command <code>wxbuild_info();</code> or by using the menu option Help-&gt;About. <a href="https://www.wxwidgets.org/">wxWidgets</a> is the cross-platform GUI library, which is the base for <em>wxMaxima</em> (therefore the <code>wx</code> in the name). (Since the filename starts with a dot, <code>.wxMaxima</code> or <code>.config</code> will be hidden).</p>

-<p>wxMaxima 是 Maxima 的图形用户界面，因此它的主要目的是将命令传递给 Maxima，并输出执行这些命令的结果。但是，在某些情况下，wxMaxima 会为 Maxima 添加新的功能。前面已提到 wxMaxima 可以将工作簿的内容导出为 HTML 和 LaTeX 文件。本节将讨论另外一些增强功能，以及在工作簿中包含图形的方法。</p>
-<h2 id="为变量添加下标"><span class="header-section-number">2.1</span> 为变量添加下标</h2>
-<p>如果 <code>wxsubscripts</code> 设置为 true，则当以下条件满足时，将使用下标来显示格式为 <code>x_y</code> 的变量名：</p>
+<h1 id="extensions-to-maxima"><span class="header-section-number">3</span> Extensions to <em>Maxima</em></h1>
+<p><em>WxMaxima</em> is primarily a graphical user interface for <em>Maxima</em>. As such, its main purpose is to pass along commands to <em>Maxima</em> and to report the results of executing those commands. In some cases, however, <em>wxMaxima</em> adds functionality to <em>Maxima</em>. _WxMaxima_âs ability to generate reports by exporting a workbookâs contents to HTML and LaTeX files has been mentioned. This section considers some ways that <em>wxMaxima</em> enhances the inclusion of graphics in a session.</p>
+<h2 id="subscripted-variables"><span class="header-section-number">3.1</span> Subscripted variables</h2>
+<p><code>wxsubscripts</code> specifies, if (and how) <em>wxMaxima</em> will autosubscript variable names:</p>
+<p>If it is <code>false</code>, the functionality is off, wxMaxima will not autosubscript part of variable names after an underscore.</p>
+<p>If it is set to <code>'all</code>, everything after an underscore will be subscripted.</p>
+<p>If it is set to <code>true</code> variable names of the format <code>x_y</code> are displayed using a subscript if</p>
 <ul>
-<li><code>y</code> 是一个字母；</li>
-<li><code>y</code> 是一个整数。</li>
+<li>Either <code>x</code> or <code>y</code> is a single letter or - <code>y</code> is an integer (can include more than one character).</li>
 </ul>
-<p>如果变量格式与上述条件不匹配，仍可以使用命令<code>wxdeclare_subscript(variable_name);</code> 或 <code>wxdeclare_subscript([variable_name1,variable_name2,...]);</code>来显示下标。声明为下标的变量可以使用以下命令还原格式：<code>wxdeclare_subscript(variable_name,false);</code>。</p>
-<h2 id="在状态栏中提供反馈信息"><span class="header-section-number">2.2</span> 在状态栏中提供反馈信息</h2>
-<p>长时间运行的命令中可以包含 <code>wxstatusbar()</code>，以用于在状态栏中向用户提供反馈信息。此反馈信息将被任何新生成的反馈信息覆盖（从而可以将其用作运行进度指示器），并在发送到 Maxima 的命令运行结束后立即被删除。即使在只与 Maxima（而非 wxMaxima）一起使用的库中包含命令 <code>wxstatusbar()</code> 也是可行的：如果没有运行 wxMaxima，那么命令 <code>wxstatusbar()</code> 也不会被执行。</p>

+<p>If the variable name doesnât match these requirements, it can still be declared as “to be subscripted” using the command <code>wxdeclare_subscript(variable_name);</code> or <code>wxdeclare_subscript([variable_name1,variable_name2,...]);</code> Declaring a variable as subscripted can be reverted using the following command: <code>wxdeclare_subscript(variable_name,false);</code></p>

It is safe to use <code>wxstatusbar()</code> even in libraries that might be used with plain <em>Maxima</em> (as opposed to <em>wxMaxima</em>): If <em>wxMaxima</em> isnât present the <code>wxstatusbar()</code> command will just be left unevaluated.</p>

+<p>Setting the size of embedded plot with <code>wxplot_size</code> works for embedded plots using e.g. <code>wxplot</code>, <code>wxdraw</code>, <code>wxcontour_plot</code> and <code>wximplicit_plot</code> commands and for embedded animations with <code>with_slider_draw</code> and <code>wxanimate</code> commands.</p>

+<p><em>Gnuplot</em> doesnât seem to provide a portable way of determining whether it supports the high-quality bitmap output that the Cairo library provides. On systems where <em>Gnuplot</em> is compiled to use this library the pngCairo option from the configuration menu (that can be overridden by the variable <code>wxplot_pngcairo</code>) enables support for antialiasing and additional line styles. If <code>wxplot_pngCairo</code> is set without <em>Gnuplot</em> supporting this the result will be error messages instead of graphics.</p>

+<p>If a plot was generated using the <code>wxdraw</code>-type commands (<code>wxplot2d</code> and <code>wxplot3d</code> isnât supported by this feature) and the file size of the underlying <em>Gnuplot</em> project isnât way too high <em>wxMaxima</em> offers a right-click menu that allows to open the plot in an interactive <em>Gnuplot</em> window.</p>

+<p>On MS Windows, there are two Gnuplot programs, <code>gnuplot.exe</code> and <code>wgnuplot.exe</code>. You can configure, which command should be used using the configuration menu. <code>wgnuplot.exe</code> offers the possibility to open a console window, where <em>gnuplot</em> commands can be entered into, <code>gnuplot.exe</code> does not offer this possibility. Unfortunately, <code>wgnuplot.exe</code> causes <em>Gnuplot</em> to “steal” the keyboard focus for a short time every time a plot is prepared.</p>

+<p>3D diagrams tend to make it hard to read quantitative data. A viable alternative might be to assign the 3rd parameter to the mouse wheel. The <code>with_slider_draw</code> command is a version of <code>wxdraw2d</code> that does prepare multiple plots and allows to switch between them by moving the slider on top of the screen. <em>WxMaxima</em> allows to export this animation as an animated gif.</p>
 <p><code>with_slider_draw</code> 命令的前两个参数是用于控制绘图的变量名称和变量值的列表，接下来的参数与 <code>wxdraw2d</code> 命令的参数相同：</p>

-<li><code>wxplot_pngcairo</code>：表明 wxMaxima 是否尝试使用 gnuplot 的 pngcairo 功能，以提供更多的线条样式和更好的整体图形质量。</li>
-<li><code>wxplot_size</code>：定义嵌入绘图的分辨率。</li>
-<li><code>wxchangedir</code>：在大多数操作系统上，wxMaxima 自动将 Maxima 的工作目录设置为当前文件的目录。这允许文件 I/O（例如通过 <code>read_matrix</code>）工作，而无需指定必须读或写的文件的整个路径。在 Windows 操作系统上，此功能有时会导致错误消息，因此可以在设置对话框中将其设置为 <code>false</code>。</li>
-<li><code>wxanimate_framerate</code>：下一个动图回放的帧率。</li>
-<li><code>wxanimate_autoplay</code>：是否在默认情况下自动播放动图。</li>

-<li><code>wxwidgetsversion</code>: Returns the wxWidgets version <em>wxMaxima</em> is using.</li>
+<li><code>wxsubscripts</code> tells <em>Maxima</em> if it should convert variable names that contain an underscore (<code>R_150</code> or the like) into subscripted variables. See <code>wxdeclare_subscript</code> for details which variable names are automatically converted. - <code>wxfilename</code>: This variable contains the name of the file currently opened in <em>wxMaxima</em>. - <code>wxdirname</code>: This variable contains the name the directory, in which the file currently opened in <em>wxMaxima</em> is. - <code>wxplot_pngcairo</code> tells whether <em>wxMaxima</em> tries to use _Gnuplot_âs pngcairo terminal that provides more line styles and a better overall graphics quality. - <code>wxplot_size</code> defines the resolution of embedded plots. - <code>wxchangedir</code>: On most operating systems <em>wxMaxima</em> automatically sets _Maxima_âs working directory to the directory of the current file. This allows file I/O (e.g. by <code>read_matrix</code>) to work without specifying the whole path to the file that has to be read or written. On Windows this feature sometimes causes error messages and therefore can be set to <code>false</code> from the config dialogue. - <code>wxanimate_framerate</code>: The number of frames per second the following animations have to be played back with. - <code>wxanimate_autoplay</code>: Automatically play animations by default? - <code>wxmaximaversion</code>: Returns the version number of <em>wxMaxima</em>. - <code>wxwidgetsversion</code>: Returns the wxWidgets version <em>wxMaxima</em> is using.</li>

-<h2 id="无法连接到-maxima"><span class="header-section-number">3.1</span> 无法连接到 Maxima</h2>
-<p>由于 Maxima（进行实际数学运算的程序）和 wxMaxima（提供易于使用的用户界面的程序）是通过本地网络连接进行通信的独立程序，因此，最有可能的原因是这种连接不起作用。例如，可能设置了防火墙不仅可以阻止来自互联网的未经授权的连接（也许还会拦截一些通向互联网的连接），而且可以阻止同一台计算机内部的进程间通信。注意，由于 Maxima 由 Lisp 语言处理程序运行，因此被阻止的通信进程不一定命名为“Maxima”。此时打开网络连接的程序名称可能是 sbcl、gcl、ccl、lisp.exe 或者类似的名字。</p>
-<p>在 Un*x 系统上，另一个可能的原因是在同一台计算机上的两个程序之间提供网络连接的环回（loopback）网络配置不正确。</p>

-<p>Internally most modern XML-based formats are ordinary zip-files. <em>wxMaxima</em> doesn’t turn on compression, so the contents of <code>.wxmx</code> files can be viewed in any text editor.</p>
-<p>If the zip signature at the end of the file is still intact after renaming a broken <code>.wxmx</code> file to <code>.zip</code> most operating systems will provide a way to extract any portion of information that is stored inside it. This can be done when there is the need of recovering the original image files from a text processor document. If the zip signature isn’t intact that does not need to be the end of the world: If <em>wxMaxima</em> during saving detected that something went wrong there will be a <code>.wxmx~</code> file whose contents might help.</p>
-<p>即使没有 <code>.wxmx~</code> 文件，<code>.wxmx</code> 文件中 XML 部分是未压缩的，可以将该文件重命名为 <code>.txt</code> 文件，并使用文本编辑器恢复文件中的 XML 部分（以 <code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;</code> 开头，并以 <code>&lt;/wxMaximaDocument&gt;</code> 结尾（在 XML 部分的前后，可在文本编辑器中看到一些不可读的二进制内容）。</p>

+<h2 id="cannot-connect-to-maxima"><span class="header-section-number">5.1</span> Cannot connect to <em>Maxima</em></h2>
+<p>Since <em>Maxima</em> (the program that does the actual mathematics) and <em>wxMaxima</em> (providing the easy-to-use user interface) are separate programs that communicate by the means of a local network connection. Therefore the most probable cause is that this connection is somehow not working. For example, a firewall could be set up in a way that it doesnât just prevent unauthorized connections from the internet (and perhaps intercept some connections to the internet, too), but also blocks inter-process-communication inside the same computer. Note that since <em>Maxima</em> is being run by a Lisp processor the process communication that is blocked does not necessarily have to be named “maxima”. Common names of the program that opens the network connection would be sbcl, gcl, ccl, lisp.exe, or similar names.</p>
+<p>On Unix computers another possible reason would be that the loopback network that provides network connections between two programs in the same computer isnât properly configured.</p>
+<h2 id="how-to-save-data-from-a-broken-.wxmx-file"><span class="header-section-number">5.2</span> How to save data from a broken .wxmx file</h2>
+<p>Internally most modern XML-based formats are ordinary zip files. <em>WxMaxima</em> doesnât turn on compression, so the contents of <code>.wxmx</code> files can be viewed in any text editor.</p>
+<p>If the zip signature at the end of the file is still intact after renaming a broken <code>.wxmx</code> file to <code>.zip</code> most operating systems will provide a way to extract any portion of the information that is stored inside it. This can be done when there is a need of recovering the original image files from a text processor document. If the zip signature isnât intact that does not need to be the end of the world: If <em>wxMaxima</em> during saving detected that something went wrong there will be a <code>.wxmx~</code> file whose contents might help.</p>
+<p>And even if there isnât such a file: The <code>.wxmx</code> file is a container format and the XML portion is stored uncompressed. It it is possible to rename the <code>.wxmx</code> file to a <code>.txt</code> file and to use a text editor to recover the XML portion of the fileâs contents (it starts with <code>&lt;?xml version="1.0" encoding="UTF-8"?&gt;</code> and ends with <code>&lt;/wxMaximaDocument&gt;</code>. Before and after that text you will see some unreadable binary contents in the text editor).</p>
+<p>If a text file containing only these contents (e.g. copy and paste this text into a new file) is saved as a file ending in <code>.xml</code>, <em>wxMaxima</em> will know how to recover the text from the document.</p>

+<h2 id="plotting-only-shows-a-closed-empty-envelope-with-an-error-message"><span class="header-section-number">5.4</span> Plotting only shows a closed empty envelope with an error message</h2>
+<p>This means that <em>wxMaxima</em> could not read the file <em>Maxima</em> that was supposed to instruct <em>Gnuplot</em> to create.</p>
 <p>这个错误的可能原因如下：</p>
 <ul>
-<li>绘图命令是第三方程序包（如 <code>implicit_plot</code>）的一部分，但在尝试绘图之前，没有调用 Maxima 的 <code>load()</code> 命令加载此包。</li>
-<li>Maxima 试图做一些当前版本的 gnuplot 无法理解的事情。此时，在由 Maxima 的变量 <code>maxima_userdir</code> 确定的目录中，以 <code>.gnuplot</code> 结尾的文件包含了 Maxima 给 gnuplot 的指令。在调试问题时，此文件的内容在大多数情况下都是有帮助的。</li>
-<li>Gnuplot 被设置为使用 pngcairo 库以提供抗锯齿功能和更多线条样式，但是在编译时没有开启此项功能支持。解决方案：取消选中设置对话框中的“使用 cairo 终端进行绘图”复选框，并且不要在 Maxima 中将 <code>wxplot_pngcairo</code> 设置为true。</li>
-<li>Gnuplot 没有生成有效的 .png 文件。</li>
+<li>The plotting command is part of a third-party package like <code>implicit_plot</code> but this package was not loaded by _Maxima_âs <code>load()</code> command before trying to plot. - <em>Maxima</em> tried to do something the currently installed version of <em>Gnuplot</em> isnât able to understand. In this case, a file ending in <code>.gnuplot</code> located in the directory, which _Maxima_âs variable <code>maxima_userdir</code> is pointing, contains the instructions from <em>Maxima</em> to <em>Gnuplot</em>. Most of the time, this fileâs contents therefore are helpful when debugging the problem. - Gnuplot was instructed to use the pngCairo library that provides antialiasing and additional line styles, but it was not compiled to support this possibility. Solution: Uncheck the “Use the Cairo terminal for the plot” checkbox in the configuration dialog and donât set <code>wxplot_pngcairo</code> to true from <em>Maxima</em>. - Gnuplot didnât output a valid <code>.png</code> file.</li>

 <p>对单元格的操作和单元格内部的更改均有单独的撤消函数，因此发生这种情况的可能性很低。如果确实是这样，有如下方法可以恢复数据：</p>
 <ul>
-<li>wxMaxima 实际上有两个撤消功能：全局撤消（如果未选择单元格）和单元格内撤消（如果光标在单元格内）。可以尝试使用这两个撤消选项，以查看是否可以恢复内容。</li>
-<li>如果有办法确定 Maxima 分配给该单元格的标签，只需键入此标签，单元格的内容就会重新出现。</li>
-<li>如果忘了单元格的标签，也无需惊慌。在“查看”菜单中，可以勾选显示“历史命令”侧边栏，其中显示了最近使用的所有 Maxima 命令。</li>
-<li>如果以上都没有帮助，可以调用 Maxima 的回放功能：</li>
+<li><em>WxMaxima</em> actually has two undo features: The global undo buffer that is active if no cell is selected and a per-cell undo buffer that is active if the cursor is inside a cell. It is worth trying to use both undo options in order to see if an old value can still be accessed. - If you still have a way to find out what label <em>Maxima</em> has assigned to the cell just type in the cellâs label and its contents will reappear. - If you donât: Donât panic. In the âViewâ menu there is a way to show a history pane that shows all <em>Maxima</em> commands that have been issued recently. - If nothing else helps <em>Maxima</em> contains a replay feature:</li>

-<h2 id="基于-sbcl-的-maxima-耗尽内存"><span class="header-section-number">3.9</span> 基于 SBCL 的 Maxima 耗尽内存</h2>
-<p>默认情况下，Lisp 编译器 SBCL 有一个内存限制，以使得它能在低端计算机上运行。当编译一个大型软件包（如 Lapack）或处理特别大的列表和方程时，该限制值可能太低。为了扩展内存限制，可以向 SBCL 提供命令行参数 <code>--dynamic-space-size</code>，该参数告诉 SBCL 应该使用多少兆字节的内存。32位 Windows 系统版本的 SBCL 最多可使用 999 兆字节，64位 Windows 系统版本的 SBCL 可以被设置为使用更大的内存（例如超过编译 Lapack 所需的约 1280 兆字节）。</p>
-<p>为 Maxima（因此也为 SBCL）提供命令行参数的一种方法是利用 wxMaxima 设置对话框的“额外的 Maxima 参数（Additional parameters for Maxima）”字段。</p>

+<p>One possible reason is that <em>Maxima</em> cannot be found in the location that is set in the âMaximaâ tab of _wxMaxima_âs configuration dialog and therefore wonât run at all. Setting the path to a working <em>Maxima</em> binary should fix this problem.</p>
+<h2 id="maxima-is-forever-calculating-and-not-responding-to-input"><span class="header-section-number">5.8</span> Maxima is forever calculating and not responding to input</h2>
+<p>It is theoretically possible that <em>wxMaxima</em> doesnât realize that <em>Maxima</em> has finished calculating and therefore never gets informed it can send new data to <em>Maxima</em>. If this is the case âTrigger evaluationâ might resynchronize the two programs.</p>
+<h2 id="my-sbcl-based-maxima-runs-out-of-memory"><span class="header-section-number">5.9</span> My SBCL-based <em>Maxima</em> runs out of memory</h2>
+<p>The Lisp compiler SBCL by default comes with a memory limit that allows it to run even on low-end computers. When compiling a big software package like Lapack or dealing with extremely big lists of equations this limit might be too low. In order to extend the limits, SBCL can be provided with the command line parameter <code>--dynamic-space-size</code> that tells SBCL how many megabytes it should reserve. A 32bit Windows-SBCL can reserve up to 999 Megabytes. A 64-bit SBCL version running on Windows can be instructed to use more than the about 1280 Megabytes compiling Lapack needs.</p>
+<p>One way to provide <em>Maxima</em> (and thus SBCL) with command line parameters is the “Additional parameters for Maxima” field of _wxMaxima_âs configuration dialogue.</p>

-<h1 id="常见提问faq"><span class="header-section-number">4</span> 常见提问（FAQ）</h1>
-<h2 id="有没有办法在-latex-页面中显示更多的文字"><span class="header-section-number">4.1</span> 有没有办法在 LaTeX 页面中显示更多的文字？</h2>
-<p>Yes. Use the LaTeX package “geometry” to specify the size of the borders.</p>
+<h1 id="faq"><span class="header-section-number">6</span> FAQ</h1>
+<h2 id="is-there-a-way-to-make-more-text-fit-on-a-latex-page"><span class="header-section-number">6.1</span> Is there a way to make more text fit on a LaTeX page?</h2>
+<p>Yes. Use the <a href="https://ctan.org/pkg/geometry">LaTeX package “geometry”</a> to specify the size of the borders.</p>
 <p>You can add the following line to the LaTeX preamble (for example by using the respective field in the config dialogue (“Export”-&gt;“Additional lines for the TeX preamble”), to set borders of 1cm):</p>
-<div class="sourceCode" id="cb25"><pre class="sourceCode latex"><code class="sourceCode latex"><a class="sourceLine" id="cb25-1" title="1"><span class="bu">\usepackage</span>[left=1cm,right=1cm,top=1cm,bottom=1cm]{<span class="ex">geometry</span>}</a></code></pre></div>
-<h2 id="是否有深色模式"><span class="header-section-number">4.2</span> 是否有深色模式？</h2>
-<p>如果 wxWidgets 版本足够新，那么当系统设置了深色主题时，wxMaxima 将自动处于深色模式。在默认情况下，工作簿本身具有浅色背景。但也可以进行其他配置：利用菜单“查看-&gt;反转工作簿亮度”，可以快速将工作簿在浅色模式和深色模式中转换。</p>
-<h2 id="wxmaxima-有时在启动后的一段时间内无响应"><span class="header-section-number">4.3</span> wxMaxima 有时在启动后的一段时间内无响应</h2>
-<p>wxMaxima 将一些大型任务（如解析 Maxima 的超过 1000 页的手册）委托给后台任务，而这些任务通常不会被执行。然而，当需要执行这样一个任务时，可能需要等待几秒钟才能继续工作。</p>
+<p><code>latex \usepackage[left=1cm,right=1cm,top=1cm,bottom=1cm]{geometry}</code></p>
+<h2 id="is-there-a-dark-mode"><span class="header-section-number">6.2</span> Is there a dark mode?</h2>
+<p>If wxWidgets is new enough, <em>wxMaxima</em> will automatically be in dark mode if the rest of the operating system is. The worksheet itself is by default equipped with a bright background. But it can be configured otherwise. Alternatively, there is a <code>View/Invert worksheet brightness</code> menu entry that allows to quickly convert the worksheet from dark to bright and vice versa.</p>
+<h2 id="wxmaxima-sometimes-hangs-for-several-seconds-once-in-the-first-minute"><span class="header-section-number">6.3</span> <em>WxMaxima</em> sometimes hangs for several seconds once in the first minute</h2>
+<p><em>WxMaxima</em> delegates some big tasks like parsing _Maxima_âs &gt;1000-page-manual to background tasks, which normally goes totally unnoticed. At the moment the result of such a task is needed, though, it is possible that <em>wxMaxima</em> needs to wait a couple of seconds before it can continue its work.</p>
+<h2 id="especially-when-testing-new-locale-settings-a-message-box-locale-âxx_yyâ-can-not-be-set-occurs"><span class="header-section-number">6.4</span> Especially when testing new locale settings, a message box “locale âxx_YYâ can not be set” occurs</h2>
+<figure>
+<img src="./locale-warning.png" alt="Locale warning" id="img_locale_warning" /><figcaption>Locale warning</figcaption>
+</figure>
+<p>(The same problem can occur with other applications too). The translations seem okay after you click on âOKâ. WxMaxima does not only use its own translations but the translations of the wxWidgets framework too.</p>
+<p>These locales maybe not present in the system. On Ubuntu/Debian systems they can be generated using: <code>dpkg-reconfigure locales</code></p>
+<h2 id="how-can-i-use-symbols-for-real-numbers-natural-numbers-â-â-etc."><span class="header-section-number">6.5</span> How can I use symbols for real numbers, natural numbers (â, â), etc.?</h2>
+<p>You can find these symbols in the Unicode sidebar (search for âdouble-struck capitalâ). But the selected font must also support these symbols. If they do not display properly, select another font.</p>
+<h2 id="how-can-a-maxima-script-determine-if-it-is-running-under-wxmaxima-or"><span class="header-section-number">6.6</span> How can a Maxima script determine, if it is running under wxMaxima or</h2>
+<p>command line Maxima?</p>
+<p>If wxMaxima is used, the Maxima variable <code>maxima_frontend</code> is set to <code>wxmaxima</code>. The Maxima variable <code>maxima_frontend_version</code> contains the wxMaxima version in this case.</p>
+<p>If no frontend is used (you are using command line Maxima), these variables are <code>false</code>.</p>
 <hr />
-<h1 id="命令行参数"><span class="header-section-number">5</span> 命令行参数</h1>
-<p>在大多数操作系统中，wxMaxima 都有比运行命令行更简单的启动方式，所以用到命令行参数的可能性很小。不过，wxMaxima 仍然提供了一些命令行选项。</p>
+<h1 id="command-line-arguments"><span class="header-section-number">7</span> Command-line arguments</h1>
+<p>Usually you can start programs with a graphical user interface just by clicking on a desktop icon or desktop menu entry. WxMaxima - if started from the command line - still provides some command-line switches, though.</p>
 <ul>
 <li><code>-v</code> 或 <code>--version</code>：输出版本信息。</li>
 <li><code>-h</code> 或 <code>--help</code>: 输出简短的帮助文本。</li>
-<li><code>-o</code> 或 <code>--open=&lt;str&gt;</code>：打开作为此命令行参数的文件名。</li>
+<li><code>-o</code> or <code>--open=&lt;str&gt;</code>: Open the filename given as an argument to this command-line switch</li>
 <li><code>-e</code> 或 <code>--eval</code>：打开文件后对公式单元格求值。</li>
-<li><code>-b</code> 或 <code>--batch</code>：如果用命令行打开一个文件，则计算该文件中的所有单元格，然后保存文件。例如，如果文件中描述的会话使 Maxima 生成输出文件，则这一参数会很有用。如果 wxMaxima 检测到 Maxima 输出了错误信息，则批处理将停止；如果检测到 Maxima 有疑问，则批处理将暂停。Maxima 的计算过程有一定的交互性，因此无法保证完全无交互的批处理。</li>
+<li><code>-b</code> or <code>--batch</code>: If the command-line opens a file all cells in this file are evaluated and the file is saved afterward. This is for example useful if the session described in the file makes <em>Maxima</em> generate output files. Batch-processing will be stopped if <em>wxMaxima</em> detects that <em>Maxima</em> has output an error and will pause if <em>Maxima</em> has a question: Mathematics is somewhat interactive by nature so a completely interaction-free batch processing cannot always be guaranteed.</li>
 <li><code>--logtostderr</code>: Log all “debug messages” sidebar messages to stderr, too.</li>
 <li><code>--pipe</code>: Pipe messages from Maxima to stdout.</li>
 <li><code>--exit-on-error</code>: Close the program on any maxima error.</li>
-<li><code>-f</code> or <code>--ini=&lt;str&gt;</code>: Use the init file that was given as argument to this command-line switch</li>
+<li><code>-f</code> or <code>--ini=&lt;str&gt;</code>: Use the init file that was given as an argument to this command-line switch</li>
 <li><code>-u</code>, <code>--use-version=&lt;str&gt;</code>: Use maxima version <code>&lt;str&gt;</code>.</li>
 <li><code>-l</code>, <code>--lisp=&lt;str&gt;</code>: Use a Maxima compiled with Lisp compiler <code>&lt;str&gt;</code>.</li>
 <li><code>-X</code>, <code>--extra-args=&lt;str&gt;</code>: Allows to specify extra Maxima arguments</li>
-<li><code>-m</code> or <code>--maxima=&lt;str&gt;</code>: allows to specify the location of the <em>maxima</em> binary</li>
+<li><code>-m</code> or <code>--maxima=&lt;str&gt;</code>: allows specifying the location of the <em>maxima</em> binary</li>
 <li><code>--enableipc</code>: Lets Maxima control wxMaxima via interprocess communications. Use this option with care.</li>
+<li><code>--wxmathml-lisp=&lt;str&gt;</code>: Location of wxMathML.lisp (if not the built-in should be used, mainly for developers).</li>
 </ul>
-<p>一些操作系统可能在命令行选项前面使用连字符（-，dash），而不是减号。</p>
+<p>Instead of a minus, some operating systems might use a dash in front of the command-line switches.</p>

+<h1 id="about-the-program-contributing-to-wxmaxima"><span class="header-section-number">8</span> About the program, contributing to wxMaxima</h1>
+<p>wxMaxima is mainly developed using the programming language C++ using the <a href="https://www.wxwidgets.org">wxWidgets framework</a>, as build system we use <a href="https://www.cmake.org">CMake</a>, a small part is written in Lisp. You can contribute to wxMaxima, join the wxMaxima project at <a href="https://github.com/wxMaxima-developers/wxmaxima" class="uri">https://github.com/wxMaxima-developers/wxmaxima</a>, if you have knowledge of these programming languages and want to help and contribute to the open source project wxMaxima.</p>
+<p>But not only programmers are necessary! You can also contribute to wxMaxima, if you help to improve the documentation, find and report bugs (and maybe bugfixes), suggest new features, help to translate wxMaxima or the manual to your language (read the README.md in the <a href="https://github.com/wxMaxima-developers/wxmaxima/tree/main/locales">locale subdirectory</a> how wxMaxima and the manual can be translated).</p>
+<p>Or answer questions of other users in the discussion forum.</p>
+<p>The source code of wxMaxima is documented using Doxygen <a href="https://wxmaxima-developers.github.io/wxmaxima/Doxygen-documentation/">here</a>.</p>
+<p>The program is nearly self-contained, so except for system libraries (and the wxWidgets library), no external dependencies (like graphic files or the Lisp part (the <code>wxmathML.lisp</code>-file) is needed, these files are included in the executable.</p>
+<p>If you are a developer, you might want to try out a modified <code>wxmathML.lisp</code>-file without recompiling everything, one can use the command line option <code>--wxmathml-lisp=&lt;str&gt;</code> to use another Lisp file, not the included one.</p>
