POD Parser | ||
in C++ | ||
|
||
This is a parser for Perl's POD markup language (see | ||
<https://perldoc.perl.org/perlpodspec.html>), entirely written in C++. | ||
|
||
This project is developed mainly for use for the generation of the | ||
scripting API docs of The Secret Chronicles of Dr. M. (TSC; see | ||
https://secretchronicles.org), but has been extracted into its own | ||
project as it turned out to be a little more than a simple parser for | ||
simple markup language. As a result of this history, the parser | ||
is written to be used in the context of HTML generation. If you need | ||
to generate something other than HTML, take a look at the ToHTML() | ||
methods of the various PodNode subclasses and implement similar | ||
ToYourOutput() methods yourself. | ||
|
||
- How to use - | ||
|
||
The C++ POD parser is written in C++11 and has no external | ||
dependencies. It is recommended to insert the two files directly into | ||
your project, but a simple Makefile is provided for building it as a | ||
library so it is possible to run: | ||
|
||
$ make | ||
|
||
This is going to create a static and a shared library named | ||
libpod-cpp.a and libpod-cpp.so, respectively. | ||
|
||
After building the C++ POD parser, include the header: | ||
|
||
#include "pod.hpp" | ||
|
||
Write a function that tells the parser how a file name looks like for | ||
any given class or module name: | ||
|
||
std::string filename_cb(std::string classmodname) | ||
{ | ||
return classmodname + ".html"; | ||
} | ||
|
||
Write another function that tells the parser how an HTML A tag's @name | ||
tag looks like if given a method name and the information about | ||
whether it's a class or module method: | ||
|
||
std::string methodname_cb(bool cmethod, std::string methodname) | ||
{ | ||
return cmethod ? methodname + "-cm" : methodname + "-im"; | ||
} | ||
|
||
Then, instanciate the parser with the string to parse and start | ||
the parsing process: | ||
|
||
PodParser parser("=head1 The title\n\nLorem ipsum dolor sit amet\n", | ||
filename_cb, methodname_cb); | ||
parser.parse(); | ||
|
||
It is then possible to retrieve the list of parsed tokens (which are | ||
all subclasses of PodNode) and call the virtual PodNode::ToHTML() | ||
method on all of them in order to transform the tokens into HTML: | ||
|
||
const std::vector<PodNode*> tokens = parser.GetTokens(); | ||
for(const PodNode* p_token: tokens) { | ||
std::cout << p_token->ToHTML(); | ||
} | ||
|
||
If this is the entire processing required, a convenience function | ||
Pod::FormatHTML() exists that takes the token list as returned | ||
by PodParser::GetTokens() and does the exact same thing like | ||
the snippet above. | ||
|
||
std::cout << Pod::FormatHTML(parser.GetTokens()); | ||
|
||
Either way, this is going to dump the entire HTML for all the tokens | ||
to the standard output. Note there is no need to manually insert | ||
newlines between tokens. This is taken care of where necessary. | ||
|
||
- Limitations and Extensions - | ||
|
||
This parser is not entirely compliant with the POD specification. The | ||
most significant diversion is probably that it is not valid to use any | ||
kind of formatting code inside the link target of the L<> formatting | ||
code, especially not the E<> code. | ||
|
||
That being said, the parser is good enough to process TSC's scripting | ||
API documentation, which is its primary purpose. If not given too | ||
complicated markup, there should be no problem. | ||
|
||
TSC's scripting API is an object-oriented Ruby API. Therefore, the POD | ||
markup has been slightly extended to support typical Ruby API methods, | ||
which manifests itself in a modified behaviour of the L<> code. As | ||
with ordinary POD, an L<> formatting code without a bar (|) means an | ||
internal link to another object in the same documentation. Format | ||
L<Object/Section> can also be used as normal. However, additionally, | ||
it is possible to use an L<> code with one of the following two forms: | ||
|
||
1. L<Object#imethod> creates an internal link to the instance method | ||
`imethod' of the class or module `Object'. | ||
2. L<Object::cmethod> creates an internal link to the class or module | ||
method `cmethod' of the class or module `Object'. | ||
|
||
These two extensions can also be used with explicit link text, e.g.: | ||
|
||
L<explicit link text|Object#imethod> | ||
|
||
Problems with obscure markup may be reported, but depending on the | ||
complexity of the problem might not be fixed if there is no chance | ||
that this markup occurs in TSC's scripting API documentation. | ||
