hashtags wikirule breaks stylesheets

[tobibeer]

I was about to write a wikirule parser that will do something with a #hashtag, or so I thought.

Turns out, this appears to break about every single stylesheet tiddler or palette being loaded by TiddlyWiki, except those of type text/css, I presume.

How can I possibly cater for a #hashtag wikirule and make sure it never gets applied for tiddlers matching a given filter, e.g. never those tagged $:/tags/Stylesheet, and never to palettes?

Furthermore, I don't see any capability to do:

\rules allow hashtag

...to allow the rule for a given context only, e.g. things within the PageTemplate. Actually, I am not quite sure where stylesheets get loaded at all.

Let's say a Stylesheet retrieves a color from a palette:

{{SomePalette##some-color}}

...or uses the color macro to achieve the same.

How can I ensure it will never use the hashtag wikirule to parse the contents so that the result is never going to be hash-tagified?

Atm I feel like it just isn't possible to separate content (hashtags) from presentation (styles) that way.

There are some discussions, to improve the tw tiddler "type" mechanism with the possibility to enable additional or even completely different wikitext vocabularies. see issue #345: "Introduce vocabulary parameter to wikitext content type"

@buggyj also created a working prototype: http://tw5vocab.tiddlyspot.com/ ... So having a closer look at this implementation imo would also solve some other long standing issues.

Hi @pmario, as for #345 I definitely do not want (users) to have to be specific about the vocab. So, I'd want a different global vocabulary applied by the core to different contexts, e.g. one for "everything stylesheet / theme" and another for "content"... whichever way those two get to be separated.

It feels like all core themes, stylesheets, palettes need to explicitly define:

\rules only this and that

...so as to have more flexibilities with respect to the rules allowed in actual content without breaking a theme or stylesheet.

@Jermolene => Create new issue?

@Jermolene, I am starting to think that whenever the text of a tiddler tagged $:/tags/Stylesheet or an index of a tiddler tagged $:/tags/Palette is parsed and transcluded, the result must never contain html ...since, clearly, we are operating on what is expected to be valid css syntax in terms of output.

I don't really know, but it feels like this requires wiki-rules to operate in either a dom-mode or a text-mode, whereas the latter must never yield widgets that create html elements in the dom.

In other words, the parser identifying a wikirule handling something like a #hashtag — a pattern which color entries in the palette may as well match, e.g. #ABC, #BBC, #cab or just #1122ff — may normally render a widget. However, when in text mode, it will only ever retrieve a text-node at best.

Likely not of practical use but anyway FYI: There are a few variants of the hashtag, or number sign as the characters "real" name apparently is, 井 ♯ ⌗ ⋕ # - see wikipedia
