There is *currently* no support for parsing RST-formatted content.
However, since everything in TiddlyWiki is based on HTML/CSS/Javascript, it should be *possible* to create such a plugin.
TiddlyWiki already handles rendering of HTML content, so it shouldn't be *too* hard to take a tiddler
containing RST content with type="text/x-rst" (the "unofficial official" MIME type for RST) and pass it
through a plugin library such as the above "rst2html", and then render the resulting HTML output.
However, this is not trivial, and would require a TiddlyWiki technical expert to implement the various
parts and glue it all together. Unfortunately, while I can envision the possibility, I personally have
*no* experience in implementing alternative parser plugins for the TWCore, so this would have to
be a project for one of the other TiddlyWiki "wizards" out there.
Note that, even if this was done, there would still be some issues with the results. For example:
* would it be possible to create links to other tiddlers from within RST-formatted content?
* similarly, could TW transclusions be used?
* and, what about TW macro definitions (either TWCore or custom-written macros)?
I suspect that, with some additional effort, at least some of the above issues could be addressed
once the basic parsing and rendering of RST-to-HTML is working.
All in all, this seems like an interesting project for someone with the right skill set, but it would
probably be a significant investment of time and effort, so there would need to be a strong
motivation for doing the work and maintaining the results. Since you are the first person
to ask about support for RST-formatted content, I suspect that the demand for such functionality
is currently limited in the TiddlyVerse.
