TW5 - An environment with LaTeX and Markdown?

[radu....@gmail.com]

I started using tiddlywiki about one week ago, on the third attempt. The thing that made it viable for me was the TexZilla plugin. It works great, providing most notably the "aligned" environment which is missing in KaTeX.

This makes TW5 almost perfect as a math notebook. What is missing is Markdown. Besides making the notes look much better, having them written in markdown syntax would make sharing one's work on (virtually all) online forums seamless.
Unfortunately, the Markdown plugin doesn't work together with the LaTeX plugin (one has to designate the content type as text/x-markdown and as a consequence the LaTeX rendering is inactivated).

Are there any solutions of having markdown and LaTeX rendering functional at the same time?

Thank you

Hi Radu

Not at the moment, I'm afraid. It would need some hacking to the Markdown parser to make it parse the $$ markers. The Markdown.js parser that we use is not particularly actively developed:

https://github.com/evilstreak/markdown-js

We may be better off using a new alternative such as:

https://github.com/chjj/marked

It seems to be superior in a few ways (eg inclusion of "smarty pants" quote handling).

Best wishes

Jeremy.

 

Thank you

Thank you Jeremy for the quick reply.
I'm probably just showing my ignorance here, but is there any chance this would work if the order in which the parsers act would be swapped? If the TeXZilla plugin does the correct job for the '$$' delimited blocks (i.e. produces html output for them while ignoring the rest of the text), is it possible that the Markdown plugin would just work if applied after that?

Thanks again
Radu

Sadly not. Parsers in TW5 convert a stream of text into a parse tree which is a hierarchical structure that represents the logical structure of the text. The parse tree can't be fed back into another parser because the parser will be expecting text.

Jeremy,

In https://github.com/llpamies/texdown there is a simple tiddlywiki plugin that combines Marked and TeXZilla engines as Radu was requesting. The fancy options available in Marked are not enabled, but it is easy to add, even configure it from the  tiddly wiki GUI.

Is there any option to get that into the main tree?

Best,
Lluis

Hi

Perhaps it would be advantageous to switch to a multi-markdown plugin: http://fletcherpenney.net/multimarkdown/features/

Or it may be possible to create an EpicEditor plugin -- this would allow a choice of parsers (Marked comes standard): http://oscargodson.github.io/EpicEditor/

Great, well done. I think this would be useful for the core, the only issue is that you've implemented it as a parser module where I'd have expected it to be a widget that works along the same lines as the current KaTeX plugin. Was there a particular reason that you took this approach?

Assuming we resolve that, there are a few other things to be done:

* You'll need to sign the Contributors License Agreement, as described in contributing.md in the TW5 repo

* Add a readme to the plugin

* Create a pull request that adds the plugin to `plugins/tiddlywiki`

* It would be useful to add a "LaTeX" tiddler to the tw5.com edition that compares the capabilities of KaTeX and TeXZilla to help people choose which is best for them

Best wishes

Jeremy.

I've tried a similar approach in https://github.com/padawanphysicist/tw5-mathdown, but using markdown-it as the Markdown parser. Do you think it would be possible to integrate the plugin to use MathJax as the LaTeX renderer in browsers where MathML is not available?

I think a parser is the right way to go for handling Markdown. The advantage of packaging the math support as a widget is just so that it can be re-used with different parsers.

The trouble with MathJax, as you've probably discovered, is that it's entirely DOM-based, and it wouldn't be possible to, say, use it to generate static math markup on the server. But you could certainly still use it within those limitations,

Sorry for the necrobump, but does anyone know if anyone figured out a way to parse LaTeX in markdown?

Another bump!
