How to add syntax coloring for new languages?

What I’m trying to do

I would like Mathematica code blocks to format nicely like they do for other languages with syntax coloring.

Consider in the following two code blocks:

def fun():
    x = 1
f[x0_] := Module[{x = x0},
  While[x > 0, x = Log[x]]; x

The python code looks good, but the wolfram code looks like verbatim:

What I’ve tried

Mathematica (aka wolfram language) is less popular but is still supported in many editors like Sublime e.g. WolframLanguage - Packages - Package Control)

I managed to find a project that formats wolfram code with css/html here: GitHub - halirutan/Mathematica-Source-Highlighting: Highlighting of Mathematica code for Mathematica.stackexchange

I’ve tried to hook it up, but I don’t know how to do this properly, any guidance here would be much appreciated!

@eb1ack I was just wanting to ask this question! Are there any plugin developers here that might be able to help? #get-help

It looks like @deathau’s plugin CM Editor Syntax Highlighting has Mathematica as a parser language. Give it a try?

@valentine.195 Thanks! That solves it for edit mode, but what about preview mode too?

I think syntax coloring in preview is provided by PrismJS. I don’t see Mathmatica in their list of supported languages:

I don’t think there’s anything the Obsidian devs can do about that. I think you’d have to open an issue with the PrismJS team:


Prism just recently added support for mathematica: Next features to add for wolfram language · Discussion #2926 · PrismJS/prism · GitHub

But wolfram code blocks still don’t work in obsidian!

@craig Can you ping obsidian devs to rebuild the app with the latest prism?

Hi @eb1ack , sorry, I’m just a fellow user. I don’t have any pull with the Obsidian devs.

Maybe you can ping Licat or Silver in the Discord server (Community - Obsidian)

Thanks for the tip, I’ll try to contact them there!

This is a perfect example here of how things work in software development so that many can benefit:

  • Know which (so called “upstream”) third-party code is used. I wish Obsidian would have an official list somewhere.

  • Nail down a bug or feature request to one of these “building blocks”.

  • Make a bug report, feature request or even a pull request there and see that it gets fixed or implemented.

  • Ask the “downstream” software using that code/library to include the new version of the “upstream” package.

Working like this has the greatest benefits for all:

  • Both upstream and downstream developers can focus on their part of the code.
  • Other users and projects will benefit, because upstream packages and libraries tend to get used by many.

Writing custom workarounds and patches at the “end of the chain”

  • is counterproductive
  • will break eventually when upstream code is updated
  • unnecessarily binds resources and time that could better be used on the actual downstream project

Just my 2¢.


I have this problem too.

PrismJS claims that you can use ‘wolfram’, ‘mathematica’, ‘wl’ or ‘nb’ to reference Mathematica code, but in Obsidian no syntax highlighting occurs.

Yes indeed, but the Obsidian devs need to update the Obsidian app (and use the updated prism library).
