MathJax VS KeenWrite

Developer tools point to MathJax https://www.mathjax.org/. If you disable javascript you can see some LaTex.

It is something we could add, but it is not planned in the near future. We also have requests for adding math notation (like https://www.mathjax.org/), and that could be a more general solution.

I don't know what Obsidian is, but if it's requiring old TeX math mode toggles (the double dollar sign), then it might not actually be using LaTeX underneath. Many tools that provide LaTeX-style syntax for equations are actually using something like MathJaX, BlahTex, or some custom system by which to translate LaTeX-like syntax into their own equation rendering. This often means you only get a pre-defined subset of what's possible with LaTeX (and the results are never quite faithful to how LaTeX would typeset them).

This will depend heavily on where you're asking the question, e.g. stackexchange has built in mathjax to render it. I'm going to assume you're intending to ask here (because that would make sense), in which case check out the bottom of the sidebar.

From the screenshot, Obsidian looks like a typical Markdown editor that supports some LaTeX math syntax, probably rendered with something like Mathjax. On the other hand, Xournalapp seems to actually use LaTeX, even allowing you to use LaTeX packages like graphicx, tikz, etc.

KeenWrite is my free, open-source, cross-platform desktop Markdown editor that can produce beautifully typeset PDFs. I started working on it years ago to help write a novel that has a complex timeline and I couldn't find a text editor that would allow me to integrate a character sheet with the story itself.

Here's what I mean by using variables directly:

CommonMark doesn't propose a standard for bibliographic references. Would anyone find the editor more appealing if it had cross-references and citations?

My cross-platform desktop text editor, KeenWrite, allows users to define variables in an external YAML file. The editor calls out to Kroki[1] to convert text-based diagrams to SVG. The diagrams can reference variables and are rendered using EchoSVG[2].

KeenWrite[3] can produce PDF documentation from Markdown documents that has PlantUML diagrams with elements stored in an external, machine-readable file. Here are screenshots showing variables on the left, diagram text in the middle, and a real-time render on the right:

KeenWrite supports all diagrams offered by Kroki, which includes "diagram-plantuml".

Although not interactive, I've created a video series that shows advanced usage of Markdown. Namely R, external variables, diagrams, math, annotations, and a different approach to metadata:

Tutorial 4 shows basic Markdown:

The top-right of each video shows keyboard and mouse clicks to help follow along.[1] My desktop text editor, KeenWrite[2], is used in the tutorials.

My template script provides a way to make user-friendly shell scripts. In a script that uses the template, you define the dependencies and their sources:

I didn't create the fork, nor am I affiliated with the project. I use it in my text editor, KeenWrite to rasterize SVG.

KeenWrite Themes[1] are instructions that tell ConTeXt how to typeset XHTML documents (content) into PDF files (presentation). I made a tutorial that shows how my FOSS desktop text editor, KeenWrite[3], allows users to write in Markdown to typeset a document against a particular theme.

Before it can be used for scientific papers, it needs cross-references, which, unfortunately, aren't part of the CommonMark specification.

I posit that the vast majority of LaTeX users don't grok how to separate content from presentation. When I asked a question on TeX.SE about how to adjust the line spacing between enumerated items (spanning a couple dozen enumerated lists), the vast majority of people voted for the answer of using `\itemsep0em` to tweak each list ... individually.[4] The correct answer, IMO, is to fix the problem globally, and not waste time tweaking individual lists.
