Latex output

[s5bug]

I'd love to use Diagon in a project I want to make, similar to org-mode but with more modern syntax, output, and tooling. I love how Diagon parses expressions, and so I was wondering how easy it is to add more backends because I don't want to reinvent the wheel. I'm personally looking for:

• ASCII (already implemented)
• utf-8 (already implemented)
• KaTeX/HTML
• LaTeX

I've used the latter two a lot, so I'm pretty comfortable with them; if it's not too hard and isn't against the scope of the project I'd love to try and implement them.

We have several "generator"

• Mathematic Expression
• Sequence Diagram
• Tree
• Frame
• Table
• Planar graph

And the generators have "options", the one in Mathematic Expression are:

- ASCII-only [x]
- Math symbols [x]

I can replace the first one by:

style: [
- unicode
- ascii
- latex
]

I can work on it this weekend, starting with the "Mathematic Expression" generator.

Could you describe a bit more your project? Is this a web based application or are you using the command line application?

I have made some experiment using vim + diagon here: https://youtube.com/watch?v=WTnMft_wvZU

[s5bug]

I would probably bundle the command line application in the document rendering program, or write my thing in C++ and build it with.

I'm tired of org-mode's lack of:

• Math expressions in the text-based outputs (ascii, utf8)
• Bibliography support
• Footnote support
• Graph/Tree support

So I've been wanting to write my own thing, and I stumbled across Diagon and the way it parses expressions and has existing utf8 and ascii options makes it a good fit for what I want to do.

I added a "Latex" mode for the mathematic generator. I updated the website: https:/arthursonzogni.com/Diagon

(you will likely have to refresh and/or clear the website disk cache to get the new version)

Does it work the way you expected?

[s5bug]

Sorry for the late response.

It almost works the way I expect. I'm not able to actually test the LaTeX right now, but a few things that worry me:

• \displaystyle vs inline LaTeX, the former should but \limits on Sums, Integrals, etc I believe (however I am not sure).
• f(x) = turns into \f{x} =, I'm fairly certain it should be just f\left(x\right) =
• (expr), even when parentheses are needed, turns into {latexexpr}, instead of \left(latexexpr\right)
• \cdot for multiplication vs \times
• \ldots for ellipsis
• \alpha{}, \Alpha{} instead of the literal symbols

[ArthurSonzogni]

Thanks for this list! I will submit fixes one by one.

Ideally, I should find a way to build a vizualizer that will build images from latex.

[s5bug]

I forgot to mention, special functions, like log, sin, cos, etc, that should be rendered like this and not like this have a backslash before them. \sin\left(3 + x\right).

As for the visualizer, unless you mean Diagon parsing LaTeX itself, I would recommend KaTeX output at least for the website.

[ArthurSonzogni]

I am going to use MathJax to renderer the latex formula. I am starting to get really nice results.

[s5bug]

KaTeX can statically compile LaTeX into HTML without the need for client-side JS and also doesn't push its own right-click menu, if that's an option.

[ArthurSonzogni]

Katex claims to be faster / smaller, so I will use Katex. Thanks for the suggestion! This will be done likely at the very end of this week.

[ArthurSonzogni]

I updated the website. This should now render the latex formula using katex.

From your list of fixes to do:

• [X] \displaystyle vs inline LaTeX, the former should but \limits on Sums, Integrals, etc I believe (however I am not sure).
• [X] f(x) = turns into \f{x} =, I'm fairly certain it should be just f\left(x\right) =
• [X] (expr), even when parentheses are needed, turns into {latexexpr}, instead of \left(latexexpr\right)
• [X] \cdot for multiplication vs \times
• [ ] \ldots for ellipsis
• [X] \alpha{}, \Alpha{} instead of the literal symbols
