Typst Support

[nathanrboyer]

There seems to be significant enthusiasm behind a new typesetting system called Typst to replace LaTeX. I would like to be able to use this package with it.

A Latexify.jl equivalent Typstry.jl already exists, so hopefully you can just swap out the backend?

Probably a big ask, but I leave it anyway for your consideration. Thanks.

All of the code is heavily dependent upon the Latexify.jl package, so I don't think this is doable without a Typst equivalent of latexify.jl. It looks like Typstry is more so the equivalent to LaTeXStrings.jl right?

However, I have used the typst option for rendering in quarto and the handcalcs equations render out. Have you tried that?

@jakobjpeters can you comment on feasibility here?

It has similar goals to both LaTeXStrings.jl and Latexify.jl. Formatting Julia values is done by defining methods of show_typst(::IO, ::T), which is called by show(::IO, ::MIME"text/typst", ::T) and integrates with TypstString(::T). However, LaTeXStrings.jl implements more formatting rules than Typstry.jl. The big one here is for Expr, which is arguably Latexify.jl's biggest feature.

So after Typstry.jl implements show_typst(::IO, ::Expr), I do think it would be feasible to support both as a back-end but would require some refactoring in Handcalcs.jl to split them. I'm still considering what approach I want to take with this feature, but it's in-progress. An example may look something like:

a = 2

@typst($a * x)
    == TypstString(:(2 * x))
    == TypstString(TypstFunction(*, 2, :x))
    == typst"$2x$"

I tried typst for the first time last night, and it is pretty amazing. I guess time will tell how good integration we can get in Julia with typst, but yeah I can try and get it integrated once features are closer to Latexify!
