Resulting where the nested math \mathcal M$ is not correctly rendered.

While

#import "@preview/mitex:0.2.1": *
#set math.equation(numbering: "(1)", supplement: [#text(blue)[*Eq.*]])

#mitext(`
    \begin{align}
      \text{Stokes formula for Manifold}~$\mathcal M$\quad \int_{\mathcal M}\mathrm{d}\omega&=\int_{\partial\mathcal M}\omega

is OK

Hi, after several days trial of mitex, I found several annoying inconsistencies, even for standard math notation:

1. In math, we use square bracket [ and parenthesis ( to represent the close and open set. But when I try to convert my notes including something like $[0,1,\cdots, N_s)$ blablabla, I got serious parse error (collapse to one line)

It seems because the parser found some unclosed/unpaired bracket. If so, that is really stupid to me (we should be free to use any symbol in math mode).

2. The vertical line in latex is somewhat parse to wrong symbol, for example, Bloch states$|\boldsymbol k\rangle$ is wrongly parsed by mitex: I got extra spaces between k and the vertical line. But if I try to make it converting from $\ket{\boldsymbol k}$ by explicitly telling mitex what the composite symbol is (here is the ket state), then the conversion is OK.

In latex at least $|\boldsymbol k\rangle$ and $\ket{\boldsymbol k}$ looks the same, without knowing the meaning for the composite symbol |...\rangle, and there are indeed some situation when $\bra{...}$ or $\ket{...}$ or $\braket{...}$ cannot handle, that is why most people still control the size of vertical line | and the size of angle bracket \langle and \rangle by hand.

If I get it correctly, for the time being, mitex only works as a WASM module and thus only works on the typst web app, but not for the CLI.

It would be better to provide a CLI program that runs like:

mitex -i foo.tex -o foo.typ

Then we can deal with the typst source with typst-cli.

Another benefit of this is that we can easily build a testset with a bunch of TeX sources, which will largely assure the quality and stability of mitex.

Hi, I found that that both \mathbf . and \mathbf{...} cannot be correctly rendered in desired form as in LaTeX (bold AND regular). For example,

#import "@preview/mitex:0.2.2": *

#mitext(`Reciprocal vector is $\mathbf G$ or $\mathbf{G}$`)

gives

But in LaTeX, it should be

NOTE: \bm (as well as \boldsymbol(please also add support for this command)) behaves different from \mathbf!

And here is one more tricky thing:

See https://tex.stackexchange.com/questions/294561/using-textbf-vs-mathbf-in-math-mode. Precisely, \mathbf{...} and \textbf{...} are different in LaTeX, in that \mathbf{...} will remove ALL blank spaces within its arguments. So probably a more correct rendering is to parse, for example, for the LaTeX code:

$\sum_{i\in\mathcal I}\mathbf{Op With Space}=\text{blablabla}$

as the Typst code:

$ sum_(i in cal(I))bold(#"Op With Spaces".replace(" ", ""))="blablabla" $ 

I think this clearly demonstrate how to fix the \mathbf rendering problem : )

Thanks for your help!

I'd like your opinions on these changes, specifically, was any of this the unsafe code used for performance reasons and are the safe replacements too slow?

I have refactored the parser and added some tests for formulas.

During testing, I find a bug:

https://github.com/mitex-rs/mitex/blob/b85675ab1eba8774894948091432765fb433f1cc/crates/mitex/src/lib.rs#L1151-L1156

And two optional semantic errors to handle:

Not too sure on some of the organization, particularly treating \( and \[ as dollars syntactically.

#import "packages/mitex/mitex.typ": *

= Converted

#let test_text = "
  \\(1 + 2\\)
  \\[1 + 2\\]
"

#raw(mitex-convert(mode: "text", test_text))
= Rendered

#eval(
  mitex-convert(mode: "text", test_text), mode: "markup", scope: mitex-scope,
)

gives

Closes #124

Is it possible to load an image in a iftypst block?

I've been able to use typst.ts with mapShadow in the browser to render images. However, when I try to put this image in a iftypst block, I get a "failed to load file (access denied)", trace: [Call(Some("mimath"))], hints: ["cannot read file outside of project root" error.

It seems to me that the web demo is able to import both a bibliography and another template file. However, I cannot figure out where inpackages/mitex-web/src this virtual file system is handled. It appears that there is a VFS for the sidebar directory view, but I cannot tell how this integrates with mitex. Is there some documentation on this?

I am genuinely impressed with potential of this project and excited about the possibilities it offers. However, I've encountered a bit of a roadblock. As a new user, I'm unsure about the installation process, as the current README file doesn't include an installation section. This has made it challenging for me to get started with the project.

Could you please consider adding an installation guide to the README?

version: 0.2.4: problem:

#mi("\langle{w_1}\rangle")
#mitex(`\langle{w_1}\rangle`)

is different, and #mi fail to generate \rangle.

by the way, could anyone tell me that how to present $\langle \rangle$ in typst?

When using explicit equation environments (such as equation or aligned), the spacing around the equation changes when the equation has multiple lines. This is not the case when just using $$ ... $$. For example

Lorem ipsum dolor sit amet consetetur sadipscing elitr sed diam nonumy

% Left side in image (this is shifted upwards)
\begin{aligned}
  a^2 + b^2 = c^2 \\
  a^2 + b^2 = c^2
\end{aligned}

Lorem ipsum dolor sit amet consetetur sadipscing elitr sed diam nonumy

% Right side in image (this is what I would expect)
$$ 
  a^2 + b^2 = c^2 \\
  a^2 + b^2 = c^2
$$

Lorem ipsum dolor sit amet consetetur sadipscing elitr sed diam nonumy

The new version of typst has fixed the weird spacing in left...right pairs, see Fixed weak spacing in lr groups in https://github.com/typst/typst/releases/, for example the bra-ket symbol, as well as \mid in quantum mechanics.

Please update the conversion to correct typst command for correct rendering.

At https://mitex-rs.github.io/mitex/tools/underleaf.html, \[ ... \] (which is preferable to $$ ... $$, and used by many) is not parsed correctly. I put two \ so that it renders correctly but in LateX there is only one. See https://tex.stackexchange.com/questions/503/why-is-preferable-to
