Implements cetz diagrams #37

[benabel]

This is a basic implementation using typst to compile cetz code to svg, png or pdf.

[benabel]

The filter works with pandoc, but recent changes in the filter makes it fail with quarto see #39.

[tarleb]

Looks great, thanks! The only request I have is about something minor in the docs 😅

[tarleb]

The package itself seems to use the capitalization CeTZ.

[benabel]

OK, done.

[tarleb]

Oh, and running the test during CI would be good, too. There seems to be a typst package available on Alpine, so using pandoc/minimal:latest-alpine as base image should work well. See .github/workflows/ci.yaml.

[benabel]

I've added the CI action using quarto image to use their built-in typst program.

[tarleb]

oh, that's a neat approach! It should be possible to set the executable in the metadata, something along the lines of

diagram:
  engines:
    cetz:
      execpath: quarto typst

Then we won't have to do the "create executables" step that seems to cause issues on the GitHub workflow runners.

Let me know if that doesn't work, then I'll try to make it work somehow.

[benabel]

This approach do not work:

diagram/diagram.lua: quarto typst: createProcess: posix_spawnp: does not exist (No such file or directory

[tarleb]

OK, I'll try to implement a fix. One moment.

[tarleb]

Please rebase to the current main and try with execpath: ['quarto', 'typst']

[benabel]

Ok I try that.

[benabel]

I fixed the arguments list to use quarto typst command and changed pandoc command to use quarto's pandoc in makefile. This should be OK now.

[tarleb]

Thank you! I'll add the missing make install step.

[tarleb]

Works beautifully! I'll make a new release within the next days.

[benabel]

@tarleb Thanks for your feedbacks during the pr. And again thanks for sharing this handful extension open source.
