Typst CSS

[gordonwoodhull]

This is about ready to merge, once there is a new Pandoc release.

With full CSS rgb and named color support and the border shorthands, the Lua script to do CSS->Typst translation is about 4x as long as it was (now ~900 lines).

Posting the PR for review tomorrow as well as to see how the tests do.

Will follow up with open questions & areas to review, or bring those tomorrow.

This subsumes #9500.

Ah yes, will need Pandoc 3.1.14 to run the tests in CI

gt and Great Tables get some nice effects out of putting borders on spans.

See Time and Measurement in this gt screenshot:

It is also possible to put borders on a Typst #highlight() but it would take a lot more styling for it to look good, so I've disabled it.

Naive Typst #highlight with border (and transparent color 😮) looks like this:

gt is using width: 100% and display: inline-block, along with judicious padding on both th and span, so it's not exactly obvious how to map this automatically.

Pandoc 3.2 doesn't seem to cause any failures.

Rough edges we should probably handle before merging:

• for some reason, it's only finding 5 of the ff matrix tests on Linux, but all 174 of them on Windows. https://github.com/quarto-dev/quarto-cli/actions/runs/9069590810/job/24919483138?pr=9619
• (Intermittent?) mediabag failure on Windows: https://github.com/quarto-dev/quarto-cli/actions/runs/9068888314/job/24917216923?pr=9619
• ff matrix tests will occasionally time out on mermaid content, e.g. https://github.com/quarto-dev/quarto-cli/actions/runs/9068888314/job/24917216549?pr=9619
  It takes ten minutes for the test to time out. I only saw it twice and rerun works.

• (Intermittent?) mediabag failure on Windows: https://github.com/quarto-dev/quarto-cli/actions/runs/9068888314/job/24917216923?pr=9619

I wonder if this is because we're hammering placeholder.co and we should use some other solution instead.

1. I thought the globstar feature (eg qmd-files/**/*./qmd) seemed like a relatively "new" Unix feature (c2010 😉).
   Turning it on with shopt -s globstar && ..., all ff matrix tests are running.

2. I can repro the mediabag error locally with

quarto render document.qmd -t pdf -M keep-tex:true

Kind of weird, maybe coincidental.

• Does not happen without keep-tex
• File does not have any pdf options
• Don't think tests in CI run with keep-tex

[gordonwoodhull]

Okay, this is only blocked by mediabag issues on both platforms. It's weird that it's always the same file, and I can repro the error locally, but I am giving up on it for the moment.

I have some hardening to do on Typst CSS inputs and need to test malformed input, which I can do before or after merge.

quarto render document.qmd -t pdf -M keep-tex:true

Can you just clarify which document.qmd this is referring to?

[cscheid]

Ok - I think that failure is placeholder.co etc no longer being reliable.

[gordonwoodhull]

There are very occasional mermaid timeouts, but everything else is running well.

Ok to merge?

Let's do it!
