Description of changes

Hey folks! Most of my work was behind the scenes, again. This is also my last invoice in ±6 months. I’ll remain active but need to focus most time off for one particular unified project.

Some highlights of what I did this month:

• replace skypack with esm.sh in install sections, which works great with all unified packages I tested it with, is actively maintained, and has great ESM/import maps/exports maps support, compared to skypack which is unmaintained and has a bunch of bugs on unified packages
• update to react 18 wherever we use it
• improve some more docs and add some .gitattributes w/ linguist-vendored to places to solve GHs language classification (e.g., remarkjs/remark-html@fc6fb94, remarkjs/remark-math@63a5f76)
• improved dynamic importing in MDX (Fix support for baseUrl rewriting import.meta.url mdx-js/mdx#2021) and positional info and a crash
• options.ignoreUnconfigured in unified-engine, for the language server Add options.ignoreUnconfigured unified-engine#64

I also spent time reverse engineering how GH processes the HTML after their markdown parser. Much of unified focuses on matching GitHub, but where GFM begins, what GitHub does is, is all vague, and reverse engineering is hard. Recently I made create-gfm-fixtures to help with that, which uncovered some of the tasks that GitHub performs in its pipeline: notranslate on code and pre (in comments), color chips (in comments), mentions (in comments), references (in comments), headings self-links (in files), syntax highlighting, add dir=auto to a some flow elements, gemoji to <g-emoji>, nofollow on <a>, style and '_blank' on img, but also an image CDN called camo, and a bunch of other random markup changes.
I am pretty far, but I’m waiting on some work to happen in Shiki so that syntax highlighting can match GH too, so this whole project is not yet ready to be released. I’m also not yet sure how most of this should be released. Presets? Plugins? Some things will probably be turned off because folks won’t have an image CDN or emoji images hosted somewhere?
Anyway, just wanted to mention this work as it’s a lot of work that I don’t have much to show for yet.
