Three reference files, each stating whether a fact was measured, read from source, or asserted — an unattributed number is a rumour. math-on-the-web: MathML is the only no-JS route, the one pure-Go TeX→MathML library is an untagged 2023 commit, and writing MathML directly costs nothing since raw HTML renders. syntax-highlighting-choices: chroma is two modules and ~5MB, every alternative a search returns is JavaScript, and custom lexers load from XML at runtime without a rebuild. goldmark-behaviours: the seven surprises that caused or nearly caused defects — strikethrough claiming a single tilde, delimiter runs pairing across whitespace, per-parse heading id counters, footnote id prefixes, raw HTML being dropped rather than escaped, the language class already in the output, and ParseFS globbing.

Rendering maths without JavaScript
Established 2026-08-02 by searching, then querying the Go module proxy directly. Re-check before relying on the library situation; the browser facts are stable.
The shape of the problem
KaTeX and MathJax are JavaScript. A site that refuses client-side script cannot use them at runtime, so the only no-JS route is TeX → MathML at render time. MathML is native browser markup: Firefox and Safari have supported it for years, Chromium since 2023 (MathML Core). No script, no font loading, no layout pass of our own.
Go libraries, as of August 2026
| Module | State | Verdict |
|---|---|---|
git.sr.ht/~mekyt/latex2mathml |
Pure Go, a port of the Python library of the same name. No tagged release — latest resolves to v0.0.0-20231214134936-808832af73fc, a bare commit from December 2023. sourcehut returned a 502 while this was checked |
The only real candidate, and the weakest dependency this project would have taken |
codeberg.org/go-latex/latex |
Properly versioned (v0.3.0), maintained | Wrong output — it draws equations, MathJax-style, rather than emitting MathML |
jgm/texmath |
Mature, well maintained | Haskell. Usable only as a service, which fails the sovereignty test |
go list -m -versions git.sr.ht/~mekyt/latex2mathml prints the module path with no versions after it, which
is how an untagged module reports.
The option that costs nothing
Since raw HTML renders for site-root content (ADR-0060), MathML can be written straight into a bundle.
Verbose by hand, no dependency, no script, correct output. $…$ sugar can be added later over the same
output without changing anything downstream, so choosing this now forecloses nothing.
