Packages

Every package is published to npm under the @tabnas/* scope and, where applicable, as a Go module at github.com/tabnas/<name>/go. Each ships four-quadrant Diátaxis docs in both languages.

Grammars are plugins over other grammars, so the list below is closer to a dependency order than a catalogue: JSON is a handful of rules, JSONC adds comments to them, JSON5 and jsonic relax the quoting, and so on. Extending one of these is usually cheaper than starting a new grammar.

28 packages. Versions here are recorded in the site source and can lag a release — releases reads the live version from npm.
