The images beside the samples were screenshots taken by hand, so they drifted: they still showed `package Carbon api;`, syntax the language dropped in 2024. `render_sample.py` renders a sample the way the grammar in this repository actually highlights it, using `tmlanguage.py`, a small TextMate tokenizer. VS Code runs grammars under Oniguruma, which we cannot depend on here, but this grammar uses no Oniguruma-only syntax, so `re` runs its regexes unchanged and the two agree on every character of every Carbon file in the repository. The output is SVG, so regenerating needs nothing but Python, and a later grammar change gets a same-path image diff showing what it did to real code. The samples change where a construct left the language (`api`, `Carbon` as the package name, `StringView`, `destructor`), refresh the `keywords.carbon` inventory against `token_kind.def`, and add sections for octal, raw and block literals, character literals, lambdas, and raw identifiers. `interop.carbon` is new, covering inline C++. These are highlighting fixtures rather than programs, so the deliberately invalid lines stay. Assisted-by: Claude Code --------- Co-authored-by: Dana Jansens <danakj@orodu.net>
