The TM grammar for CodeQL includes an invalid Oniguruma regex. Specifically, in Oniguruma, lookahead is invalid when used within lookbehind. This leads to the regex failing silently in
vscode-textmate, and the regex doesn't match whatever it's intended to match.Additionally this makes the CodeQL grammar fail entirely when used with Shiki's JS engine (see CodeQL listed as unsupported in Shiki's compatibility list) because Shiki's JS engine doesn't fail silently for invalid Oniguruma regexes.
Because the lookahead appears at the end of the lookbehind, it is easy to just move it outside of the lookbehind, and the regex matches the exact same strings as were intended.
To make this change, I updated
extensions/ql-vscode/syntaxes/ql.tmLanguage.ymland then ran thesyntaxes/updateSyntaxscript to generate the JSON version of the grammar.
