Regexlint is intended to be run as a linter against an importable Pygments lexer, and flag problems that will prevent the lexer from performing well (since we don’t have branch coverage for lexers :)
As a simple example, alternations are first match, so it will flag this as never matching “elseif”:
(else|elseif)
It also understands some Pygments internals, for example bygroups(...)` needs to have the same number of args as the regex has capture groups. Too many will result in duplicate text; too few will result in missing text. There should also not be any gaps between the capture groups, so this example flags two problems:
(r'(foo)\s+(bar)', bygroups(Blah)),
Usage
make demo
or
regexlint pygments.lexers.web:HtmlLexer
or
python3 regexlint/cmdline.py pygments.lexers.web
Todo
Figure out which phase should remove unnecessary backslashes
Write the alternation expander, so that ([ax]|a[bc]) fails the alternation order checks
Make more general than just for Pygments
