Linter for (Pygments) regular expressions

Project description

Regexlint will examine all regular expressions in an importable Pygments lexer, and report things that are probably not doing what you think they’re doing. For example, patterns like this (which will only match the first):

(else|elseif)

It can also warn about a few syntax problems, for example this has two problems – the \s+ outside the groups, and not enough actions in bygroups (this one needs two in the args to bygroups):

(r'(foo)\s+(bar)', bygroups(Blah)),

Usage

make demo
    or
regexlint pygments.lexers.web:HtmlLexer
    or
python2 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
