Details

ripgrep has no support for look-ahead/look-behind:

% rg '(?!LUA)_LIBDIR'
regex parse error:
(?!LUA)_LIBDIR
^^^
error: look-around, including look-ahead and look-behind, is not supported
Consider enabling PCRE2 with the --pcre2 flag, which can handle backreferences
and look-around.

It would be nice if this would be enabled via `--pcre2`.

(just for completeness, I've meant to use `'(?<!LUA)_LIBDIR'` after all)

What happens if you use `rg --pcre2 '(?<!LUA)_LIBDIR'` ? See also [1]

Oh, that works - I've read it as a flag to be used when building, not a runtime one.

Thanks!

Note: there is `--auto-hybrid-regex` flag to use it automatically (https://github.com/BurntSushi/ripgrep/commit/967e7ad0de3e657e8f81c1384a48ca1eea4edde7).
