### RegEx writing
Please note Hyprland uses Google's RE2 for parsing Regex. This means that all operations requiring polynomial
time to compute will not work. See [the re2 wiki](https://github.com/google/re2/wiki/Syntax) for supported extensions.
If you want to _negate_ a regex, as in pass only when the regex _fails_, you can prefix it with `negative:`, e.g.: `negative:kitty`.
