I tried to follow a middle-of-the-road works mostly everywhere made up flavour. Here is a grammar for it: https://blog.robertelder.org/regular-expression-parser-grammar/ https://blog.robertelder.org/regular-expression-parser-gramm... I may add to it in the future if there is enough interest. At the moment it doesn't support a few common things like word breaks and backreferences, but I don't think it'd be too hard to add.
