@nixCraft Since writing [make that being forced to write] my own compact, limited regex parser in C (still with back-pattern matching) many, many moons ago, A surprising amount of my subsequent income has been derived from writing regexes.
@abivia@nixCraft My own RE parser; a preprocessor to compose complex RE’s from simpler ones (after all, RE’s are closed under composition), etc. etc. - and in the end, a little grep here and there and the money just kept walking in. Maybe that’s a slight exaggeration. Slight.
