The job I was born for:
@gruber have any good regex resources you like for beginners to use?
@gregmarra I’m not sure about beginner resources. BBEdit’s regex playgrounds are awesome for testing/tweaking patterns against sample text. And the BBEdit user manual chapter on “Grep” (BBEdit’s longstanding synonym for regex) is highly-regarded. (I wrote large parts of that chapter, 20 years ago, when BBEdit switched to the PCRE engine.)
