Guix packaging often involves using regex to alter sources. So understanding this is really useful - a deep dive to cover all the parts of Guile's POSIX Extended Regular Expressions implementation.

This is part 1 covering basic literal matching, character sets, POSIX character classes and backslash shortcuts. Two further posts on the way!

Been working on it since May (now Sept) 😅

Loving the power of occur in #Emacs, specifically multi-occur-in-matching-buffers in my case, for finding and listing in a single buffer all #regex matches from regex-filtered buffers. Searching across .csv terminology files this way gives me a buffer of search results, each line of which takes me to the line of the source file where the occurrence appears. Extremely useful in #translation work for searching across terminology dictionaries I've created in the past.
