alt Hacker NewsSNOBOL, SPITBOL and the Icon and Unicon languages are heavy with pattern matching.
There’s a book on “Snobol for the Humanities” but it doesn’t have a strong focus on UI; everything at the time it was written used a simple terminal interface like a REPL with no advanced terminal handling.
I wrote some SNOBOL IV programs back in the day and met Ralph Griswold when he visited the UCLA Computer Club. Fun language with very interesting ideas. Looking into Unicon is on my list of things to do.
