Brendan Hansknecht (Mar 21 2024 at 00:37): Brendan Hansknecht (Mar 21 2024 at 00:37):I could be wrong, but I'm pretty sure python is an example of a modern programming language that uses a grammar and parser generator.
Brendan Hansknecht (Mar 21 2024 at 00:49):Yeah, peg grammar using pegen which I think was built specifically for cpython
Brendan Hansknecht (Mar 21 2024 at 00:49):And is relatively new if I recall. Like they switch to it in the last 5 or so years
Richard Feldman (Mar 21 2024 at 10:41):huh, interesting! I wonder what motivated the switch

Zellyn Hunter (Mar 25 2024 at 16:08):That may be more common for SQL parsers. sqlite (and pikchr) use the lemon parser generator, also written by D Richard Hipp. I ported lemon to Go as part of porting pikchr to Go.
