digitalmars.D - Towards better regex - rewind-regex
- Dmitry Olshansky (11/11) Jun 24 2023 So some of you may have heard about
- Dmitry Olshansky (2/13) Jun 24 2023
- Chris Katko (4/15) Jun 24 2023 I just want to say, I really appreciate this work.
- Dmitry Olshansky (8/27) Jun 24 2023 It saddens me greatly to hear about that, suffice it to say new
- Richard (Rikki) Andrew Cattermole (7/9) Jun 25 2023 Templates weren't the issue.
- Sergey (6/17) Jun 25 2023 Comparable with performance in this bench
- Dmitry Olshansky (2/23) Jun 26 2023 Full force:)
So some of you may have heard about rewind regex, a new radical effort to rebuild and redesign std.regex. I’m collecting feedback, in particular what feature you may want to sacrifice in the name of performance. https://github.com/DmitryOlshansky/rewind-regex — Dmitry Olshansky CEO at Glow labs https://sponsr.ru/glow https://patreon.com/dmitry_glow_labs

You want to be very careful with the std.uni tables, don't initialize them at CTFE unless you can help it. This is what my big bad PR for std.regex that was merged recently prevented. A whopping 500ms. Either way, its fixed now thanks to time trace!
