Project mention: grex 1.0.0 - Generate regular expressions from user-provided test cases | /r/Python | 2023-08-31
The homepage has a benchmark that compares Zed's "insertion latency" to other editors, and this is the description:
> Open input.rs at the end of line 21 in rust-lang/regex. Type z 10 times, measure how long it takes for each z to display since hitting the z key.
Could someone clarify what that means? My interpretation of that was to go to https://github.com/rust-lang/regex/blob/master/regex-cli/arg... and start typing 'z' at the end of line 21, but that doesn't seem to make any sense. I guess that repo got refactored and those instructions are out of date?
Admittedly I did copy most of the regexes from https://github.com/lorey/social-media-profiles-regexs and updated some of them where needed.

rawr/t-regx: PHP regular expression brought up to modern standards.
Ha, nice to see this on HN: this article was pretty helpful to me to understand the concept a few years back when extending my PEG parsing library [1] with a Pratt parser; this mitigates the problem of PEG parsers not allowing left recursion and allows for a much more concise notation of grammars with operator precedence. Thank you Bob:

I've never used cl-ppcre myself, but its docs[1] claim that it provides compile-time regexes:
> CL-PPCRE uses compiler macros to pre-compile scanners at load time if possible. This happens if the compiler can determine that the regular expression (no matter if it's a string or an S-expression) is constant at compile time and is intended to save the time for creating scanners at execution time (probably creating the same scanner over and over in a loop).
