Project mention: Compile time regular expression in C++ | news.ycombinator.com | 2023-09-12

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).
