Issue #20519 has been updated by shyouhei (Shyouhei Urabe). Status changed from Open to Feedback Ruby (especially its multilingualized string) is built on top of Onigmo and not vice versa. You must first decouple them, which alone is not an easy task. ---------------------------------------- Misc #20519: Porting regexp to pure ruby? https://bugs.ruby-lang.org/issues/20519#change-108603 * Author: brightbits (Michael Baldry) * Status: Feedback ---------------------------------------- Would there be any benefit in porting Regexp from Onigmo to a pure ruby implementation that could benefit from YJIT? Compiling a pattern could be translating to a ruby method which would be optimized by YJIT easily. Has this been explored or any work done around this kind of thing, before I take a look in to it more? Many thanks -- https://bugs.ruby-lang.org/
