- ChrisGranger 9y agoI'm fond of https://regex101.com/ https://regex101.com/ as well.
- testvox 9y agoThis site is what finally made me good at regex. I found it painful to learn otherwise.

[2] https://regex101.com/r/LzdGpw/1 https://regex101.com/r/LzdGpw/1 I can use 2, but 1 just looks cool.
- FridgeSeal 9y agoRegex101 is actually awesome. It's what I reach for whenever I've got to do stuff in regex.
- fergie 9y agoRegex101 is the daddy. I really don’t know how it could be improved.
- vanthiathevan 9y agoThat is cool. https://www.debuggex.com/ https://www.debuggex.com/ has nice visualization.
- noio 9y agoWow, that is really cool. I actually started typing in random characters and tracing the matches through the graph for the Regex from StackOverflow mentioned earlier. I didn't know what the regex matches, so I played it like a game , trying to reach the finish by typing one character at a time. When I finished, I saw that I had typed "01/31/1691" and then realised that it's a regex for dates.
- overlordalex 9y agoSounds like you'd love https://regexcrossword.com/ https://regexcrossword.com/
- BenjiWiebe 9y ago+1 for regex crossword. That's a lot of fun.
- dugluak 9y agoThat is so fast!
- paradite 9y agoI used regexr quite a lot during my daily work. I think regexper more suited for complex structures whereas regexr is better for checking the meaning of simple expressions because of the hover-over function.
- foobarchu 9y agoAgreed. I use regexr daily for building my regex's without having to execute the programs they'll be part of.
- jsilence 9y agoemacs also has a visual regexp builder mode (M-x re-builder) that shows the 200 first matches in the current buffer to validate that the regular expression does what you want. But AFAIR there are syntax differences between different regexp flavors and emacs uses the elisp flavor of course.
