Online regular expression tester

I found a nice online regular expression tester under following URL.

https://regex101.com/#javascript

Some cool stuff it supports:

  • instant interpretation of regular expressions including a list showing which parts in the regular expression mean what
  • syntax highlighting
  • shows available groups in matches as well as the whole match when hovering a match
  • a regular expression library holding some crazy things like parsing csv files using regular expression (haha ... I like)

Enjoy.
