Regexp testing tool allows to apply group of regexps to huge arrays of data (millions or so) in order to investigate search or search/replacement possibilities of regexp group.
- Works fast on huge arrays of data (millions or so)
- Allows to apply multiple regexp group and remember results of this (checkpoint)
- Allows to compare results of one regexp group vs other regexp group (checkpoint comparision)
Great for everybody who use regexps often :)
