grex

Simple command-line tool to generate regular expressions. More information: https://github.com/pemistahl/grex.

  • Generate a simple regular expression:

grex {{space_separated_strings}}

  • Generate a case-insensitive regular expression:

grex -i {{space_separated_strings}}

  • Replace digits with '\d':

grex -d {{space_separated_strings}}

  • Replace Unicode word character with '\w':

grex -w {{space_separated_strings}}

  • Replace spaces with '\s':

grex -s {{space_separated_strings}}

  • Add {min, max} quantifier representation for repeating sub-strings:

grex -r {{space_separated_strings}}
