Simple command-line utility for generating strings from regular expression patterns. Uses goregen.

Installation

Usage

Regen takes a regular expression as an argument, and prints the generated strings to standard out.

regen [args] pattern

where pattern is a regular expression. Run with -h for more information on arguments.

For example,

regen '[a-f0-9]{8}(-[a-f0-9]{4}){3}-[a-f0-9]{12}'

will generate a UUID (e.g. bc8c3f7d-1176-ae94-492a-2dab8fc06640).
