# crex
Explore, test, and check regular expressions in the terminal.

![crex example](https://raw.githubusercontent.com/octobanana/crex/master/assets/crex.png)

Given your regular expression and text, crex will output matches, capture groups, and details.
crex has a range of options, allowing fine grained control over matching and output.
It uses ECMAScript grammar by default, while also accepting posix, extended posix, awk, grep, and extended grep grammars.
Input can be received by piped stdin, or by using the __-s__ option.
Output options include plain, colour, and json formats.
