🔮 Write readable regular expressions

The crate provides a clean and readable way of writing your regex in the Rust programming language:

Without pretty_regex	With pretty_regex
\d{5}(-\d{4})?	digit() * 5 + (just("-") + digit() * 4).optional()
^(?:\d){4}(?:(?:\-)(?:\d){2}){2}$	beginning() + digit() * 4 + (just("-") + digit() * 2) * 2 + ending()
rege(x(es)?|xps?)	just("rege") + (just("x") + just("es").optional()) | (just("xp") + just("s").optional())

How to use the crate?

To convert a PrettyRegex into a regex from regex crate, you can call to_regex or to_regex_or_panic:

use pretty_regex::digit;

let regex = (digit() + ascii_alphabetic().optional()).to_regex_or_panic();

assert!(regex.is_match("3"));
