REXS is a language to create regular expressions. It can be used to create more readable and easy-to-modify expressions that compile to clean and readable regular expressions.


For more information on REXS' syntax (or how to use it), take a look at https://esolangs.org/wiki/REXS.

## Example

An example usage of REXS can be to match on any URL that starts with http:// or https://, then match any subdomains, followed by the domain and .com:

```rexs

assert(START);

match("http");

repeat(0, 1) {

    match("s");

}

match("://");

repeat(0, inf, nongreedy) {

    repeat(1, inf, nongreedy) {

        match(ANY);

    }

    match(".");

}

group() {

    repeat(1, inf, nongreedy) {

        match(ANY);

    }

    match(".com");

}

assert(END);

```

This example will be compiled to `/^https?:\/\/(?:.+?\.)*?(.+?\.com)$/`.
