Ah, that seems really nice.

and i case incensitive

Regex isn't a programming language tho

More like language theory

it's a regular expression for text searching

can I get a quick rundown?

it recognize pattern

what is it for

Searching text for patterns

here

https://en.wikipedia.org/wiki/Regular_expression

something like this for example : `/[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,}$/i` will recognize an email address

so what email address would that be?

any

or do you mean, if you define symbols

it define the pattern that makes an email address valid

like what was going on with that romanji

I mean

it was just used as a simple search and replace

you can either match a pattern, or replace a pattern with regex

yeah, what I was using wasnt regex
