Cheaper string.Trim* functions for E2

[Astralcircle]

I took some code from Starfall to make the regex check less strict

Didn't you have an even faster implementation with string.byte? These funcs don't have a pattern matching input so you could use the string.byte one.

[Astralcircle]

Yes, but i only made them for string.Trim and string.TrimRight, so i decided to force all functions to use patterns for consistency, but i can probably just write a custom implementation for string.TrimLeft as well?

TrimLeft and TrimRight are the same as Trim except they only search one side, so yeah it should be easy to just have two local functions that search the left/right and then just

function string.Trim(s) return string.sub(s, findLeftTrim(s), findRightTrim(s)) end
function string.TrimLeft(s) return string.sub(s, findLeftTrim(s)) end
function string.TrimRight(s) return string.sub(s, 1, findRightTrim(s)) end
