Here are two trim whitespace functions that had written. To my surprise the regex variant is way, way faster!
-- -- regex method -- function trim pText get replaceText(pText, "^\s+", empty) return replaceText(it, "\s+$", empty) end trim
-- -- non regex method -- local lWhitespaceChars
on startup -- prepare list of characters to be used by trim() -- CRLF = ascii 13+10 put tab & space & CRLF into lWhitespaceChars end startup
function trim pText repeat while char 1 of pText is in lWhitespaceChars delete char 1 of pText end repeat repeat while char -1 of pText is in lWhitespaceChars delete char -1 of pText end repeat return pText end trim
For an easy "trim" function that is just as fast as regex, try this:
return word 1 to -1 of pText
In a test using text with 1000 leading white space characters and 500 trailing characters, the difference between the regex method and the above one-liner was one millisecond.
