Here's my latest favorite. In a few tests I did, it slightly outperformed your variant, except for the all-space strings, where it performed worse (which I don't understand why).Here's the latest proposed version: local match = string.match function trim(s) return match(s,'^()%s*$') and '' or match(s,'^%s*(.*%S)') end
function trim(s)
local from = s:find("%S")
return from and s:match(".*%S", from) or ""
end
