Hi Folks,

Some thoughts on this by others please

First time I have needed to remove leading and trailing whitespace from a string. Turned to the following functions but got misled (not too difficult at my age). It is traditional in most basics and Xbases that rtrim and ltrim are used to remove said spaces. However it would seem that in their present format, these functions are surplus to requirements anyway because they both can be implemented with StringMid as demonstrated below
-------------------------------------------------
Functions in question:
StringTrimLeft , OutputVar, InputVar, Count
StringTrimRight, OutputVar, InputVar, Count
-------------------------------------------------

;StringTrimLeft implementation
StringMid, OutputVar, InputVar, 1, Count

;StringTrimRight implementation
StringLen, LenOfStr, InputVar
StringMid, OutputVar, InputVar, LenOfStr, Count , L

In fairness, this does seem to be an AutoIt artefact ?? QED Smile

And thanx to AHK we have more power to the elbow.
Thanx Chris Very Happy

Look like it's already available Wink

AutoTrim
--------------------------------------------------------------------------------

Determines whether SetEnv and "var = value" statements remove spaces and tabs.

AutoTrim, On|Off

Parameters

On|Off On: tabs and spaces at the beginning and end of a string are removed from a variable whenever it is assigned a new value. This mirrors AutoIt2's behavior and is the default.

Off: tabs and spaces are not removed.

BoBo is right. Since AutoTrim is on by default, all you need to do to get rid of leading and trailing whitespace is to assign a variable to itself:

Var = %Var%
