One for the developers: variable name length

[LarsJ]

JohnOne, Your test still shows an overhead of about 25% just because of long variable names. That's much more than I would have expected. The overhead in my test is about 125% (this situation seems to be the case for function names in the standard UDFs).

What Melba said.  Why isn't the au3stripper parameters reversed?  Meaning, var/func renaming be on by default, unless specified otherwise.

Because when your script throws an error, obfuscated variable names make it hard to debug. This kind of optimization should obviously be inside AutoIt and the au3stripper is simply a workaround until such time that the AutoIt interpreter is optimized.

Please elaborate.  I don't think a compiled exe will give you the variable names, it just gives the error string and the line number, which is the line number of the exe not your script.

TouchOdeath Au3Stripper

A compiled exe will only give you the line number if an error occurs.

The simply reason is that I don't want to modify variable and func names by default.

Ok, good enough, thank you Jos.

The performance gained by using short variable names isn't exclusive to compiled scripts. For example, I exclusively run straight from source.

Another important thing is reuse variable if doesn't needed anymore on next sequence.

Variable given name such as $_, $__, $___, $____, $_____ and etc. Unreadable aren't it

Func dontlook_a()
   Local $_ = 'long text...' & _
              'long text...' & _
              'long text...' & _
              'long text...' & _
              'long text...'
   ; do something else with $_
EndFunc

Func dontlook_b()
   Local $_
   $_  = 'long text...'
   $_ &= 'long text...'
   $_ &= 'long text...'
   $_ &= 'long text...'
   $_ &= 'long text...'
   ; do something else with $_
EndFunc

I do that a lot, usually with a Local scope variable named $vTmp.
