Variable 'username' auto-defined in scripts

[kellianjaxon]

Environment:
Windows 7 Enterprise
AHK 1.1.29.1 Unicode 32-bit

Symptom: Execute the command 'msgbox % username' in the first line of a script.
Expected behaviour: Display an empty messagebox.
Actual behaviour: Display a messagebox as if there was a prior assignment 'username := a_username' in the script.

Yeah and this is why you should use

Code: Select all

#NoEnv

on top of your script.

Some background: This is an environment variable that is set for the AutoHotkey process.
If you dont use #NoEnv Autohotkey will get the values of these environment variables instead of no value - like you expected.
Another example is PATH.

Ah, of course. It didn't occur to me 'USERNAME' actually is by default an environment variable, having hardly ever used that one.

Thanks for the clarification! My bad.
