Hi,

I'm now missing that Transform, Deref does not expand environment variables anymore (due tue #NoEnv). Maybe there could be added a new command DerefEnv to Transform which also expands environment variables. Another solution could be EnvGet, *All.

Since #NoEnv operates at a low level, adding the ability to expand environment variables is somewhat difficult. In addition, I wouldn't expect such a feature to be used by very many people. For these reasons, perhaps some non-built-in solution can be found such as:

EnvGet, MyEnv1, MyEnv1
; ...etc.
Transform, OutputVar, Deref, ...

In other words, by fetching all your environment variables into identically-named normal variables (assuming you know all the names), you could then use Transform Deref as though #NoEnv weren't present.

Alternatively, perhaps you could use DllCall and GetEnvironmentStrings() to get the complete list of environment variables, then parse the list and use EnvGet on each one.

Hi Chris,

thanks for the idea with parsing the list of all envvars. I'll try that.

Hi,

GetEnvironmentStrings just returns a numeric value. It's a pointer to the environment block, but how to read this environment block?

You could use the CMDret function (no external .exe or .dll needed in this version) to retrieve the variables, values. Then, parse the output.

Thanks,

well not the fastest way, but it works. Strange that Envget, %uh_EnvVar1%, %uh_EnvVar1% does not work.

Without using an external DLL:

Hey! Thanks! That's great and quite faster.

Sometimes this strange variable (=::=::\) is present, sometimes - is not present.
But such way always passes the first variable (even if it another)

Hello,

btw. the routine crashes on systems which have environment-variables with characters, which arent allowed in autohotkey. Users reported they have variables like {32134:34234:32234:34324}.

Hi,

the variable is set from outside and not inside a script. { and : are illegal characters for AutoHotkey but not for Windows.

I do not see a difference between the set of a variable inside or outside of script. But well. I set this variable via standard applet, and script works well and in this case too.

Ok, you're just listing the variables. But if you try to set them in AutoHotkey you'll get the error because it's not allowed to use:

{32134:34234:32234:34324} = anystring
