Using environment variables

[Haswell]

I need to open a path specified with Windows environment variables listed here:
https://www.rapidee.com/en/environment-variables

This code gives me an error:

Code: Select all

path := "C:\Users\%username%\AppData\Roaming\Code\User"
Run, "%path%"

I know about A_username but the path is specified by a user who doesn't know about AHK-variables.
I also don't want to convert "username" to "A_username" because it's a tricky way.
User also might use any variable which is not presented in AHK.
Would you kindly help me to fix it?

You can simply fix this error by using valid expression syntax (and not using #NoEnv):

Code: Select all

path := "C:\Users\" username "\AppData\Roaming\Code\User"
Run, %path%

Like this, you are using the username Env variable, but you are overwriting AHK's copy of the Path variable... but if you don't need it, that's ok.
Edit: there is also Env appdata available, see: msgbox % appdata

But tbh, I am not sure, if I understand what you specifically intend here. Probably you should read this: https://www.autohotkey.com/docs/Concepts.htm#environment-variables
With #NoEnv you could do this:

Code: Select all

#NoEnv
EnvGet, username, username 
msgbox % username
path := "C:\Users\" username "\AppData\Roaming\Code\User"
Run, %path%

Take a look at built in variables:
A_AppData
A_UserName
