rakubrew init on Windows tells me to run rakubrew init for PowerShell instructions

[ugexe]

The instructions from rakubrew init tells me to run rakubrew init for powershell instructions. Yet I'm already running that command from powershell.

(Note that the above does not enable auto-loading in PowerShell, that needs a
separate installation procedure. Call C:\rakubrew\bin\rakubrew.exe init in a PowerShell window
for respective installation instructions.)

PS C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools> C:\rakubrew\bin\rakubrew.exe init
To load rakubrew in CMD automatically you have to do two things:

1. Check that you don't already have a CMD autorun script set.

    reg query "HKCU\Software\Microsoft\Command Processor" /v AutoRun

  If you don't have an autorun script set (the above command returns an error) you can set one using:

    reg add "HKCU\Software\Microsoft\Command Processor" /v AutoRun /t REG_EXPAND_SZ /d \""%"USERPROFILE"%\Documents\CMD_profile.cmd"\" /f

2. Add the following code to the end of the autorun script you linked in step 1:

    @echo off
    setlocal EnableDelayedExpansion
    set "cmd=!cmdcmdline!"
    if "!cmd!" == "!cmd:/=!" (
        endlocal
        FOR /f "delims=" %%i in ('"C:\rakubrew\bin\rakubrew.exe" init Cmd') do @%%i
    )

  You can easily do that from a CMD prompt using the following command:

    (
    echo @echo off
    echo setlocal EnableDelayedExpansion
    echo set "cmd=!cmdcmdline!"
    echo if "!cmd!" == "!cmd:/=!" ^(
    echo     endlocal
    echo     FOR /f "delims=" %%i in ^('"C:\rakubrew\bin\rakubrew.exe" init Cmd'^) do @%%i
    echo ^)
    ) >> "%USERPROFILE%\Documents\CMD_profile.cmd"

  If you use a different autorun script location, replace the path in the command above.

(Note that the above does *not* enable auto-loading in PowerShell, that needs a
separate installation procedure. Call `C:\rakubrew\bin\rakubrew.exe init` in a PowerShell window
for respective installation instructions.)

The logic to detect whether it's PS or CMD is here. It relies on some env var trickery. (See those 6 lines of code and the linked StackOverflow explanation.) Can you check how the environment looks on your machine? Maybe you can identify some other clue that gives away whether we're in a PS or CMD?

PS C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools> echo $env:PSMODULEPATH
C:\Program Files\WindowsPowerShell\Modules;C:\Mac\Home\Documents\WindowsPowerShell\Modules;C:\Program Files (x86)\WindowsPowerShell\Modules;C:\WINDOWS\system32\WindowsPowerShell\v1.0\Modules

PS C:\Program Files (x86)\Microsoft Visual Studio\2022\BuildTools> echo $env:USERPROFILE
C:\Users\nlogan

I don't see anything else in my environment variables that could be used to signal the shell being used either. I'm kind of thinking there is not a good way to tell which shell a user is using. Giving instructions for both powershell and cmd could be a less than ideal solution.

Looking at your output, I think the C:\Mac\Home\Documents\WindowsPowerShell\Modules thing is the path we are looking for. It's not at the begining and it's some other home, but it's a home.

Given that usage slowly shifts from CMD to PS, we could err on the side of PS and simply check, whether $env:PSMODULEPATH contains \Documents\WindowsPowerShell\Modules;.

Can you validate whether that would work on your setup (i.e. what does that variable look in a CMD)?

[ugexe]

Looking at your output, I think the C:\Mac\Home\Documents\WindowsPowerShell\Modules thing is the path we are looking for. It's not at the begining and it's some other home, but it's a home.

To me that seems like an artifact of Parallels and however it was configured to share disk access. In other words I suspect it would be possible for that path to not exist in my environment regardless of powershell, although it is true that the path does not show up in PSModulePath on cmd. Then again maybe it would always exist in some form, just not as a path to the documents folder on my mac.

I hope I have it sufficiently fixed in v42. I implemented both, shell detection now leans more on the PowerShell side and the init text now shows which shell was detected and how to get info for other shells should the detection have been wrong.
