vsvars2010.ps1

A new version of Visual Studio is just around the corner, so it's time for my newest member of the scripts folder: vsvars2010.ps1.

This PowerShell script will set up your environment to run all the development tools from Visual Studio 2010. This new version contains an interesting little coalesce function (named ??, appropriately) that makes the function exceptionally compact, especially when compared to the .BAT versions for use with CMD.EXE.

I tested this with 64-bit Windows 7; I'd appreciate if anybody finds any bugs with 32-bit or older OSes to let me know. Also, if you've installed C++, I've only put the 32-bit compilers into the path; I'll leave it as an exercise to the reader to figure out how to make the appropriate 64-bit compilers show up.

Update (Mar 21): Apparently test-path doesn't like when you pass it null, so I made a couple changes to the script to also do null checks.

    PARAM([object[]] $values)

    $values | %{ if ($result -eq $null) { $result = $_ } }
    return $result
}

        [string] $newPath,
        [string] $envVar = "PATH"
    )
    $envPath = ("Env:\" + $envVar)
    $oldPath = get-content $envPath -ea:SilentlyContinue
    if (($newPath -ne $null) -and (test-path $newPath)) {
        if ($oldPath -ne $null) { $newPath = $newPath + ";" + $oldPath }
        set-content $envPath $newPath
    }
}
