Vscode-powershell: $global:options['CustomArgumentCompleters'] in Powershell hosted in VS is $null...but it's false outside

[shanselman]

Issue Type: Bug

In a PowerShell window, run:

$global:options['CustomArgumentCompleters'] -eq $null

and note that it's TRUE

Now run the same command in a regular PowerShell window and note that it's FALSE.

This prevents a number of scripts from running within VS Code's PowerShell, including the popular "z" replacement for changing directories.

VS Code version: Code 1.21.1 (79b44aa704ce542d8ca4a3cc44cfca566e7720f1, 2018-03-14T14:47:13.351Z)

I suspect that the "z" change directory utility has some script that it puts in a profile file. If that script is in Microsoft.PowerShell_profile.ps1 it will not get run inside the PowerShell Integrated Console terminal window. If you move that script to profile.ps1 then it will get loaded by all hosts for the current user.

@shanselman So just to clear things up:

Results of $global:options['CustomArgumentCompleters'] -eq $null:

PowerShell Integrated Console (part of PowerShell extension): False
Regular PowerShell console in VSCode (ships with VSCode): True
PowerShell.exe/pwsh.exe: True
PowerShell ISE: <not sure>

Do I have this right?

Keep in mind that the ISE, powershell.exe, and the PowerShell Integrated Console are all different hosts and have their own unique profiles as @rkeithhill mentioned.

p.s. big fan of what you do and your work 👍

Yes, in fact, in the ISE it's "Cannot index into a null array." because #global:options is itself $null there as well.

OK, that's it - moving z's stuff into profile.ps1 fixed this. Thanks for your patience and guidance! Hopefully this gets google juice and helps someone else!
