Vscode-powershell: Integrated Console looks odd after a clear

[glawrence]

Issue Description

The PowerShell integrated console does not position the prompt and cursor correctly after a "Clear" is issued. I thought this might have been VSCode itself but https://github.com/Microsoft/vscode/issues/66850 suggests it is the extension.

• Open a PowerShell script and execute it via "Run active file in active terminal"
• Observe output in the integrated console window
• Right click in the console and select "Clear"
• Notice that the prompt is now at the top of the window
• starting to type or pressing the up arrow show that the cursor is actually still at the bottom and does not line up with the prompt

Attached Logs

I don't think logs are necessary but I can do this if it is needed.

@glawrence Would you be able to attach some screenshots describing what it is you (1) are seeing and (2) expect

[glawrence]

I have updated to PowerShell Extension Version 1.11.0, then:

• I loaded a .ps1 in VSCode which just does some stuff with output
• ran it via "Terminal: Run Active File in Active Terminal"
  
• Pressed Clear (Cmd+K) in the Integrated Console to clear the output
  
• Then pressed the up arrow to run it again
  
  Then you can see the prompt at the top of the console and the cursor at the bottom. Hopefully that helps now.

Not sure if it is related. If I select a function body in editor and press F8, then in terminal,
1) use Arrow Up;
2) run Get-Help My-Func

The help text is not readable. I guess F8 might have "typed" in every line of selected code which messed up the terminal. I have to manually clear the terminal to get it to normal.

This should be fixed in the latest version of the PowerShell extension 😃 I'm going to close this now but please let me know if you're still seeing this.

[glawrence]

On my Mac I have PowerShell 7.0.0 with VSCode 1.44.2 and the PowerShell extension 2020.4.0 and I can reproduce the problem @TylerLeonhardt

[TylerLeonhardt]

You're right - I was following different steps.

[TylerLeonhardt]

That said, I don't know if the _terminal_ is communicating that the cursor position has changed... as I can repro in _not_ the PS Integrated Console:

@Tyriar any thoughts here?

this either needs to go to Microsoft/vscode or PowerShell/PowerShell.

Thanks @Tyriar ! I'll close this as a duplicate to that one.
