Intellisense autocomplete not working with Powershell (module version 0.6.1)

[lc9er]

VSCode Version: 1.2.1
Powershell Module Version: 0.6.1
OS Version: Windows 10

Steps to Reproduce:

1. Edit a ps1 file, verify language set as 'Powershell'.
2. Attempt to autocomplete a cmdlet like 'get-host', by typing 'get-'. No suggestions pop up.
3. Attempt to manually get suggestions by typing Ctrl-Space. VS Code replies "No suggestions"

Occasionally, I will receive Intellisense suggestions for one or two cmdlets, then it will stop working.

Same Problem here. Logfile says:

Thanks for the stack trace. Looks like a case of not regex encoding the completion item text before throwing it at regex. The + chars in g++.exe are getting interpreted as metacharacters. I thought I had fixed all spots where we did this but I must have missed some.

[rkeithhill]

@nerdfactor Are you sure you're using the 0.6.1 version of the extension? The failure mechanism I believe you are seeing was fixed in early February. The code that corresponds to the error message is:

!Regex.IsMatch(completionDetails.ToolTipText, 
    @"^\s*" + escapedToolTipText + @"\s+\["))

The escapedToolTipText for g++.exe comes out as g\+\+\.exe but error message you see doesn't show the metacharacters as escaped:

System.ArgumentException: "^\s*g++.exe\s+\[" 

Note the + and . metacharacters in g++.exe are not escaped. This makes me think VSCode is finding/loading an older version of the extension on your machine.

Manifest file states:

Identity Language="en-US" Id="PowerShell" Version="0.6.1" Publisher="ms-vscode"

The logfile starts with:

30.06.2016 11:25:38 [NORMAL] - Method "Main" at line 145 of C:\projects\powershelleditorservices\src\PowerShellEditorServices.Host\Program.cs

  Host application details:

    Name: Visual Studio Code Host
    ProfileId: Microsoft.VSCode
    Version: 0.6.1

so everything looks like Version 0.6.1.
The error only happens on my Windows 7 Machine at work that has Windows Management Framework 5 installed. On my Windows 10 Machine at home everything works fine. So it may be a Windows 7 related issue.

Here's my log file. Looks like the same error:

[rkeithhill]

@nerdfactor and @lc9er thanks for confirming the version.

[rkeithhill]

@Ic9er Are you on Windows 7 as well? Also, what text did you type before trying to get auto-completion?

[lc9er]

I am on Windows 10.

I get this when typing, "get-", or "show-". Any cmdlet it seems.

@lc9er Where is g++.exe installed on your system? Get-Command g++.exe | Format-List should show you the location.

[lc9er]

C:\strawberry\c\bin

It was installed as part of the Strawberry Perl Chocolatey package.

I am also having problems with Intellisense and variables autocompletation. Is there another version of the extension you can advise to install? It it possible to install an older version of the extension?

[daviwil]

I don't believe an older version of the extension is going to help with this issue. Did your problem start after the 1.4.0 release of VS Code got installed? If so, let's continue the discussion over on this issue: #231
