Issue Description

Hello! I posted this to VS Code and they referred me here (microsoft/vscode#31985 (comment))

I've noticed over the last couple days/week that VS Code is taking a very long time on "Formatting Document". I have my VS Code instance configured to format the document on every save, and I save constantly, so this is a real PITA. :( I have attached the contents of $env:APPDATA\Code\User to this report.

Steps to Reproduce

Steps to Reproduce:

Configure VS Code using my settings.json
Open up any Posh Script. I have encountered this on scripts with as few as 120 lines
Make a change
Save file
Blue bar at bottom of VS Code states "Formatting Document". VS Code is responsive, but Snippets and Intellisense do not function until it completes doing whatever it was doing.
Reproduces without extensions: No

Attached Logs

Follow the instructions in the README
about capturing and sending logs.

Actually now that I read this, I see you mention that it happens even on short scripts. Is it consistently slow even when you open up a fresh VS Code session and try it?

[RickFlist]

It does NOT repro if I launch code with the --disable-extensions parameter. Otherwise, it repros every single time, seemingly regardless of what extensions I have installed or the size of the script or the freshness of the session

[daviwil]

This issue is caused by the PowerShell extension, so that's really the only thing that matters in this case. I'll take a look at your logs tomorrow and let you know if there's anything you can try to narrow down the source of the issue.

[RickFlist]

Thanks. Not being able to use Snippets has really slowed me down. :\

[RickFlist]

I also just noticed that CTRL+SHIFT+O does not list all the functions in a module as well. I verified integrated terminal started and even killed and and restarted it. CTRL+SHIFT+O states "no symbol information found"

[RickFlist]

FYI, while working on something I accidentally moved my powershell.json snippets file. This resolved the performance issues.

[daviwil]

@kapilmb will look into this for the next release

[RickFlist]

The snippets file was a red herring, after about 30 minutes the perf issues came back. Is there a workaround? Not having intellisense is very annoying

[daviwil]

You could try turning off PSScriptAnalyzer in your settings:

"powershell.scriptAnalysis.enable": false

[RickFlist]

That seems to work. Thank you so much.

[RickFlist]

Fudge. It's back.

@RickFlist There is a good chance that the formatter is crashing, which is causing the problem. There are a few situations I can think of that that can cause it to crash but would like to know for sure what is causing the problem on your side.

Would it be possible for you to share the document on which this is happening so that I can find out the exact issue? Thanks!
