else: The term 'else' is not recognized as a name of a cmdlet, function, script file, or executable program. #3087

Issue Description

I am experiencing a problem with...
else is not recognized as a name of a cmdlet, function, script file, or executable program when using the "Format Document" feature.

Format Document (creates the error)

$x = 5
if ($x -eq 5) {
	"x = 5"
}
else {
	"x not equal 5"
}

Manual edit (now works)

$x = 5
if ($x -eq 5) {
	"x = 5"
}else {
	"x not equal 5"
}

BOTH of these work when run from PowerShell ISE or running the code via a normal powershell console.
vscode for some reason does not like else being on a new line.
This behaviour is the same for Windows PowerShell 5.2 and PowerShell 7.1.0

I use Format Document for all my scripts and I've never run into this issue with 'else' previously so do not know if this is a new bug introduced recently??

There hasn't been a new release in several months, so unless you just upgraded it seems unlikely.

There is a known issue with formatting where it seems to race the extension's file system abstraction, discussed in #2569. I suspect this is the same issue -- which also explains why you might not have hit it before.

One remaining question -- the first script snippet you posted is valid and runs as I expect (PowerShell allows you to hang the else):

Are you seeing the parse error on that particular script?

executing code snippet directly in vscode after Ctrl+A to select all and then F8:

Can you report the output of gmo PSReadLine in the integrated console?

So I uninstalled the PowerShell extension and reinstalled it and its now working as expected.

closed vscode and opened it again and the integrated terminal is gone and the issue returns

PART FIXED:
I had "powershell.integratedConsole.showOnStartup": false,
changed it to "powershell.integratedConsole.showOnStartup": true, and the issue is now resolved in the sense that it now works as long as the terminal is running the PS Integrated Console:

If I change the console to powershell it fails again:

TylerLeonhardt · 2020-12-11T18:09:45Z

That's because pressing F8 when dealing with "not the PowerShell Integrated Console" just throws the text in the editor into the terminal window.

With the "PowerShell Integrated Console", we do something differently (sending a message behind the scenes with the full script to make sure the full script gets run). We can do this because it's "Integrated".

I'm not sure what can really be done about this behavior unless PSReadLine supported Paste Bracketing:
PowerShell/PSReadLine#1471

Thanks for the clarification Tyler. At least I know going forward to use the integrated console and I now understand a bit better what it does in the background. 👍

Be sure to give that PSReadLine issue a like :)
