Extension doesn't start up when files.exclude values are non-boolean

[BooTheHamster]

Powershell integrated console hangs on when I open powershel source file. Running any powershell code by pressing F5 also hangs on.

Attach output console log, terminal window screenshot and logs.

[TylerLeonhardt]

Do you have any privilege management software or antivirus software installed on this machine? We've heard reports that these slow down start up...

[BooTheHamster]

No.

[SydneyhSmith]

@BooTheHamster thanks for the logs could you please also provide any settings you have in vscode?

[TylerLeonhardt]

@BooTheHamster can you explain this line in your settings?

"**/*.js": { "when": "$(basename).ts"} in files.exclude...

I think if you remove that, you won't see this issue.

[rjmholt]

Looks like this is an (as far as I can tell) undocumented but used syntax. In order to accommodate it we'll need to either make parsing it fail nicely or implement a custom JSON parser for it

[BooTheHamster]

can you explain this line in your settings?

Old settings to hide *.js files when correcponding *.ts file exists.

@TylerLeonhardt thanks, I remove this settings and issue gone.

[TylerLeonhardt]

I've reopened this to track us handling this setting better.

[conscribtor]

I'm running into this issue as well when using the following settings:

    "files.exclude": {
        "**/__pycache__": true,
        "**/*.pyc": {
            "when": "$(basename).py"
        }
    },

Since it's just a QOL setting, I've removed it to make it work.

[YipYipX4]

I also get the failure with the following files.exclude settings:

    "files.exclude": {
        "**/*.pyc": {"when": "$(basename).py"}, 
        "**/__pycache__": true
    },

The first of those settings will hide compiled Python 2 output files as long as the corresponding *.py file is present (but if you delete or rename the original file, then the *.pyc file will show up in the File Explorer pane). The second of those settings hides the directory where Python 3 compiled output is stored.

Below are the exception and call stack reported in the PowerShell Editor Services output pane. Looks like the problem might originate near ConfigurationHandler.cs line 52?

[TylerLeonhardt]

Thanks for the extra info. We have a good idea where the problem is:

https://github.com/PowerShell/PowerShellEditorServices/blob/03373ae00cf1730da48d31cfa4c48c359d2952b1/src/PowerShellEditorServices/Services/Workspace/LanguageServerSettings.cs#L407-L431

See the use of Dictionary<string, bool>... that doesn't get deserialized correctly when we get "**/*.pyc": {"when": "$(basename).py"}

Not sure if @david-driscoll has any ideas here on the best way to handle this... but we probably need this to be a Dictionary of <string, BoolOrWhen> where BoolOrWhen is a class:

class BoolOrWhen
{
    public bool HasBool => _boolValue != null;
    private bool? _boolValue;
    public bool Bool => _boolValue ?? false;
    
    public bool HasWhen => When != null;
    public string When { get; private set; }
}

and then we have a Newtonsoft serializer that will handle turning what's given into this class.

With all that said... we've got a lot on our plate right now so this isn't the highest priority issue, unfortunately. If someone wants to help out and pick this up, we can probably be able to assist in walking through this.

I observed this issue today and spent a few hours trying to get my debugger to connect.

I modifed settings.json from:

{
  "files.exclude": {
    "amplify/.config": true,
    "amplify/**/*-parameters.json": true,
    "amplify/**/amplify.state": true,
    "amplify/**/transform.conf.json": true,
    "amplify/#current-cloud-backend": true,
    "amplify/backend/amplify-meta.json": true,
    "amplify/backend/awscloudformation": true,
    "**/.git": true,
    "**/.DS_Store": true,
    "**/*.js": {
      "when": "$(basename).ts"
    },
    "**/*.d.ts": {
      "when": "$(basename).ts"
    }
  },
  "deepscan.enable": true,
  "editor.codeActionsOnSave": {
    "source.fixAll.markdownlint": true,
    "source.fixAll.eslint": true
  }
}

to (commenting out the causative issue)

{
  "files.exclude": {
    "amplify/.config": true,
    "amplify/**/*-parameters.json": true,
    "amplify/**/amplify.state": true,
    "amplify/**/transform.conf.json": true,
    "amplify/#current-cloud-backend": true,
    "amplify/backend/amplify-meta.json": true,
    "amplify/backend/awscloudformation": true,
    "**/.git": true,
    "**/.DS_Store": true,
    // "**/*.js": {
    //   "when": "$(basename).ts"
    // },
    // "**/*.d.ts": {
    //   "when": "$(basename).ts"
    // }
  },
  "deepscan.enable": true,
  "editor.codeActionsOnSave": {
    "source.fixAll.markdownlint": true,
    "source.fixAll.eslint": true
  }
}

[rjmholt]

I've finally tracked down the definition of this expression syntax. As far as I know it's still undocumented and it's not clear how stable this is intended to be, but we might at least be able to implement something around it given this information.

[TylerLeonhardt]

It's a stable API. It's just... unfortunately... not documented.

[haugerbr]

It's documented here on the official VSCode docs. Unless we are talking about it being documented somewhere else?

[andyleejordan]

The fix for this is out in PowerShell Preview v2022.2.2!
