[X] If this is a security issue, I have read the security issue reporting guidance.

Summary

In Visual Studio Code with the PowerShell extension installed, placing the cursor inside a param(...) block in or next to a parameter (variable) declaration and calling Find-Ast -AtCursor doesn't recognize the cursor location as a System.Management.Automation.Language.ParameterAst instance and instead returns the entire script (System.Management.Automation.Language.NamedBlockAst)

It currently only works in inline parameter declarations of functions.

PowerShell Version

PowerShell 7.4.0

Editor Version

Visual Studio Code 1.85.1

PowerShell Editor Services Version

3.13.0

Steps to Reproduce

Using the PIC (PowerShell Integrated Console) in Visual Studio code with psedit $PROFILE, add the following code to $PROFILE (and ensure that profile loading is enabled):

function Rename-Variable {
  param($Context)

  $variable = Find-Ast -AtCursor
  $variable.GetType().Fullname | Write-Verbose -Verbose
}

Then add F2 as a keybinding, via keybindings.json:

{
  "key": "F2",
  "command": "PowerShell.InvokeRegisteredEditorCommand",
  "args": {
    "commandName": "Rename-Variable"
  },
  "when": "editorLangId == 'powershell' && editorTextFocus"
}

Start a new session, and create a PowerShell script file with the following content:

param(
  [string] $Foo
)

Place the cursor in the middle of $Foo and press F2

You should see System.Management.Automation.Language.ParameterAst, but currently get System.Management.Automation.Language.NamedBlockAst
