Issue Description

Create a PowerShell file, input following script, and hit Alt+Shift+F. The file is not formatted.

    $a = [pscustomobject]@{
        a=1
      b=2
    }
            $a|Select-Object  a,b

Related settings in settings.json:

    "powershell.codeFormatting.trimWhitespaceAroundPipe": true,
    "powershell.codeFormatting.useCorrectCasing": true,
    "powershell.codeFormatting.whitespaceBetweenParameters": true,

Expected Behaviour

The format result should look similar to:

$a = [pscustomobject]@{
    a = 1
    b = 2
}
$a | Select-Object -Property a, b

Actual Behaviour

The file is unchanged.

Here are some other input/output combinations if I change the script a little bit and hit Alt+Shift+F again:

• Case 1 -- looks well except that the space is removed in a, b.
  • Input:

      $a = [pscustomobject]@{
          a=1
        b=2
      }
              $a|Select-Object  a, b
  

  • Output:

  $a = [pscustomobject]@{
      a = 1
      b = 2
  }
  $a | Select-Object a,b
  

• Case 2 -- the necessary comma , is removed in a ,b, which makes the code invalid.
  • Input:

      $a = [pscustomobject]@{
          a=1
        b=2
      }
              $a|Select-Object  a ,b
  

  • Output:

  $a = [pscustomobject]@{
      a = 1
      b = 2
  }
  $a | Select-Object a b
  

• Case 3 -- the space is removed in a, b.
  • Input:

  $a = [pscustomobject]@{
      a = 1
      b = 2
  }
  $a | Select-Object a, b
  

  • Output:

  $a = [pscustomobject]@{
      a = 1
      b = 2
  }
  $a | Select-Object a,b
  

• Case 4 -- this is the reverse of Case 3. If I keep hitting Alt+Shift+F, the file will cycle through Case 3 and 4.
  • Input:

  $a = [pscustomobject]@{
      a = 1
      b = 2
  }
  $a | Select-Object a,b
  

  • Output:

  $a = [pscustomobject]@{
      a = 1
      b = 2
  }
  $a | Select-Object a, b
  

在 PowerShell 檔案中使用 Alt+Shift+F，搭配以逗號分隔的參數和列出的程式碼格式設定來重現此問題。將格式化程式的輸出與預期範例進行比較，包括保留 a, b 中的逗號和空格；當格式化穩定且程式碼仍然有效時，即表示完成。
