調査の方向性

powershell.codeFormatting.whitespaceBetweenParameters と powershell.codeFormatting.alignPropertyValuePairs を有効にした状態で、issue にある複数行の hashtable の例を使って警告を再現します。まず、拡張機能が PSScriptAnalyzer の PSAlightAssignmentStatement CheckHashtable オプションと PSUseConsistentWhitespace IgnoreAssignmentOperatorInsideHashTable オプションをどのように処理しているかを追跡します。両方の設定を有効にしたとき、演算子の後に 1 つのスペースを置いた整列済みの hashtable 代入で、競合する警告が発生しなければ完了です。

説明

Issue-Bug Needs: Triage
Prerequisites
  • I have written a descriptive issue title.
  • I have searched all open and closed issues to ensure it has not already been reported.
  • I have read the troubleshooting guide.
  • I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
  • I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.
  • If this is a security issue, I have read the security issue reporting guidance.
Summary

When having both powershell.codeFormatting.whitespaceBetweenParameters and powershell.codeFormatting.alignPropertyValuePairs enabled in the extension settings, the editor UI will always show the warning for one or the other. So multi-line hashtable assignments always have a yellow warning line under all of the key-value pairs, except the one that has the longest key-string.

In PSScriptAnalyzer, there is an option in the arguments for each of the two rules:
for PSAlightAssignmentStatement, there's CheckHashtable
for PSUseConsistentWhitespace there's IgnoreAssignmentOperatorInsideHashTable

If both of these respective options are enabled, the hashtable assignments receive no warnings when the = operators are aligned and there's only 1 space after.

The PowerShell VSCode extension should either detect when the two settings are enabled and enable the respective arguments automatically or offer the option to enable or disable the respective arguments if the settings are enabled so that multi-line hashtable assignments don't always receive warnings.

Steps to Reproduce

In VSCode Settings, enable both powershell.codeFormatting.whitespaceBetweenParameters and powershell.codeFormatting.alignPropertyValuePairs, then create a simple hashtable with multiple key-value pairs that have different legths of key-strings.

With Alignment:

$myHashtable = @{
    KeyOne   = 'item' # <- Warning: Use space before and after binary and assignment operators.
    Key2     = $aVariable # <- Warning: Use space before and after binary and assignment operators.
    KeyThree = 'ThirdValue' # <- No warning
    KeyFour  = $otherVariable # <- Warning: Use space before and after binary and assignment operators.
}
return @{
    Item1     = $false # <- Warning: Use space before and after binary and assignment operators.
    ItemTwo   = 2 # <- Warning: Use space before and after binary and assignment operators.
    ItemThree = $true # <- No warning
}

Without Alignment:

$myHashtable = @{
    KeyOne = 'item' # <- Warning: Assignment statements are not aligned.
    Key2 = $aVariable # <- Warning: Assignment statements are not aligned.
    KeyThree = 'ThirdValue' # <- No warning
    KeyFour = $otherVariable # <- Warning: Assignment statements are not aligned.
}
$myHashtable
return @{
    Item1 = $false # <- Warning: Assignment statements are not aligned.
    ItemTwo = 2 # <- Warning: Assignment statements are not aligned.
    ItemThree = $true # <- No warning
}
