Formatting fails to pretty print a bad formatted document

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been reported.

Summary

I have some code copied from a pdf. Here it is when I paste it in VSCode :

function Stop-ProcessUsingWMI{    [CmdletBinding(SupportsShouldProcess=$True)]    param(      [parameter(mandatory=$true)] [regex] $pattern    )    foreach ($process in Get-WmiObject Win32_Process |        where { $_.Name -match $pattern })    {        if ($PSCmdlet.ShouldProcess(            "process $($process.Name) " +            " (id: $($process.ProcessId))" ,            "Stop Process"))        {            $process.Terminate()        }    }}

A long one-line code.

After formatting it, I get this :

function Stop-ProcessUsingWMI {
	[CmdletBinding(SupportsShouldProcess = $True)]    param(      [parameter(mandatory = $true)] [regex] $pattern    )    foreach ($process in Get-WmiObject Win32_Process | Where-Object { $_.Name -match $pattern }) {
		if ($PSCmdlet.ShouldProcess(            "process $($process.Name) " + " (id: $($process.ProcessId))" , 'Stop Process')) {
			$process.Terminate()        
		}    
	}
}

It is better but far from what one could expect from a well formatted code. There are multiple spaces everywhere and function body is not standard. Here is what I would expect :

function Stop-ProcessUsingWMI {
	[CmdletBinding(SupportsShouldProcess = $True)]
	param(
		[parameter(mandatory = $true)] [regex] $pattern 
	)
	
	foreach ($process in Get-WmiObject Win32_Process | Where-Object { $_.Name -match $pattern }) {
		if ($PSCmdlet.ShouldProcess( "process $($process.Name) " + " (id: $($process.ProcessId))" , 'Stop Process')) {
			$process.Terminate() 
		} 
	}
}

PS extension custom settings :

	"powershell.buttons.showPanelMovementButtons": true,
	"powershell.codeFormatting.autoCorrectAliases": true,
	"powershell.codeFormatting.preset": "OTBS",
	"powershell.codeFormatting.trimWhitespaceAroundPipe": true,
	"powershell.codeFormatting.useCorrectCasing": true,
	"powershell.integratedConsole.focusConsoleOnExecute": false,
	"powershell.codeFormatting.useConstantStrings": true,
	"security.workspace.trust.untrustedFiles": "open",
	"editor.suggest.preview": true,
	"powershell.codeFormatting.ignoreOneLineBlock": false,
	"powershell.codeFormatting.whitespaceBetweenParameters": true

Proposed Design

• remove multiple spaces when not needed
• format function body, list of parameters and attributes on their respected line.

使用提供的 PowerShell 函式和列出的 PSScriptAnalyzer 設定重現 issue 中的格式化結果。將輸出與預期範例進行比較，然後追蹤負責空白、函式主體、參數和屬性的格式化器行為。當格式錯誤的單行文件能夠像預期範例一樣進行格式化，且沒有不必要的重複空格時，即表示完成。
