解析脚本永不结束

Question

我有以下脚本，但它永远不会结束执行。

可能是什么问题？我试图调试它，但显然它可以正确使用单个文件，但是当我将它扔到内容充满内容的文件夹失败时。

$path = split-path -parent $MyInvocation.MyCommand.Definition 
$files = Get-ChildItem "$path\CodeForCertification\5_SourceCode\*" -Include *.c,*.h -Recurse | where{ 
     ! $_.PSIsContainer 
}#$PSScriptRoot 

ForEach ($file in $files){ 

    $data = Get-Content -Path $file.FullName 
    $feature = Get-Content "$path\Disabled_Features.txt"  
    #[System.ArrayList]$Modifier 
    $nl=[Environment]::NewLine 
    $Modifier=@() 
    $flag=0 
    $data = $data | ForEach-Object -Begin { 
     $ignore = $false; $levels = 0 
    } -Process { 
     for($counter=0; $counter -lt $feature.Count; $counter++){ 
      $parse = $feature[$counter] 
      if($_ -match "^#ifdef $parse" -And $flag -eq '0') { 
       $ignore = $true 
       $flag = 1; 
      } 
     } 
     if($ignore) { 
      if ($_ -match "^#ifdef") { 
       $levels++ 
      }elseif ($_ -match "#endif") { 
       if($levels -ge 1) { 
        $levels-- 
        if($levels -eq '0'){ 
         $ignore = $false 
        }       
       } 
      } 
     }else { 
      $flag=0 
      $temp=$_ 
      $_ 
      $Modifier+="$temp" 
     } 
    } 
    $data | Out-File $file.FullName 
}

OK，杰克逊，让我们来解决你的问题，你进入了某种问题的垃圾邮件过滤;-)的

考虑这个（只是把它放在你的脚本的开始）前：

function RemoveUndesiredFeatures([string[]]$lines,[string[]]$undesiredFeatures) 
{  
    $inIgnoreBlock = $false 
    $nestingLevel = 0 

    foreach ($line in $lines) 
    { 
     if ($inIgnoreBlock) 
     { 
      # Only search for nested blocks and end of block 
      if ($line -like "#ifdef*") 
      { 
       $nestingLevel++ 
      } 
      elseif ($line -like "#endif*") 
      { 
       $nestingLevel-- 
      } 

      if ($nestingLevel -eq 0) 
      { 
       $inIgnoreBlock = $false 
      } 
     } 
     else 
     { 
      # Search for undesired feature 
      $isIfdefMatch = $line -match "#ifdef (?<feature>\w+)" 

      if ($isIfdefMatch -and ($Matches.feature -in $undesiredFeatures)) 
      { 
       # Ignore Feature 
       $inIgnoreBlock = $true 
       $nestingLevel++ 
      } 
      else 
      { 
       # Output line 
       $line 
      } 
     }  
    } 
} 

这里是我的例子中使用它？

$undesiredFeatures = @("F1","F2") # Just as example. Get-Content on a file with features is also fine 

$files = Get-ChildItem *.c,*.h -Recurse # Again, just as example 

foreach ($file in $files) 
{ 
    $lines = Get-Content $file.FullName 

    $changedLines = RemoveUndesiredFeatures $lines $undesiredFeatures 

    if ($changedLines.Count -ne $lines.Count) 
    { 
     # Features were removed. Write out changed file (to a different file to preserve my test files) 
     Set-Content -Value $changedLines -Path "$($file.FullName).changed" 
    } 
}
