如何在NAnt腳本中運行'color'命令

Question

我剛開始使用Nant進行構建和測試。當它失敗時，我想讓它改變我的命令提示符文本的顏色（或背景），因此很容易被注意到。

Windows上的命令提示符中的命令是「顏色4」，將其更改爲紅色，將顏色7更改爲白色。

如何在構建腳本中執行此操作，echo不起作用，exec不起作用（儘管可能會使用exec錯誤）。我寧願不必運行perl等只是做一些在標準命令提示符窗口中輕鬆完成的任務。

有誰知道如何做到這一點？

嘗試使用自定義任務。如果該任務包含在nant文件中，則不會有任何外部依賴關係。

<project > 

    <target name="color"> 
     <consolecolor color="Red" backgroundcolor="White"/> 
     <echo message="red text"/> 
     <consolecolor color="White" backgroundcolor="Black"/> 
     <echo message="white text"/> 
    </target> 

    <script language="C#"> 
     <code> 
      [TaskName("consolecolor")] 
      public class TestTask : Task 
      { 
      private string _color; 
      private string _backgroundColor; 

      [TaskAttribute("color",Required=true)] 
      public string Color 
      { 
      get { return _color; } 
      set { _color = value; } 
      } 

      [TaskAttribute("backgroundcolor",Required=false)] 
      public string BackgroundColor 
      { 
      get { return _backgroundColor; } 
      set { _backgroundColor = value; } 
      } 

      protected override void ExecuteTask() 
      { 
      System.Console.ForegroundColor = (System.ConsoleColor) Enum.Parse(typeof(System.ConsoleColor),Color); 
      System.Console.BackgroundColor = (System.ConsoleColor) Enum.Parse(typeof(System.ConsoleColor),BackgroundColor); 
      } 
      } 
     </code> 
    </script> 

</project>

作爲後續行動，以通過@馬丁 - Vobr我對發表的留言：

我已經添加了額外的邏輯來適當地改變背景。這將允許在命令窗口中啓動構建，然後一眼就可以檢查進度。 「建築」使用藍色背景，「成功」使用綠色，「失敗」使用紅色。
