如何运行“颜色” NAnt 脚本中的命令

Question

我刚刚开始使用 Nant 进行构建和测试。我想让它在失败时更改命令提示符文本的颜色（或背景），以便很容易注意到。

Windows 上命令提示符中的命令是“color 4”，将其更改为红色，“color 7”将其更改回白色。

我如何使其在构建脚本中运行，echo 不起作用，exec 不起作用（尽管可能使用了 exec 错误）。我宁愿不必运行 perl 等，只是为了做一些在标准命令提示符窗口中轻松完成的事情。

有谁知道该怎么做？

Answer 1

尝试使用自定义任务。如果该任务包含在 nant 文件中，您将不会有任何外部依赖项。

<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>

作为我对 @Martin-Vobr 帖子的评论的后续：

我添加了额外的逻辑来正确更改背景。这将允许在命令窗口中启动构建，然后可以一目了然地检查进度。我使用蓝色背景表示“构建”，绿色表示“成功”，红色表示“失败”。
