我的站点文件结构是这样的:

app
    less
        themes
            default
            modern
            etc
public
    themes
        default
            css
        modern
            css
        etc


因此/app/less/themes/{{ themeName }}/*.less将编译为/public/themes/{{ themeName }}/css/*.css

我有动态设置的Grunt Less任务,并且工作正常。
示例:grunt less:compileTheme:modern

less: {
  compileTheme: {
    options: {
      compress: false,
      yuicompress: false,
      optimization: 2,
      sourceMap: true,
      sourceMapFilename: "public/themes/<%= grunt.task.current.args[0] %>/css/styles.css.map",
      sourceMapURL: "/themes/<%= grunt.task.current.args[0] %>/css/styles.css.map"
    },
    files: {
      "public/themes/<%= grunt.task.current.args[0] %>/css/styles.css": "app/less/themes/<%= grunt.task.current.args[0] %>/styles.less"
    }
  }
}


但是我不确定如何使Grunt Watch任务正常运行。理想情况下,它将看到主题文件夹名称,并以grunt less:compileTheme:{{ themeName }}的形式运行grunt任务:

watch: {
    themeCss: {
        files: "app/less/themes/{{ themeName }}/**/*.less",
        tasks: ["less:compileTheme:{{ themeName }}"],
        options: {
          spawn: false
        }
    }
}


这可能吗?和/或有没有更好的方法我应该这样做?

最佳答案

编辑监视任务以运行不带themeName的less:compileTheme -task,并监视主题文件夹中所有较少的文件:

watch: {
    themeCss: {
        files: "app/less/themes/**/*.less",
        tasks: ["less:compileTheme"],
        options: {
          spawn: false
        }
    }
}


现在,您可以添加一个监视事件处理程序,以获取更改后的文件。提取themeName,并配置您的较少任务:

grunt.event.on('watch', function(action, filepath) {
  var themeName = filepath.split('/')[3];
  grunt.config('less.compileTheme.files', {
    "public/themes/" + themeName + "/css/styles.css": "app/less/themes/" + themeName + "/styles.less"
  });
});


当然,对themeName的检测应该更可靠,但是我认为您对如何进行动态监视有了想法!
