Coffeescript 如何将grunt regarde与grunt contrib coffee一起使用，以仅编译更改的.coffee文件？

我的项目有300多个CoffeeScript文件，因此需要几秒钟来重新编译所有内容。我只想重新编译更改后的CoffeeScript文件

这是我到目前为止最接近的一个，但是“frontend src/coffeescript”文件夹结构正在从src目录复制到dest目录

coffee: {
  changed: {
    expand: true,
    cwd: './',
    src: ['<%= grunt.regarde.changed %>'],
    dest: 'public/js/',
    ext: '.js'
  }
},
regarde: {
  coffee: {
    files: 'frontend-src/coffeescript/**/*.coffee',
    tasks: ['coffee:changed', 'livereload']
  }
}

咖啡：{
更改：{
是的，
cwd:“./”，
src:['']，
dest:'public/js/'，
分机：'.js'
}
},
雷加德：{
咖啡：{
文件：“前端src/coffeescript/***.coffee”，
任务：[“咖啡：已更改”，“livereload”]
}
}

---

这就是Grunt0.4.0的全部内容。任何帮助都将不胜感激

grunt.regarde.changed

数组是否正确

应该

src:['']

be

src:“

我查看了一下grunt contrib咖啡的来源，看看它是否能正确处理您提供的任何东西。看起来有点像你给它的字符串化数组，没有被抓住和处理

我认为您无意中传递的可能是：

src:['[path1、path2、path3等]]

---

如果我偏离了正确的方向，请留下评论，我将删除此答案。

我自己也遇到过这个问题，我能够从对这个问题的评论中找到解决方案：

它实际上是用于grunt contrib watch插件的，但它也应该适用于grunt regarde，因为它有类似的事件

其思想是将回调绑定到

watch

事件，在该事件中，您使用更改的文件路径向grunt配置添加一个新任务，然后运行它

从我的

Gruntfile.coffee

：

coffee:
    app:
        expand: true
        cwd: 'app/'
        src: ['*.coffee',"**/*.coffee"]
        dest: './public/temp'
        ext: '.js'
watch: 
    coffee:
        files: ['app/**/*.coffee']
        tasks: ['livereload']
        options:
            nospawn: true

grunt.event.on 'watch', (action, filepath) ->       
    cwd = 'app/'
    filepath = filepath.replace(cwd,'')
    grunt.config.set('coffee',
        changed:
            expand: true
            cwd: cwd
            src: filepath
            dest: './public/temp'
            ext: '.js'
    )
    grunt.task.run('coffee:changed')

---

nospawn对于watch任务很重要，因此它在livereload任务之前运行新任务。我很确定regarde默认情况下不会生成子进程。

我也遇到过同样的问题。我使用

regarde:file

事件解决了这个问题

首先，我通过使用

regarde:file

事件来侦听已更改的文件。这将为两个任务提供配置：

clean:coffee

如果源位置中的文件已被删除，以及

coffee:refresh

如果文件已被更改/添加

然后，

regarde

任务将触发其任务，该任务将启动

refresh:coffee

（不要被

coffee:refresh

搞错）。此任务将检查是否为

clean:coffee

和/或

coffee:refresh

添加了配置，并在需要时运行这些任务（通过函数

grunt.task.run

）。If还将重置标志，这将导致下一个收到的

regarde:file

事件再次清理配置

深入解释：

grunt.event.on('regarde:file', function (status, target, filepath) {
   if (resetFlag) {
      // clean file list from previous cycle, so clean clean:coffee and coffee:refresh
      // file lists
      ...

      resetFlag = false;
   } 
   if (status === 'deleted') {
        if (filepath) {
            // calculate filepath's destination and  
            // add it to clean:coffee filelist
        }
    } else {
        if (!grunt.file.isDir(filepath)) {
            // add filepath to coffee:refresh filelist
        }
    }
}

var config = grunt.config('coffee') || {};
var value = config.refresh || {};
value.files = value.files || [];
...
var cwd = path.dirname(filepath),
    src = path.basename(filepath),
    dest = cwd.replace('path/to/source', 'path/to/dest');
    value.files.push({
       expand:true,
       src:src,
       dest:dest,
       cwd:cwd,
       ext:'.js'
    });
grunt.config('coffee', config);

    var cwd = path.dirname(filepath),
        src = path.basename(filepath),
        dest = cwd.replace('path/to/source', 'path/to/dest');
        value.src.push(path.join(dest, src.replace('coffee', 'js')));
    // clean only what has been removed
        config = grunt.config('clean') || {};

    config.coffee = value;

    grunt.config('clean', config);

    grunt.registerMultiTask('refresh', 'refreshing the changed file(s)', function () {
        this.requires('regarde');

        var tasks = [];
        var clean = grunt.config('clean');

        // check if there is clean:refresh config available
        if (clean && clean[this.target]) {
            tasks.push('clean:' + this.target);
        }
        var config = grunt.config(this.target);

        // check if there is coffee:refresh config available
        if (config && config.refresh) {
            tasks.push(this.target + ':refresh');
        }
        // run the tasks
        grunt.task.run(tasks);

        // set the resetFlag back to true
        resetFlag = true;
    });

首先，

regarde

config：

 // watch for changed coffeescript files
 coffee: {
    files: 'path/to/coffee/**/*.coffee',
    tasks: ['refresh:coffee', 'livereload']
 },

然后我监听

regarde:file

事件，在其中我更新配置中的

clean:coffee

和

coffee:refresh

文件列表

根据

regarde:file

事件：

grunt.event.on('regarde:file', function (status, target, filepath) {
   if (resetFlag) {
      // clean file list from previous cycle, so clean clean:coffee and coffee:refresh
      // file lists
      ...

      resetFlag = false;
   } 
   if (status === 'deleted') {
        if (filepath) {
            // calculate filepath's destination and  
            // add it to clean:coffee filelist
        }
    } else {
        if (!grunt.file.isDir(filepath)) {
            // add filepath to coffee:refresh filelist
        }
    }
}

var config = grunt.config('coffee') || {};
var value = config.refresh || {};
value.files = value.files || [];
...
var cwd = path.dirname(filepath),
    src = path.basename(filepath),
    dest = cwd.replace('path/to/source', 'path/to/dest');
    value.files.push({
       expand:true,
       src:src,
       dest:dest,
       cwd:cwd,
       ext:'.js'
    });
grunt.config('coffee', config);

    var cwd = path.dirname(filepath),
        src = path.basename(filepath),
        dest = cwd.replace('path/to/source', 'path/to/dest');
        value.src.push(path.join(dest, src.replace('coffee', 'js')));
    // clean only what has been removed
        config = grunt.config('clean') || {};

    config.coffee = value;

    grunt.config('clean', config);

    grunt.registerMultiTask('refresh', 'refreshing the changed file(s)', function () {
        this.requires('regarde');

        var tasks = [];
        var clean = grunt.config('clean');

        // check if there is clean:refresh config available
        if (clean && clean[this.target]) {
            tasks.push('clean:' + this.target);
        }
        var config = grunt.config(this.target);

        // check if there is coffee:refresh config available
        if (config && config.refresh) {
            tasks.push(this.target + ':refresh');
        }
        // run the tasks
        grunt.task.run(tasks);

        // set the resetFlag back to true
        resetFlag = true;
    });

通过

grunt.config（）

函数很容易更新配置。下面是要输入的代码片段

coffee:refresh

和

clean:coffee

将配置添加到

咖啡：刷新
：

grunt.event.on('regarde:file', function (status, target, filepath) {
   if (resetFlag) {
      // clean file list from previous cycle, so clean clean:coffee and coffee:refresh

      ...

      resetFlag = false;
   } 
   if (status === 'deleted') {
        if (filepath) {
            // calculate filepath's destination and  
            // add it to clean:coffee filelist
        }
    } else {
        if (!grunt.file.isDir(filepath)) {
            // add filepath to coffee:refresh filelist
        }
    }

var config = grunt.config('coffee') || {};

    });
grunt.config('coffee', config);

    var cwd = path.dirname(filepath),
        src = path.basename(filepath),
        dest = cwd.replace('path/to/source', 'path/to/dest');
        value.src.push(path.join(dest, src.replace('coffee', 'js')));
    // clean only what has been removed
        config = grunt.config('clean') || {};

    config.coffee = value;

    grunt.config('clean', config);

    grunt.registerMultiTask('refresh', 'refreshing the changed file(s)', function () {
        this.requires('regarde');

        var tasks = [];
        var clean = grunt.config('clean');

        // check if there is clean:refresh config available
        if (clean && clean[this.target]) {
            tasks.push('clean:' + this.target);
        }
        var config = grunt.config(this.target);

        // check if there is coffee:refresh config available
        if (config && config.refresh) {
            tasks.push(this.target + ':refresh');
        }
        // run the tasks
        grunt.task.run(tasks);

        // set the resetFlag back to true
        resetFlag = true;
    });

将配置添加到

      resetFlag = false;
   } 
   if (status === 'deleted') {
        if (filepath) {
            // calculate filepath's destination and  
            // add it to clean:coffee filelist
        }
    } else {
        if (!grunt.file.isDir(filepath)) {
            // add filepath to coffee:refresh filelist

grunt.config('coffee', config);

对我有用（需要用字符串包装）。谢谢，我在上面更改了它。
