监控 grunt-contrib-watch 的子任务

Question

我有以下 Gruntfile.coffee。我正在监视监视任务，如下所示以查看文件更改，然后将更改的文件编译为咖啡脚本。

# Watch task
watch:
 coffee:
  files: ['client/**/*.coffee','server/**/*/.coffee']
  options:
   nospawn: true
   livereload: true

# Watch changed files
grunt.event.on 'watch', (action, filepath) ->
 cwd = 'client/'
 filepath = filepath.replace(cwd,'')
 grunt.config.set('coffee',
  changed:
   expand: true
   cwd: cwd
   src: filepath
   dest: 'client-dist/'
   ext: '.js'
 )
 grunt.task.run('coffee:changed')

但是，我想添加另一个监视任务来复制不是咖啡文件的文件。我将如何监控这些变化？

我想过做

# Watch copy task
grunt.event.on 'watch:copy', (action,filepath) -> ...
# Watch coffee task
grunt.event.on 'watch:coffee', (action,filepath) -> ...

但这似乎不起作用。想法？

Answer 1

我的解决方案 - 完成了工作，但并不漂亮。我欢迎更好的答案

基本上，我匹配传入文件的路径
如果它的 .coffee 运行咖啡编译任务
如果它的 .* 运行复制任务

# Watch changed files
grunt.event.on 'watch', (action, filepath) ->

 # Determine server or client folder
 path = if filepath.indexOf('client') isnt -1 then 'client' else 'server'
 cwd = "#{path}/"
 filepath = filepath.replace(cwd,'')        

 # Minimatch for coffee files
 if minimatch filepath, '**/*.coffee'
  # Compile changed file
  grunt.config.set('coffee',
   changed:
    expand: true
    cwd: cwd
    src: filepath
    dest: "#{path}-dist/"
    ext: '.js'
  )
  grunt.task.run('coffee:changed')  

 # Minimatch for all others
 if minimatch filepath, '**/*.!(coffee)'
  # Copy changed file
  grunt.config.set('copy',
   changed:
    files: [
     expand: true
     cwd: cwd
     src: filepath
     dest: "#{path}-dist/"                      
    ]
  )
  grunt.task.run("copy:changed")

看一下观察事件示例底部的注释：https://github.com/gruntjs/grunt-contrib-watch#using-the-watch-event

watch 事件并非旨在替换 Grunt API。请改用tasks：

watch:
  options:
    nospawn: true
    livereload: true
  coffee:
    files: ['client/**/*.coffee','server/**/*/.coffee']
    tasks: ['coffee']
  copy:
    files: ['copyfiles/*']
    tasks: ['copy']
