使用grunt，是否可以编译和输出单个更改的文件到不同的目录？ [英] using grunt, is it possible to compile and output a single changed file to a different directory?

问题描述

/ assets / src / coffee 等中的许多咖啡源文件（ ./ child / paths 等） ），我想将它们输出到 assets / js / 和 assets / js / child / paths 。

Many coffee source files in /assets/src/coffee etc (./child/paths and so on) and I'd like to output them to assets/js/ and assets/js/child/paths.

看起来我已经接近，但它不工作。使用 grunt-contrib-coffee 和 grunt-contrib-watch 。

It looks like I've gotten close, but it's not working. Using grunt-contrib-coffee and grunt-contrib-watch.

grunt.initConfig
watch:
  coffee:
    files: '<%= coffee.src %>',
    tasks: 'coffee:dev'
    options:
      nospawn: true

coffee:
  src: 'assets/src/coffee/**/*.coffee'
  dev:
    options:
      sourceMap: true
    files: [
      expand: true
      cwd: "assets/"
      src: "/src/coffee/**/*.coffee"
      dest: "../js/"
      ext: ".js"
    ]

grunt.loadNpmTasks "grunt-contrib-coffee"
grunt.loadNpmTasks 'grunt-contrib-watch' 
# Default task.
grunt.registerTask "default", "watch"

grunt.event.on('watch', (action, filepath) ->
(grunt.log.writeln('\n'+ filepath + ' has ' + action))

dest = "#{path.dirname(filepath.replace("src/coffee", "js"))}"

grunt.config(['coffee', 'dev', 'files', 'src'], [filepath])
grunt.config(['coffee', 'dev', 'files', 'dest'], [dest])

(grunt.log.writeln("src: #{grunt.config(['coffee', 'dev', 'files', 'src'])}"))
(grunt.log.writeln("dest: #{grunt.config(['coffee', 'dev', 'files', 'dest'])}"))

）

其输出如下：

assets/src/coffee/projAlpha/dl.coffee has changed    
src: assets/src/coffee/projAlpha/dl.coffee    
dest: assets/js/projAlpha/dl.coffee

但文件实际上最终在： assets / src / coffee / projAlpha / dl.coffee ...和它的咖啡脚本。它应该在 assets / js / projAlpha / dl.js 中。

but the file actually ends up in: assets/src/coffee/projAlpha/dl.coffee... and it's coffee script. It should be in assets/js/projAlpha/dl.js.

我已经得到了grunt coffee工具来编译所有文件，并将它们放在正确的位置。我宁愿他们一次编译一个，虽然，因为我现在有几个文件，并添加更多的时间。

I've gotten the grunt coffee utility to compile all the files at once and put them in the right place. I'd rather they got compiled one at a time though, since I've got a few files now and am adding more all the time.

推荐答案

在您的glob模式文件路径配置中，我注意到两个问题：

In your glob-pattern file path config, I notice 2 problems:

1. glob模式选项不在文件键下，而是直接在选项键下的
   。


2. CWD只适用于src文件。 dest目录不
   使用cwd，因此必须从基本目录
   （您的Gruntfile所在的位置）指定完整路径。

dev:
  options:
    sourceMap: true
  expand: true
  cwd: "assets/src/coffee/"
  src: "**/*.coffee"
  dest: "assets/js/"
  ext: ".js"

这将移动，例如 assets / src / coffee / User / controller .coffee 到 assets / js / User / controller.js 。
