我想只在我保存的单个文件上运行咖啡棉绒和咖啡编译。我的项目中有数百个 CoffeeScript 文件,编译所有这些文件需要太多时间。
这是我的 Gruntfile:
module.exports = (grunt) ->
grunt.initConfig
pkg: grunt.file.readJSON 'package.json'
coffee:
all:
expand: true
bare: true
cwd: 'src/coffeescript/'
src: '**/*.coffee'
dest: 'public/js/compiled'
ext: '.js'
coffeelint:
all: ['src/coffeescript/**/*.coffee']
watch:
coffeescript:
files: ['src/**/*.coffee']
tasks: ['coffeelint', 'coffee']
options:
spawn: false
grunt.event.on 'watch', (action, filepath) ->
grunt.config(['coffeelint', 'all'], filepath)
grunt.config(['coffee', 'all'], filepath)
grunt.loadNpmTasks 'grunt-coffeelint'
grunt.loadNpmTasks 'grunt-contrib-coffee'
grunt.loadNpmTasks 'grunt-contrib-watch'
grunt.registerTask 'default', ['coffeelint', 'coffee', 'watch']
Coffeelint 任务仅在更改的文件上成功运行。
咖啡编译不会产生任何 JS 文件,即使 grunt 说它运行。
这是保存单个咖啡文件后的输出:
OK
>> File "src/coffeescript/app.coffee" changed.
Running "coffeelint:all" (coffeelint) task
>> 1 file lint free.
Running "coffee:all" (coffee) task
Running "watch" task

这里有什么问题?任何帮助将不胜感激!
更新:
这是一个工作示例:
module.exports = (grunt) ->
fs = require 'fs'
isModified = (filepath) ->
now = new Date()
modified = fs.statSync(filepath).mtime
return (now - modified) < 10000
grunt.initConfig
coffee:
options:
sourceMap: true
bare: true
force: true # needs to be added to the plugin
all:
expand: true
cwd: 'src/coffeescript/'
src: '**/*.coffee'
dest: 'public/js/compiled'
ext: '.js'
modified:
expand: true
cwd: 'src/coffeescript/'
src: '**/*.coffee'
dest: 'public/js/compiled'
ext: '.js'
filter: isModified
coffeelint:
options:

watch:
