我只想在我保存的单个文件上运行coffee lint和coffee compile。我的项目中有成百上千个CoffeeScript文件,而编译它们都需要太多时间。
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。
即使grunt表示运行,coffee编译也不产生任何JS文件。
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

怎么了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:
force: true
all:
expand: true
cwd: 'src/coffeescript/'
src: '**/*.coffee'
modified:
expand: true
cwd: 'src/coffeescript/'
src: '**/*.coffee'
filter: isModified
watch:
coffeescript:
files: ['src/**/*.coffee']
tasks: ['coffeelint:modified', 'coffee:modified']
grunt.loadNpmTasks 'grunt-coffeelint'
grunt.loadNpmTasks 'grunt-contrib-coffee'
grunt.loadNpmTasks 'grunt-contrib-watch'
grunt.registerTask 'default', ['coffeelint:all', 'coffee:all', 'watch']
最佳答案
尝试在您的c任务中添加类似的内容
coffee:
all:
filter: (filepath) ->
fs = require('fs')
now = new Date()
modified = fs.statSync(filepath).mtime
return (now - modified) < 10000 # or another difference in millyseconds
