[英]grunt task with custom json config
i want to create some kind of task where i can read custom configs from different json files, and replace stuff inside my coffee-source files with contents of the json files, and concatenate the source-files. 我想创建某种任务,我可以从不同的json文件中读取自定义配置,并用我的咖啡源文件中的内容替换json文件的内容,并连接源文件。
my projekt-setup: 我的projekt设置:
./src ./src
./config ./config中
/folder1 /资料夹
/folder2 /资料夹
./dist ./dist
file1.coffee contains file1.coffee包含
myVar = '@@putkeyhere'
version = '@@version'
...
i have the grunt concat task running for itself configured and working: 我有自己配置和工作的grunt concat任务:
concat: {
dist: {
src: ['<banner>', './src/*.coffee'],
dest: './dist/<%= pkg.name %>.coffee'
}
},
i have got the grunt-replace task (the replacement of version and so on is already working when i run "grunt replace" on already concatenated files) 我有grunt-replace任务(当我在已经连接的文件上运行“grunt replace”时,替换版本等已经工作了)
replace: {
dist: {
options: {
variables: {
'created': '<%= grunt.template.today("dd.mm.yyyy HH:MM:ss") %>',
'environment': 'dev',
'version': '<%= pkg.version %>'
},
prefix: '@@'
},
files: {
'dist/': ['./dist/<%= pkg.name %>.coffee']
}
}
},
and finally the coffee compile task: 最后咖啡编译任务:
coffee: {
compile: {
files: {
'./dist/<%= pkg.name %>.js': ['./dist/*.coffee']
}
}
}
all tasks work for themselves, but i need to read from the config-json files replace the contents into concatenated coffee-files, and then compile all files to js. 所有任务都适合自己,但我需要从config-json文件中读取内容替换为连接的咖啡文件,然后将所有文件编译为js。
i tried something like this, but that doesnt feel right: 我试过这样的事,但感觉不对:
grunt.registerTask('mytask', '', function (env) {
env = env || 'development';
if (env !== 'development' && env !== 'production') {
grunt.log.error("'" + env + "' is not valid environment");
return false;
}
var c = grunt.option('c');
if(c) {
// if i run the task "grunt mytask:production -c folder2 it should read
// ./config/folder2/development.json
// that works that way, but i dont think this is a good solution
var config = grunt.file.readJSON('./config/' + c + '/' + env + '.json')
} else {
// here i need to iterate for all folders in ./config, and do stuff for all
}
});
is the multiTask an option? multiTask是一个选项吗? but how do read dynamically from the config.json files?
但如何从config.json文件中动态读取?
