我希望能够在我的主项目中拥有不同的子项目。例如:
-- my-project/
- Gruntfile.js
- subproject1/
- index.html
- scss/
- main.scss
- subproject2/
- index.html
- scss/
- main.scss
我希望能够在不触发子项目2任务的情况下修改子项目1中的文件。
截至目前,我正在配置我的gruntfile,如下所示:
watch: {
subproject1: {
files: ['subproject1/*.html', 'subproject1/scss/**/*.scss'],
tasks: ['sass', 'premailer:subproject1']
},
subproject2: {
files: ['subproject2/*.html', 'subproject2/scss/**/*.scss'],
tasks: ['sass', 'premailer:subproject2']
}
},
premailer: {
subproject1: {
options: {
css: 'subproject1/css/main.css',
verbose: false
},
files: [
{
'subproject1/dist/index.html' : 'subproject1/index.html'
}
]
},
subproject2: {
options: {
css: 'subproject2/css/main.css',
verbose: false
},
files: [
{
'subproject2/dist/index.html' : 'subproject2/index.html'
}
]
},
}
有没有办法根据修改的文件动态指定grunt要运行的任务(例如,我修改文件夹 /index.html,然后运行premailer:文件夹 )或者这是实现它的唯一方法吗?
答案 0 :(得分:1)
您可以使用grunt.file方法(docs here)检查Gruntfile中主文件夹中的所有文件夹,创建子项目名称数组,然后使用forEach动态创建任务。
这样的事情应该去:
/*global module:false*/
module.exports = function(grunt) {
var mycwd = "./";
var tempFileList = grunt.file.expand(
{ filter: function (src) {
if (grunt.file.isDir(src) == true) {
return true;
}
return false;
} },
[ mycwd + "!(Gruntfile.js|node_modules|package.json)" ] // structure to analyse
);
// I create an empty array to put all elements in, once cleaned.
var fileList = [];
tempFileList.forEach(function(url){
var cwd = url;
cwd = cwd.replace(mycwd, "");
fileList.push(cwd);
})
var watchObject = {};
var premailerObject = {};
fileList.forEach(function(name) {
watchObject[name] = {
files: [name + '/*.html', name + '/scss/**/*.scss'],
tasks: ['sass', 'premailer:' + name]
};
var filesObject = {};
filesObject[name+'/css/main.css'] = name + '/index.html';
premailerObject[name] = {
options: { css: name + '/css/main.css', verbose: false },
files: [ filesObject ]
};
});
var configObject = {
watch: watchObject,
premailer: premailerObject
};
// just to check the final structure
console.log(configObject);
grunt.initConfig(configObject);
};
