我仍然无法为此找到可接受的解决方案,但现在有一个可行的解决方案:
Gruntfile.js 片段:
useminPrepare: {
html: ['<%= yeoman.app %>/index.html', '<%= yeoman.app %>/includes.html'],
options: {
dest: '<%= yeoman.dist %>',
flow: {
// i'm using this config for all targets, not only 'html'
steps: {
// Here you define your flow for your custom block
cssQuoted: ['concat', 'cssmin'],
// use the option below where you have minified files that you just want to concatenate
concatjs: ['concat'],
// Note that you NEED to redefine flow for default blocks...
// These below is default flow.
js: ['concat', 'uglifyjs'],
css: ['concat', 'cssmin']
},
// also you MUST define 'post' field to something not null
post: {}
}
}
},
usemin: {
//css_name: ['<%= yeoman.dist %>/{,*/}*.html'],
html: ['<%= yeoman.dist %>/{,*/}*.html'],
css: ['<%= yeoman.dist %>/styles/{,*/}*.css'],
options: {
//patterns: {
// html: [
// [ /cssHrefString\s+=\s+['"]([^"']+)["']/gm, 'Update the HTML to reference our revved/min CSS and add quotes' ]
// ]
//},
blockReplacements: {
cssQuoted: function(block){
return '\'<link rel="stylesheet" href="' + block.dest + '">\'';
},
concatjs: function (block) {
return '<script src="' + block.dest + '"></script>';
}
}
}
},
script.js 片段:
var theme = getUrlParameter('theme');
var cssHrefString;
// we need fully qualified css tags below otherwise grunt build will not be able to pick them up
if (theme === 'testtheme' || theme === 'testtheme/') {
cssHrefString =
<!-- build:cssQuoted({.tmp,app}) styles/main_testtheme.css -->
'<link rel="stylesheet" href="styles/css/main_testtheme.css">'
<!-- endbuild -->
;
} else {
cssHrefString =
<!-- build:cssQuoted({.tmp,app}) styles/main.css -->
'<link rel="stylesheet" href="styles/css/main.css">'
<!-- endbuild -->
;
}
$('head').append(cssHrefString);
grunt 配置文件添加了concatjs的定义- 一个仅连接缩小文件的任务,不会在它们上运行 uglifier。cssQuoted获取块之间的字符串并将其替换为带引号的“link rel = ...”标签。
确保你的 grunt-usemin 插件版本是最新的——我花了几个小时尝试旧版本(~0.1.3)的选项。上面的代码适用于 3.0.0。
