SublimeText3系列（3）- HTML-CSS-JS Prettify美化代码&Ma

摘要：今天主要介绍与两个插件插件使用来格式化与代码。可以在这里尝试的效果原始代码格式化后的代码有了这个，个人认为在前端开发中，可以不用和这两个插件。的代码对齐也有，实际上也用的是。其目标是成为一种适合书写的网络语言。

今天主要介绍HTML-CSSS-JS Prettify与Markdown Preview两个插件

HTML-CSSS-JS Prettify插件使用js-beautify来格式化js、html与css代码。
可以在这里尝试js-beautify的效果
原始代码：

// This is just a sample script. Paste your real code (javascript or HTML) here.

if ("this_is"==/an_example/){of_beautifier();}else{var a=b?(c%d):e[f];}

格式化后的代码：

// This is just a sample script. Paste your real code (javascript or HTML) here.
if ("this_is" == /an_example/) {
    of_beautifier();
} else {
    var a = b ? (c % d) : e[f];
}

有了这个，个人认为在前端开发中，可以不用Alignment和JsFormat这两个插件。
Alignment的代码对齐HTML-CSS-JS Prettify也有，JsFormat实际上也用的是js-beautify。
如果只是针对html、css与js代码，HTML-CSS-JS Prettify就够了

HTML-CSSS-JS Prettify插件使用的是node版的js-beautify，因此需要首先安装node，node的安装请自行搜索。
在node安装完成后，使用npm安装js-beautify，命令 npm install -g js-beautify
HTML-CSS-JS Prettify的安装推荐使用PackageControl
Ctrl+Shift+P输入Install Package，然后输入HTML-CSS-JS Prettify进行安装

HTML-CSS-JS Prettify配置可使用.jsbeautifyrc文件，js-beautify会在被优化代码文件的当前目录查找，如果找不到会向上级目录查找。
因此，可以在项目的根目录新建.jsbeautifyrc文件来配置js-beautify
贴一下我的配置，是从这里扣下来的,改的比较少

  }
}

主要的改动就是

修改了"html"的"allowed_file_extensions"，增加了aspx和jsp的支持

修改了"css"的"selector_separator_newline"，个人觉得没必要每个选择器都要占一行

修改了"js"的"allowed_file_extensions"，增加了.csslintrc文件的支持

修改了"html"、"css"、"js"的"indent_size"，我的代码缩进为2个空格

使用Ctrl+Shift+H，优化当前代码文件。
使用js文件测试一下，优化前

优化后

js-beautify对css的格式化，有个问题是，会在注释下面插入一行空白字符
如下图，优化前

优化后

sublime text 3 插件：HTML-CSS-JS Prettify文中给出了解决方法，大家可以参考

Markdown的语法全由一些经过精挑细选的符号所组成。其目标是成为一种适合 书写的网络语言。
Markdown 是一种方便记忆、书写的纯文本标记语言，用户可以使用这些标记符号以最小的输入代价生成极富表现力的文档。
比如这篇博客就是用Markdown语法写的。
关于Markdown语法，可参考中文文档

Markdown Preview的安装推荐使用PackageControl
Ctrl+Shift+P输入Install Package，然后输入Markdown Preview进行安装

可使用SublimeText3创建.md文件，按照Markdown语法输入要写的内容，如下图

然后Ctrl+Shift+P输入mp，选择Markdown Preview: Preview in Browser,选择markdown，在浏览器中打开

在浏览器中的Markdown文档效果如下

在修改Markdown文档后，可以刷新浏览器页面，查看更新效果
