熟练使用微信开发工具的代码块功能提升编码效率，降低误码率
1. 写在前面
自从上次介绍了宇宙第一强集成IDE的微信开发者工具安装插件等隐藏功能后，很多开发者社区哥们老铁感兴趣，一些哥们还私我问我是否支持代码块功能。答案是：支持！而且很完美的支持（此处必须有感恩，感恩微信团队每天的辛苦开发，作为同开发过小编辑器的人知道其中的苦与乐，同时呼吁各位猿少些喷喷喷的负能量，多些宣传和赞美的正能量！）。代码块是小编非常非常常用的一个功能，基本从04年开始建站和开发过程用过的所有IDE中都必备的功能。熟练使用微信开发工具的代码块功能提升编码效率，降低高频代码段的误写率。
2. 什么是代码块
可能有些刚接触开发的哥们不了解什么是「代码块」，这里我仅仅说说我个人对「代码块」功能的理解：代码块，英文名字：Code snippets,代码块的作用就是把比较长的一段代码在编码时只需要输入简写后的几个字母，比如把高频的代码console.log();简写成「clg」，再比如把小程序的页面.js里面的onLoad(),onShow等常用代码简写成「page_init」几个字母，最早提出这个概念和想法的人我也不知道是谁，总之得感谢他。如果说现在很多的编程语言有「语法糖」的说法，那么我个人觉得「代码块」可以称为「代码糖/编码糖」！熟练使用编码糖一定能让你尝到编码中的甜味。他的优点非常明显：极速，0误差输入高频代码段。个人觉得无论你现在处在编码的哪个级别都应该熟练使用Code snippets来提升工作效率。
3. 如何使用
3.1 打开开发者工具的编辑器扩展目录
[图片]
3.2 创建相关文件夹
返回上一级目录到User目下（里面有Workspaces文件夹），创建/进入snippets，此目录mac下完整路径应为："~/Library/Application Support/微信开发者工具/【当前开发者工具特征码】/Default/Editor/User/snippets"
[图片]
3.3 新建/编辑代码块json文件（如上图）
[图片]
格式如上面，1，2，3是我比较常用的代码糖，生效后输入图1里面的clg回车就是console.log()(可以用这个来检测你代码糖功能是否生效);并且光标自动定位到()里，如下图：

3.4 附带自用all.code-snippets
下面附上我常用的粗陋的代码糖块文件all.code-snippets（可以直接复制使用，你可以自行自己添加删除。里面有自己写的java框架常用的代码块,php常用和html常用以及nginx比较常用的，个人习惯不一样建议全部干掉重来，只需按里面的格式来写就可以了，格式如下：
