基于CodeMirror&TernJS的汉语Javascript编辑器（和翻译器）

http://www.ternjs.net/

TernJS.net提供了一个DEMO，正是支持语法高亮和智能感知的Javascript编辑器；于是我突发奇想，修改其中的Javascript parser，有了下面的汉语JS，名曰EJS。

主文件 doc/demo.html

代码检阅：https://github.com/xuhongxu96/EJS

主要特性：

1、关键词汉化

2、支持拼音输入的智能感知

改造过程：

请先从ternjs.net获取tern源代码。

一、文件 tern-master/lib/tern.js

1、修改关键词

 var jsKeywords = ("跳出 循环做 实例之于 类型之于 分支 否则 创建 变量 真 假 " +
        "捕获 善后 返回 无类型 继续 变量循环 判断 循环当 调试中断 " +
        "函数 我 语句组 默认 如果 抛出 删除 于 异常处理 空").split(" ");

2、增加拼音匹配引擎
