PCB 规则引擎之编辑器(语法着色,错误提示,代码格式化)

对于一个规则引擎中的脚本代码编辑器是非常关键的,因为UI控件直接使用对象是规则维护者,关系到用户体验,在选用脚本编辑器的功能时除了满足代码的编辑的基本编辑要求外，功能还需要包含;语法着色,错误提示,代码格式化,代码折叠,自动代码提示,自动补全代码等功能.(目前技术无法做到JS加断点;边调试边运行)

经过众多开源产品的代码编辑器对比与功能测试，ICSharpCode.TextEditor 是JS脚本编辑器最佳选择. 

 

一.语法着色

    JS语法着色XML,对JS关键字进行着色,并可以扩展自指定义关键字着色，

    应用场影：规则引擎中新增加函数或变量等关键字时, 为用户体验更好，可增加自定义关键字着色;

              例：BoardThick 是关键字,那么在JS代码中，以高亮着色加以区分
