用vim正则环视优化vim-coloresque插件

vim-coloresque是一款高亮插件,将css/sass/less中的颜色用背景色高亮出来方便预览。用了一段时间发现代码补全一定程度上受影响,自己对插件进行了一些优化,修改后git地址:https://github.com/thinkjs/vim-coloresque

看插件github上的issue,插件中对isk这个选项的设置影响了补全,全并且影响了vim全局的keyword识别,直接注释掉isk+=-、isk+=#、 isk+=# 解决了补全问题但针对colorDict的高亮识别又发生错误,例如样式名为 .red或.common-red-btn,此处的red会被高亮。作者使用"\<"单词边界来识别colorDict,修改isk以后单词边界识别出错高亮出错,想到用正则表达式来调整此处的colorDict匹配。

匹配规则如下:
1. 前字符为行首或空白或:(冒号)
2. 后字符为行尾或空白或;(分号)

正则如下:
'\(^\|\s\|:\)\@<=\c'._color.'\($\|\s\|;\)\@='

vim中使用@<=作逆序环视、@=做顺序环视(vim中使用:h @<=查看详细介绍),修改后效果不错,符合我的应用场景。diff代码如下:
