JavaScript正則表達式解析器和可視化：Regulex

JavaScript正則表達式解析器和可視化。
Visualizer : http://jex.im/regulex/

特性:

• 采用純JavaScript編寫。不需要后端。
• 在你自己的網站通過HTML iframe元素嵌入圖形。
• 詳細的錯誤信息。在大多數情況下，它可以指出的精確語法錯誤的位置。
• 沒有對八進制轉義支持. Yes it is a feature. ECMAScript strict mode doesn't support octal escape in string,but many browsers still support octal escape in regex. I make things easier. In regulex, DecimalEscape will always be treated as back reference. If the back reference is invalid, e.g. /\1/、/(\1)/、/(a)\2/,or DecimalEscape appears in charset（because in this case it can't be explained as back reference, e.g. /(ab)[\1]/）. Regulex will always throw an error.
</ul>

API:

var parse = require('regulex/parse');
var re = /var\s+([a-zA-Z_]\w*);/ ;
console.log(parse(re));
