features
written in pure javascript. no backend needed. you can embed the graph in you own site through html iframe element. detailed error message. in most cases it can point out the precise syntax error position. no support for octal escape. 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.
