regex support #320

Open dcsan opened 5 years ago

dcsan commented 5 years ago

there doesn't seem to be an open issue for regex at the moment I recall there was a working doc somewhere to discuss this but hope you don't mind if i make an issue here.

this is a missing feature for rivescript that means it can't be used effectively for non-latin languages chinese/japanese etc. the simplied regex syntax depends on spaces which doesn't work

and also the ? syntax which is to find a single word in a phrase

BotML has first class support for regex and also some interesting ways to inline javascript for conditional testing https://github.com/codename-co/botml#regular-expression
