regex-ssm
=========
An attempt to demo [spring state machine](https://docs.spring.io/spring-statemachine/docs/current/reference/) with some
finite automata (regex evaluator).. and then I ended up writing more automata related code than state machine.
The parsing logic follows eliben's [work](https://github.com/eliben/code-for-blog/tree/master/2009/regex_fsm) since I wasn't
trying to redo my college project again.
