RE

An simple implementation of Regex Expressions

Supports

• ASCII-text
• epsilon-closure
• or operator
• interactive interface

Passes

regex -> post-order form -> regex AST -> NFA -> DFA -> minimized_DFA

Special

On succeed, origin_DFA.gv minimized_DFA.gv and NFA.gv will be generated, which can be visualized using graphviz.

TODO

• • Richer syntactic features
• • File support
• • Interactive interface
• • Minimization algorithm
• • Turn to C++ to avoid making wheels
