Fare - [F]inite [A]utomata and [R]egular [E]xpressions

Project Fare is an effort to bring a DFA/NFA (finite-state automata) implementation from Java to .NET. There are quite a few implementations available in other languages today. This project aims to fill the gap in .NET.

Fare is a .NET port of the well established Java library dk.brics.automaton with API as close as possible to the corresponding dk.brics.automaton classes.

Is my Regular Expression supported?

Probably yes.

Keep in mind though that Project Fare turns Regular Expressions into Automatons by applying the algorithms of dk.brics.automaton and xeger.

If your Regular Expression isn't supported, it would make sense to debug the C# code but also compare with the results from xeger.

As an alternative, you may use a different pattern or even use a different engine to reverse the Regular Expression into an Automaton. As an example, you can use the Rex engine.

Design changes

  • Included a .NET port of Xeger, for generating random text from regular expressions. Xeger does not support all valid Java regular expressions. The full set of what is defined here and is summarized at (http://code.google.com/p/xeger/wiki/XegerLimitations).
  • Implemented object equality.
  • Many getters and setters have been replaced by .NET properties.
  • Many foreach loops have been converted to LINQ-expressions.
  • Notes from porting Java code in .NET can be found here.

Based on version 1.11-8 of dk.brics.automaton released on September 7, 2011. ChangeLog
