** This project is not currently functional. Unfortunately it grew a little too big for me to handle in my spare time, but hopefully I can at some point pick it back up. **
The purspose of this project is to provide with a very simple to use parser generator with a natural C# syntax. For example, a very simple expression language::
Define(() => Root, () => Expr);
Define(() => Expr, () => Multiplication.FollowedBy("\\+".FollowedBy(Multiplication).Optional()));
Define(() => Multiplication, () => Factor.FollowedBy("\\*".FollowedBy(Multiplication).Optional()));
Define(() => Factor, () => Constant.Or("\\(".FollowedBy(Expr, "\\)")));
Define(() => Constant, () => Digit.OneOrMore()); //> emit list of digits (1 or more)
Define(() => Digit, () => "1|2|3|4|5|6|7|8|9|0".Terminal());
The resulting graph can be "flattened" and compiled easily using .NET Expression trees, for example.
NOTE: currently this is not finished. I do intend to finish this at some point, but it grew a little bigger than initially anticipated.
