Redo

I finally decided to go forward with a C# redo since the C++ version is too long and hard of a row to plow.

I've also cooked up a new syntax that is basically a prefix version of Python's syntax.

class Test():
    def Foo1($x is foo): #forward chaining method
        rule:
            $x has $y
            $y is bar
            -->
            $y is foo

I've already written a simple tokenizer based on this article about regular expression parsing in C#. Another article that was helpful was Python: Myths about Indentation. That only took one day. The rest of the week was spent agonizing whether to have the parser just read the token list or convert to s-expressions and then parse.

I finally went back to an earlier idea of writing a class called TokenTree that extends List(object) where each element is either a token or a subtree. This should make things easier on the parsing end for various reasons. The s-expression idea was kind of neat but it seems redundant since I need AST classes anyways.

Later on I'll have to dump the RegEx stuff and write a more sophisticated tokenizer but at least this was a quick way to get started. For now I need to start writing the recursive descent parsing functions and the AST classes.
