Delphi/Pascal parser implementation

I'm trying to implement a program that is able to parse a subset of Delphi language and build a tree, that will be later be used in my software. The tree produced by the parser should be as compact as possible. This parser should be written in Pascal/Delphi (version 7 sintax) My original idea was to use Yacc for Delphi, I already got an almost complete parser yacc/lex that I wrote, that could be completed by you, but I am also open to other alternatives (as long as it is written in Pascal) Sintax features that should be supported: -Variables and constants, including arrays -Function and procedures -Type declarations, including records and objects -Classes, including inheritance -Properties Sintax features that should not be implemented: -Pointers -Interfaces -Variants Notes - For this job it would be ideal if you have experience with compilers. -About suggestions: - I know about RemObjects Pascal Script (as far as I know this one does not support class declarations inside the script code). Also I'm not interested in using the language as a script, but rather to integrate it with a mini compiler that will write once this job is completed.
