Abstract Syntax Tree Builder for Delphi

With DelphiAST you can take real Delphi code and get an abstract syntax tree. One unit at time and without a symbol table though.

FreePascal and Lazarus compatible.

Sample input

unit Unit1;
interfaceuses
Unit2;
functionSum(A, B: Integer): Integer;
implementationfunctionSum(A, B: Integer): Integer;
begin
Result := A + B;
end;
end.

Sample outcome
