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;

interface

uses
  Unit2;

function Sum(A, B: Integer): Integer;

implementation

function Sum(A, B: Integer): Integer;
begin
  Result := A + B;
end;

end.

Sample outcome

<UNIT line="1" col="1" name="Unit1">
  <INTERFACE begin_line="3" begin_col="1" end_line="10" end_col="1">
    <USES begin_line="5" begin_col="1" end_line="8" end_col="1">
      <UNIT line="6" col="3" name="Unit2"/>
    </USES>
    <METHOD begin_line="8" begin_col="1" end_line="10" end_col="1" kind="function" name="Sum">
      <PARAMETERS line="8" col="13">
