Abstract syntax tree builder for Delphi

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">
