Regex und "ENTER"

[Chefx]

Also mein Projekt

Ich hab mir ans ziel gesetzt ein Syntax Highlighter für Websprachen zu entwickeln.
Hab jetzt zurzeit folgendes Konzept mir ausgedacht:

• Bestimmte muster mit Regex suchen (in verschiedene Arrays speichern)
• dann die verschiedenen Arrays fehlerfrei als rtf ausgeben
• die RTF wird durch RTF-Code erstellt und dann in Das Richedit geladen

das funktioniert super bloß das mit den neuen zeilen funktioniert noch nicht richtig!

Hier mal mein Projekt(Werde das wenn es fertig ist veröffentlich):

Delphi-Quellcode:

unit Unit3;

interface

uses
  Windows, Messages, SysUtils, Variants, Classes, Graphics, Controls, Forms,
  Dialogs, StdCtrls, ComCtrls;

type arrayf = array of array[0..1] of string;

type
  TForm3 = class(TForm)
    Button1: TButton;
    RichEdit1: TRichEdit;
    Edit1: TEdit;
    Memo1: TMemo;
    procedure RichEdit1Change(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  private
    { Private-Deklarationen }
  public
    { Public-Deklarationen }
  end;

var
  Form3: TForm3;

implementation

uses perlregex;

initialization

// nur wenn ein Debugger vorhanden, den Patch ausführen
if DebugHook<>0 then
   PatchINT3;
end.

Aber wo liegt mein Fehler?
