From c803e0cca1ef1e81bec4dcd615aea955f3756b19 Mon Sep 17 00:00:00 2001 From: Teravus Ovares Date: Thu, 1 May 2008 16:39:02 +0000 Subject: * Deletes my EventReader ScriptRewriter. It isn't required to rewrite the script to publish the events anymore. * Introduces a language(regex) independent event recognizer and publishes the events the script listens. --- .../Compiler/LSL/EventReaderRewriter.cs | 488 --------------------- 1 file changed, 488 deletions(-) delete mode 100644 OpenSim/Region/ScriptEngine/DotNetEngine/Compiler/LSL/EventReaderRewriter.cs (limited to 'OpenSim/Region/ScriptEngine/DotNetEngine/Compiler/LSL/EventReaderRewriter.cs') diff --git a/OpenSim/Region/ScriptEngine/DotNetEngine/Compiler/LSL/EventReaderRewriter.cs b/OpenSim/Region/ScriptEngine/DotNetEngine/Compiler/LSL/EventReaderRewriter.cs deleted file mode 100644 index 46ba850..0000000 --- a/OpenSim/Region/ScriptEngine/DotNetEngine/Compiler/LSL/EventReaderRewriter.cs +++ /dev/null @@ -1,488 +0,0 @@ -/* -* Copyright (c) Contributors, http://opensimulator.org/ -* See CONTRIBUTORS.TXT for a full list of copyright holders. -* -* Redistribution and use in source and binary forms, with or without -* modification, are permitted provided that the following conditions are met: -* * Redistributions of source code must retain the above copyright -* notice, this list of conditions and the following disclaimer. -* * Redistributions in binary form must reproduce the above copyright -* notice, this list of conditions and the following disclaimer in the -* documentation and/or other materials provided with the distribution. -* * Neither the name of the OpenSim Project nor the -* names of its contributors may be used to endorse or promote products -* derived from this software without specific prior written permission. -* -* THIS SOFTWARE IS PROVIDED BY THE DEVELOPERS AS IS AND ANY -* EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED -* WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE -* DISCLAIMED.
