+# DelphiLua
+*definitely not the most creative project name*
+
+This project consists of two parts: a straight-up conversion of the [LuaBinaries](http://luabinaries.sourceforge.net/) 5.2 C headers to Delphi, and the TLua class to make integrating Lua with Delphi projects easier.
+
+##### A note on compatibility
+It's been tested and developed on Delphi XE2 32-bits. Minimum version for the wrapper is probably 2010, due to anonymous functions and TRttiContext being used. I also know for sure that the code isn't 64-bits compatible yet.
+
+
+### Getting started
+If you're just interested in the API, the [Lua manual](http://www.lua.org/manual/5.2/manual.html#4) is the best place to start.
+
+For the wrapper, take a look at the unit tests in TestWrapper.pas. Be sure to copy Lua52.dll into the output path if you're gonna run the unit tests or your own project.
+
+
+##### A very, very simple example
+Load a script from a string, passing two variables A and B and having the script sum them up into variable C.
+
+```delphi
+var
+  lua: TLua;
+  returnValue: Integer;
+
+begin
+  lua := TLua.Create;
+  try
+    lua.SetGlobalVariable('A', 5);
+    lua.SetGlobalVariable('B', 10);
+
+    lua.LoadFromString('C = A + B');
+
+    returnValue := lua.GetGlobalVariable('C').AsInteger;
+  finally
+    FreeAndNil(lua);
+  end;
+end;
+```
+
+...of course, you can do much more exciting things like calling Delphi functions from Lua or vice versa. Check out the Call and RegisterFunction(s) methods. Have fun!
