wxLua 220.127.116.11 Released
wxLua 18.104.22.168 is a long overdue stable bugfix release. There are a few new wxWidgets classes and functions. The binding generator has been changed to accept simple valid C++ code. The precompiled versions are linked against the SVN trunk of the wxWidgets 2.8 branch (2.8.12 with bug fixes). Note that the wxLua source code can be compiled against wxWidgets 2.9.x too.

What is wxLua ?
wxLua is a Lua scripting language wrapper around the wxWidgets cross-platform C++ GUI library. It consists of two IDE type editors that can edit, debug, and run Lua programs, an executable for running standalone wxLua scripts, a Lua module that may be loaded using require("wx") when using the standard Lua executable, and a library for extending C++ programs with a fast, small, fully embeddable scripting language.
Lua is a small scripting language written in ANSI C that can load and run interpreted scripts as either files or strings. The Lua language is fast, dynamic, and easy to learn. Lua contains a limited number of data types, mainly numbers, booleans, strings, functions, tables, and userdata. Perhaps the most powerful feature of the Lua language is that tables can be used as either numerically indexed arrays or associative arrays that can cross-reference any variable type to any other variable type.
wxLua adds to this small and elegant language nearly all of the functionality of the C++ wxWidgets cross-platform GUI library. This includes the ability to create complex user interface dialogs, file and image manipulation, drawing, network sockets, displaying HTML, and printing to name a few. You can use as much or as little of wxWidgets as you like and C++ developers can trim down the size of the bindings by turning off preprocessor directives.
wxLua can be built against wxWidgets 2.8.x, 2.9.x and Lua versions 5.1, 5.2, and LuaJIT.
The simple wxLua script below creates a wxFrame top-level window, with a menubar, and a statusbar. More examples of wxLua programs can be found in the samples directory of the wxLua distribution.
