badoc

2010-04-06T00:46:40+00:00

badoc is a documentation generator tool for Lua. Somewhat like LuaDoc () but it uses specific Lua scripts as input, instead of parsing the source code for special comments. Currently only the HTML generator is implemented.

cpso

2010-07-13T00:41:36+00:00

cpso is a library that implements a Particle Swarm Optimization algorithm for continuous variables. It's small (less than 200 lines of code) and tries to be simple. License This software is licensed under the GNU Lesser General Public License. Download Sources. There are Arch Linux packages in the AUR.

gnet

2009-02-20T03:17:56+00:00

lnet is a partial binding of gnet to Lua, to allow asynchronous network communication using a single lua state. License This software is licensed under the GNU Lesser General Public License. Dependencies Lua 5.1, gnet 2.0. Download Sources. There are Arch Linux packages in the AUR.

lcl

2010-04-06T00:42:44+00:00

lcl is a small l10n and l18n library for Lua, that uses the ISO C locale.h and gettext. License This software is licensed under the GNU Lesser General Public License. Download Sources. There's an Arch Linux package in the AUR. Source repository

ldbi

2009-02-02T14:53:08+00:00

ldbi binds popular database engines to Lua. Currently supports PostgreSQL and SQLite. Example: require("ldbi.postgres") require("config") local conn, cur, err, msg conn, err, msg = postgres.connect(config) cur, err, msg = conn:execute([["SELECT * FROM mytable"]]) local row = cur:fetch({}) while row do print(row[1], row[2]) row = cur:fetch(row) end -- not needed, but it's good to release resources ASAP cur:close() conn:close()

ldraw

2008-11-13T01:54:30+00:00

ldraw is a Cairo binding for Lua, that tries to be simple and efficient. Can be used alone, with file backends, or with lgui, to draw on windows. Example: require("ldraw") local surface = ldraw.Surface.create(ldraw.FORMAT_ARGB32, 300, 300) local cr = ldraw.Context.create(surface) cr:rectangle(20, 20, width - 40, height - 40) cr:setSourceRgb(0, 0, 1) cr:fill() surface:writeToPng("Output.png") cr:destroy() surface:destroy()

lfann

2009-07-27T20:49:07+00:00

lfann is a FANN binding for Lua, that maintains FANN easy-to-use interface and excellent performance. Example: require("lfann") local net = fann.Net.create_from_file("xor.net") local output = net:run{1, 0} print(output[1]) License This software is licensed under the GNU Lesser General Public License.

lglext

2009-02-02T14:53:08+00:00

lglext is a GtkGLExt binding for Lua, that works with lgui and any OpenGL binding. It makes possible to embed OpenGL in a GTK+ Widget. License This software is licensed under the GNU Lesser General Public License. Dependencies Lua 5.1, lgui 0.20 and GtkGLExt 1.2 (plus an OpenGL binding at runtime).

lgob

2010-07-12T01:58:05+00:00

Lua bindings to GObject-based libraries like GTK+, WebKitGtk, and GStreamer (and others like Cairo). lgob is portable, have a small overhead, works with different versions of libraries and features a code generator that can be used in other projects / bindings.

lgui

2009-07-02T21:03:06+00:00

lgui is a GTK binding for Lua, making the process of wp>GUI creation more productive. Its suitable for a range of applications, such as prototyping and small scripts, up to big enterprise applications. lgui is portable, and have a good memory consumption (very small overhead, Lua itself is very spartan).

lmedia

2008-09-18T15:13:43+00:00

lmedia is a GStreamer binding for Lua. Takes advantage of the dynamic, plugin-based to be as small as possible. Example: require("lmedia") local pipe = lmedia.ElementFactory.make("playbin", "player") local main = lobj.MainLoop.new() pipe:set("uri", arg[1]) pipe:setState(lmedia.STATE_PLAYING) main:run()

lnet

2009-02-20T03:23:11+00:00

lneural

2010-11-29T00:41:54+00:00

lneural is a pure Lua implementation of an artificial neural network that implements a modified backpropagation algorithm for the training. Although it isn't as fast as C libraries, it's performance is sufficient for many problems, when used with LuaJIT. See lfann for Lua bindings to the FANN library, and SuperNN for a library that implements more advanced supervised training algorithms.

lobj

2008-09-09T19:23:28+00:00

lobj is a GLib and GObject binding for Lua. Can be used alone for its utilities or as basis of GObject-based bindings to Lua. It's currently used by lgui and lmedia. Currently is tested only with Arch Linux x86/x64, Debian Lenny x64, Fedora 9 x86 and Win32, but should work on other systems.

luaplot

2010-08-03T01:43:04+00:00

luaplot is a plotting library for Lua, based on CairoPlot. It uses cairo as drawing library (supporting several output formats) and can be integrated with GTK+. License This software is licensed under the GNU Lesser General Public License. Dependencies lgob with the cairo module (gtk module is optional).

neuralview

2010-08-31T00:23:53+00:00

NeuralView is a neural network simulator, with a multi-platform graphical interface. License This software is licensed under the GNU General Public License. Dependencies Lua 5.1, lgob 11.10+ (modules: gobject, gtk (>= 3) , cairo), lcl 1.0+, lfann 1.0+, gnuplot (optional)

supernn

2011-01-06T23:22:13+00:00

SuperNN is an artificial neural network library, with support to arbitrary feed-forward topologies, that implements state-of-the-art supervised training algorithms such as Improved Resilient Backpropagation (iRprop) [Igel and Hüsken, 2000] and Neuron by Neuron (NBN) [Wilamowski, Yu, 2010].
