NimBorg is a library for accessing Lua and Python libraries from within Nimrod code. It wraps the C API of these languages with macros which make the code far more readable than the low-level API, and also automatically handles the memory management interface of these languages so that objects aren't deallocated as long as they're accessible from your Nimrod code.
Cardpeek is a tool to read the contents of ISO7816 smartcards. It features a GUI to represent card data in a tree view, and it is extendable with a scripting language (LUA). The goal of this project is to allow smartcard owners to be better informed about what type of personal information is stored in these devices. The tool currently reads the contents of: EMV bank cards, Calypso public transport cards (such as Navigo, RavKav, and Mobib), Belgian eID cards, GSM SIM cards, the French Vitale 2 health card, some Mifare cards, and Moneo electronic purse cards.
iCan is an intelligent, community-driven command line that helps you to automate any kind of task arising in your daily Linux use. It is extensible through simple Lua modules, which run in a sandbox environment. It is designed to learn what you do and make things easier for you, every time you do something.
TuxBot is an IRC bot written in Lua. It was created to fit the requirements of the #linux channels on irc.oftc.net and irc.esper.net, but it is also used as a helpful bot in some other, non-Linux channels on other networks. The bot is able to link Linux channels on different networks by relaying messages between them. It is also able to kick flooders and to show the title of HTML pages after someone posted a link in a channel. Furthermore, TuxBot works as a raw multi-network IRC client for the console. There are some other features, such as the ability to extend TuxBot’s functionality using a simple module system.
cqueues is a comprehensive event and networking library for Lua 5.2 and LuaJIT using modern Unix O(1) polling facilities. It includes libraries for buffered socket I/O, SSL/TLS sockets, DNS querying, signal handling, threading, file change notification, and X.509 key management. It natively supports Linux, *BSD, OS X, and Solaris systems without third-party dependencies, and is interoperable with any event loop that accepts plain descriptors, or is usable standalone.
EGSL is a small interpreter which can execute Lua scripts. It includes some functions for fast and easy game development. These are image manipulation functions, functions for 2D drawing, sound and music, input via mouse, keyboard, and joypad, and some helper functions. The engine is based on SDL, SDL_gfx, and SDL_mixer, and additionally on SDL_image on Haiku-OS.
