Lua is a powerful, fast, lightweight, embeddable scripting language. Lua combines simple procedural syntax with powerful data description constructs based on associative arrays and extensible semantics. Lua is dynamically typed, runs by interpreting bytecode for a register-based virtual machine, and has automatic memory management with incremental garbage collection, making it ideal for configuration, scripting, and rapid prototyping.

LuaSocket is a Lua extension library that is composed by two parts: a C core that provides support for the TCP and UDP transport layers, and a set of Lua modules that add support for functionality commonly needed by applications that deal with the Internet.

Among the supported modules, the most commonly used implement the SMTP (sending e-mails), HTTP (WWW access) and FTP (uploading and downloading files) client protocols. These provide a very natural and generic interface to the functionality defined by each protocol. In addition, you will find that the MIME (common encodings), URL (anything you could possible want to do with one) and LTN12 (filters, sinks, sources and pumps) modules can be very handy.

Lunit is a unit testing framework for Lua. It includes lunitx extensions adding Lua 5.2 compatibility via lunit.module and the lunitx module for running tests automatically at program exit.

Fennel Language Server is a language server for the Fennel programming language.

LuaSec is a binding for OpenSSL library to provide TLS/SSL communication. It takes an already established TCP connection and creates a secure session between the peers.

LuaFileSystem is a Lua library developed to complement the set of functions related to file systems offered by the standard Lua distribution. LuaFileSystem offers a portable way to access the underlying directory structure and file attributes.

Lutok is a lightweight C++ API library for Lua.

Lutok provides thin C++ wrappers around the Lua C API to ease the interaction between C++ and Lua. These wrappers make intensive use of RAII to prevent resource leakage, expose C++-friendly data types, report errors by means of exceptions and ensure that the Lua stack is always left untouched in the face of errors. The library also provides a small subset of miscellaneous utility functions built on top of the wrappers.

Lutok focuses on providing a clean and safe C++ interface; the drawback is that it is not suitable for performance-critical environments. In order to implement error-safe C++ wrappers on top of a Lua C binary library, Lutok adds several layers or abstraction and error checking that go against the original spirit of the Lua C API and thus degrade performance.

The luaossl extension module for Lua provides comprehensive, low-level bindings to the OpenSSL library, including support for certificate and key management, key generation, signature verification, and deep bindings to the distinguished name, alternative name, and X.509v3 extension interfaces. It also binds OpenSSL's bignum, message digest, HMAC, cipher, and CSPRNG interfaces.

This package provides a Lua parser for djot, a light markup syntax. It can produce an AST, rendered HTML, or a stream of match tokens that identify elements by source position, which could be used for syntax highlighting or a linting tool.

This Lua library provides LPeg lexers for source code syntax highlighting. It can either be used by itself or as a drop-in replacement for Scintilla lexers.

This Lua module offers an interface to the GNU readline library.

The function readline() is a wrapper, which invokes the GNU readline, adds the line to the end of the history list, and then returns the line. Usually you call save_history() before the program exits, so that the history list is saved to the histfile.

This Lua module can dialogue with the user on the controlling-terminal of the process (typically /dev/tty) as returned by ctermid(). It also support most of readline's alternative interface, namely handler_install, read_char and handler_remove, and readline's custom completion.

Lunit is a unit testing framework for Lua. It includes lunitx extensions adding Lua 5.2 compatibility via lunit.module and the lunitx module for running tests automatically at program exit.

The luaossl extension module for Lua provides comprehensive, low-level bindings to the OpenSSL library, including support for certificate and key management, key generation, signature verification, and deep bindings to the distinguished name, alternative name, and X.509v3 extension interfaces. It also binds OpenSSL's bignum, message digest, HMAC, cipher, and CSPRNG interfaces.

LuaSec is a binding for OpenSSL library to provide TLS/SSL communication. It takes an already established TCP connection and creates a secure session between the peers.

LuaExpat is a SAX XML parser based on the Expat library.

This Luanti mod adds many types of monsters to Luanti, that live on the surface or deep underground.

This Luanti mod adds new ore types to the game (mithril, silver) as well as swords and tools made of different materials. It also adds copper rails.

The purpose of this mod originally was to supply a complete set of colours for Luanti mod authors to use for colourised nodes or reference in recipes. Since the advent of the default dyes mod in the standard Luanti game, this mod has become an extension of the default mod an a library for general colour handling.

This mod adds arrows and bows to Luanti. It is a compatible replacement for the throwing mod by PilzAdam that uses the throwing API.

The homedecor Luanti mod provides a large seleection of items that might be found inside and around homes, such as sofas, chairs, tables, fences and a variety of other stuff.

This Luanti mod adds machinery and automation to Luanti. It adds various ores that can be processed for constructing various machinery, such as power generators, force field emitters, quarries and a workshop for repairing tools. Most machines are electrically powered.

This Luanti mod provides hundreds of colours of wood and fences to Luanti, using Unified Dyes. If the "moreblocks" mod is active, coloured and cut wood shapes are provided as well.

This package provides an extension of the Luanti game that lets you build your island in the sky. Every 30 seconds you will receive a random block or item from the oneblock to expand the island!

Pipeworks is a mod for Luanti implementing 3D pipes and tubes for transporting liquids and items and some related devices. Pipes and tubes can go horizontally or vertically. Item tubes can also be used for sorting items and extracting items from chests or putting items in chests. Autocrafters can automatically follow craft recipes to make new items and can be fed by item tubes. Deployers can place items in the world as a player would. Node breakers simulate a player punching a node.
