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.

LPeg is a pattern-matching library for Lua, based on Parsing Expression Grammars (PEGs).

This package provides Lua module for nonblocking system shell command executions.

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.

This is the official OpenResty branch of LuaJIT. It is not to be considered a fork, since changes are regularly synchronized from the upstream LuaJIT project. This package also enables the Lua 5.2 compat mode needed by some projects.

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

This is a binding to libunbound for Lua, allowing both asynchronous and DNSSEC-secured DNS lookups of arbitrary DNS record types.

It was created because Prosody needs an asynchronous DNS library with support for SRV records, and the ones found at the time did one or the other, or was missing DNSSEC that allowed implementing DANE.

It originated out of a need in the XMPP server software Prosody for an async-capable resolver library supporting SRV records, as well as a desire to experiment with DNSSEC and new DNS records.

The cqueues extension module for Lua implements an event loop that operates through the yielding and resumption of coroutines. It is designed to be non-intrusive, composable, and embeddable within existing applications.

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.

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.

Fennel is a programming language that brings together the speed, simplicity, and reach of Lua with the flexibility of a Lisp syntax and macro system.

dkjson is a lua module for processing json in lua. It can handle tasks like encoding or decoding JSON objects to and from lua tables.

The cqueues extension module for Lua implements an event loop that operates through the yielding and resumption of coroutines. It is designed to be non-intrusive, composable, and embeddable within existing applications.

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.

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 library makes libuv available to Lua scripts.

LuaSQLite3 is a thin wrapper around the public domain SQLite3 database engine. It provides a complete binding to the SQLite3 C API from within Lua programs.

This package provides a way to turn Lua code into Fennel code. This compiler does the opposite of what the Fennel compiler does.

LPeg is a pattern-matching library for Lua, based on Parsing Expression Grammars (PEGs).

LDoc is a LuaDoc-compatible documentation generation system for Lua source code. It parses the declaration and documentation comments in a set of Lua source files and produces a set of XHTML pages describing the commented declarations and functions.

LGI is gobject-introspection based dynamic Lua binding to GObject based libraries. It allows using GObject-based libraries directly from Lua. Notable examples are GTK+, GStreamer and Webkit.
