Plog is a C++ logging library that is designed to be simple, small and flexible. It is created as an alternative to existing large libraries and provides some unique features such as CSV log format and wide string support.

Rsyslog offers high-performance, great security features and a modular design. While it started as a regular syslogd, rsyslog has evolved into a kind of swiss army knife of logging, being able to accept inputs from a wide variety of sources, transform them, and output the results to diverse destinations.

Spdlog is a very fast header-only/compiled C++ logging library.

Google glog is a library that implements application-level logging. This library provides logging APIs based on C++-style streams and various helper macros. You can log a message by simply streaming things to log at a particular severity level. It allows logging to be controlled from the command line.

This package provides a bare-bones logging library for C++, with only a printf-like syntax and five logging levels.

The log4cxx packages provides a C++ logging framework patterned after Apache log4j which uses the Apache Portable Runtime for most platform-specific code.

QLogo is an interpreter for the Logo language written in C++ using Qt and OpenGL. Specifically, it mimics, as reasonably as possible, the UCBLogo interpreter.

The Lout document formatting system reads a high-level description of a document similar in style to LaTeX and produces a PostScript or plain text output file.

Lout offers an unprecedented range of advanced features, including optimal paragraph and page breaking, automatic hyphenation, PostScript EPS file inclusion and generation, equation formatting, tables, diagrams, rotation and scaling, sorted indexes, bibliographic databases, running headers and odd-even pages, automatic cross referencing, multilingual documents including hyphenation (most European languages are supported), formatting of computer programs, and much more, all ready to use. Furthermore, Lout is easily extended with definitions which are very much easier to write than troff of TeX macros because Lout is a high-level, purely functional language, the outcome of an eight-year research project that went back to the beginning.

Lsof stands for LiSt Open Files, and it does just that. It lists information about files that are open by the processes running on the system.

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.

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

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.

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.

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 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.

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.

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.

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.

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.

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.
