Convenient macros for common lambda patterns.

Library to fuzzily parse time and date strings into a universal-time timestamp.

This is a minimalistic parser of command line options. The main advantage of the library is the ability to concisely define command line options once and then use this definition for parsing and extraction of command line arguments, as well as printing description of command line options (you get --help for free). This way you don't need to repeat yourself. Also, unix-opts doesn't depend on anything and precisely controls the behavior of the parser via Common Lisp restarts.

Just wrap your Common Lisp function in this macro call and it will be optimized for tail recursion. You will be warned if the function is not tail recursive.

This package provides a Common Lisp implementation of the semantic versioning specification: http://semver.org.

This package provides a Common Lisp system which wraps the BORDEAUX-THREADS system to be able to run things in the main thread of the implementation, for example drawing calls of GUI applications.

This is a backend for the linear-programming Common Lisp library using the GNU Linear Programming Kit (GLPK) library.

Common Music (CM) is a real-time music composition system.

cl-alexandria-plus is a conservative set of extensions to cl-alexandria utilities.

BST is a Common Lisp library for working with binary search trees that can contain any kind of values.

Very basic library for dealing with CL's hash tables. The idea was spawned through working with enough JSON APIs and config files, causing a lot of headaches in the process.

Simplified-Types is a library that provides functions for simplifying Common Lisp type specifiers. The API consists of two functions:

• simplify-type takes a type specifier and, optionally, an environment, and returns the corresponding simplified type.

• simplified-type-of takes an object and returns the simplified type of that object.

This package provides a Common Lisp Twitter client featuring full API coverage.

This is a lisp implementation of the Open Sound Control protocol (or more accurately “data transport specification” or “encoding”). The code should be close to ANSI standard common lisp and provides self contained code for encoding and decoding of OSC data, messages, and bundles.

Optima is a fast pattern matching library which uses optimizing techniques widely used in the functional programming world.

POLICY-COND provides tools to insert and execute code based on a compiler's OPTIMIZE policy. It also contains a contract-like notion of expectations, which allow dynamic checking or inclusion of various things that should happen depending on compiler policy.

cl-cron is a simple tool that provides cron like facilities directly inside of Common Lisp.

This package provides a way of extracting and replicating the compile-time side-effects of forms.

A library for encoding text in various web-savvy encodings.

The 3D-Spaces library implements a number of spatial query data structures; structures that can answer spatial range queries for optimized lookup, particularly suited for games.

CL-PPCRE is a portable regular expression library for Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

RE is a small, portable, lightweight, and quick, regular expression library for Common Lisp. It is a non-recursive, backtracing VM.

This is a Common Lisp library implementing the full v1 REST API protocol for Mastodon.

Cl-tga was written to facilitate loading .tga files into OpenGL programs. It's a very simple library, and, at the moment, only supports non-RLE encoded forms of the files.
