Envy is a configuration manager for various applications. Envy uses an environment variable to determine a configuration to use. This can separate configuration system from an implementation.

S-XML-RPC is an implementation of XML-RPC in Common Lisp for both client and server.

This is a library for representing and mapping colours between their various spaces.

STMX is a high-performance implementation of composable Transactional Memory, which is a concurrency control mechanism aimed at making concurrent programming easier to write and understand. Instead of traditional lock-based programming, one programs with atomic memory transactions, which can be composed together to make larger atomic memory transactions.

A memory transaction gets committed if it returns normally, while it gets rolled back if it signals an error (and the error is propagated to the caller).

Finally, memory transactions can safely run in parallel in different threads, are re-executed from the beginning in case of conflicts or if consistent reads cannot be guaranteed, and their effects are not visible from other threads until they commit.

Memory transactions give freedom from deadlocks, are immune to thread-safety bugs and race conditions, provide automatic roll-back on failure, and aim at resolving the tension between granularity and concurrency.

This Common Lisp library provides string encoding and decoding routines for IDNA, the International Domain Names in Applications.

Converts Markdown text into CommonDoc nodes and vice versa.

NASDF is an ASDF extension providing utilities to ease system setup, testing and installation.

• Simple way to fetch Git submodules and “do the right thing” for setup. This may effectively supersede Quicklisp. A benefit of using Git submodules over the default Quicklisp distribution is improved reproducibility.

• Test helpers, like distinction between offline and online tests, or continuous integration options, and warning reports.

• Installation helpers, for instance to install libraries, icons and desktop files to the right directories.

CL-PDF is a cross-platform Common Lisp library for generating PDF files.

CL-DISKSPACE is a Common Lisp library to list disks with the command line tool df and get disk space information using statvfs.

This library exports three symbols: with-raw-io, read-char, and read-line, to provide raw POSIX I/O in Common Lisp.

A heap-based priority queue whose first and foremost priority is speed.

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

cl-all is a library and script for evaluating Common Lisp expressions in multiple implementations.

This library retrieves locale information configured on the system. This is helpful if you want to write applications and libraries that display messages in the user's native language.

Fully auto-generated Common Lisp bindings to Raylib and Raygui.

QURI (pronounced "Q-ree") is yet another URI library for Common Lisp. It is intended to be a replacement of PURI.

An implementation of the exponential backoff algorithm in Common Lisp. Inspired by the implementation found in Chromium. Read the header file to learn about each of the parameters.

This is a reverse proxy server written in and configurable in Common Lisp. It supports WebSocket, HTTP, HTTPS, HTTP to HTTPS redirecting, port and host forwarding configuration using a real programming language, HTTP header and body manipulation (also using a real programming language).

Cells is a mature, stable extension to CLOS allowing one to create classes whose instances can have slot values determined by instance-specific formulas.

This is a portable Universal Resource Identifier library for Common Lisp programs. It parses URI according to the RFC 2396 specification.

This is a reverse proxy server written in and configurable in Common Lisp. It supports WebSocket, HTTP, HTTPS, HTTP to HTTPS redirecting, port and host forwarding configuration using a real programming language, HTTP header and body manipulation (also using a real programming language).

Alexandria is a collection of portable utilities. It does not contain conceptual extensions to Common Lisp. It is conservative in scope, and portable between implementations.

This package provides Common Lisp system collecting tools written to wrangle OpenGL Shader Language (GLSL) source files.

In Common Lisp, a special variable that is never dynamically bound typically serves as a stand-in for a global variable. The global-vars library provides true global variables that are implemented by some compilers. An attempt to rebind a global variable properly results in a compiler error. That is, a global variable cannot be dynamically bound.

Global variables therefore allow us to communicate an intended usage that differs from special variables. Global variables are also more efficient than special variables, especially in the presence of threads.
