This is a Common Lisp library providing various utilities.

This package contains a few utility functions from the LispWorks library that are used in software such as ContextL.

This library simplifies functional programming in Common Lisp by making it easier to make new data structures with specified changes in place.

PARSE is a simple token parsing library for Common Lisp.

The Plump-SEXP library is a backend for Plump which can convert between S-expressions and the Plump DOM.

This library contains an implementation of interfaces and implementations. They're sometimes called protocols in other languages. Broadly speaking, an interface is some collection of function prototypes that a valid implementation must implement.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and Open Location Code.

This package contains the specification of all functions and variables from GLSL as data.

trivial-clipboard gives access to the system clipboard.

This is a Commin Lisp library for operating on permutations and permutation groups.

This is a collection of useful helper modules and standard implementations for Radiance interfaces.

TRIVIAL-OCTET-STREAMS is a Common Lisp library implementing in-memory octet streams analogous to string streams.

This is a simple queue library for Common Lisp with features such as non-consing thread safe queues and fibonacci priority queues.

Parse-Declarations is a Common Lisp library to help writing macros which establish bindings. To be semantically correct, such macros must take user declarations into account, as these may affect the bindings they establish. Yet the ANSI standard of Common Lisp does not provide any operators to work with declarations in a convenient, high-level way. This library provides such operators.

Lack is a Common Lisp library which allows web applications to be constructed of modular components. It was originally a part of Clack, however it's going to be rewritten as an individual project since Clack v2 with performance and simplicity in mind.

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.

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

CHRONICITY is Common Lisp natural language date and time parser inspired by Ruby's Chronic.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and UTM (Universal Transverse Mercator) or UPS (Universal Polar Stereographic).

ZPB-TTF is a TrueType font file parser that provides an interface for reading typographic metrics, glyph outlines, and other information from the file.

This library allows for cooperative multitasking with help of cl-cont for continuations. It tries to mimic the API of bordeaux-threads as much as possible.

This package provides a library for parsing MIME types, in the spirit of http://code.google.com/p/mimeparse/, with a Common Lisp flavor.

This prompter library is heavily inspired by Emacs' minibuffer and Helm (https://emacs-helm.github.io/helm/). It only deals with the backend side of things, it does not handle any display. Features include asynchronous suggestion computation, multiple sources, actions and resumable prompters.

Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.
