The NUMPY-FILE-FORMAT library is a Common Lisp library for reading and writing NumPy .npy and .npz files.

Markup allows the use of HTML syntax with in Common Lisp code. This has the advantage of being able to copy HTML snippets and have them instantly be functional, less double quotes than a s-expression approach, and designers will be able to understand the embedded HTML.

This library is an implementation of Deflate (RFC 1951) decompression, with optional support for ZLIB-style (RFC 1950) and gzip-style (RFC 1952) wrappers of deflate streams. It currently does not handle compression.

Generic documentation builder for Common Lisp projects.

This is a library for selecting portions of sequences, arrays or data-frames.

This library is an implementation of the XML Path Language (XPath) Version 1.0.

This is a Common Lisp library which provides functionality to read/write Bit Map Font (BMF) into text, JSON and XML.

This package provides the Common Lisp part of the emacs-slite test runner.

CL-octet-streams is a library implementing in-memory octet streams for Common Lisp. It was inspired by the trivial-octet-streams and cl-plumbing libraries.

RTG-MATH provides a selection of the math routines most commonly needed for making realtime graphics in Lisp.

This package provides an enhanced version of typep that is exactly like the one in the Lisp spec, except it can also accept a single type argument, in which case it returns the appropriate closure.

Common Lisp library for channel-based concurrency. In a nutshell, you create various threads sequentially executing tasks you need done, and use channel objects to communicate and synchronize the state of these threads.

This package holds an enhanced implementation of hooks (extension points). It works similarly to Emacs hooks with crucial improvements:

• If the compiler allows it (such as SBCL), type-checking is performed at compile-time and at run-time when adding handlers to a hook.

• On failure, multiple restarts are offered, such as disabling the offending handler or simply continuing to the next function.

• The hook handler execution order and combination can be customized.

• Anonymous functions (lambdas) can be added to hooks as handler objects. When inspecting hooks, readable names are thus exposed instead of lambda blackboxes. Handlers are compared through their names (through the mandatory name slot). A hook can not contain multiple handlers with the same name.

• A special provision is taken for “setters”, handlers that are meant to set a given place to a given values. Such handler objects can be compared and identified uniquely.

This package provides CFFI bindings to the libflac audio library for Common Lisp.

Vernacular is a build and module system for languages that compile to Common Lisp. It allows languages to compile to Lisp while remaining part of the Common Lisp ecosystem. Vernacular languages interoperate with Common Lisp and one another.

Vernacular handles locating files, compiling files into FASLs, tracking dependencies and rebuilding, and export and import between your new language, Lisp, and any other language Vernacular supports.

Vernacular builds on Overlord and is inspired by Racket.

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

This is an implementation of the Unicode Standards Annex #14 (http://www.unicode.org/reports/tr14/) line breaking algorithm. It provides a fast and convenient way to determine line breaking opportunities in text.

Note that this algorithm does not support break opportunities that require morphological analysis. In order to handle such cases, please consult a system that provides this kind of capability, such as a hyphenation algorithm.

Also note that this system is completely unaware of layouting decisions. Any kind of layouting decisions, such as which breaks to pick, how to space between words, how to handle bidirectionality, and what to do in emergency situations when there are no breaks on an overfull line are left up to the user.

This is a library to find system font files. It works on systems with FontConfig on Linux, BSD. It does not have any foreign dependencies that aren't already directly available on the system.

ALEXA is a tool similar to lex or flex for generating lexical analyzers. Unlike tools like lex, however, ALEXA defines a domain-specific language within your Lisp program, so you don't need to invoke a separate tool.

HARMONY is a library that provides you with audio processing tools as well as an audio server to play back music, sfx, and so forth. It is most suited for use in a game engine, but may feasibly also be used for more advanced things such as a DAW

This is a Common Lisp library to calculate std140 or std430 layouts for a glsl UBO/SSBO.

This is a pure Common Lisp library to create, transform and render anti-aliased vectorial paths.

THE-COST-OF-NOTHING is a library for measuring the run time of Common Lisp code. It provides macros and functions for accurate benchmarking and lightweight monitoring. Furthermore, it provides predefined benchmarks to determine the cost of certain actions on a given platform and implementation.

A Common Lisp library for generating a human-readable diff of two HTML documents.
