This library provides low-level libuv bindings for Common Lisp.

Portability library for IEEE float features that are not covered by the Common Lisp standard.

This package provides Common Lisp bindings for libev.

repl-utilities is a set of utilities which ease life at the REPL. It includes three sorts of features: introspective procedures, miscellaneous utility functions, and, pulling them together, methods to conveniently keep these symbols and optionally additional symbols available in whichever package you switch to.

ST-JSON (ST because it originated at Streamtech) is a Common Lisp library for encoding and decoding JSON values (as specified on json.org).

This library does mostly the same thing as CL-JSON, but is simpler and more precise about types (distinguishing boolean false, the empty array, and the empty object).

This package provides a set of bindings and utilities for accessing the OpenGL (Mesa), GLU and GLUT (FreeGLUT) APIs using CFFI.

Pileup is a portable, performant, and thread-safe binary heap for Common Lisp.

This software provides an interface by which Common Lisp programs can access lexicographic data from WordNet.

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.

A mixture of features from eRuby and HTML::Template. You could name it "Yet Another LSP" (LispServer Pages) but it's a bit more than that and not limited to a certain server or text format.

The GNU Scientific Library for Lisp (GSLL) allows the use of the GNU Scientific Library (GSL) from Common Lisp. This library provides a full range of common mathematical operations useful to scientific and engineering applications. The design of the GSLL interface is such that access to most of the GSL library is possible in a Lisp-natural way; the intent is that the user not be hampered by the restrictions of the C language in which GSL has been written. GSLL thus provides interactive use of GSL for getting quick answers, even for someone not intending to program in Lisp.

Staple is a documentation system. It provides you with a way to generate standalone documentation accumulated from various sources such as readmes, documentation files, and docstrings.

Loop has a consistent interface unlike other looping abstractions and ANSI list operations. You can define your own efters and gatherers that integrate tightly into other operations. All operations are non-consing when possible.

Porter Stemming Algorithm.

This is a terminfo database front end in Common Lisp. The package provides a method for determining which capabilities a terminal (e.g. "xterm") has and methods to compile or put commands to a stream.

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.

This library lets you build a metaclass which in turn lets you specify extra slot options in its classes. Options may be easily inspected and custom inheritance may be set up. The Meta-Object Protocol (MOP) is used for the implementation - through closer-mop. Some convenience function for processing slot options are also available.

Possible use case: you want to automatically set up some definitions based on some slots, but you want to have control over it right in the class definition.

For is a library for an extensible iteration macro. It allows you to write concise looping constructs similar to loop and iterate. Unlike loop however it is extensible and sensible, and unlike iterate it does not require code-walking and is easier to extend.

This package provides Common Lisp FFI bindings for libwayland, primarily for the mahogany window manager.

This Common Lisp package provides a regular expression engine.

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.

This package provides a Common Lisp wrapper system for the SDL 2.0 Mixer C Library.

trivial-clipboard gives access to the system clipboard.

Max’s Parser Combinators is a simple and pragmatic library for writing parsers and lexers based on combinatory parsing. MaxPC is capable of parsing deterministic, context-free languages, provides powerful tools for parse tree transformation and error handling, and can operate on sequences and streams. It supports unlimited backtracking, but does not implement Packrat Parsing. Instead, MaxPC achieves good performance through its optimized primitives, and explicit separation of matching and capturing input. In practice, MaxPC parsers perform better on typical computer languages—when compared to Packrat parsers—at the expense of not producing linear-time parsers.
