cl-xkb is a Common Lisp wrapper for the libxkbcommon keyboard handling library.

The library currently supports these xkb modules:

• Keysyms

• Library Context

• Include Paths

• Logging Handling

• Keymap Creation

• Keymap Components

• Keyboard State

• Compose and dead-keys support

A utility for running external programs, built on UIOP. Cmd is designed to be natural to use, protect against shell interpolation and be usable from multi-threaded programs.

This package provides a standard interface to the various package lock implementations of Common Lisp.

This library implements efficient algorithms that calculate various string metrics in Common Lisp:

• Damerau-Levenshtein distance

• Hamming distance

• Jaccard similarity coefficient

• Jaro distance

• Jaro-Winkler distance

• Levenshtein distance

• Normalized Damerau-Levenshtein distance

• Normalized Levenshtein distance

• Overlap coefficient

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

This package is a simple date and time library.

This is a small OS portability library to retrieve and set file attributes not supported by the Common Lisp standard functions.

Screamer is an extension of Common Lisp that adds support for nondeterministic programming. Screamer consists of two levels. The basic nondeterministic level adds support for backtracking and undoable side effects. On top of this nondeterministic substrate, Screamer provides a comprehensive constraint programming language in which one can formulate and solve mixed systems of numeric and symbolic constraints. Together, these two levels augment Common Lisp with practically all of the functionality of both Prolog and constraint logic programming languages such as CHiP and CLP(R). Furthermore, Screamer is fully integrated with Common Lisp. Screamer programs can coexist and interoperate with other extensions to as CLIM and Iterate.

This is a Common lisp library to unify access to the most common dictionary-like data structures.

Conium is a portability library for debugger- and compiler-related tasks in Common Lisp. It is fork of SWANK-BACKEND.

CL-FTP is a library which provides FTP client functionality to a Common Lisp program. CL-FTP uses the USOCKET package for network sockets and the SPLIT-SEQUENCE package for some parsing needs.

This library is a path strings manipulation library inspired by Python's os.path. All functionality from os.path is supported on major operation systems.

The philosophy behind is to use simple strings and "dumb" string manipulation functions to handle paths and filenames. Where possible the corresponding OS system functions are called.

Smart-buffer provides an output buffer which changes the destination depending on content size.

This piece of code sets up some reader macros that make it simpler to input string literals which contain backslashes and double quotes This is very useful for writing complicated docstrings and, as it turns out, writing code that contains string literals that contain code themselves.

This package provides Common Lisp bindings to POSIX message queue, an IPC method that is easy to use and quick to setup.

This is a Common Lisp library to load images in the PNG image format, both from files on disk, or streams in memory.

ORG-SAMPLER allows using Lisp docstrings and reflection to make org-mode text for inclusion into a larger document.

This library is a path strings manipulation library inspired by Python's os.path. All functionality from os.path is supported on major operation systems.

The philosophy behind is to use simple strings and "dumb" string manipulation functions to handle paths and filenames. Where possible the corresponding OS system functions are called.

EXTERNAL-PROGRAM enables running programs outside the Lisp process. It is an attempt to make the RUN-PROGRAM functionality in implementations like SBCL and CCL as portable as possible without sacrificing much in the way of power.

This package is a Python Numpy clone implemented in pure Common Lisp.

This is a trivial utility for distinguishing between a process running in a real terminal window and a process running in a dumb one, e.g. emacs-slime.

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.

Retrospectiff is a common lisp library for reading and writing images in the TIFF (Tagged Image File Format) format.

defclass-star provides defclass* and defcondition* to simplify class and condition declarations. Features include:

• Automatically export all or select slots at compile time.

• Define the :initarg and :accessor automatically.

• Specify a name transformer for both the :initarg and :accessor, etc.

• Specify the :initform as second slot value.

See https://common-lisp.net/project/defclass-star/configuration.lisp.html for an example.
