• WAV

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.

This package provides an example implementation of the Common Lisp condition system and library, based on the original condition system implementation by Kent M. Pitman.

One of the many things that didn't quite get into the Common Lisp standard was how to get a Lisp to output its call stack when something has gone wrong. As such, each Lisp has developed its own notion of what to display, how to display it, and what sort of arguments can be used to customize it. trivial-backtrace is a simple solution to generating a backtrace portably.

The py-configparser package implements the ConfigParser Python module functionality in Common Lisp. In short, it implements reading and writing of .INI-file style configuration files with sections containing key/value pairs of configuration options. In line with the functionalities in the python module, does this package implement basic interpolation of option values in other options.

This is a small library to display a native GUI message box. This can be useful to show error messages and other informational pieces should the application fail and be unable to do so using its standard UI.

Sycamore is a fast, purely functional data structure library in Common Lisp. If features:

• Fast, purely functional weight-balanced binary trees.

• Leaf nodes are simple-vectors, greatly reducing tree height.

• Interfaces for tree Sets and Maps (dictionaries).

• Ropes.

• Purely functional pairing heaps.

• Purely functional amortized queue.

A Common Lisp library implementing a few different kinds of queues:

• Bounded and unbounded FIFO queues.

• Lossy bounded FIFO queues that drop elements when full.

• Unbounded random-order queues that use less memory than unbounded FIFO queues.

Additionally, a synchronization wrapper is provided to make any queue conforming to the jpl-queues API thread-safe for lightweight multithreading applications. (See Calispel for a more sophisticated CL multithreaded message-passing library with timeouts and alternation among several blockable channels.)

HTTP-Body parses HTTP POST data and returns POST parameters. It supports application/x-www-form-urlencoded, application/json, and multipart/form-data.

This package defines a Common Lisp package, :elements, with an ELEMENT structure and a number of functions to search the periodic table.

This is a a Common Lisp re-implementation of the Rails routes system for mapping URLs.

A client for the Stripe payment API.

This is an interface to the git binary to make controlling it from within Common Lisp much easier. It might not ever reach full coverage of all features given git's immense size, but features will be added as they are needed. The low-level command API is fully mapped however.

This package provides an implementation of the which UNIX command in Common Lisp.

Manual translation from C to Common Lisp of some random number generation functions from the GSL library.

Additional dolist style macros for Common Lisp, such as doalist, dohash, dolist*, doplist, doseq and doseq*.

This Common Lisp library provides function to make QR codes and to save them as PNG files.

This package implements The MD5 Message-Digest Algorithm, as defined in RFC 1321 by R. Rivest, published April 1992.

cl-random is a library for generating random draws from various commonly used distributions, and for calculating statistical functions, such as density, distribution and quantiles for these distributions.

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

BOOST-JSON is a simple JSON parsing library for Common Lisp.

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.

The py-configparser package implements the ConfigParser Python module functionality in Common Lisp. In short, it implements reading and writing of .INI-file style configuration files with sections containing key/value pairs of configuration options. In line with the functionalities in the python module, does this package implement basic interpolation of option values in other options.

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.
