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 library provides a simple multithreading worker mechanism.

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

cl-num-utils implements simple numerical functions for Common Lisp, including:

• num=, a comparison operator for floats

• simple arithmeric functions, like sum and l2norm

• elementwise operations for arrays

• intervals

• special matrices and shorthand for their input

• sample statistics

• Chebyshev polynomials

• univariate rootfinding

This package provides a PNG Common Lisp system to operate with Portable Network Graphics file format.

This is a binding to the libyaml library. It's not meant as a full library for YAML, just a bare binding with a couple of utility macros. For a YAML parser and emitter using this, check out cl-yaml.

This package provides Common Lisp bindings to the pango text layout library.

This package provides tools for manipulating data in files using data frames.

Portable Threads (and Scheduled and Periodic Functions) API for Common Lisp (from GBBopen project).

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 library for reading semi-raw user input from terminals. Semi-raw as in, we can't detect if the user pressed the Control key alone, and the function keys are a mystery. What is supported, however, is:

• Regular characters

• Control+[key]

• Alt+[key]

• Control+Alt+[key]

cl-template is a template engine for Common Lisp, taking inspiration from Ruby's ERb module.

This package provides a grab bag of miscellaneous Common Lisp utilities.

Command-Line-Args provides a main macro (command) that wraps a defun form and creates a new function that parses the command line arguments. It has support for command-line options, positional, and variadic arguments. It also generates a basic help message. The interface is meant to be easy and non-intrusive.

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.

CL-HEAP provides various implementations of heap data structures (a binary heap and a Fibonacci heap) as well as an efficient priority queue.

This library is a portable compatibility layer around "Common Lisp the Language, 2nd Edition" (https://www.cs.cmu.edu/Groups/AI/html/cltl/clm/node102.html) and it exports symbols from implementation-specific packages.

The cl-sqlite package is an interface to the SQLite embedded relational database engine.

This package provides a JSON-RPC 2.0 server/client for Common Lisp.

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

This is ZS3, a library for working with Amazon's Simple Storage Service (S3) and CloudFront service from Common Lisp.

This package provides a consolidation of Common Lisp statistics libraries.

XSubseq provides functions to be able to handle "subseq"s more effieiently.

This package provides a KDL reader/writer for Common Lisp.
