This system is an implementation of the Common Lisp type system; particularly cl:typep and cl:subtypep.

This is a collection of common cryptography functions for Common Lisp.

This library implements the -> and ->> macros from Clojure, as well as several expansions on the idea.

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

This package provides data frames for Common Lisp, a two-dimensional array-like structure in which each column contains values of one variable and each row contains one set of values from each column.

QMyND, the QITAB MySQL Native Driver, is a MySQL client library that directly talks to a MySQL server in its native network protocol.

It's a part of QITAB umbrella project.

This package provides a common lisp CFFI wrapper for the SciPy version of Cephes special functions.

cl-change-case is a library to convert strings between camelCase, PascalCase, snake_case, param-case, CONSTANT_CASE and more.

This is a native Common Lisp graphics math library with an emphasis on performance and correctness.

This library contains code that implements Common Lisp hash tables.

trivial-clipboard gives access to the system clipboard.

Dexador is yet another HTTP client for Common Lisp with neat APIs and connection-pooling. It is meant to supersede Drakma.

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.

cl-cookie is a Common Lisp library featuring parsing of cookie headers, cookie creation, cookie jar creation and more.

CL-MOUNT-INFO is a Common Lisp wrapper around getmntent(3) and related C functions to get information about the mounted file system.

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.

Babel is a charset encoding and decoding library, not unlike GNU libiconv, but completely written in Common Lisp.

This library allows you to implement and enforce proper finalization of compile-time constructs while building Lisp source files.

It produces two systems: asdf-finalizers and list-of.

OpenAPI client system generator.

This library contains a collection of machine learning algorithms for online linear classification written in Common Lisp.

hdf5-cffi is a CFFI wrapper for the HDF5 library.

This package provides the CL-SVG Common Lisp system to produce Scalable Vector Graphics files.

This library is intended to solve the problem of source tracking for Common Lisp code.

By "source tracking", it is meant that code elements that have a known origin in the form of a position in a file or in an editor buffer are associated with some kind of information about this origin.

Since the exact nature of such origin information depends on the Common Lisp implementation and the purpose of wanting to track that origin, the library does not impose a particular structure of this information. Instead, it provides utilities for manipulating source code in the form of what is called concrete syntax trees (CSTs for short) that preserve this information about the origin.

simple-neural-network is a Common Lisp library for creating, training and using basic neural networks. The networks created by this library are feedforward neural networks trained using backpropagation.
