cl-strings is a small, portable, dependency-free set of utilities that make it even easier to manipulate text in Common Lisp. It has 100% test coverage and works at least on sbcl, ecl, ccl, abcl and clisp.

This package provides an enhanced version of typep that is exactly like the one in the Lisp spec, except it can also accept a single type argument, in which case it returns the appropriate closure.

This is a library for access to atomic operation primitives such as compare-and-swap. It aims to be a rather thin layer over what the implementations offer.

Clack is a web application environment for Common Lisp inspired by Python's WSGI and Ruby's Rack.

This package exports the following function to parse floating-point values from a string in Common Lisp.

Wayflan is a from-scratch Wayland communication library for Common Lisp. It makes a good-faith effort to mimic libwayland behavior not defined in the Wayland spec, to keep compatibility between the two libraries.

Wayflan is not a compositor nor a GUI toolkit. Its purpose is to parse Wayland protocol XML documents and exchange Wayland messages between other processes.

Features:

• Client support

• All implementation done in Common Lisp from the socket up

• Enum values are translated into keywords

• Wayland protocol introspection

• ASDF component :wayflan-client-impl generates code from XML. ASDF's extensible components make it possible to teach your program new protocols for Wayland without the need of a special build system.

This package provides an enhanced version of typep that is exactly like the one in the Lisp spec, except it can also accept a single type argument, in which case it returns the appropriate closure.

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]

This package provides a Common Lisp system which has only one function to return the CPU count of the current system.

The Bordeaux-FFT library provides a reasonably efficient implementation of the Fast Fourier Transform and its inverse for complex-valued inputs, in portable Common Lisp.

This is a Common Lisp library for processing data found in dBase III database files (dbf and db3 files).

string-case is a Common Lisp macro that generates specialised decision trees to dispatch on string equality.

Antik provides a foundation for scientific and engineering computation in Common Lisp. It is designed not only to facilitate numerical computations, but to permit the use of numerical computation libraries and the interchange of data and procedures, whether foreign (non-Lisp) or Lisp libraries. It is named after the Antikythera mechanism, one of the oldest examples of a scientific computer known.

Simplified-Types is a library that provides functions for simplifying Common Lisp type specifiers. The API consists of two functions:

• simplify-type takes a type specifier and, optionally, an environment, and returns the corresponding simplified type.

• simplified-type-of takes an object and returns the simplified type of that object.

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

This Common Lisp library converts strings, symbols and keywords between any of the following typographical cases: PascalCase, camelCase, snake_case, kebab-case (lisp-case).

Agnostic Lizard is a portable implementation of a code walker and in particular of the macroexpand-all function (and macro) that makes a best effort to be correct while not expecting much beyond what the Common Lisp standard requires.

It aims to be implementation-agnostic and to climb the syntax trees.

Very basic library for dealing with CL's hash tables. The idea was spawned through working with enough JSON APIs and config files, causing a lot of headaches in the process.

Simple scheme to classify file types in a hierarchical fashion.

LMDB, the Lightning Memory-mapped Database, is an ACID key-value database with multiversion concurrency control. This package is a Common Lisp wrapper around the C LMDB library. It covers most of C LMDB's functionality, has a simplified API, much needed safety checks, and comprehensive documentation.

Markup allows the use of HTML syntax with in Common Lisp code. This has the advantage of being able to copy HTML snippets and have them instantly be functional, less double quotes than a s-expression approach, and designers will be able to understand the embedded HTML.

This library provides a uniform API, as specified in Common Lisp the Language 2, for accessing information about variable and function bindings from implementation-defined lexical environment objects. All major Common Lisp implementations are supported, even those which don't support the CLTL2 environment access API.

Py4CL is a bridge between Common Lisp and Python, which enables Common Lisp to interact with Python code. It uses streams to communicate with a separate python process, the approach taken by cl4py. This is different to the CFFI approach used by burgled-batteries, but has the same goal.

MGL-GPR is a library of evolutionary algorithms such as Genetic Programming (evolving typed expressions from a set of operators and constants) and Differential Evolution.
