Dynamic-Classes helps to ease the prototyping process by bringing dynamism to class definition.

This package provides a framework to unify arbitrary Common Lisp objects while constructing bindings for placeholders (unification variables) in a template sublanguage.

This collection of utilities is useful in contexts where you want a macro that uses lambda-lists in some fashion but need more precise processing.

This package provides first-class global environments for Common Lisp.

Various ASDF extensions such as attached test and documentation system, explicit development support, etc.

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

This Common Lisp library provides functions for lzip (LZMA) compression/decompression using bindings to the lzlib C library.

CL-DEBUG provides a unified way to enable or disable debug-specific code. Debugging code can be enabled or disabled relative to program features denoted by either a symbol or a keyword.

This library is a Common Lisp port of all the constants from the event codes header file found on Linux and FreeBSD.

This library provides payment API wrappers over BTCPay, Paypal, and Stripe.

It can sometimes be useful to be able to parse chemical compounds in a user-friendly syntax into easy-to-manipulate s-expressions. You also want to be able to go in reverse. You could probably write your own parser — or you could just install the chemical-compounds package.

ZPB-TTF is a TrueType font file parser that provides an interface for reading typographic metrics, glyph outlines, and other information from the file.

cl-dotenv is a utility library for loading .env files in Common Lisp.

Overlord is a build system in Common Lisp. It is a real build system, with all the modern features: rules with multiple outputs, parallel builds, immunity to clock issues, and dynamic dependencies.

But Overlord is more than another build system. Overlord is a uniform approach to dependencies inside or outside of a Lisp image. Overlord is to Make what Lisp macros are to C macros.

Overlord is designed to be used from the Lisp REPL. A command line interface is available in a separate repository. See https://github.com/ruricolist/overlord-cli.

This package provides a Common Lisp wrapper system for the SDL 2.0 C Library.

This is a bindings and wrapper library to libmpg123 allowing for convenient, extensive, and fast decoding of MPEG1/2/3 (most prominently mp3) files.

definitions-systems provides a simple unified extensible way of processing named definitions.

This package provides Common Lisp support for reading the Terragen .TER format. The format specification can be found at https://planetside.co.uk/wiki/index.php?title=Terragen_.TER_Format

This package provides a Common Lisp system which wraps the BORDEAUX-THREADS system to be able to run things in the main thread of the implementation, for example drawing calls of GUI applications.

Quickproject provides a quick way to make a Common Lisp project. After creating a project, it extends the ASDF registry so the project may be immediately loaded.

Osicat is a lightweight operating system interface for Common Lisp on Unix-platforms. It is not a POSIX-style API, but rather a simple lispy accompaniment to the standard ANSI facilities.

This library contains a lexer for syntaxes that use shell-like rules for quoting and commenting. It is a port of the shlex module from Python’s standard library.
