Forge is a generic build system. Refer to documentation for the specific kind of project you're building to get the full picture.

This package provides simple format directives to print in colors.

This package provides a library to open a web browser to a URL.

Loop has a consistent interface unlike other looping abstractions and ANSI list operations. You can define your own efters and gatherers that integrate tightly into other operations. All operations are non-consing when possible.

This package provides CFFI binding to libmixed audio library for Common Lisp with support of other audio formats available on GNU/Linux systems:

• Alsa

• Jack

• Openmpt

• PulseAudio

• Flac (via CL-FLAC)

• Mpg123 (via CL-MPG123)

• Ogg/vorbis (via CL-VORBIS)

• Out123 (via CL-OUT123)

• WAV

System-Load is a Common Lisp library for accessing the system's CPU and memory usage.

This is a portable Universal Resource Identifier library for Common Lisp programs. It parses URI according to the RFC 2396 specification.

This package provides Common Lisp bindings to create OpenGL window and context manipulation code as well as system input handling. Direct FFI bindings to system functions are used so no third party C lib is required except system libraries.

Common Lisp comes with quite some functions to compare objects for equality, yet none is applicable in every situation and in general this is hard, as equality of objects depends on the semantics of operations on them. As consequence, users find themselves regularly in a situation where they have to roll their own specialized equality test.

This module provides one of many possible equivalence relations between standard Common Lisp objects. However, it can be extended for new objects through a simple CLOS protocol. The rules when two objects are considered equivalent distinguish between mutating and frozen objects. A frozen object is promised not to be mutated in the future in a way that operations on it can notice the difference.

We have chosen to compare mutating objects only for identity (pointer equality), to avoid various problems. Equivalence for frozen objects on the other hand is established by recursing on the objects' constituent parts and checking their equivalence. Hence, two objects are equivalent under the OBJECT= relation, if they are either identical, or if they are frozen and structurally equivalent, i.e. their constituents are point-wise equivalent.

Since many objects are potentially mutable, but are not necessarily mutated from a certain point in their life time on, it is possible to promise to the equivalence relation that they remain frozen for the rest of their life time, thus enabling coarser equivalence than the often too fine-grained pointer equality.

The Common Foreign Function Interface (CFFI) purports to be a portable foreign function interface for Common Lisp. The CFFI library is composed of a Lisp-implementation-specific backend in the CFFI-SYS package, and a portable frontend in the CFFI package.

NFiles is a Common Lisp library to help manage file persistence and loading, in particular user-centric files like configuration files. It boasts the following features:

• Dynamic and customizable path expansion.

• Extensible serialization and deserialization.

• Cached reads and writes. When a file object expands to the same path as another one, a read or write on it won’t do anything in case there was no change since last write.

• (Experimental!) On-the-fly PGP encryption.

• Profile support.

• On read error, existing files are backed up.

• On write error, no file is written to disk, the existing file is preserved.

OpenAPI client system generator.

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

cl-irc is a Common Lisp IRC client library that features (partial) DCC, CTCP and all relevant commands from the IRC RFCs (RFC2810, RFC2811 and RFC2812).

Features:

• implements all commands in the RFCs

• extra convenience commands such as op/deop, ban, ignore, etc.

• partial DCC SEND/CHAT support

• event driven model with hooks makes interfacing easy

• the user can keep multiple connections

• all CTCP commands

deeds allows for efficient event delivery to multiple handlers with a complex event filtering system.

FLARE is a library designed to allow quick and precise particle effect creations. It does not concern itself with displaying and only with the management and movement of particles. As such, it can easily be integrated into any existing or future application.

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.

ContextL is a CLOS extension for Context-Oriented Programming (COP).

Find overview of ContextL's features in an overview paper: http://www.p-cos.net/documents/contextl-soa.pdf. See also this general overview article about COP which also contains some ContextL examples: http://www.jot.fm/issues/issue_2008_03/article4/.

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.

40ants-doc provides a rudimentary explorable programming environment. The narrative primarily lives in so-called sections that mix Markdown docstrings with references to functions, variables, etc., all of which should probably have their own docstrings.

The primary focus is on making code easily explorable by using SLIME's M-. (slime-edit-definition). Generating documentation in Markdown or HTML format from sections and all the referenced items is also implemented.

With the simplistic tools provided, one may obtain results similar to literate programming, but documentation is generated from code, not the other way around, and there is no support for chunking. Code comes first, code must look pretty, documentation is code.

40ants-doc is a fork of MGL-PAX with fewer dependencies (only named-readtables and pythonic-string-reader) for the core system, and additional features in the full system.

This package provides a compute-effective-slot-definition-initargs generic function that allows for more ergonomic initialization of effective slot definition objects.

This package provides CFFI bindings to the libflac audio library for Common Lisp.

Just wrap your Common Lisp function in this macro call and it will be optimized for tail recursion. You will be warned if the function is not tail recursive.

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