This a Common Lisp library to convert geographic coordinates between latitude/longitude and Maidenhead locator system.

Common Lisp already has major 2 namespaces, function namespace and value namespace (or variable namespace), but there are actually more — e.g., class namespace. This library offers macros to deal with symbols from any namespace.

This package contains a few utility functions from the LispWorks library that are used in software such as ContextL.

This a Common Lisp library to parse HTML5 documents.

This package provides an ASN.1 encoder/decoder for Common Lisp.

ORG-SAMPLER allows using Lisp docstrings and reflection to make org-mode text for inclusion into a larger document.

This package parses and prints dates in RFC-1123 format.

This package defines a Common Lisp package, :elements, with an ELEMENT structure and a number of functions to search the periodic table.

This package provides a robust CSV parser and printer that tries to follow the fine print of de facto standards. It can be configured to choose which standard exactly.

Simple and fast marshalling of Lisp datastructures. Convert any object into a string representation, put it on a stream an revive it from there. Only minimal changes required to make your CLOS objects serializable.

This package provides audio input and output functions to Common Lisp using bindings to the portaudio library.

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.

Support library for numcl. Registers a function as an additional form that is considered as a candidate for a constant.

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.

generic-cl provides a generic function wrapper over various functions in the Common Lisp standard, such as equality predicates and sequence operations. The goal of this wrapper is to provide a standard interface to common operations, such as testing for the equality of two objects, which is extensible to user-defined types.

s-sysdeps is an abstraction layer over platform dependent functionality. This simple package is used as a building block in a number of other projects.

s-sysdeps abstracts:

• managing processes,

• implementing a standard TCP/IP server,

• opening a client TCP/IP socket stream,

• working with process locks.

trivial-garbage provides a portable API to finalizers, weak hash-tables and weak pointers on all major implementations of the Common Lisp programming language.

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

UFFI provides a universal foreign function interface (FFI) for Common Lisp.

This library provides modern file handling for Common Lisp, which avoids many of the pitfalls of pathnames.

This package provides a trivial line-input library for VT-like terminals.

KMRCL is a collection of utilities used by a number of Kevin Rosenberg's Common Lisp packages.

qbase64 provides a fast and flexible base64 encoder and decoder for Common Lisp.

This package provides a hierarchy of major functions and auxiliary functions related to the structured analysis and processing of open text.
