HTML-TEMPLATE is a Common Lisp library which can be used to fill templates with arbitrary (string) values at runtime. The result does not have to be HTML.

It is loosely modeled after the Perl module HTML::Template and partially compatible with a its syntax, though both libraries contain some extensions that the other does not support.

HTML-TEMPLATE translates templates into efficient closures which can be re-used as often as needed. It uses a cache mechanism so you can update templates while your program is running and have the changes take effect immediately.

This library is a universal interface to the operating system package manager. It has extensive support for Guix, among others:

• package listing and searching;

• package installation and uninstallation;

• package file listing;

• profile listing;

• manifest listing and installation;

• generation listing, switching and deletion.

BORDEAUX-THREADS is a proposed standard for a minimal MP/Threading interface. It is similar to the CLIM-SYS threading and lock support.

On Cliki.net <http://www.cliki.net/Common%20Lisp%20Utilities>, there is a collection of Common Lisp Utilities, things that everybody writes since they're not part of the official standard. There are some very useful things there; the only problems are that they aren't implemented as well as you'd like (some aren't implemented at all) and they aren't conveniently packaged and maintained. It takes quite a bit of work to carefully implement utilities for common use, commented and documented, with error checking placed everywhere some dumb user might make a mistake.

This package provides Python style generators for Common Lisp. It also includes a port of itertools.

This package provides a flexible shallow/deep copy mechanism for Common Lisp.

Library to fuzzily parse time and date strings into a universal-time timestamp.

This package provides a general-purpose connection pooling library for Common Lisp.

This package provides a simple yet powerful value inheritance scheme.

core-gp is a Common Lisp library for genetic programming (GP) algorithms. It allows standard GP, strongly-typed GP, grammatical evolution as well as standard genetic algorithms.

This data structure can be used to store the history of visited paths or URLs with a file or web browser, in a way that no “forward” element is ever forgotten.

The history tree is “global” in the sense that multiple owners (e.g. tabs) can have overlapping histories. On top of that, an owner can spawn another one, starting from one of its nodes (typically when you open a URL in a new tab).

This package provides an automatic generator for ASDF's .asd files.

Eager Future2 is a Common Lisp library that provides composable concurrency primitives that unify parallel and lazy evaluation, are integrated with the Common Lisp condition system, and have automatic resource management.

Xmls is a self-contained, easily embedded parser that recognizes a useful subset of the XML spec. It provides a simple mapping from XML to Lisp structures or s-expressions and back.

The main purpose of this n+2nd reimplementation of quasiquote is enable matching of quasiquoted patterns, using Optima or Trivia.

This package provides a generic cache management facility with configurable and extensible cache replacement policies. The actual cached data can be stored anywhere, with cacle taking charge of keeping track of which entry is to be discarded next when more space is needed for a new entry.

This package provides Common Lisp bindings to POSIX message queue, an IPC method that is easy to use and quick to setup.

F2cl is a Common Lisp library that can convert Fortran 77 code into Common Lisp code.

Inquisitor is a cross-implementation library providing encoding/end-of-line detection and external-format abstraction for Common Lisp.

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.

cl-cron is a simple tool that provides cron like facilities directly inside of Common Lisp.

This package is a list manipulation library for Common Lisp inspired by Haskell package Data.List.

This package provides a DSL for array slices in Common Lisp.

This is a Common Lisp implementation of the MessagePack (http://msgpack.org/) serialization/deserialization format, implemented according to http://wiki.msgpack.org/display/MSGPACK/Format+specification.
