KMRCL is a collection of utilities used by a number of Kevin Rosenberg's Common Lisp packages.
Birch is a simple Common Lisp IRC client library. It makes use of CLOS for event handling.
cl-azure provides a library to access Microsoft Windows Azure cloud services from Common Lisp.
Babel is a charset encoding and decoding library, not unlike GNU libiconv, but completely written in Common Lisp.
Clack is a web application environment for Common Lisp inspired by Python's WSGI and Ruby's Rack.
This Common Lisp library provides functions for lzip (LZMA) compression/decompression using bindings to the lzlib C library.
This package provides a Common Lisp testing framework system CACAU which was built to be independent of assertions systems.
This is a Common Lisp library consisting of a collection of useful GPU shader functions, written with Shadow.
This package provides a Common Lisp templating system based on Python Django with a syntax similar to Python Jinja2.
This system is an implementation of the Common Lisp type system; particularly cl:typep and cl:subtypep.
cl-mondo is a simple Common Lisp REPL, just like the SLIME REPL that works on the terminal.
Support library for numcl that provides Julia-like runtime parametric type correctness in Common Lisp. It is based on CLtL2 extensions.
This package provides Common Lisp bindings to access the linear algebra libraries using the CBLAS API. Currently the OpenBLAS implementation is used.
Funds provides portable, purely functional data structures in Common Lisp. It includes tree based implementations for Array, Hash, Queue, Stack, and Heap.
This package provides a compute-effective-slot-definition-initargs generic function that allows for more ergonomic initialization of effective slot definition objects.
Moira is a library for monitoring and, if necessary, restarting long-running threads. In principle, it is like an in-Lisp process supervisor.
Forge is a generic build system. Refer to documentation for the specific kind of project you're building to get the full picture.
Cells is a mature, stable extension to CLOS allowing one to create classes whose instances can have slot values determined by instance-specific formulas.
cl-mssql provides an interface to connect to Microsoft SQL server. It uses the libsybdb foreign library provided by the FreeTDS project.
This Common Lisp library converts strings, symbols and keywords between any of the following typographical cases: PascalCase, camelCase, snake_case, kebab-case (lisp-case).
ADOPT is a simple UNIX-style option parser in Common Lisp, heavily influenced by Python's optparse and argparse.
This is a trivial utility for distinguishing between a process running in a real terminal window and a process running in a dumb one, e.g. emacs-slime.
The GRAPH Common Lisp library provides a data structures to represent graphs, as well as some graph manipulation and analysis algorithms (shortest path, maximum flow, minimum spanning tree, etc.).
