S-XML is a simple XML parser implemented in Common Lisp. This XML parser implementation has the following features:

• It works (handling many common XML usages).

• It is very small (the core is about 700 lines of code, including comments and whitespace).

• It has a core API that is simple, efficient and pure functional, much like that from SSAX (see also http://ssax.sourceforge.net).

• It supports different DOM models: an XSML-based one, an LXML-based one and a classic xml-element struct based one.

• It is reasonably time and space efficient (internally avoiding garbage generatation as much as possible).

• It does support CDATA.

• It should support the same character sets as your Common Lisp implementation.

• It does support XML name spaces.

This XML parser implementation has the following limitations:

• It does not support any special tags (like processing instructions).

• It is not validating, even skips DTD's all together.

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 Common Lisp system which has only one function to return the CPU count of the current system.

This package provides an enhanced version of typep that is exactly like the one in the Lisp spec, except it can also accept a single type argument, in which case it returns the appropriate closure.

Simple scheme to classify file types in a hierarchical fashion.

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

Cluffer is a library for representing the buffer of a text editor. As such, it defines a set of CLOS protocols for client code to interact with the buffer contents in various ways, and it supplies different implementations of those protocols for different purposes.

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.

Opticl is a Common Lisp library for representing, processing, loading, and saving 2-dimensional pixel-based images.

CL-INTERPOL is a library for Common Lisp which modifies the reader so that you can have interpolation within strings similar to Perl or Unix Shell scripts. It also provides various ways to insert arbitrary characters into literal strings even if your editor/IDE doesn't support them.

The GNU Scientific Library for Lisp (GSLL) allows the use of the GNU Scientific Library (GSL) from Common Lisp. This library provides a full range of common mathematical operations useful to scientific and engineering applications. The design of the GSLL interface is such that access to most of the GSL library is possible in a Lisp-natural way; the intent is that the user not be hampered by the restrictions of the C language in which GSL has been written. GSLL thus provides interactive use of GSL for getting quick answers, even for someone not intending to program in Lisp.

Hunchentoot is a web server written in Common Lisp and at the same time a toolkit for building dynamic websites. As a stand-alone web server, Hunchentoot is capable of HTTP/1.1 chunking (both directions), persistent connections (keep-alive), and SSL.

This is a Common Lisp library that implements the 9p network filesystem protocol.

Radiance is a web application environment, which is sort of like a web framework, but more general, more flexible. It should let you write personal websites and generally deployable applications easily and in such a way that they can be used on practically any setup without having to undergo special adaptations.

The Plump-SEXP library is a backend for Plump which can convert between S-expressions and the Plump DOM.

This is a wrapper for the SDL2_TTF library used for loading fonts and creating text assets. The library, in it's current state, can load TTF and OTF fonts and render fonts with the three different rendering modes provided by the C library (solid, shaded, and blended). While Latin text, UTF8, UNICODE, and Glyph text rendering is available only Latin text has been tested (as shown in the examples).

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.

TRIVIAL-OCTET-STREAMS is a Common Lisp library implementing in-memory octet streams analogous to string streams.

The Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. Both Emacs and vi editing modes are available. The Readline library includes additional functions to maintain a list of previously-entered command lines, to recall and perhaps reedit those lines, and perform csh-like history expansion on previous commands.

Charje.documentation can used to parse Common Lisp docstrings the charje way, or it can be used to create custom docstring parsers. Docstring parsers are composed using mixin classes and initialization methods.

File-Notify is a Common Lisp library for getting notifications for file accesses and changes.

This is a Common Lisp library to present tabular data in ascii-art tables.

This package is a Python Numpy clone implemented in pure Common Lisp.

CMN provides a package of functions to hierarchically describe a musical score. When evaluated, the musical score is rendered to an image.
