nontrivial-gray-streams is a compatibility system for Gray streams, which is an extension to Common Lisp that makes it possible to implement Common Lisp streams using generic functions.

This piece of code sets up some reader macros that make it simpler to input string literals which contain backslashes and double quotes This is very useful for writing complicated docstrings and, as it turns out, writing code that contains string literals that contain code themselves.

Enables fast and convenient interoperation with foreign objects.

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 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 a Common Lisp library to parse HTML5 documents.

CL-FastCGI is a generic version of SB-FastCGI, targeting to run on mostly Common Lisp implementation.

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

3bz is an implementation of Deflate decompression (RFC 1951) optionally with zlib (RFC 1950) or gzip (RFC 1952) wrappers, with support for reading from foreign pointers (for use with mmap and similar, etc), and from CL octet vectors and streams.

CL-HEAP provides various implementations of heap data structures (a binary heap and a Fibonacci heap) as well as an efficient priority queue.

simple-neural-network is a Common Lisp library for creating, training and using basic neural networks. The networks created by this library are feedforward neural networks trained using backpropagation.

DIFF is a package for computing various forms of differences between blobs of data and then doing neat things with those differences. Currently diff knows how to compute three common forms of differences: "unified" format diffs, "context" format diffs, and "vdelta" format binary diffs.

This is a collection of common cryptography functions for Common Lisp.

In the crowded space of Common Lisp HTML generators, Spinneret occupies the following coordinates:

• Modern. Targets HTML5. Does not treat XML and HTML as the same problem. Assumes you will be serving your documents as UTF-8.

• Composable. Makes it easy to refactor HTML generation into separate functions and macros.

• Pretty. Treats HTML as a document format, not a serialization. Output is idiomatic and readable, following the coding style of the HTML5 specification.

• Aggressive. If something can be interpreted as HTML, then it will be, meaning that some Lisp forms can't be mixed with HTML syntax. In the trade-off between 90% convenience and 10% correctness Spinneret is on the side of convenience.

• Bilingual. Spinneret (after loading spinneret/ps) has the same semantics in Lisp and Parenscript.

TRIVIAL-TYPES provides missing but important type definitions such as PROPER-LIST, ASSOCIATION-LIST, PROPERTY-LIST and TUPLE.

PAX provides an extremely poor man's Explorable Programming environment. 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). See how to enable some fanciness in Emacs Integration. Generating documentation from sections and all the referenced items in Markdown or HTML format is also implemented.

With the simplistic tools provided, one may accomplish similar effects as with Literate Programming, but documentation is generated from code, not vice versa and there is no support for chunking yet. Code is first, code must look pretty, documentation is code.

The 3D-Spaces library implements a number of spatial query data structures; structures that can answer spatial range queries for optimized lookup, particularly suited for games.

MODULARIZE is an attempt at providing a common interface to segregate major application components. This is achieved by adding special treatment to packages. Each module is a package that is specially registered, which allows it to interact and co-exist with other modules in better ways. For instance, by adding module definition options you can introduce mechanisms to tie modules together in functionality, hook into each other and so on.

This is a Gettext-style internationalisation framework for Common Lisp.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and UTM (Universal Transverse Mercator) or UPS (Universal Polar Stereographic).

This is a Common Lisp autowrapping facility for quickly creating clean and lean bindings to C libraries.

A CLOS class that defines callable objects whose behavior is similar to closures but adds conveniences such as introspectability.

A library for encoding text in various web-savvy encodings.

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