The 3d-math library implements types, operators, and algorithms commonly used in math for 2D and 3D graphics. It supersedes and combines the prior libraries 3d-vectors, 3d-matrices, 3d-quaternions, and 3d-transforms. The new API is largely but not entirely backwards compatible, and adds new functionality.

Fast-io is about improving performance to octet-vectors and octet streams (though primarily the former, while wrapping the latter).

HTML parser/emitter for CommonDoc.

This package provides the terminal-size:size function to get the size of the terminal from Common Lisp.

This is a Common Lisp kernel for Jupyter along with a library for building Jupyter kernels, based on Maxima-Jupyter which was based on cl-jupyter.

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.

This is a bare-bones Permuted Congruential Generator implementation in pure Common Lisp.

This package provides a noise library for Common Lisp.

This library provides an asynchronous process execution mechanism for Common Lisp.

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.

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

cl-charms is an interface to libcurses in Common Lisp. It provides both a raw, low-level interface to libcurses via CFFI, and a more higher-level lispier interface.

This is a library for access to atomic operation primitives such as compare-and-swap. It aims to be a rather thin layer over what the implementations offer.

This package provides a set of bindings and utilities for accessing the OpenGL (Mesa), GLU and GLUT (FreeGLUT) APIs using CFFI.

This is a minimalistic parser of command line options. The main advantage of the library is the ability to concisely define command line options once and then use this definition for parsing and extraction of command line arguments, as well as printing description of command line options (you get --help for free). This way you don't need to repeat yourself. Also, unix-opts doesn't depend on anything and precisely controls the behavior of the parser via Common Lisp restarts.

DEFLATE data, defined in RFC1951, forms the core of popular compression formats such as zlib (RFC 1950) and gzip (RFC 1952). As such, Chipz also provides for decompressing data in those formats as well. BZIP2 is the format used by the popular compression tool bzip2.

This is a Common Lisp version of UglifyJS, a JavaScript compressor. It works on data produced by parse-js to generate a minified version of the code. Currently it can:

• reduce variable names (usually to single letters)

• join consecutive var statements

• resolve simple binary expressions

• group most consecutive statements using the sequence operator (comma)

• remove unnecessary blocks

• convert IF expressions in various ways that result in smaller code

• remove some unreachable code

CXML does an excellent job at parsing XML elements, but what do you do when you have a XML file that's larger than you want to fit in memory, and you want to extract some information from it? Writing code to deal with SAX events, or even using Klacks, quickly becomes tedious. cl-xmlspam (for XML Stream PAttern Matcher) is designed to make it easy to write code that mirrors the structure of the XML that it's parsing. It also makes it easy to shift paradigms when necessary - the usual Lisp control constructs can be used interchangeably with pattern matching, and the full power of CXML is available when necessary.

This system is an implementation of the Common Lisp type system; particularly cl:typep and cl:subtypep.

This Common Lisp library provides utilities for the Bodge library collection.

This is a library for representing and mapping colours between their various spaces.

cl-syslog is a Common Lisp library that provides access to the syslog logging facility.

Cl-tga was written to facilitate loading .tga files into OpenGL programs. It's a very simple library, and, at the moment, only supports non-RLE encoded forms of the files.

This package provides an extensible implementation of defclass that can accurately control the expansion according to the metaclass and automatically detect the suitable metaclass by analyzing the defclass form.
