3D-MATRICES is a library implementing common matrix operations, mainly intended as the counterpiece to 3d-vectors and thus being aimed at operations in 3D space.

Parse-Declarations is a Common Lisp library to help writing macros which establish bindings. To be semantically correct, such macros must take user declarations into account, as these may affect the bindings they establish. Yet the ANSI standard of Common Lisp does not provide any operators to work with declarations in a convenient, high-level way. This library provides such operators.

The Common Foreign Function Interface (CFFI) purports to be a portable foreign function interface for Common Lisp. The CFFI library is composed of a Lisp-implementation-specific backend in the CFFI-SYS package, and a portable frontend in the CFFI package.

cl-draw-cons-tree draws a cons tree in ASCII-art style.

This library contains code that implements Common Lisp hash tables.

This is a Common Lisp library to enable simple message pipelines.

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.

ORG-SAMPLER allows using Lisp docstrings and reflection to make org-mode text for inclusion into a larger document.

A utility for running external programs, built on UIOP. Cmd is designed to be natural to use, protect against shell interpolation and be usable from multi-threaded programs.

This is a Common Lisp library providing lambda shorthand macros aiming to be used in cases where the word lambda and the arguments are longer than the body of the lambda.

This is a Common Lisp Markdown to HTML converter, using esrap for parsing, and grammar based on peg-markdown.

Smart-buffer provides an output buffer which changes the destination depending on content size.

This library enable rapid file search, inspection and manipulation straight from the REPL. It aims at replacing Unix tools such as find or du. It also offers a replacement to the pathname Common Lisp API. Slot writers which commit changes to disk, e.g. permissions, modification time, etc.

Bobbin is a simple word-wrapping library for strings in Common Lisp. It aims to be simple, work nicely for the majority of cases, and degrade gracefully for edge cases. It is not particularly concerned with speed — if you need very high-performance word wrapping, Bobbin is not for you.

A mixture of features from eRuby and HTML::Template. You could name it "Yet Another LSP" (LispServer Pages) but it's a bit more than that and not limited to a certain server or text format.

This is a library to find system font files. It works on systems with FontConfig on Linux, BSD. It does not have any foreign dependencies that aren't already directly available on the system.

UFFI provides a universal foreign function interface (FFI) for Common Lisp.

The LOCAL-TIME library is a Common Lisp library for the manipulation of dates and times. It is based almost entirely upon Erik Naggum's paper "The Long Painful History of Time".

one-more-re-nightmare is a regular expression engine that uses the technique presented in Regular-expression derivatives re-examined (Owens, Reppy and Turon, 2009; doi:10.1017/S0956796808007090) to interpret and compile regular expressions.

The Type-Templates library allows you to define types and “template functions” that can be expanded into various type-specialized versions to eliminate runtime dispatch overhead. It was specifically designed to implement low-level numerical data types and functionality.

This package provides a library for parsing MIME types, in the spirit of http://code.google.com/p/mimeparse/, with a Common Lisp flavor.

string-pokemonize provides a function that alternates uppercase and lowercase characters for a given string.

CL-PPCRE is a portable regular expression library for Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

40ants-doc provides a rudimentary explorable programming environment. The 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). Generating documentation in Markdown or HTML format from sections and all the referenced items is also implemented.

With the simplistic tools provided, one may obtain results similar to literate programming, but documentation is generated from code, not the other way around, and there is no support for chunking. Code comes first, code must look pretty, documentation is code.

40ants-doc is a fork of MGL-PAX with fewer dependencies (only named-readtables and pythonic-string-reader) for the core system, and additional features in the full system.
