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

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.

This library contains a collection of machine learning algorithms for online linear classification written in Common Lisp.

CL-random-forest is an implementation of Random Forest for multiclass classification and univariate regression written in Common Lisp. It also includes an implementation of Global Refinement of Random Forest.

This is a very simple implementation of SHA1 and HMAC-SHA1 for Common Lisp. The code is intended to be easy to follow and is therefore a little slower than it could be.

Croatoan provides high-level Common Lisp CLOS bindings for the ncurses terminal library.

Converts Markdown text into CommonDoc nodes and vice versa.

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

BST is a Common Lisp library for working with binary search trees that can contain any kind of values.

One of the many things that didn't quite get into the Common Lisp standard was how to get a Lisp to output its call stack when something has gone wrong. As such, each Lisp has developed its own notion of what to display, how to display it, and what sort of arguments can be used to customize it. trivial-backtrace is a simple solution to generating a backtrace portably.

This is a library for quaternions. It contains most of the quaternion operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable. It also tries to be efficient where plausible. Each quaternion is made up of floats, which by default are single-floats, as they do not require value boxing on most modern systems and compilers.

repl-utilities is a set of utilities which ease life at the REPL. It includes three sorts of features: introspective procedures, miscellaneous utility functions, and, pulling them together, methods to conveniently keep these symbols and optionally additional symbols available in whichever package you switch to.

Coalton is a dialect of ML embedded in Common Lisp. It emphasizes practicality and interoperability with Lisp, and is intended to be a DSL that allows one to gradually make their programs safer.

assoc-utils provides utilities for manipulating association lists in Common Lisp.

clingon is a command-line option parsing library for Common Lisp. Its features include:

• Support for subcommands

• Support for command aliases

• Support for short and long options

• Related options may be grouped into categories

• Short options may be collapsed into a single argument, as in -xyz

• Long options support the notations --long-opt arg and --long-opt=arg

• Automatic generation of help/usage information for commands and subcommands

• Out-of-the-box support for --version and --help

• Support for various kinds of options including string, integer, boolean, switch, enum, list, counter, filepath, etc.

• Subcommands can look up global options defined in parent commands

• Support for required options

• Options can be initialized via environment variables

• Single interface for creating options using CLINGON:MAKE-OPTION

• Generate documentation for your command-line application

• Support for pre-hook and post-hook actions for commands, which allow invoking functions before and after the respective handler of the command is executed

• Support for Bash and Zsh completions

• Extensibility, so if you don't find something you need you can extend it by developing a new option kind, or even a new mechanism for initializing options, e.g., by looking up an external key/value store

This package provides an interface to the gnuplot plotting utility. The intention of the API is to resemble to some of the plot commands of octave or matlab.

This library is a Common Lisp port of all the constants from the event codes header file found on Linux and FreeBSD.

This is a Common Lisp library for reading and printing MIME content. It supports automatic conversion between 7-bit, quoted-printable and base64 encodings.

DATA-SIFT is a Common Lisp data validation and transformation library inspired by cl-data-format-validation and WTForms validators.

This is a system for two dimensional computational geometry for Common Lisp.

Note: the system assumes exact rational arithmetic, so no floating point coordinates are allowed. This is not checked when creating geometric objects.

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

Funds provides portable, purely functional data structures in Common Lisp. It includes tree based implementations for Array, Hash, Queue, Stack, and Heap.

Enables fast and convenient interoperation with foreign objects.

This package provides easy access to the defining class and its options during initialization or reinitialization of its subcomponents.
