This library can be used to display a progress bar on one line.

This package provides a priority queue implemented with an array-based heap.

There are plenty of Lisp Markup Languages out there - every Lisp programmer seems to write at least one during his career - and CL-WHO (where WHO means "with-html-output" for want of a better acronym) is probably just as good or bad as the next one.

Trivial-Benchmark runs a block of code many times and outputs some statistical data for it. On SBCL this includes the data from time, for all other implementations just the real-time and run-time data. However, you can extend the system by adding your own metrics to it, or even by adding additional statistical computeations.

This is a very simple color library for Common Lisp, providing

• Types for representing colors in HSV and RGB spaces.

• Simple conversion functions between the above types (and also hexadecimal representation for RGB).

• Some predefined colors (currently X11 color names – of course the library does not depend on X11).Because color in your terminal is nice.

This library is no longer supported by its author.

GECO (Genetic Evolution through Combination of Objects) is an extensible, object-oriented framework for prototyping genetic algorithms in Common Lisp.

FARE-MOP is a small collection of utilities using the MetaObject Protocol. It notably contains a SIMPLE-PRINT-OBJECT method, and a SIMPLE-PRINT-OBJECT-MIXIN mixin that allow you to trivially define PRINT-OBJECT methods that print the interesting slots in your objects, which is great for REPL interaction and debugging.

The main purpose of this n+2nd reimplementation of quasiquote is enable matching of quasiquoted patterns, using Optima or Trivia.

This is a simple library to retrieve the argument list of a function.

CL-MOUNT-INFO is a Common Lisp wrapper around getmntent(3) and related C functions to get information about the mounted file system.

This package provides a PEM (Privacy-Enhanced Mail) parser for Common Lisp.

This package extends the Common Lisp reader syntax such that is accepts Org files as Lisp source code files.

This package provides a UTF-8 string input stream over a binary stream for Common Lisp.

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.

Dynamic-Classes helps to ease the prototyping process by bringing dynamism to class definition.

CLML (Common Lisp Machine Learning) is a high performance and large scale statistical machine learning package

This package provides a general-purpose connection pooling library for Common Lisp.

This is a backend for the linear-programming Common Lisp library using the GNU Linear Programming Kit (GLPK) library.

SPECIALIZATION-STORE system provides a new kind of function, called a store function, whose behavior depends on the types of objects passed to the function.

This package is a simple date and time library.

This package implements binary trees of various kinds, presenting a uniform interface to them all.

This is a Common Lisp library providing functions to read/write CSV from/to strings, streams and files.

Alternative to the compiler-macro library:

• Here, we do not treat compiler notes as warnings, but instead these are a separate class of conditions. These are also not errors.

• Two main condition classes are provided: compiler-macro-notes:note and compiler-macro-notes:optimization-failure-note. While the latter is a subclass of the former, the latter notes are printed in a slightly different manner to the former.

• To be able to correctly print the expansion path that led to the condition, user code is expected to avoid performing a nonlocal exit to a place outside with-notes.

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