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

UBIQUITOUS is a very easy-to-use library for persistent configuration storage. It automatically takes care of finding a suitable place to save your data, and provides simple functions to access and modify the data within.

Support library for numcl that provides Julia-like runtime parametric type correctness in Common Lisp. It is based on CLtL2 extensions.

Convenient macros for common lambda patterns.

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

CEPL (Code Evaluate Play Loop ) is a lispy and REPL-friendly Common Lisp library for working with OpenGL.

Its definition of success is making the user feel that GPU programming has always been part of the languages standard.

The usual approach to using CEPL is to start it at the beginning of your Lisp session and leave it open for the duration of your work. You can then treat the window it creates as just another output for your graphics, analogous to how *standard-output* is treated for text.

Moira is a library for monitoring and, if necessary, restarting long-running threads. In principle, it is like an in-Lisp process supervisor.

This package implements a simple interface for using WebSockets via Common Lisp.

PARSER-COMBINATORS is a library implementing monadic parser combinators in Common Lisp, similar in concept to Haskell Parsec system.

This package provides a Common Lisp implementation of Base64 encoding and decoding. Base64 encoding is a technique to encode binary data in a portable, safe printable, 7-bit ASCII format.

Parse-js is a Common Lisp package for parsing JavaScript (ECMAScript 3). It has basic support for ECMAScript 5.

Babel is a charset encoding and decoding library, not unlike GNU libiconv, but completely written in Common Lisp.

VAS-STRING-METRICS provides the Jaro, Jaro-Winkler, Soerensen-Dice, Levenshtein, and normalized Levenshtein string distance/similarity metrics algorithms.

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.

CHRONICITY is Common Lisp natural language date and time parser inspired by Ruby's Chronic.

ALEXA is a tool similar to lex or flex for generating lexical analyzers. Unlike tools like lex, however, ALEXA defines a domain-specific language within your Lisp program, so you don't need to invoke a separate tool.

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.

This library provides almost the same code as used inside Quicklisp for drawning progress bars

postmodern is a Common Lisp library for interacting with PostgreSQL databases. It provides the following features:

• Efficient communication with the database server without need for foreign libraries.

• Support for UTF-8 on Unicode-aware Lisp implementations.

• A syntax for mixing SQL and Lisp code.

• Convenient support for prepared statements and stored procedures.

• A metaclass for simple database-access objects.

This package produces 4 systems: postmodern, cl-postgres, s-sql, simple-date

SIMPLE-DATE is a very basic implementation of date and time objects, used to support storing and retrieving time-related SQL types. It is not loaded by default and you can use local-time (which has support for timezones) instead.

S-SQL is used to compile s-expressions to strings of SQL code, escaping any Lisp values inside, and doing as much as possible of the work at compile time.

CL-POSTGRES is the low-level library used for interfacing with a PostgreSQL server over a socket.

POSTMODERN itself is a wrapper around these packages and provides higher level functions, a very simple data access object that can be mapped directly to database tables and some convenient utilities. It then tries to put all these things together into a convenient programming interface

This package provides a DSL for array slices in Common Lisp.

This is a Common Lisp library providing various utilities.

In Common Lisp, a special variable that is never dynamically bound typically serves as a stand-in for a global variable. The global-vars library provides true global variables that are implemented by some compilers. An attempt to rebind a global variable properly results in a compiler error. That is, a global variable cannot be dynamically bound.

Global variables therefore allow us to communicate an intended usage that differs from special variables. Global variables are also more efficient than special variables, especially in the presence of threads.

Parse INI formatted files into a Common Lisp list structure.

This package provides Python style generators for Common Lisp. It also includes a port of itertools.
