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.

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

Portability library for IEEE float features that are not covered by the Common Lisp standard.

CF is a Common Lisp library for doing computations using continued fractions.

This Common Lisp library provides an implementation of in-memory input streams, output streams and io streams for any type of elements.

This package provides a Common Lisp system implementing event bus.

cl-transmission is a library to interface with the Transmission torrent client using its RPC (remote procedure call).

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.

Hunchentoot is a web server written in Common Lisp and at the same time a toolkit for building dynamic websites. As a stand-alone web server, Hunchentoot is capable of HTTP/1.1 chunking (both directions), persistent connections (keep-alive), and SSL.

This Common Lisp library provides reader macros for concise expression of function partial application and composition.

Splits sequence into a list of subsequences delimited by objects satisfying the test.

CL-DEBUG provides a unified way to enable or disable debug-specific code. Debugging code can be enabled or disabled relative to program features denoted by either a symbol or a keyword.

This library provides a modern project skeleton generator. In contract with other generators, CL-Project generates one package per file and encourages unit testing by generating a system for unit testing, so you can begin writing unit tests as soon as the project is generated.

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

This library tries to provide a way to detect what kind of type the given predicate is trying to check. This is different from inferring the return type of a function.

ADOPT is a simple UNIX-style option parser in Common Lisp, heavily influenced by Python's optparse and argparse.

This package provides Common Lisp bindings to GSSAPI, which is designed to provide a standard API to authentication services. The API itself is generic, and the system can provide different underlying implementations. The most common one is Kerberos, which has several implementations, the most common of which is probably Active Directory.

cl-template is a template engine for Common Lisp, taking inspiration from Ruby's ERb module.

This Common Lisp library provides a simple FIFO implementation with no external dependencies.

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 library provides GTK4 bindings for Common Lisp via Gobject Introspection, in the cl-gtk4 ASDF system.

This package provides a function to parse the PATH environment variable portably in Common Lisp.

This is an implementation of the Unicode Standards Annex #14 (http://www.unicode.org/reports/tr14/) line breaking algorithm. It provides a fast and convenient way to determine line breaking opportunities in text.

Note that this algorithm does not support break opportunities that require morphological analysis. In order to handle such cases, please consult a system that provides this kind of capability, such as a hyphenation algorithm.

Also note that this system is completely unaware of layouting decisions. Any kind of layouting decisions, such as which breaks to pick, how to space between words, how to handle bidirectionality, and what to do in emergency situations when there are no breaks on an overfull line are left up to the user.

Eazy-Gnuplot is a Common Lisp interface to gnuplot which eschews CFFI, CLOS and structures. It communicates with gnuplot via *standard-output*, and users can plot data by printing to that stream.
