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 library contains generic hacks meant to be used in any project. It was originally developed for the Cells library.

This package provides Common Lisp bindings to the pango text layout library.

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

The 3d-math library implements types, operators, and algorithms commonly used in math for 2D and 3D graphics. It supersedes and combines the prior libraries 3d-vectors, 3d-matrices, 3d-quaternions, and 3d-transforms. The new API is largely but not entirely backwards compatible, and adds new functionality.

Use rich-formatter to format documentation with sections :syntax, :arguments, :examples, :description, :returns, :side-effects, :thread-safety, :affected-by, :see-also and :notes. Gather unformatted input by using rich-aggregating-formatter and *DOCUMENTATION* variable. Find gathered documentation with find-documentation function. Execute code stored in documentation with execute-documentation. See the examples in the src/documentation.lisp file. See the documentation-utils system for more information.

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

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 an implementation of the hash-set data structure. It has constant time lookup, insertion and deletion.

bubble-operator-upwards is a function that bubbles an operator upwards in a form, demultiplexing all alternative branches by way of cartesian product.

deeds allows for efficient event delivery to multiple handlers with a complex event filtering system.

Feeder is a syndication feed library. It presents a general protocol for representation of feed items, as well as a framework to translate these objects from and to external formats. It also implements the RSS 2.0 and Atom formats within this framework.

This package provides a collection of types, functions and macros. Some of the functionality is implemented from Graham's On Lisp and Seibel's Practical Common Lisp.

TRIVIAL-OCTET-STREAMS is a Common Lisp library implementing in-memory octet streams analogous to string streams.

This is a client library to interact with the "mod.io" (https://mod.io) platform to manage "mods" or extensions for games and other applications. It covers the full v1 API and includes convenience methods to make interacting with the API as well as syncing mods and so on easy.

This package is a geospatial library, based on cl-wkb, that implements the OGC Well-Known Binary geographic geometry data model with PostGIS 3d, 4d extensions, and provides WKB and EWKB encoding and decoding functionality.

iterate is an iteration construct for Common Lisp. It is similar to the CL:LOOP macro, with these distinguishing marks:

• it is extensible,

• it helps editors like Emacs indent iterate forms by having a more lisp-like syntax, and

• it isn't part of the ANSI standard for Common Lisp.

This package provides an implementation of the which UNIX command in Common Lisp.

Chunga implements streams capable of chunked encoding on demand as defined in RFC 2616.

This Common Lisp library contains the core classes and pixel access macros for the Opticl image processing library.

This library provides a macroexpand-all function that calls the implementation specific equivalent.

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.

Authentic provides a light-weight and extendible solution to user/password management for Common Lisp applications. It has features such as safe password storage in a database, password reset, user confirmation tokens, and user authentication.

This package provides a client for SMTP.
