This package provides a Common Lisp library for fetching and parsing RSS feeds data via HTTP. Currently, it supports RSS versions 0.90, 0.91, and 0.92 as well as RSS version 2.

This package provides a SDL2 based vector graphic library for Common Lisp.

MODULARIZE is an attempt at providing a common interface to segregate major application components. This is achieved by adding special treatment to packages. Each module is a package that is specially registered, which allows it to interact and co-exist with other modules in better ways. For instance, by adding module definition options you can introduce mechanisms to tie modules together in functionality, hook into each other and so on.

This package provides Common Lisp system collecting tools written to wrangle OpenGL Shader Language (GLSL) source files.

Bind extends the idea of of let and destructing to provide a uniform syntax for all your accessor needs. It combines let, destructuring-bind, with-slots, with-accessors, structure editing, property or association-lists, and multiple-value-bind and a whole lot more into a single form.

This library defines most Common Lisp standard macros that can be defined in a portable way and that can generate portable code. Some of these macros may not be good enough as the final version for a typical implementation, but they will work.

File-Notify is a Common Lisp library for getting notifications for file accesses and changes.

The LOCAL-TIME library is a Common Lisp library for the manipulation of dates and times. It is based almost entirely upon Erik Naggum's paper "The Long Painful History of Time".

This package provides an example implementation of the Common Lisp condition system and library, based on the original condition system implementation by Kent M. Pitman.

dbi is a Common Lisp library providing a database independent interface for MySQL, PostgreSQL and SQLite.

This library retrieves locale information configured on the system. This is helpful if you want to write applications and libraries that display messages in the user's native language.

This package provides a library for parsing MIME types, in the spirit of http://code.google.com/p/mimeparse/, with a Common Lisp flavor.

This is a keymap facility for Common Lisp inspired by Emacsy (keymap.scm) which is inspired by Emacs.

• Support prefix keys to other keymaps. For instance, if you prefix my-mode-map with C-c, then all bindings for my-mode will be accessible after pressing C-c.

• List all bindings matching a given prefix. (Also known as which-key in Emacs.)

• List the bindings associated to a command.

• Support multiple inheritance.

• Support keycode.

• Validate keyspec at compile time.

• define-key can set multiple bindings in a single call.

• Support multiple scheme to make it easy to switch between, say, Emacs-style and VI-style bindings. This orthogonality to keymaps composes better than having multiple keymaps: changing scheme applies to the entire program, which is easier than looping through all keymaps to change them.

• Translate keyspecs as a fallback. For instance if shift-a is not bound, check A.

• Behaviour can be customized with global parameters such as *print-shortcut*.

• The compose function can merge multiple keymaps together.

• Support multiple arguments when that makes sense (e.g. multiple keymaps for lookup-key).

• Key remapping à-la Emacs.

• Typed keymaps, i.e. keymaps where bound values can only be of a given type. This is convenient to catch typos, for instance when binding 'FOO instead of #'FOO.

cl-alexandria-plus is a conservative set of extensions to cl-alexandria utilities.

Converts Markdown text into CommonDoc nodes and vice versa.

Optima is a fast pattern matching library which uses optimizing techniques widely used in the functional programming world.

This library is a redefinition of the standard Common Lisp package that includes a number of renames and shadows.

Triads is a simple command line tool that reads roman numeral notation from standard input (or a file) and an musical key and outputs the roman numeral in addition to the notes of the triad associated with that roman numeral given in the key.

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

hdf5-cffi is a CFFI wrapper for the HDF5 library.

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

This prompter library is heavily inspired by Emacs' minibuffer and Helm (https://emacs-helm.github.io/helm/). It only deals with the backend side of things, it does not handle any display. Features include asynchronous suggestion computation, multiple sources, actions and resumable prompters.

Wu-Decimal enables convenient, arbitrary-precision decimal arithmetic through a reader macro, #$, and an update to the pprint dispatch table. Wu-Decimal uses the CL rational type to store decimals, which enables numeric functions such as +, -, etc., to operate on decimal numbers in a natural way.

This is a native Common Lisp graphics math library with an emphasis on performance and correctness.
