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

This is a coroutine library for Common Lisp implemented using the continuations of the cl-cont library.

Converts Markdown text into CommonDoc nodes and vice versa.

This library simplifies functional programming in Common Lisp by making it easier to make new data structures with specified changes in place.

The Bordeaux-FFT library provides a reasonably efficient implementation of the Fast Fourier Transform and its inverse for complex-valued inputs, in portable Common Lisp.

It can sometimes be useful to be able to parse chemical compounds in a user-friendly syntax into easy-to-manipulate s-expressions. You also want to be able to go in reverse. You could probably write your own parser — or you could just install the chemical-compounds package.

This is a utility kit for functionality related to OpenGL. It provides the following:

• kit.glm: This re-exports sb-cga and mathkit for convenience.

• kit.gl.shader: This provides shader dictionary and compilation functionality similar to what was originally found in sdl2kit.

• kit.gl.vao: This provides an interface for Vertex Array Objects.

This library allows you to open native file dialogs to open and save files. This is useful if you have an application that's primarily text based and would like a more convenient file selection utility, or if you are working with a UI toolkit that does not offer a way to access the native file dialogs directly.

S-XML is a simple XML parser implemented in Common Lisp. This XML parser implementation has the following features:

• It works (handling many common XML usages).

• It is very small (the core is about 700 lines of code, including comments and whitespace).

• It has a core API that is simple, efficient and pure functional, much like that from SSAX (see also http://ssax.sourceforge.net).

• It supports different DOM models: an XSML-based one, an LXML-based one and a classic xml-element struct based one.

• It is reasonably time and space efficient (internally avoiding garbage generatation as much as possible).

• It does support CDATA.

• It should support the same character sets as your Common Lisp implementation.

• It does support XML name spaces.

This XML parser implementation has the following limitations:

• It does not support any special tags (like processing instructions).

• It is not validating, even skips DTD's all together.

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

This is a Common Lisp library to read and write disk-based file archives such as those generated by the tar and cpio programs on Unix.

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.

BOOST-PARSE is a simple token parsing library for Common Lisp.

bt-semaphore is a semaphore implementation for use with bordeaux-threads.

simple-neural-network is a Common Lisp library for creating, training and using basic neural networks. The networks created by this library are feedforward neural networks trained using backpropagation.

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.

This package provides a stream based JSON parser/writer, well suited as building block for higher level libraries.

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

cl-charms is an interface to libcurses in Common Lisp. It provides both a raw, low-level interface to libcurses via CFFI, and a more higher-level lispier interface.

The Readline library provides a set of functions for use by applications that allow users to edit command lines as they are typed in. Both Emacs and vi editing modes are available. The Readline library includes additional functions to maintain a list of previously-entered command lines, to recall and perhaps reedit those lines, and perform csh-like history expansion on previous commands.

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.

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 trivial line-input library for VT-like terminals.

CL-UNICODE is a portable Unicode library Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.
