Simple color library for Common Lisp.

Envy is a configuration manager for various applications. Envy uses an environment variable to determine a configuration to use. This can separate configuration system from an implementation.

A miniature toolkit that contains some useful shifting/popping/pushing functions for arrays and vectors. Originally from Plump.

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 is a Common Lisp library to load images in the PNG image format, both from files on disk, or streams in memory.

This package provides a BNF parser in Common Lisp.

RUTILS is a syntactic utilities package for Common Lisp.

This package provides a small utility library to open a thing (usually a file or URL) in an appropriate handler (usually an external file manager or browser).

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.

This package provides a macro commonly used in livecoding to enable continuing when errors are raised. Simply wrap around a chunk of code and it provides a restart called continue which ignores the error and carrys on from the end of the body.

exit-hooks provides a portable way to automatically call some user-defined function when exiting Common Lisp (both quit from the REPL or a kill in a shell). Like atexit in C and Python or Java’s Runtime.addShutdownHook(). It currently supports SBCL, CCL, ECL, ABCL, Allegro CL, clisp and CMUCL. Before exit-hooks, there was no portable way of doing so and no staightforward way to use an exit hook on ABCL. It can be used for tasks like parmenantly save something when exiting Lisp.

This is a general Freetype 2 wrapper for Common Lisp using CFFI. It's geared toward both using Freetype directly by providing a simplified API, as well as providing access to the underlying C structures and functions for use with other libraries which may also use Freetype.

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.

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.

Periods is a Common Lisp library providing a set of utilities for manipulating times, distances between times, and both contiguous and discontiguous ranges of time.

Cl-tga was written to facilitate loading .tga files into OpenGL programs. It's a very simple library, and, at the moment, only supports non-RLE encoded forms of the files.

This Common Lisp library converts strings, symbols and keywords between any of the following typographical cases: PascalCase, camelCase, snake_case, kebab-case (lisp-case).

UFFI provides a universal foreign function interface (FFI) for Common Lisp.

cl-all is a library and script for evaluating Common Lisp expressions in multiple implementations.

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

Nodgui (No Drama GUI) is a Common Lisp binding for the Tk GUI toolkit. It also provides a few additional widgets more than the standard Tk ones.

simple-routes is a simple Common Lisp RESTful routing facility on top of Hunchentoot.

This is a Common Lisp library to change the capitalization and spacing of a string or a symbol. It can convert to and from Lisp, english, underscore and camel-case rules.

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.
