This is a small OS portability library to retrieve and set file attributes not supported by the Common Lisp standard functions.

3bz is an implementation of Deflate decompression (RFC 1951) optionally with zlib (RFC 1950) or gzip (RFC 1952) wrappers, with support for reading from foreign pointers (for use with mmap and similar, etc), and from CL octet vectors and streams.

Fully auto-generated Common Lisp bindings to Raylib and Raygui.

This is a portability library that allows one to fully override the standard debugger provided by their Common Lisp system for situations where binding *debugger-hook* is not enough -- most notably, for break.

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

cl-change-case is a library to convert strings between camelCase, PascalCase, snake_case, param-case, CONSTANT_CASE and more.

This is a Common Lisp library for creating PNG images.

This system implements a general definitions introspection library. It gives you the ability to retrieve definitions or bindings associated with designators such as symbols, packages, and names in general. For instance, it allows you to retrieve all function, type, variable, method, etc. definitions of a symbol.

This library extends LOG4CL system in a few ways:

* It helps with configuration of multiple appenders and layouts. * Has a facility to catch context fields and to log them. * Has a macro to log unhandled errors. * Adds a layout to write messages as JSON, which is useful for production as makes easier to parse and process such logs. * Uses the appenders which are not disabled in case of some error which again, should be useful for production.

CL-random-forest is an implementation of Random Forest for multiclass classification and univariate regression written in Common Lisp. It also includes an implementation of Global Refinement of Random Forest.

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

This package provides Common Lisp support for reading the Terragen .TER format. The format specification can be found at https://planetside.co.uk/wiki/index.php?title=Terragen_.TER_Format

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.

Command-Line-Args provides a main macro (command) that wraps a defun form and creates a new function that parses the command line arguments. It has support for command-line options, positional, and variadic arguments. It also generates a basic help message. The interface is meant to be easy and non-intrusive.

This package provides a safer variant of READ secure against internbombing, excessive input and macro characters.

Vernacular is a build and module system for languages that compile to Common Lisp. It allows languages to compile to Lisp while remaining part of the Common Lisp ecosystem. Vernacular languages interoperate with Common Lisp and one another.

Vernacular handles locating files, compiling files into FASLs, tracking dependencies and rebuilding, and export and import between your new language, Lisp, and any other language Vernacular supports.

Vernacular builds on Overlord and is inspired by Racket.

CHRONICITY is Common Lisp natural language date and time parser inspired by Ruby's Chronic.

This package provides the getopt function to parse command-line options. The options are organized in valid options, other arguments and unknown arguments. Optional Lisp conditions for error situations are also defined.

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

Opticl is a Common Lisp library for representing, processing, loading, and saving 2-dimensional pixel-based images.

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 Common Lisp library providing a unified way to work with package locks across supported Common Lisp implementations.

PARSER-COMBINATORS is a library implementing monadic parser combinators in Common Lisp, similar in concept to Haskell Parsec system.

Stealth-mixin is a Common Lisp library for creating stealth mixin classes. These are classes that are dynamically mixed into other classes without the latter being aware of it.
