This Common Lisp library implements a parser generator for the ABNF grammar format as described in RFC2234. The generated parser is a regular expression scanner provided by the cl-ppcre lib, which means that we can't parse recursive grammar definition. One such definition is the ABNF definition as given by the RFC. Fortunately, as you have this lib, you most probably don't need to generate another parser to handle that particular ABNF grammar.

This package provides a Common Lisp wrapper system for the SDL 2.0 C Library.

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

Markup allows the use of HTML syntax with in Common Lisp code. This has the advantage of being able to copy HTML snippets and have them instantly be functional, less double quotes than a s-expression approach, and designers will be able to understand the embedded HTML.

This is a Common Lisp library providing lambda shorthand macros aiming to be used in cases where the word lambda and the arguments are longer than the body of the lambda.

This is a pure Common Lisp library to create, transform and render anti-aliased vectorial paths.

This package defines a Common Lisp package, :elements, with an ELEMENT structure and a number of functions to search the periodic table.

cl-css-lite is a library for generating CSS from an s-exp based syntax. When compiled with Parenscript loaded in the Lisp image, it also provides the same CSS generation facilities in Parenscript-generated JavaScript code.

The 3D-Spaces library implements a number of spatial query data structures; structures that can answer spatial range queries for optimized lookup, particularly suited for games.

This is a library for representing and mapping colours between their various spaces.

This package makes it possible to name classes by lists of symbols instead of symbols.

This package provides a Common Lisp library for defining OpenGL shader programs. There are also functions for referencing shader programs by name, querying for basic information about them, modifying uniform variables throughout the lifecycle of an OpenGL application, and managing certain OpenGL buffer object types (UBO, SSBO currently).

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.

NDebug provides a small set of utilities to make graphical (or, rather non-REPL-resident) Common Lisp applications easier to integrate with the standard Lisp debugger (*debugger-hook*, namely) and implementation-specific debugger hooks (via trivial-custom-debugger), especially in a multi-threaded context.

Forge is a generic build system. Refer to documentation for the specific kind of project you're building to get the full picture.

CLACHE provides a general caching facility for Common Lisp. The API is similar to the standard hash-table interface.

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.

This library tries to provide a way to detect what kind of type the given predicate is trying to check. This is different from inferring the return type of a function.

This package provides a generic cache management facility with configurable and extensible cache replacement policies. The actual cached data can be stored anywhere, with cacle taking charge of keeping track of which entry is to be discarded next when more space is needed for a new entry.

cl-syslog is a Common Lisp library that provides access to the syslog logging facility.

Plump is a parser for HTML/XML-like documents, focusing on being lenient towards invalid markup. It can handle things like invalid attributes, bad closing tag order, unencoded entities, inexistent tag types, self-closing tags and so on. It parses documents to a class representation and offers a small set of DOM functions to manipulate it. It can be extended to parse to your own classes.

This library introduces fast generic functions, i.e. functions that behave just like regular generic functions, except that the can be sealed on certain domains. If the compiler can then statically detect that the arguments to a fast generic function fall within such a domain, it will perform a variety of optimizations.

cl-inotify uses cl-cffi to provide a Common Lisp interface to the Linux inotify API.

This is a Common Lisp Markdown to HTML converter, using esrap for parsing, and grammar based on peg-markdown.
