This is a very simple color library for Common Lisp, providing:

• Types for representing colors in HSV, HSL, and RGB spaces.

• Simple conversion functions between the above types.

• Function printing colors to HEX, RGB, RGBA, and HSL.

• Predefined colors from X11, SVG, and GDK.

This Common Lisp library provides functions for lzip (LZMA) compression/decompression using bindings to the lzlib C library.

Transducers are an ergonomic and extremely memory-efficient way to process a data source. Data source refers to simple collections like lists or vectors, but also potentially large files or generators of infinite data.

CL-FTP is a library which provides FTP client functionality to a Common Lisp program. CL-FTP uses the USOCKET package for network sockets and the SPLIT-SEQUENCE package for some parsing needs.

fast-http is a HTTP request/response protocol parser for Common Lisp.

generic-cl provides a generic function wrapper over various functions in the Common Lisp standard, such as equality predicates and sequence operations. The goal of this wrapper is to provide a standard interface to common operations, such as testing for the equality of two objects, which is extensible to user-defined types.

Alternative to the compiler-macro library:

• Here, we do not treat compiler notes as warnings, but instead these are a separate class of conditions. These are also not errors.

• Two main condition classes are provided: compiler-macro-notes:note and compiler-macro-notes:optimization-failure-note. While the latter is a subclass of the former, the latter notes are printed in a slightly different manner to the former.

• To be able to correctly print the expansion path that led to the condition, user code is expected to avoid performing a nonlocal exit to a place outside with-notes.

A JSON Object Signing and Encryption (JOSE) implementation for Common Lisp.

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.

LLA is a high-level Common Lisp library built on BLAS and LAPACK, but providing a much more abstract interface with the purpose of freeing the user from low-level concerns and reducing the number of bugs in numerical code.

This library allows you to define custom indentation hints for your macros if the one recognised by SLIME automatically produces unwanted results.

This Common Lisp library provides string encoding and decoding routines for IDNA, the International Domain Names in Applications.

This data structure can be used to store the history of visited paths or URLs with a file or web browser, in a way that no “forward” element is ever forgotten.

The history tree is “global” in the sense that multiple owners (e.g. tabs) can have overlapping histories. On top of that, an owner can spawn another one, starting from one of its nodes (typically when you open a URL in a new tab).

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

data-format-validation is a library for Common Lisp providing a consistent regular interface for converting (and validating) external data (in the form of strings usually) into internal data types and for formatting internal data back into external presentable strings, all according to a conversion or type specification.

THE-COST-OF-NOTHING is a library for measuring the run time of Common Lisp code. It provides macros and functions for accurate benchmarking and lightweight monitoring. Furthermore, it provides predefined benchmarks to determine the cost of certain actions on a given platform and implementation.

Supertrace provides a superior Common Lisp trace functionality for debugging and profiling real world applications.

Cluffer is a library for representing the buffer of a text editor. As such, it defines a set of CLOS protocols for client code to interact with the buffer contents in various ways, and it supplies different implementations of those protocols for different purposes.

Dynamic-mixins is for simple, dynamic class combination; it allows objects to be mixed and updated without manually defining many permutations.

This package provides a Common Lisp implementation of ActivityPub and ActivityStreams standards for social networking.

Features:

• Parsing and un-parsing ActivityStreams JSON-LD objects to/from CLOS objects with convenient accessors on those.

• Sending and fetching ActivityStreams objects to/from the ActivityStreams-enabled HTTP(S) URLs.

• Semantic info extraction with methods like name*, url*, author*, and published*.

• No reliance on JSON parser. njson is used for parser-independent JSON handling. Load the parser backend you prefer!

Anaphora is the anaphoric macro collection from Hell: it includes many new fiends in addition to old friends like aif and awhen.

cl-amb provides an implementation of John McCarthy's ambiguous operator in portable Common Lisp.

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.

Wayflan is a from-scratch Wayland communication library for Common Lisp. It makes a good-faith effort to mimic libwayland behavior not defined in the Wayland spec, to keep compatibility between the two libraries.

Wayflan is not a compositor nor a GUI toolkit. Its purpose is to parse Wayland protocol XML documents and exchange Wayland messages between other processes.

Features:

• Client support

• All implementation done in Common Lisp from the socket up

• Enum values are translated into keywords

• Wayland protocol introspection

• ASDF component :wayflan-client-impl generates code from XML. ASDF's extensible components make it possible to teach your program new protocols for Wayland without the need of a special build system.
