MAGICFFI is a Common Lisp CFFI interface to libmagic(3), the file type determination library using magic numbers.

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).

Croatoan provides high-level Common Lisp CLOS bindings for the ncurses terminal library.

Html-entities is a Common Lisp library that lets you encode and decode entities in HTML.

ASDF-FLV provides support for file-local variables through ASDF. A file-local variable behaves like *PACKAGE* and *READTABLE* with respect to LOAD and COMPILE-FILE: a new dynamic binding is created before processing the file, so that any modification to the variable becomes essentially file-local.

In order to make one or several variables file-local, use the macros SET-FILE-LOCAL-VARIABLE(S).

The NUMPY-FILE-FORMAT library is a Common Lisp library for reading and writing NumPy .npy and .npz files.

cl-strings is a small, portable, dependency-free set of utilities that make it even easier to manipulate text in Common Lisp. It has 100% test coverage and works at least on sbcl, ecl, ccl, abcl and clisp.

This is a baseline JPEG codec written in Common Lisp. It can be used for reading and writing JPEG image files.

trivial-clipboard gives access to the system clipboard.

Unifies a parametrized type specifier against an actual type specifier. Importantly, it handles complicated array-subtypes and number-related types correctly.

Circular-Streams allows you to read streams circularly by wrapping real streams. Once you reach end-of-file of a stream, its file position will be reset to 0 and you're able to read it again.

This library features a rectangle packer for sprite and texture atlases.

Py4CL is a bridge between Common Lisp and Python, which enables Common Lisp to interact with Python code. It uses streams to communicate with a separate python process, the approach taken by cl4py. This is different to the CFFI approach used by burgled-batteries, but has the same goal.

CL-ALGEBRAIC-DATA-TYPE, or ADT, is a library for defining algebraic data types in a similar spirit to Haskell or Standard ML, as well as for operating on them.

Very basic library for dealing with CL's hash tables. The idea was spawned through working with enough JSON APIs and config files, causing a lot of headaches in the process.

This package contains an implementation of RFC 2388, which is used to process form data posted with HTTP POST method using enctype "multipart/form-data".

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

This package provides a shim between Python3 (specifically, the CPython implementation of Python) and Common Lisp.

This is a Common Lisp implementation for the Mustache template system. More details on the standard are available at https://mustache.github.io.

CLOBBER is an alternative to so-called object prevalence, and in particular to cl-prevalence. Clobber is both simpler, more flexible, and more robust than systems based on object prevalence.

This is a simple queue library for Common Lisp with features such as non-consing thread safe queues and fibonacci priority queues.

This package provides a simple yet powerful value inheritance scheme.

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

This package provides a portability layer for the extensible sequences standard extension to Common Lisp. Extensible sequences allow you to create your own sequence types that integrate with the rest of the functions and operations that interact with sequences.
