Skippy is a Common Lisp library to read and write GIF image files.

cl-smug is a library for parsing text, based on monadic parser combinators. Using a simple technique from the functional programming camp, cl-smug makes it simple to create quick extensible recursive descent parsers without funky syntax or impenetrable macrology.

cl-tar-file is a Common Lisp library that allows reading from and writing to various tar archive formats. Currently supported are the POSIX ustar, PAX (ustar with a few new entry types), GNU, and v7 (very old) formats.

This library is rather low level and is focused exclusively on reading and writing physical tar file entries using streams. Therefore, it contains no functionality for automatically building archives from a set of files on the filesystem or writing the contents of a file to the filesystem. Additionally, there are no smarts that read multiple physical entries and combine them into a single logical entry (e.g., with PAX extended headers or GNU long link/path name support). For a higher-level library that reads and writes logical entries, and also includes filesystem integration, see cl-tar.

This is a YAML parser and emitter for Common Lisp built on top of libyaml.

KMRCL is a collection of utilities used by a number of Kevin Rosenberg's Common Lisp packages.

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

This package provides a Common Lisp system helping in scripting, it uses uiop:run-program as a backend.

This is a wrapper for the SDL2_TTF library used for loading fonts and creating text assets. The library, in it's current state, can load TTF and OTF fonts and render fonts with the three different rendering modes provided by the C library (solid, shaded, and blended). While Latin text, UTF8, UNICODE, and Glyph text rendering is available only Latin text has been tested (as shown in the examples).

cl-docutils is a Common Lisp implementation of the Docutils text processing system for processing plaintext into presentational formats such as HTML and LaTeX. It is based upon the Python Docutils reference implementation but uses Common Lisp idioms making it easier to extend and more flexible. As with the reference implementation it includes a parser for the reStructured text plaintext markup syntax which is suitable for marking up documentation and for use as user markup for collaborative web sites. It is successfully used to support a higher education peer-review assessment and online tutorial system.

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.

This Common Lisp library provides a series data structure much like a sequence, with similar kinds of operations. The difference is that in many situations, operations on series may be composed functionally and yet execute iteratively, without the need to construct intermediate series values explicitly. In this manner, series provide both the clarity of a functional programming style and the efficiency of an iterative programming style.

This Common Lisp library provides a tiny utility to change the size of a simple-array ensuring that the resulting array is still a simple-array.

This package provides a library to open a web browser to a URL.

High performance JSON encoder and decoder. Currently support: SBCL, CCL.

This package provides a hierarchy of major functions and auxiliary functions related to the structured analysis and processing of open text.

s-sysdeps is an abstraction layer over platform dependent functionality. This simple package is used as a building block in a number of other projects.

s-sysdeps abstracts:

• managing processes,

• implementing a standard TCP/IP server,

• opening a client TCP/IP socket stream,

• working with process locks.

These common lisp sources contain two variants of the Nelder-Mead algorithm. The original algorithm and a provably convergent, reliable variant by A. Bürmen et al, called the GRNMA.

This package provides a set of bindings and utilities for accessing the OpenGL (Mesa), GLU and GLUT (FreeGLUT) APIs using CFFI.

This library implements the let+ macro, which is a dectructuring extension of let*. It features:

• Clean, consistent syntax and small implementation (less than 300 LOC, not counting tests)

• Placeholder macros allow editor hints and syntax highlighting

• &ign for ignored values (in forms where that makes sense)

• Very easy to extend

Schemeish implements several useful Scheme constructs for Common Lisp. These include named-let, define, scheme argument lists, and a shortcut to FUNCALL with [] instead of ().

This is a native Common Lisp graphics math library with an emphasis on performance and correctness.

cl-alexandria-plus is a conservative set of extensions to cl-alexandria utilities.

This library allows for cooperative multitasking with help of cl-cont for continuations. It tries to mimic the API of bordeaux-threads as much as possible.

Dynamic-Classes helps to ease the prototyping process by bringing dynamism to class definition.
