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

Scrape on-line documentation out of a running Lisp image.

Defstar is a collection of Common Lisp macros that can be used in place of defun, defmethod, defgeneric, defvar, defparameter, flet, labels, let* and lambda. Each macro has the same name as the form it replaces, with a star added at the end, e.g. defun. (the exception is the let* replacement, which is called *let).

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 package provides highly optimized base64 encoding and decoding. Besides conversion to and from strings, integer conversions are supported. Encoding with Uniform Resource Identifiers is supported by using a modified encoding table that uses only URI-compatible characters.

This library is a collection of functions and macros for manipulating Common Lisp arrays and performing numerical calculations with them.

The GTWIWTG library (Generators The Way I Want Them Generated -- technically not generators, but iterators) is meant to be small, explorable, and understandable.

Common Lisp port of Universal Tween Engine.

This package provides a macro that allows foreign functions to access the contents of the array at a given pointer, using the best available method given the Common Lisp implementation.

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 is an implementation of a Markdown parser in Common Lisp.

CL-PPCRE is a portable regular expression library for Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

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

This package provides Common Lisp system collecting tools written to wrangle OpenGL Shader Language (GLSL) source files.

CL-ANA is a data analysis library in Common Lisp providing tabular and binned data analysis along with nonlinear least squares fitting and visualization.

assoc-utils provides utilities for manipulating association lists in Common Lisp.

A Common Lisp library for generating a human-readable diff of two HTML documents.

Parseq (pronounced parsec) is a parsing library for common lisp. It can be used for parsing lisp's sequences types: strings, vectors (e.g. binary data) and lists. Furthermore, parseq is able to parse nested structures such as trees (e.g. lists of lists, lists of vectors, vectors of strings).

Parseq uses parsing expression grammars (PEG) that can be defined through a simple interface. Extensions to the standard parsing expressions are available. Parsing expressions can be parameterised and made context aware. Additionally, the definition of each parsing expression allows the arbitrary transformation of the parsing tree.

The library is inspired by Esrap and uses a very similar interface. No code is shared between the two projects, however. The features of Esrap are are mostly included in parseq and complemented with additional, orthogonal features. Any resemblance to esrap-liquid is merely coincidental.

BOOST-LEXER is a tokenizer for Common Lisp that makes heavy use of BOOST-RE.

This package is a list manipulation library for Common Lisp inspired by Haskell package Data.List.

One of the many things that didn't quite get into the Common Lisp standard was how to get a Lisp to output its call stack when something has gone wrong. As such, each Lisp has developed its own notion of what to display, how to display it, and what sort of arguments can be used to customize it. trivial-backtrace is a simple solution to generating a backtrace portably.

XSubseq provides functions to be able to handle "subseq"s more effieiently.

This package provides a compute-effective-slot-definition-initargs generic function that allows for more ergonomic initialization of effective slot definition objects.

cl-ansi-text provides utilities which enable printing to an ANSI terminal with colored text. It provides the macro with-color which causes everything printed in the body to be displayed with the provided color. It further provides functions which will print the argument with the named color.
