Dissect is a small Common Lisp library for introspecting the call stack and active restarts.

CL-SXML implements Oleg Kiselyov’s SXML, an S-expression-based rendering of the XML Infoset.

Flexi-streams is an implementation of "virtual" bivalent streams that can be layered atop real binary or bivalent streams and that can be used to read and write character data in various single- or multi-octet encodings which can be changed on the fly. It also supplies in-memory binary streams which are similar to string streams.

Linedit is a readline-style library written in Common Lisp that provides customizable line-editing for Common Lisp programs.

The Bordeaux-FFT library provides a reasonably efficient implementation of the Fast Fourier Transform and its inverse for complex-valued inputs, in portable Common Lisp.

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

This package is a simple date and time library.

Napa-FFT3 provides Discrete Fourier Transform (DFT) routines, but also buildings blocks to express common operations that involve DFTs: filtering, convolutions, etc.

PP-TOML is a Common Lisp library for parsing strings in the TOML configuration file format. It implements only the 0.1.0 specification of TOML.

nontrivial-gray-streams is a compatibility system for Gray streams, which is an extension to Common Lisp that makes it possible to implement Common Lisp streams using generic functions.

A library for encoding text in various web-savvy encodings.

This package provides an extensible implementation of defclass that can accurately control the expansion according to the metaclass and automatically detect the suitable metaclass by analyzing the defclass form.

This Common Lisp library provides a simple FIFO implementation with no external dependencies.

This library converts the elements from GObject Introspection into Common Lisp-style definitions, based on cl-gobject-introspection.

This package provides an automatic generator for ASDF's .asd files.

string-pokemonize provides a function that alternates uppercase and lowercase characters for a given string.

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 an embedded template engine for Common Lisp.

This package provides supports for unicode normalization, RFC8264 and RFC7564.

NFiles is a Common Lisp library to help manage file persistence and loading, in particular user-centric files like configuration files. It boasts the following features:

• Dynamic and customizable path expansion.

• Extensible serialization and deserialization.

• Cached reads and writes. When a file object expands to the same path as another one, a read or write on it won’t do anything in case there was no change since last write.

• (Experimental!) On-the-fly PGP encryption.

• Profile support.

• On read error, existing files are backed up.

• On write error, no file is written to disk, the existing file is preserved.

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

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 library implements a basic promise datastructure, which is useful for dealing with asynchronous behaviours. Importantly, this library does not use any other libraries or frameworks, and instead leaves the execution and state transition of promise objects in your control, making it easy to integrate.

This package provides Common Lisp bindings for libev.
