CL-PUNCH is a Scala-like anonymous lambda literal.

cl-rucksack is a persistence library based on Arthur Lemmens' Rucksack with some enhancements.

This library contains a lexer for syntaxes that use shell-like rules for quoting and commenting. It is a port of the shlex module from Python’s standard library.

This package creates GraphViz DOT files from an equivalent s-expression representation.

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.

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.

This library is a collection of utilities for writing compiler macros. It is intended to make it possible to make compiler macros much more useful, by granting them access to lexical type information, making the protocol for declining expansion more convenient, and establishing some information for signaling optimization advice to programmers. Some utilities to support this, especially for reasoning on types, are also included.

Charje.documentation can used to parse Common Lisp docstrings the charje way, or it can be used to create custom docstring parsers. Docstring parsers are composed using mixin classes and initialization methods.

Serapeum is a conservative library of Common Lisp utilities. It is a supplement, not a competitor, to Alexandria.

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.

This is a Common Lisp library for solving linear programming problems.

CL-DATA-STRUCTURES is a Common Lisp library providing a portable collection of mutable and immutable data structures (dictionaries, sets, queues, sequences) and algorithms.

This is a Common Lisp wrapper for interacting with the Redis data structure store.

F2cl is a Common Lisp library that can convert Fortran 77 code into Common Lisp code.

This package provides a Common Lisp web framework for building GUI applications. CLOG can take the place, or work along side, most cross platform GUI frameworks and website frameworks. The CLOG package starts up the connectivity to the browser or other websocket client (often a browser embedded in a native template application).

Montezuma is a text search engine library for Lisp based on the Ferret library for Ruby, which is itself based on the Lucene library for Java.

Charje.documentation can used to parse Common Lisp docstrings the charje way, or it can be used to create custom docstring parsers. Docstring parsers are composed using mixin classes and initialization methods.

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

Radiance is a web application environment, which is sort of like a web framework, but more general, more flexible. It should let you write personal websites and generally deployable applications easily and in such a way that they can be used on practically any setup without having to undergo special adaptations.

This library provides functions for determining the value types of Common Lisp forms, based on type information contained in the environment.

In order for this library to work the values types of variables and return types of functions have to be declared.

Macros and symbol-macros are fully expanded and all special forms, except CATCH, are supported.

This is a Common Lisp library providing a set of macros for generating lexical analyzers automatically. The lexers generated using cl-lex can be used with cl-yacc.

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

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.

DATA-SIFT is a Common Lisp data validation and transformation library inspired by cl-data-format-validation and WTForms validators.
