This an implementation of CDR 2: generic hash tables for Common Lisp

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

This package provides Common Lisp bindings to GSSAPI, which is designed to provide a standard API to authentication services. The API itself is generic, and the system can provide different underlying implementations. The most common one is Kerberos, which has several implementations, the most common of which is probably Active Directory.

Use rich-formatter to format documentation with sections :syntax, :arguments, :examples, :description, :returns, :side-effects, :thread-safety, :affected-by, :see-also and :notes. Gather unformatted input by using rich-aggregating-formatter and *DOCUMENTATION* variable. Find gathered documentation with find-documentation function. Execute code stored in documentation with execute-documentation. See the examples in the src/documentation.lisp file. See the documentation-utils system for more information.

Cells is a mature, stable extension to CLOS allowing one to create classes whose instances can have slot values determined by instance-specific formulas.

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

Trial is a game engine written in Common Lisp. Unlike many other engines, it is meant to be more of a loose connection of components that can be fit together as required by any particular game.

Germinal is a server for the Gemini protocol, written in Common Lisp.

CF is a Common Lisp library for doing computations using continued fractions.

cl-mssql provides an interface to connect to Microsoft SQL server. It uses the libsybdb foreign library provided by the FreeTDS project.

RE is a small, portable, lightweight, and quick, regular expression library for Common Lisp. It is a non-recursive, backtracing VM.

DIFF is a package for computing various forms of differences between blobs of data and then doing neat things with those differences. Currently diff knows how to compute three common forms of differences: "unified" format diffs, "context" format diffs, and "vdelta" format binary diffs.

This is a Common Lisp Markdown to HTML converter, using esrap for parsing, and grammar based on peg-markdown.

This library provides a uniform API, as specified in Common Lisp the Language 2, for accessing information about variable and function bindings from implementation-defined lexical environment objects. All major Common Lisp implementations are supported, even those which don't support the CLTL2 environment access API.

Common Lisp port of Clojure's instaparse parser library - GLL parsing with EBNF/ABNF support.

This is a system presenting a protocol for "file systems": things that present a collection of "files," which are things that have several attributes, and a central data payload. Most notably this includes the OS filesystem, but can also be used to address other filesystem-like things like archives, object stores, etc. in the same manner.

This package provides an embedded template engine for Common Lisp.

This package allows flexible specification of package-local preferences.

ADOPT is a simple UNIX-style option parser in Common Lisp, heavily influenced by Python's optparse and argparse.

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

Bobbin is a simple word-wrapping library for strings in Common Lisp. It aims to be simple, work nicely for the majority of cases, and degrade gracefully for edge cases. It is not particularly concerned with speed — if you need very high-performance word wrapping, Bobbin is not for you.

This package provides a Common Lisp implementation of the semantic versioning specification: http://semver.org.

This package contains a few utility functions from the LispWorks library that are used in software such as ContextL.
