NASDF is an ASDF extension providing utilities to ease system setup, testing and installation.

• Simple way to fetch Git submodules and “do the right thing” for setup. This may effectively supersede Quicklisp. A benefit of using Git submodules over the default Quicklisp distribution is improved reproducibility.

• Test helpers, like distinction between offline and online tests, or continuous integration options, and warning reports.

• Installation helpers, for instance to install libraries, icons and desktop files to the right directories.

Cluster is an assembler (initially for x86 and x86-64) with a difference. To avoid the issue of defining a syntax, the input to Cluster is a list of standard objects (i.e., instances of the class STANDARD-OBJECT), as opposed to a character file or S-expressions.

This collection of utilities is useful in contexts where you want a macro that uses lambda-lists in some fashion but need more precise processing.

Periods is a Common Lisp library providing a set of utilities for manipulating times, distances between times, and both contiguous and discontiguous ranges of time.

This is a reverse proxy server written in and configurable in Common Lisp. It supports WebSocket, HTTP, HTTPS, HTTP to HTTPS redirecting, port and host forwarding configuration using a real programming language, HTTP header and body manipulation (also using a real programming language).

This is a small library to help you with managing the Common Lisp docstrings for your library.

Library to fuzzily parse time and date strings into a universal-time timestamp.

This package provides some condition classes, functions and macros which may be useful when building slightly complex systems.

EXTERNAL-PROGRAM enables running programs outside the Lisp process. It is an attempt to make the RUN-PROGRAM functionality in implementations like SBCL and CCL as portable as possible without sacrificing much in the way of power.

cl-amb provides an implementation of John McCarthy's ambiguous operator in portable Common Lisp.

Inquisitor is a cross-implementation library providing encoding/end-of-line detection and external-format abstraction for Common Lisp.

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.

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 provides a Common Lisp wrapper system for the SDL 2.0 C Library.

This package provides a SDL2 based vector graphic library for Common Lisp.

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.

This is a Common Lisp library providing various utilities.

This package provides a Common Lisp implementation of ActivityPub and ActivityStreams standards for social networking.

Features:

• Parsing and un-parsing ActivityStreams JSON-LD objects to/from CLOS objects with convenient accessors on those.

• Sending and fetching ActivityStreams objects to/from the ActivityStreams-enabled HTTP(S) URLs.

• Semantic info extraction with methods like name*, url*, author*, and published*.

• No reliance on JSON parser. njson is used for parser-independent JSON handling. Load the parser backend you prefer!

This package provides an implementation of a base 16 builder for Common Lisp.

This package provides functions to encode or decode byte vectors or byte streams using the Z85 format, which is a base-85 encoding used by ZeroMQ.

Trucler defines a CLOS-based protocol to be used by Common Lisp compilers for environment query and update. In addition, library authors can use the trucler-native interface to inspect native environments. Trucler supports introspection for variables, functions, tags, blocks and optimization policies.

This package provides an ASN.1 encoder/decoder for Common Lisp.

This is a standalone promise implementation for Common Lisp. It is the successor to the now-deprecated cl-async-future project.

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