Zippy is a library for the PKWARE Zip archive format. It can read and write zip files. It features:

• archive inspection without extraction;

• Zip64 support;

• split archive support;

• PKWARE decryption;

• fast deflate decompression thanks to 3bz;

• operates on streams and vectors;

• can compress stream->stream;

• extensible for other encryption and compression mechanisms.

PARSER-COMBINATORS is a library implementing monadic parser combinators in Common Lisp, similar in concept to Haskell Parsec system.

postmodern is a Common Lisp library for interacting with PostgreSQL databases. It provides the following features:

• Efficient communication with the database server without need for foreign libraries.

• Support for UTF-8 on Unicode-aware Lisp implementations.

• A syntax for mixing SQL and Lisp code.

• Convenient support for prepared statements and stored procedures.

• A metaclass for simple database-access objects.

This package produces 4 systems: postmodern, cl-postgres, s-sql, simple-date

SIMPLE-DATE is a very basic implementation of date and time objects, used to support storing and retrieving time-related SQL types. It is not loaded by default and you can use local-time (which has support for timezones) instead.

S-SQL is used to compile s-expressions to strings of SQL code, escaping any Lisp values inside, and doing as much as possible of the work at compile time.

CL-POSTGRES is the low-level library used for interfacing with a PostgreSQL server over a socket.

POSTMODERN itself is a wrapper around these packages and provides higher level functions, a very simple data access object that can be mapped directly to database tables and some convenient utilities. It then tries to put all these things together into a convenient programming interface

This package provides a utility library intended at providing configurable reader macros for common tasks such as accessors, hash-tables, sets, uiop:run-program, arrays and a few others.

These common lisp sources contain two variants of the Nelder-Mead algorithm. The original algorithm and a provably convergent, reliable variant by A. Bürmen et al, called the GRNMA.

This package provides the LOCAL-TIME extensions for the cl-postgres ASDF system of postmodern.

simple-optimization is a Common Lisp library providing a function to solve unconstrained optimization problems numerically using either the gradient descent or a quasi-Newton method.

This package provides Common Lisp bindings to the pango text layout library.

This is a Common Lisp utilities library originating from the Zombie Raptor game engine project.

Generic documentation builder for Common Lisp projects.

This package provides GNU gettext completely implemented in Common Lisp without any C library bindings.

This library extracts the TLD (Top Level Domain) from domains. The information is taken from https://publicsuffix.org.

This is a Common Lisp package for hash table creation with flexible, extensible initializers.

This library is part of NUMCL. It provides a macro SPECIALIZED that performs a Julia-like dispatch on the arguments, lazily compiling a type-specific version of the function from the same code. The main target of this macro is speed.

Slite interactively runs your Common Lisp tests (currently only FiveAM and Parachute are supported). It allows you to see the summary of test failures, jump to test definitions, rerun tests with debugger all from inside Emacs.

In order to work, this also requires the slite Common Lisp system to be present. See the *cl-slite packages.

Opticl is a Common Lisp library for representing, processing, loading, and saving 2-dimensional pixel-based images.

This is a small library to display a native GUI message box. This can be useful to show error messages and other informational pieces should the application fail and be unable to do so using its standard UI.

CL-TYPESETTING is a cross-platform Common Lisp typesetting library for all kind of typesetting applications.

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

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

fast-websocket is an optimized low-level WebSocket protocol parser/composer.

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

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!

PARSE is a simple token parsing library for Common Lisp.
