This package provides a portability layer for the extensible sequences standard extension to Common Lisp. Extensible sequences allow you to create your own sequence types that integrate with the rest of the functions and operations that interact with sequences.

cl-all is a library and script for evaluating Common Lisp expressions in multiple implementations.

MAP-BIND is a macro that allows visual grouping of variables with their corresponding values in calls to mapping operators when using an inline LAMBDA.

This package contains an implementation of RFC 2388, which is used to process form data posted with HTTP POST method using enctype "multipart/form-data".

The py-configparser package implements the ConfigParser Python module functionality in Common Lisp. In short, it implements reading and writing of .INI-file style configuration files with sections containing key/value pairs of configuration options. In line with the functionalities in the python module, does this package implement basic interpolation of option values in other options.

This Common Lisp library provides a series data structure much like a sequence, with similar kinds of operations. The difference is that in many situations, operations on series may be composed functionally and yet execute iteratively, without the need to construct intermediate series values explicitly. In this manner, series provide both the clarity of a functional programming style and the efficiency of an iterative programming style.

Various ASDF extensions such as attached test and documentation system, explicit development support, etc.

This is a Common Lisp library to handle the IBM PC version of the IXF (Integration Exchange Format) file format.

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

A dataflow extension to Common Lisp that maintains a consistent state of cells according to functions specifying their relation.

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).

This is a Common Lisp bindings library to libfond, a simple OpenGL text rendering engine.

This package provides a pure-lisp implementation of a DNS client. It can be used to resolve hostnames, reverse-lookup IP addresses, and fetch other kinds of DNS records.

BOOST-JSON is a simple JSON parsing library for Common Lisp.

cl-smug is a library for parsing text, based on monadic parser combinators. Using a simple technique from the functional programming camp, cl-smug makes it simple to create quick extensible recursive descent parsers without funky syntax or impenetrable macrology.

This is a portability library that allows one to fully override the standard debugger provided by their Common Lisp system for situations where binding *debugger-hook* is not enough -- most notably, for break.

Provides a simple way of directing output to a stream according to the concise and intuitive semantics of FORMAT's stream argument.

This package provides matrix algebra functions for Common Lisp.

binascii is a Common Lisp library for converting binary data to ASCII text of some kind. Such conversions are common in email protocols (for encoding attachments to support old non-8-bit clean transports) or encoding binary data in HTTP and XML applications. binascii supports the encodings described in RFC 4648: base64, base32, base16, and variants. It also supports base85, used in Adobe's PostScript and PDF document formats, and a variant called ascii85, used by git for binary diff files.

Birch is a simple Common Lisp IRC client library. It makes use of CLOS for event handling.

This library can be used to display a progress bar on one line.

This is a baseline JPEG codec written in Common Lisp. It can be used for reading and writing JPEG image files.

This library extends LOG4CL system in a few ways:

* It helps with configuration of multiple appenders and layouts. * Has a facility to catch context fields and to log them. * Has a macro to log unhandled errors. * Adds a layout to write messages as JSON, which is useful for production as makes easier to parse and process such logs. * Uses the appenders which are not disabled in case of some error which again, should be useful for production.

This is a very simple implementation of SHA1 and HMAC-SHA1 for Common Lisp. The code is intended to be easy to follow and is therefore a little slower than it could be.
