This is a system to help you easily and quickly deploy standalone common lisp applications as binaries. Specifically it is geared towards applications with foreign library dependencies that run some kind of GUI.

This lisp library handles physical quantities which consist of

• value / magnitude

• uncertainty / error

• unit

where the type of the value can be any subtype of real. For the uncertainty, both absolute and relative values are possible. Combinations of lisp symbols or strings are used to describe units. User defined units including abbreviations and prefixes are supported. Error propagation and unit checking is performed for all defined operations.

FSet is a functional set-theoretic collections library for Common Lisp. Functional means that all update operations return a new collection rather than modifying an existing one in place. Set-theoretic means that collections may be nested arbitrarily with no additional programmer effort; for instance, sets may contain sets, maps may be keyed by sets, etc.

This is a minimalistic parser of command line options. The main advantage of the library is the ability to concisely define command line options once and then use this definition for parsing and extraction of command line arguments, as well as printing description of command line options (you get --help for free). This way you don't need to repeat yourself. Also, unix-opts doesn't depend on anything and precisely controls the behavior of the parser via Common Lisp restarts.

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 package provides a Common Lisp library for fetching and parsing RSS feeds data via HTTP. Currently, it supports RSS versions 0.90, 0.91, and 0.92 as well as RSS version 2.

One of the many things that didn't quite get into the Common Lisp standard was how to get a Lisp to output its call stack when something has gone wrong. As such, each Lisp has developed its own notion of what to display, how to display it, and what sort of arguments can be used to customize it. trivial-backtrace is a simple solution to generating a backtrace portably.

This system implements binding threading macros -- a kind of threading macros with different semantics than classical, Clojure core threading macros or their extension, swiss-arrows. Two Common Lisp implementations of those are arrows and arrow-macros.

This system is a fork of arrows with changes in semantics that make it impossible to merge back upstream.

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

MGL-GPR is a library of evolutionary algorithms such as Genetic Programming (evolving typed expressions from a set of operators and constants) and Differential Evolution.

This package is a geospatial library, based on cl-wkb, that implements the OGC Well-Known Binary geographic geometry data model with PostGIS 3d, 4d extensions, and provides WKB and EWKB encoding and decoding functionality.

UBIQUITOUS is a very easy-to-use library for persistent configuration storage. It automatically takes care of finding a suitable place to save your data, and provides simple functions to access and modify the data within.

definitions-systems provides a simple unified extensible way of processing named definitions.

Alternative to the compiler-macro library:

• Here, we do not treat compiler notes as warnings, but instead these are a separate class of conditions. These are also not errors.

• Two main condition classes are provided: compiler-macro-notes:note and compiler-macro-notes:optimization-failure-note. While the latter is a subclass of the former, the latter notes are printed in a slightly different manner to the former.

• To be able to correctly print the expansion path that led to the condition, user code is expected to avoid performing a nonlocal exit to a place outside with-notes.

Small library aiming to cut down time spent moving data between CLOS and JSON objects. It depends on YASON and it should be possible to use it alongside straight calls to functions from YASON.

This library implements various functions to access status information about the machine, process, etc.

3bz is an implementation of Deflate decompression (RFC 1951) optionally with zlib (RFC 1950) or gzip (RFC 1952) wrappers, with support for reading from foreign pointers (for use with mmap and similar, etc), and from CL octet vectors and streams.

Random-Sample is a library for reliably taking a random sample from a sequence.

This package provides Common Lisp math and statistics routines.

Hunchenissr works together with issr.js for the development of interactive (changing without page refreshes) websites making use of websocket and Common Lisp server HTML generation instead of mountains of convoluted Javascript.

Trivial-Benchmark runs a block of code many times and outputs some statistical data for it. On SBCL this includes the data from time, for all other implementations just the real-time and run-time data. However, you can extend the system by adding your own metrics to it, or even by adding additional statistical computeations.

BORDEAUX-THREADS is a proposed standard for a minimal MP/Threading interface. It is similar to the CLIM-SYS threading and lock support.

This package provides a stream based JSON parser/writer, well suited as building block for higher level libraries.
