This package provides the Common Lisp HTTP server WOO, which is built on top of the libev event library.

This package provides a framework to unify arbitrary Common Lisp objects while constructing bindings for placeholders (unification variables) in a template sublanguage.

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.

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

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

THE-COST-OF-NOTHING is a library for measuring the run time of Common Lisp code. It provides macros and functions for accurate benchmarking and lightweight monitoring. Furthermore, it provides predefined benchmarks to determine the cost of certain actions on a given platform and implementation.

CL-PPCRE is a portable regular expression library for Common Lisp, which is compatible with perl. It is pretty fast, thread-safe, and compatible with ANSI-compliant Common Lisp implementations.

FXML is a secure-by-default, error-recovering XML parser and serializer. It is a fork of CXML.

You should use FXML instead of CXML if:

• You are parsing potentially ill-formed XML.

• You are parsing potentially malicious XML.

• You need to use Klacks with namespaces.

FXML’s API is very close to CXML's, and for the most part you can refer to the CXML documentation for usage.

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

parse-number is a library of functions for parsing strings into one of the standard Common Lisp number types without using the reader. parse-number accepts an arbitrary string and attempts to parse the string into one of the standard Common Lisp number types, if possible, or else parse-number signals an error of type invalid-number.

This library validates superclasses according to a simple substitution model, thereby greatly simplifying the definition of class mixins.

Loop has a consistent interface unlike other looping abstractions and ANSI list operations. You can define your own efters and gatherers that integrate tightly into other operations. All operations are non-consing when possible.

This package provides CFFI bindings to convert between different character encodings using iconv.

This is an extension library to pathname-utils, to allow dealing with common problems with filesystems, such as listing files, probing file types, determining default directories, etc.

This package provides the getopt function to parse command-line options. The options are organized in valid options, other arguments and unknown arguments. Optional Lisp conditions for error situations are also defined.

Command-Line-Args provides a main macro (command) that wraps a defun form and creates a new function that parses the command line arguments. It has support for command-line options, positional, and variadic arguments. It also generates a basic help message. The interface is meant to be easy and non-intrusive.

This is a small Common Lisp library that finds an open port within a range.

Overlord is a build system in Common Lisp. It is a real build system, with all the modern features: rules with multiple outputs, parallel builds, immunity to clock issues, and dynamic dependencies.

But Overlord is more than another build system. Overlord is a uniform approach to dependencies inside or outside of a Lisp image. Overlord is to Make what Lisp macros are to C macros.

Overlord is designed to be used from the Lisp REPL. A command line interface is available in a separate repository. See https://github.com/ruricolist/overlord-cli.

This library provides low-level libuv bindings for Common Lisp.

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.

Feeder is a syndication feed library. It presents a general protocol for representation of feed items, as well as a framework to translate these objects from and to external formats. It also implements the RSS 2.0 and Atom formats within this framework.

Ironclad is a cryptography library written entirely in Common Lisp. It includes support for several popular ciphers, digests, MACs and public key cryptography algorithms. For several implementations that support Gray streams, support is included for convenient stream wrappers.

cl-num-utils implements simple numerical functions for Common Lisp, including:

• num=, a comparison operator for floats

• simple arithmeric functions, like sum and l2norm

• elementwise operations for arrays

• intervals

• special matrices and shorthand for their input

• sample statistics

• Chebyshev polynomials

• univariate rootfinding

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.
