A heap-based priority queue whose first and foremost priority is speed.

This is a Common Lisp library to read and write disk-based file archives such as those generated by the tar and cpio programs on Unix.

3D-VECTORS is a library for vector math in 3D space. It contains most of the vector operations one would usually expect out of such a library and offers them both in non-modifying and modifying versions where applicable.

HTML parser/emitter for CommonDoc.

Pileup is a portable, performant, and thread-safe binary heap for Common Lisp.

DAEMON provides the functionality of daemonizing Common Lisp processes on UNIX like platforms.

This package provides support routines for the claw Common Lisp package.

Simplified-Types is a library that provides functions for simplifying Common Lisp type specifiers. The API consists of two functions:

• simplify-type takes a type specifier and, optionally, an environment, and returns the corresponding simplified type.

• simplified-type-of takes an object and returns the simplified type of that object.

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

This is a library to allow easy handling of external processes, and primarily to get their output. It handles proper copying of the standard and error outputs of the process simultaneously, both in a sequential and parallel fashion. It also features a lazy directory switching mechanism, to avoid running into parallelism problems when having to change directory.

Transducers are an ergonomic and extremely memory-efficient way to process a data source. Data source refers to simple collections like lists or vectors, but also potentially large files or generators of infinite data.

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.

GENERIC-COMPARABILITY is an implementation of CDR-8 (Generic Equality and Comparison for Common Lisp). CDR-8 provides an interface for the EQUALS function, which is defined as a general equality predicate, as well as a set of ordering (COMPARE) functions for comparison. The semantics are described in the CDR-8 standard.

cl-css-lite is a library for generating CSS from an s-exp based syntax. When compiled with Parenscript loaded in the Lisp image, it also provides the same CSS generation facilities in Parenscript-generated JavaScript code.

Alexandria is a collection of portable utilities. It does not contain conceptual extensions to Common Lisp. It is conservative in scope, and portable between implementations.

repl-utilities is a set of utilities which ease life at the REPL. It includes three sorts of features: introspective procedures, miscellaneous utility functions, and, pulling them together, methods to conveniently keep these symbols and optionally additional symbols available in whichever package you switch to.

GARBAGE-POOLS is Common Lisp re-implementation of the APR Pools for resource management.

Often times we need to destructure a form definition in a Common Lisp macro. This library provides a set of simple utilities to help with that.

Chemboy is a Common Lisp program for doing basic chemistry calculations. This package provides the text-based interface for Chemboy.

Named readtables is a library that creates a namespace for named readtables, which is akin to package namespacing in Common Lisp.

Fast-io is about improving performance to octet-vectors and octet streams (though primarily the former, while wrapping the latter).

cl-gopher is a Common Lisp library for interacting with the Gopher protocol.

It is suitable for building both clients and servers, and provides a sample client.

This library contains generic hacks meant to be used in any project. It was originally developed for the Cells library.

This package provides a hierarchy of major functions and auxiliary functions related to the structured analysis and processing of open text.
