Stealth-mixin is a Common Lisp library for creating stealth mixin classes. These are classes that are dynamically mixed into other classes without the latter being aware of it.

This is a Common Lisp library that implements the 9p network filesystem protocol.

This library provides modern file handling for Common Lisp, which avoids many of the pitfalls of pathnames.

This package provides a Common Lisp templating system based on Python Django with a syntax similar to Python Jinja2.

This is a Common Lisp library providing a set of macros for generating lexical analyzers automatically. The lexers generated using cl-lex can be used with cl-yacc.

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.

lparallel is a library for parallel programming in Common Lisp, featuring:

• a simple model of task submission with receiving queue,

• constructs for expressing fine-grained parallelism,

• asynchronous condition handling across thread boundaries,

• parallel versions of map, reduce, sort, remove, and many others,

• promises, futures, and delayed evaluation constructs,

• computation trees for parallelizing interconnected tasks,

• bounded and unbounded FIFO queues,

• high and low priority tasks,

• task killing by category,

• integrated timeouts.

Filtered functions provide an extension of CLOS generic function invocation that add a simple preprocessing step before the actual method dispatch is performed and thus enable the use of arbitrary predicates for selecting and applying methods. See http://www.p-cos.net/documents/filtered-dispatch.pdf for a paper that introduces and explains filtered functions in detail.

Salza2 is a Common Lisp library for creating compressed data in the zlib, deflate, or gzip data formats, described in RFC 1950, RFC 1951, and RFC 1952, respectively.

This library contains a lexer for syntaxes that use shell-like rules for quoting and commenting. It is a port of the shlex module from Python’s standard library.

This package provides an interface to the gnuplot plotting utility. The intention of the API is to resemble to some of the plot commands of octave or matlab.

This package provides a common lisp CFFI wrapper for the SciPy version of Cephes special functions.

This package provides a Common Lisp parser for glTF file format.

This is a simple extension to MODULARIZE that allows modules to define and trigger hooks, which other modules can hook on to.

This library provides all of

• ad hoc polymorphism and

• subtype polymorphism

• parametric polymorphism (in a very limited sense)

to dispatch on the basis of types rather than classes.

TRIVIAL-OCTET-STREAMS is a Common Lisp library implementing in-memory octet streams analogous to string streams.

TRIVIAL-TYPES provides missing but important type definitions such as PROPER-LIST, ASSOCIATION-LIST, PROPERTY-LIST and TUPLE.

This package provides an implementation of a base 16 builder for Common Lisp.

Support library for numcl that provides Julia-like runtime parametric type correctness in Common Lisp. It is based on CLtL2 extensions.

deeds allows for efficient event delivery to multiple handlers with a complex event filtering system.

This a Common Lisp library for reading and writing binary data. It is based on code from chapter 24 of the book Practical Common Lisp.

Simple scheme to classify file types in a hierarchical fashion.

This is a lightweight, non-consing, optimized queue implementation for Common Lisp.

Dexador is yet another HTTP client for Common Lisp with neat APIs and connection-pooling. It is meant to supersede Drakma.
