simple-matrix is a Common Lisp library implementing some functions to work with matrices.

Typo is a portable library for Common Lisp that does approximate reasoning about types, but without consing.

This software provides an interface by which Common Lisp programs can access lexicographic data from WordNet.

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.

FLOW is a flowchart graph library. Unlike other graphing libraries, this one focuses on nodes in a graph having distinct ports through which connections to other nodes are formed. This helps in many concrete scenarios where it is important to distinguish not only which nodes are connected, but also how they are connected to each other.

Particularly, a lot of data flow and exchange problems can be reduced to such a flowchart. For example, an audio processing library may present its pipeline as a flowchart of segments that communicate with each other through audio sample buffers. Flow gives a convenient view onto this kind of problem, and even allows the generic visualisation of graphs in this format.

This Common Lisp library provides function to make QR codes and to save them as PNG files.

repl-utilities is a set of utilities which ease life at the REPL.

This library is a collection of utilities for writing compiler macros. It is intended to make it possible to make compiler macros much more useful, by granting them access to lexical type information, making the protocol for declining expansion more convenient, and establishing some information for signaling optimization advice to programmers. Some utilities to support this, especially for reasoning on types, are also included.

Cl-async is a library for general purpose, non-blocking programming in Common Lisp. It uses the libuv library as backend.

Simple library to create temporary directories.

Anaphora is the anaphoric macro collection from Hell: it includes many new fiends in addition to old friends like aif and awhen.

This library provides an asynchronous process execution mechanism for Common Lisp.

s-sysdeps is an abstraction layer over platform dependent functionality. This simple package is used as a building block in a number of other projects.

s-sysdeps abstracts:

• managing processes,

• implementing a standard TCP/IP server,

• opening a client TCP/IP socket stream,

• working with process locks.

This library provides the FORMGREP function and related utilities which find top-level Lisp forms matching the regular expression corresponding to an operator name, returning the matched forms and the names of the files and the line numbers where they were found.

This package provides matrix algebra functions for Common Lisp.

This Common Lisp library provides functions for Zstandard compression/decompression using bindings to the libzstd C library.

This is a dead-simple, non validating, inline CSS generator for Common Lisp. Its goals are axiomatic syntax, simple implementation to support portability, and boilerplate reduction in CSS.

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.

Aims to be fast, modular, cachable and concise. It does so by defining each tag as a macro which expands to code printing the respective HTML source. Also employs a DSL for element attributes.

This Common Lisp library provides a fast reader for data in LibSVM format.

NASDF is an ASDF extension providing utilities to ease system setup, testing and installation.

• Simple way to fetch Git submodules and “do the right thing” for setup. This may effectively supersede Quicklisp. A benefit of using Git submodules over the default Quicklisp distribution is improved reproducibility.

• Test helpers, like distinction between offline and online tests, or continuous integration options, and warning reports.

• Installation helpers, for instance to install libraries, icons and desktop files to the right directories.

This package provides a Common Lisp system with a collection of common tests and operations to help handling pathnames. It does not actually deal in handling the accessing of files on the underlying system however.

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

ALEXA is a tool similar to lex or flex for generating lexical analyzers. Unlike tools like lex, however, ALEXA defines a domain-specific language within your Lisp program, so you don't need to invoke a separate tool.
