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.

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.

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.

Drakma is a full-featured HTTP client implemented in Common Lisp. It knows how to handle HTTP/1.1 chunking, persistent connections, re-usable sockets, SSL, continuable uploads, file uploads, cookies, and more.

This is a Gettext-style internationalisation framework for Common Lisp.

This is a client library to interact with the "mod.io" (https://mod.io) platform to manage "mods" or extensions for games and other applications. It covers the full v1 API and includes convenience methods to make interacting with the API as well as syncing mods and so on easy.

CL-INTERPOL is a library for Common Lisp which modifies the reader so that you can have interpolation within strings similar to Perl or Unix Shell scripts. It also provides various ways to insert arbitrary characters into literal strings even if your editor/IDE doesn't support them.

This package provides an embedded template engine for Common Lisp.

CL-octet-streams is a library implementing in-memory octet streams for Common Lisp. It was inspired by the trivial-octet-streams and cl-plumbing libraries.

This package provides CFFI bindings to the ASSIMP library for Common Lisp.

This is a portability library that allows one to fully override the standard debugger provided by their Common Lisp system for situations where binding *debugger-hook* is not enough -- most notably, for break.

cl-jpl-util is a collection of Common Lisp utility functions and macros, primarily for software projects written in CL by the author.

trivial-clipboard gives access to the system clipboard.

This library is part of NUMCL. It provides a macro SPECIALIZED that performs a Julia-like dispatch on the arguments, lazily compiling a type-specific version of the function from the same code. The main target of this macro is speed.

SLY is a fork of SLIME, an IDE backend for Common Lisp. It also features a completely redesigned REPL based on Emacs's own full-featured comint-mode, live code annotations, and a consistent interactive button interface. Everything can be copied to the REPL. One can create multiple inspectors with independent history.

Supertrace provides a superior Common Lisp trace functionality for debugging and profiling real world applications.

This is an interface to the git binary to make controlling it from within Common Lisp much easier. It might not ever reach full coverage of all features given git's immense size, but features will be added as they are needed. The low-level command API is fully mapped however.

This package allows flexible specification of package-local preferences.

This library is a portable socket interface that allows CL programs to open connected (client) stream sockets to network services.

cl-rmath is a simple, autogenerated foreign interface for the standalone R API libRmath. There has been no effort to provide a high-level interface for the original library, instead, this library is meant to serve as a building block for such an interface.

cl-strings is a small, portable, dependency-free set of utilities that make it even easier to manipulate text in Common Lisp. It has 100% test coverage and works at least on sbcl, ecl, ccl, abcl and clisp.

The 3d-math library implements types, operators, and algorithms commonly used in math for 2D and 3D graphics. It supersedes and combines the prior libraries 3d-vectors, 3d-matrices, 3d-quaternions, and 3d-transforms. The new API is largely but not entirely backwards compatible, and adds new functionality.

This library implements efficient algorithms that calculate various string metrics in Common Lisp:

• Damerau-Levenshtein distance

• Hamming distance

• Jaccard similarity coefficient

• Jaro distance

• Jaro-Winkler distance

• Levenshtein distance

• Normalized Damerau-Levenshtein distance

• Normalized Levenshtein distance

• Overlap coefficient

Clamp is an attempt to bring the powerful, but verbose, language of Common Lisp up to the terseness of Arc.

There are two parts to Clamp. There is the core of Clamp, which implements the utilities of Arc that are easily converted from Arc to Common Lisp. The other part is the "experimental" part. It contains features of Arc that are not so easy to copy (ssyntax, argument destructuring, etc.).
