Common Lisp port of Universal Tween Engine.

cl-json provides an encoder of Lisp objects to JSON format and a corresponding decoder of JSON data to Lisp objects. Both the encoder and the decoder are highly customizable; at the same time, the default settings ensure a very simple mode of operation, similar to that provided by yason or st-json.

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.

atomichron is a Common Lisp library which implements a time meter which tracks how many times a form is evaluated, and how long evaluation takes. It uses atomic instructions so that meters will present correct results in the presence of multiple threads, while trying to minimize synchronization latency.

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 is a Common Lisp library to extract EXIF information from image files.

This package provides a JSON-RPC 2.0 server/client for Common Lisp.

Random-Sample is a library for reliably taking a random sample from a sequence.

This package provides a grab bag of miscellaneous Common Lisp utilities.

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

Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.

This package provides a Language Server Protocol implementation for use with the Alive Visual Studio Code extension.

It can be used in Emacs like this:

(require 'lsp)
(defun lsp-lisp-alive-start-ls ()
 "Start the alive-lsp."
 (interactive)
 (when-let (((lsp--port-available "localhost" lsp-lisp-alive-port)))
  (lsp-async-start-process #'ignore #'ignore
   "sbcl"
   "--eval"
   "(require :asdf)"
   "--eval"
   "(asdf:load-system :alive-lsp)"
   "--eval"
   (format "(alive/server::start :port %s)"
    lsp-lisp-alive-port))))

Lack is a Common Lisp library which allows web applications to be constructed of modular components. It was originally a part of Clack, however it's going to be rewritten as an individual project since Clack v2 with performance and simplicity in mind.

This library simplifies functional programming in Common Lisp by making it easier to make new data structures with specified changes in place.

LTK is a Common Lisp binding for the Tk graphics toolkit. It is written in pure Common Lisp and does not require any Tk knowledge for its usage.

This is a Common Lisp library to make histograms using UTF-8 block characters.

This Common Lisp library focuses on the small set of basic color manipulations (lightening, compliments, etc.) you might use to generate a color palette for a GUI or web page.

This package provides a library to open a web browser to a URL.

This library provides almost the same code as used inside Quicklisp for drawning progress bars

File-Notify is a Common Lisp library for getting notifications for file accesses and changes.

Flexi-streams is an implementation of "virtual" bivalent streams that can be layered atop real binary or bivalent streams and that can be used to read and write character data in various single- or multi-octet encodings which can be changed on the fly. It also supplies in-memory binary streams which are similar to string streams.

This package provides a flexible shallow/deep copy mechanism for Common Lisp.

CL-FTP is a library which provides FTP client functionality to a Common Lisp program. CL-FTP uses the USOCKET package for network sockets and the SPLIT-SEQUENCE package for some parsing needs.

SB-CGA is a computer graphics algebra library for Common Lisp.

Despite the prefix it is actually portable - but optimizations that make it fast (using SIMD instructions) are currently implemented for SBCL/x86-64 only.
