This prompter library is heavily inspired by Emacs' minibuffer and Helm (https://emacs-helm.github.io/helm/). It only deals with the backend side of things, it does not handle any display. Features include asynchronous suggestion computation, multiple sources, actions and resumable prompters.

This is a packrat parser for Common Lisp. In addition to regular Packrat / Parsing Grammar / TDPL features ESRAP supports:

• dynamic redefinition of nonterminals

• inline grammars

• semantic predicates

• introspective facilities (describing grammars, tracing, setting breaks)

• left-recursive grammars

• functions as terminals

• accurate, customizable parse error reports

This package provides a JSON Pointer (RFC6901) implementation for Common Lisp. This library aims to be independent from any JSON libraries (as much as possible).

Nodgui (No Drama GUI) is a Common Lisp binding for the Tk GUI toolkit. It also provides a few additional widgets more than the standard Tk ones.

Varjo is a Lisp to GLSL compiler. Vari is the dialect of lisp Varjo compiles. It aims to be as close to Common Lisp as possible, but naturally it is statically typed so there are differences.

Defstar is a collection of Common Lisp macros that can be used in place of defun, defmethod, defgeneric, defvar, defparameter, flet, labels, let* and lambda. Each macro has the same name as the form it replaces, with a star added at the end, e.g. defun. (the exception is the let* replacement, which is called *let).

This a Common Lisp library to parse HTML5 documents.

This library builds on the venerable idea of dynamically memoizing functions. A memoized function remembers results from previous computations and returns cached results when called again with the same arguments rather than repeating the computation.

Library to fuzzily parse time and date strings into a universal-time timestamp.

This package provides a canonical stand-in for NIL for contexts where NIL means no value.

With lispy syntax, shortcuts, and improvements, LASS aims to help you out in writing CSS quick and easy. LASS was largely inspired by SASS. LASS supports two modes, one being directly in your lisp code, the other in pure LASS files.

This package provides Common Lisp math and statistics routines.

This a Common Lisp library to convert geographic coordinates between latitude/longitude and UTM (Universal Transverse Mercator) or UPS (Universal Polar Stereographic).

Opticl is a Common Lisp library for representing, processing, loading, and saving 2-dimensional pixel-based images.

This library provides payment API wrappers over BTCPay, Paypal, and Stripe.

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

In Common Lisp, a special variable that is never dynamically bound typically serves as a stand-in for a global variable. The global-vars library provides true global variables that are implemented by some compilers. An attempt to rebind a global variable properly results in a compiler error. That is, a global variable cannot be dynamically bound.

Global variables therefore allow us to communicate an intended usage that differs from special variables. Global variables are also more efficient than special variables, especially in the presence of threads.

This package provides a Common Lisp system which has only one function to return the CPU count of the current system.

cl-webkit is a binding to WebKitGTK+ for Common Lisp, currently targeting WebKit version 2. The WebKitGTK+ library adds web browsing capabilities to an application, leveraging the full power of the WebKit browsing engine.

Ironclad is a cryptography library written entirely in Common Lisp. It includes support for several popular ciphers, digests, MACs and public key cryptography algorithms. For several implementations that support Gray streams, support is included for convenient stream wrappers.

Hunchentoot is a web server written in Common Lisp and at the same time a toolkit for building dynamic websites. As a stand-alone web server, Hunchentoot is capable of HTTP/1.1 chunking (both directions), persistent connections (keep-alive), and SSL.

CL-STRFTIME is a Common Lisp compiler for the strftime “language.”

CL-Ledger is a Common Lisp port of the Ledger double-entry accounting system.

This is a trivial utility for distinguishing between a process running in a real terminal window and a process running in a dumb one, e.g. emacs-slime.
