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.

Montezuma is a text search engine library for Lisp based on the Ferret library for Ruby, which is itself based on the Lucene library for Java.

Simple library to create temporary directories.

This is a Common Lisp library to calculate std140 or std430 layouts for a glsl UBO/SSBO.

This package provides a PNG Common Lisp system to operate with Portable Network Graphics file format.

Zippy is a library for the PKWARE Zip archive format. It can read and write zip files. It features:

• archive inspection without extraction;

• Zip64 support;

• split archive support;

• PKWARE decryption;

• fast deflate decompression thanks to 3bz;

• operates on streams and vectors;

• can compress stream->stream;

• extensible for other encryption and compression mechanisms.

April compiles a subset of the APL programming language into Common Lisp. Leveraging Lisp's powerful macros and numeric processing faculties, it brings APL's expressive potential to bear for Lisp developers. Replace hundreds of lines of number-crunching code with a single line of APL.

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.

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))))

This package provides the Common Lisp part of the emacs-slite test runner.

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

CF is a Common Lisp library for doing computations using continued fractions.

CL-STORE is a portable serialization package which should give you the ability to store all Common Lisp data types into streams.

This library defines a way of treating Common Lisp packages as conduits which can sit between one or more implementation packages and users of those packages.

This library provides a simple multithreading worker mechanism.

My Way is a Sinatra-compatible URL routing library.

Germinal is a server for the Gemini protocol, written in Common Lisp.

This package provides a Common Lisp library for dice rolling and working with dice-roll statistics.

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

ARNESI is Common Lisp utilities library similar to ALEXANDRIA, ANAPHORA or GOLDEN-UTILS.

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

The Bordeaux-FFT library provides a reasonably efficient implementation of the Fast Fourier Transform and its inverse for complex-valued inputs, in portable Common Lisp.

This is a Common Lisp library for reading PNG images.

The canonical way to determine the size of a file in bytes, using Common Lisp, is to open the file with an element type of (unsigned-byte 8) and then calculate the length of the stream. This is less than ideal. In most cases it is better to get the size of the file from its metadata, using a system call.

This library exports a single function, file-size-in-octets. It returns the size of a file in bytes, using system calls when possible.
