Chemboy is a Common Lisp program for doing basic chemistry calculations. This package provides the text-based interface for Chemboy.

F2cl is a Common Lisp library that can convert Fortran 77 code into Common Lisp code.

Retrospectiff is a common lisp library for reading and writing images in the TIFF (Tagged Image File Format) format.

A modern and consistent Common Lisp string manipulation library that focuses on modernity, simplicity and discoverability: (str:trim s) instead of (string-trim '(#\Space ...) s)), or str:concat strings instead of an unusual format construct; one discoverable library instead of many; consistency and composability, where s is always the last argument, which makes it easier to feed pipes and arrows.

This package implements an algorithm for the spelling of enharmonics and dealing with ties and dots in rhythm notation.

This package provides a Common Lisp library for fetching and parsing RSS feeds data via HTTP. Currently, it supports RSS versions 0.90, 0.91, and 0.92 as well as RSS version 2.

This package provides Common Lisp support for reading the Terragen .TER format. The format specification can be found at https://planetside.co.uk/wiki/index.php?title=Terragen_.TER_Format

When dealing with network protocols and file formats, it's common to have to read or write 16-, 32-, or 64-bit datatypes in signed or unsigned flavors. Common Lisp sort of supports this by specifying :element-type for streams, but that facility is underspecified and there's nothing similar for read/write from octet vectors. What most people wind up doing is rolling their own small facility for their particular needs and calling it a day.

This library attempts to be comprehensive and centralize such facilities. Functions to read 16-, 32-, and 64-bit quantities from octet vectors in signed or unsigned flavors are provided; these functions are also SETFable. Since it's sometimes desirable to read/write directly from streams, functions for doing so are also provided. On some implementations, reading/writing IEEE singles/doubles (i.e. single-float and double-float) will also be supported.

BOOST-PARSE is a simple token parsing library for Common Lisp.

This library is a path strings manipulation library inspired by Python's os.path. All functionality from os.path is supported on major operation systems.

The philosophy behind is to use simple strings and "dumb" string manipulation functions to handle paths and filenames. Where possible the corresponding OS system functions are called.

This is a library for reading semi-raw user input from terminals. Semi-raw as in, we can't detect if the user pressed the Control key alone, and the function keys are a mystery. What is supported, however, is:

• Regular characters

• Control+[key]

• Alt+[key]

• Control+Alt+[key]

High performance JSON encoder and decoder. Currently support: SBCL, CCL.

This package provides a Common Lisp bindings to glfw, an OpenGL application development library.

This is a Commin Lisp library for operating on permutations and permutation groups.

This is a wrapper library to allow you to interface with the Valve SteamWorks API.

This is a teensy library that provides some functions to determine the mime-type of a file.

This is a (currently) brief but usable wrap for SDL2_image.

This package provides tools for manipulating data in files using data frames.

cl-pass is a password hashing and verification library.

Clip is an attempt at a templating library that allows you to write templates in a way that is both accessible to direct webdesign and flexible. The main idea is to incorporate transformation commands into an HTML file through tags and attributes. Clip is heavily dependent on Plump and lQuery.

colorize is a Lisp library for syntax highlighting supporting the following languages: Common Lisp, Emacs Lisp, Scheme, Clojure, C, C++, Java, Python, Erlang, Haskell, Objective-C, Diff, Webkit.

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

Vernacular is a build and module system for languages that compile to Common Lisp. It allows languages to compile to Lisp while remaining part of the Common Lisp ecosystem. Vernacular languages interoperate with Common Lisp and one another.

Vernacular handles locating files, compiling files into FASLs, tracking dependencies and rebuilding, and export and import between your new language, Lisp, and any other language Vernacular supports.

Vernacular builds on Overlord and is inspired by Racket.

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.).
