With static-vectors, you can create vectors allocated in static memory.

This library generates sdf (https://steamcdn-a.akamaihd.net/apps/valve/2007/SIGGRAPH2007_AlphaTestedMagnification.pdf), psdf and msdf (https://github.com/Chlumsky/msdfgen/files/3050967/thesis.pdf) atlases.

The Babel library solves a similar problem while understanding more encodings. Trivial UTF-8 was written before Babel existed, but for new projects you might be better off going with Babel. The one plus that Trivial UTF-8 has is that it doesn't depend on any other libraries.

This system implements a general definitions introspection library. It gives you the ability to retrieve definitions or bindings associated with designators such as symbols, packages, and names in general. For instance, it allows you to retrieve all function, type, variable, method, etc. definitions of a symbol.

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.

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

This package parses and prints dates in RFC-1123 format.

This package provides a standard interface to the various package lock implementations of Common Lisp.

This library provides trivial percent encoding and decoding functions for URLs.

THE-COST-OF-NOTHING is a library for measuring the run time of Common Lisp code. It provides macros and functions for accurate benchmarking and lightweight monitoring. Furthermore, it provides predefined benchmarks to determine the cost of certain actions on a given platform and implementation.

This library implements various functions to access status information about the machine, process, etc.

This is only useful if you want to start a Swank server in a Lisp processes that doesn't run under Emacs. Lisp processes created by M-x slime automatically start the server.

Scrape on-line documentation out of a running Lisp image.

This is a Common Lisp library for simplifying packaging and loading of compiled foreign library collection.

This is a Common Lisp library to present tabular data in ascii-art tables.

generic-cl provides a generic function wrapper over various functions in the Common Lisp standard, such as equality predicates and sequence operations. The goal of this wrapper is to provide a standard interface to common operations, such as testing for the equality of two objects, which is extensible to user-defined types.

CXML does an excellent job at parsing XML elements, but what do you do when you have a XML file that's larger than you want to fit in memory, and you want to extract some information from it? Writing code to deal with SAX events, or even using Klacks, quickly becomes tedious. cl-xmlspam (for XML Stream PAttern Matcher) is designed to make it easy to write code that mirrors the structure of the XML that it's parsing. It also makes it easy to shift paradigms when necessary - the usual Lisp control constructs can be used interchangeably with pattern matching, and the full power of CXML is available when necessary.

simple-neural-network is a Common Lisp library for creating, training and using basic neural networks. The networks created by this library are feedforward neural networks trained using backpropagation.

Often times we need to destructure a form definition in a Common Lisp macro. This library provides a set of simple utilities to help with that.

Schemeish implements several useful Scheme constructs for Common Lisp. These include named-let, define, scheme argument lists, and a shortcut to FUNCALL with [] instead of ().

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.

simple-routes is a simple Common Lisp RESTful routing facility on top of Hunchentoot.

This package provides GNU gettext completely implemented in Common Lisp without any C library bindings.
