Trivial-Benchmark runs a block of code many times and outputs some statistical data for it. On SBCL this includes the data from time, for all other implementations just the real-time and run-time data. However, you can extend the system by adding your own metrics to it, or even by adding additional statistical computeations.

This package provides an enhanced version of typep that is exactly like the one in the Lisp spec, except it can also accept a single type argument, in which case it returns the appropriate closure.

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

cl-mysql is a Common Lisp implementation of a MySQL wrapper.

This Common Lisp library provides functions for Zstandard compression/decompression using bindings to the libzstd C library.

Arrow-macros provides clojure-like arrow macros (ex. ->, ->>) and diamond wands in swiss-arrows.

The 3D-Spaces library implements a number of spatial query data structures; structures that can answer spatial range queries for optimized lookup, particularly suited for games.

This is a backend for the linear-programming Common Lisp library using the GNU Linear Programming Kit (GLPK) library.

This package provides CFFI bindings and interface to Allegro 5 game developing library for Common Lisp.

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

RUTILS is a syntactic utilities package for Common Lisp.

This is a Common Lisp kernel for Jupyter along with a library for building Jupyter kernels, based on Maxima-Jupyter which was based on cl-jupyter.

This is a c2ffi-based wrapper generator for Common Lisp.

definitions-systems provides a simple unified extensible way of processing named definitions.

cl-rucksack is a persistence library based on Arthur Lemmens' Rucksack with some enhancements.

This package provides a hierarchy of major functions and auxiliary functions related to the structured analysis and processing of open text.

This package provides a client for SMTP.

parse-number is a library of functions for parsing strings into one of the standard Common Lisp number types without using the reader. parse-number accepts an arbitrary string and attempts to parse the string into one of the standard Common Lisp number types, if possible, or else parse-number signals an error of type invalid-number.

Datafly is a lightweight database library for Common Lisp.

This Common Lisp library implements object prevalence (see https://en.wikipedia.org/wiki/System_prevalence). It allows for (de)serializing to and from s-exps as well as XML. Serialization of arbitrary classes and cyclic data structures are supported.

For is a library for an extensible iteration macro. It allows you to write concise looping constructs similar to loop and iterate. Unlike loop however it is extensible and sensible, and unlike iterate it does not require code-walking and is easier to extend.

This package extends the Common Lisp reader syntax such that is accepts Org files as Lisp source code files.

Max’s Parser Combinators is a simple and pragmatic library for writing parsers and lexers based on combinatory parsing. MaxPC is capable of parsing deterministic, context-free languages, provides powerful tools for parse tree transformation and error handling, and can operate on sequences and streams. It supports unlimited backtracking, but does not implement Packrat Parsing. Instead, MaxPC achieves good performance through its optimized primitives, and explicit separation of matching and capturing input. In practice, MaxPC parsers perform better on typical computer languages—when compared to Packrat parsers—at the expense of not producing linear-time parsers.

This library allows you to open native file dialogs to open and save files. This is useful if you have an application that's primarily text based and would like a more convenient file selection utility, or if you are working with a UI toolkit that does not offer a way to access the native file dialogs directly.
