This is a very simple implementation of SHA1 and HMAC-SHA1 for Common Lisp. The code is intended to be easy to follow and is therefore a little slower than it could be.

Additional dolist style macros for Common Lisp, such as doalist, dohash, dolist*, doplist, doseq and doseq*.

Dexador is yet another HTTP client for Common Lisp with neat APIs and connection-pooling. It is meant to supersede Drakma.

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

exit-hooks provides a portable way to automatically call some user-defined function when exiting Common Lisp (both quit from the REPL or a kill in a shell). Like atexit in C and Python or Java’s Runtime.addShutdownHook(). It currently supports SBCL, CCL, ECL, ABCL, Allegro CL, clisp and CMUCL. Before exit-hooks, there was no portable way of doing so and no staightforward way to use an exit hook on ABCL. It can be used for tasks like parmenantly save something when exiting Lisp.

RTG-MATH provides a selection of the math routines most commonly needed for making realtime graphics in Lisp.

The Type-Templates library allows you to define types and “template functions” that can be expanded into various type-specialized versions to eliminate runtime dispatch overhead. It was specifically designed to implement low-level numerical data types and functionality.

This package provides a pure-lisp implementation of a DNS client. It can be used to resolve hostnames, reverse-lookup IP addresses, and fetch other kinds of DNS records.

Small library aiming to cut down time spent moving data between CLOS and JSON objects. It depends on YASON and it should be possible to use it alongside straight calls to functions from YASON.

This is an optimized Common Lisp library of Bob Jenkins' ISAAC-32 and ISAAC-64 algorithms, which are fast cryptographic random number generators: Indirection, Shift, Accumulate, Add, and Count.

This package ensures that special subclasses of standard-object cluster right in front of standard-object in the class precedence list.

This library exports three symbols: with-raw-io, read-char, and read-line, to provide raw POSIX I/O in Common Lisp.

STMX is a high-performance implementation of composable Transactional Memory, which is a concurrency control mechanism aimed at making concurrent programming easier to write and understand. Instead of traditional lock-based programming, one programs with atomic memory transactions, which can be composed together to make larger atomic memory transactions.

A memory transaction gets committed if it returns normally, while it gets rolled back if it signals an error (and the error is propagated to the caller).

Finally, memory transactions can safely run in parallel in different threads, are re-executed from the beginning in case of conflicts or if consistent reads cannot be guaranteed, and their effects are not visible from other threads until they commit.

Memory transactions give freedom from deadlocks, are immune to thread-safety bugs and race conditions, provide automatic roll-back on failure, and aim at resolving the tension between granularity and concurrency.

Common Lisp port of Universal Tween Engine.

This is a portable Universal Resource Identifier library for Common Lisp programs. It parses URI according to the RFC 2396 specification.

Eclector is a portable Common Lisp reader that is highly customizable, can recover from errors and can return concrete syntax trees.

In contrast to many other reader implementations, eclector can recover from most errors in the input supplied to it and continue reading. This capability is realized as a restart.

It can also produce instances of the concrete syntax tree classes provided by the concrete syntax tree library.

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

This is a Common lisp library to unify access to the most common dictionary-like data structures.

postmodern is a Common Lisp library for interacting with PostgreSQL databases. It provides the following features:

• Efficient communication with the database server without need for foreign libraries.

• Support for UTF-8 on Unicode-aware Lisp implementations.

• A syntax for mixing SQL and Lisp code.

• Convenient support for prepared statements and stored procedures.

• A metaclass for simple database-access objects.

This package produces 4 systems: postmodern, cl-postgres, s-sql, simple-date

SIMPLE-DATE is a very basic implementation of date and time objects, used to support storing and retrieving time-related SQL types. It is not loaded by default and you can use local-time (which has support for timezones) instead.

S-SQL is used to compile s-expressions to strings of SQL code, escaping any Lisp values inside, and doing as much as possible of the work at compile time.

CL-POSTGRES is the low-level library used for interfacing with a PostgreSQL server over a socket.

POSTMODERN itself is a wrapper around these packages and provides higher level functions, a very simple data access object that can be mapped directly to database tables and some convenient utilities. It then tries to put all these things together into a convenient programming interface

Mito is yet another object relational mapper, and it aims to be a successor of Integral.

• Support MySQL, PostgreSQL and SQLite3.

• Add id (serial/uuid primary key), created_at and updated_at by default like Ruby's ActiveRecord.

• Migrations.

• Database schema versioning.

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.

Hunchenissr works together with issr.js for the development of interactive (changing without page refreshes) websites making use of websocket and Common Lisp server HTML generation instead of mountains of convoluted Javascript.

This is a Common Lisp library that publishes D-Bus objects as well as send and notify other objects connected to a bus.

This library implements efficient algorithms that calculate various string metrics in Common Lisp:

• Damerau-Levenshtein distance

• Hamming distance

• Jaccard similarity coefficient

• Jaro distance

• Jaro-Winkler distance

• Levenshtein distance

• Normalized Damerau-Levenshtein distance

• Normalized Levenshtein distance

• Overlap coefficient
