This library provides a uniform API, as specified in Common Lisp the Language 2, for accessing information about variable and function bindings from implementation-defined lexical environment objects. All major Common Lisp implementations are supported, even those which don't support the CLTL2 environment access API.

This package provides highly optimized base64 encoding and decoding. Besides conversion to and from strings, integer conversions are supported. Encoding with Uniform Resource Identifiers is supported by using a modified encoding table that uses only URI-compatible characters.

Envy is a configuration manager for various applications. Envy uses an environment variable to determine a configuration to use. This can separate configuration system from an implementation.

Babel is a charset encoding and decoding library, not unlike GNU libiconv, but completely written in Common Lisp.

This is a Common Lisp library which provides functionality to read/write Bit Map Font (BMF) into text, JSON and XML.

This package provides functions for generating lorem ipsum text.

Transducers are an ergonomic and extremely memory-efficient way to process a data source. Data source refers to simple collections like lists or vectors, but also potentially large files or generators of infinite data.

This package provides the CL-SVG Common Lisp system to produce Scalable Vector Graphics files.

TRIVIAL-OCTET-STREAMS is a Common Lisp library implementing in-memory octet streams analogous to string streams.

HELambdap is a Common Lisp documentation system which strives to be simple to use, yet easily customizable.

Trivia is a pattern matching compiler that is compatible with Optima, another pattern matching library for Common Lisp. It is meant to be faster and more extensible than Optima.

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

Utility library for handling bit vectors, bit vector arithmetic, and universal integer type conversions between bit-vectors, byte-vectors, octals, decimals, and hexadecimal notation.

This library provides a WebSocket server and client implementation for Common Lisp.

fmt provides an alternative to the Common Lisp format function by utilizing s-expressions for formatting directives instead of control strings.

This library is a collection of pseudo random number generators.

While Common Lisp does provide a RANDOM function, it does not allow the user to pass an explicit SEED, nor to portably exchange the random state between implementations. This can be a headache in cases like games, where a controlled seeding process can be very useful.

For both curiosity and convenience, this library offers multiple algorithms to generate random numbers, as well as a bunch of generally useful methods to produce desired ranges.

This is a library to provide cross-platform access to gamepads, joysticks, and other such HID devices.

This is a Common Lisp library providing a unified way to work with package locks across supported Common Lisp implementations.

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.

trivial-clipboard gives access to the system clipboard.

This library provides two strata to access the POSIX shm API:

• the package posix-shm/ffi, a collection of slim bindings to the POSIX API

• the package posix-shm, a lispy wrapper around the FFI that integrates more closely to the features of Common Lisp, and provides a handful of utilities and macros

Features include:

• open, close, create, resize, change ownership of, change permissions of, and memory map to shared memory objects

• open-shm appears more like open from the standard library

• open-shm*, for creating anonymous shm objects

• with-open-shm, with-mmap and similar with- macros for safely accessing resources with dynamic extent

HTML parser/emitter for CommonDoc.

jsown is a high performance Common Lisp JSON parser. Its aim is to allow for the fast parsing of JSON objects in Common Lisp. Recently, functions and macros have been added to ease the burden of writing and editing jsown objects.

jsown allows you to parse JSON objects quickly to a modifiable Lisp list and write them back. If you only need partial retrieval of objects, jsown allows you to select the keys which you would like to see parsed. jsown also has a JSON writer and some helper methods to alter the JSON objects themselves.

jzon is a correct and safe JSON RFC 8259 parser for Common Lisp.
