This collection of utilities is useful in contexts where you want a macro that uses lambda-lists in some fashion but need more precise processing.

This package provides Common Lisp bindings for libev.

iterate is an iteration construct for Common Lisp. It is similar to the CL:LOOP macro, with these distinguishing marks:

• it is extensible,

• it helps editors like Emacs indent iterate forms by having a more lisp-like syntax, and

• it isn't part of the ANSI standard for Common Lisp.

This package provides Python style generators for Common Lisp. It also includes a port of itertools.

This package provides a macro commonly used in livecoding to enable continuing when errors are raised. Simply wrap around a chunk of code and it provides a restart called continue which ignores the error and carrys on from the end of the body.

This is a wrapper for the SDL2_TTF library used for loading fonts and creating text assets. The library, in it's current state, can load TTF and OTF fonts and render fonts with the three different rendering modes provided by the C library (solid, shaded, and blended). While Latin text, UTF8, UNICODE, and Glyph text rendering is available only Latin text has been tested (as shown in the examples).

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.

LLOG is a structured logging framework for Common Lisp with a sugared and a typed API, leveled logging (trace/debug/info/warn/error/fatal/panic), multiple encoders (console, JSON, s-expression and pattern) and stream/file/async outputs. Optional subsystems add REPL integration and tamper-evident, hash-chained audit trails.

NDebug provides a small set of utilities to make graphical (or, rather non-REPL-resident) Common Lisp applications easier to integrate with the standard Lisp debugger (*debugger-hook*, namely) and implementation-specific debugger hooks (via trivial-custom-debugger), especially in a multi-threaded context.

cl-incless implements print-object methods for many standard classes.

This library implements a basic promise datastructure, which is useful for dealing with asynchronous behaviours. Importantly, this library does not use any other libraries or frameworks, and instead leaves the execution and state transition of promise objects in your control, making it easy to integrate.

Html-entities is a Common Lisp library that lets you encode and decode entities in HTML.

Conium is a portability library for debugger- and compiler-related tasks in Common Lisp. It is fork of SWANK-BACKEND.

This library defines most Common Lisp standard macros that can be defined in a portable way and that can generate portable code. Some of these macros may not be good enough as the final version for a typical implementation, but they will work.

This is a lightweight, non-consing, optimized queue implementation for Common Lisp.

This package provides a grab bag of miscellaneous Common Lisp utilities.

This package provides a canonical stand-in for NIL for contexts where NIL means no value.

This package provides a Common Lisp implementation of Base64 encoding and decoding. Base64 encoding is a technique to encode binary data in a portable, safe printable, 7-bit ASCII format.

This package provides a compute-effective-slot-definition-initargs generic function that allows for more ergonomic initialization of effective slot definition objects.

cl-num-utils implements simple numerical functions for Common Lisp, including:

• num=, a comparison operator for floats

• simple arithmeric functions, like sum and l2norm

• elementwise operations for arrays

• intervals

• special matrices and shorthand for their input

• sample statistics

• Chebyshev polynomials

• univariate rootfinding

Parse-Declarations is a Common Lisp library to help writing macros which establish bindings. To be semantically correct, such macros must take user declarations into account, as these may affect the bindings they establish. Yet the ANSI standard of Common Lisp does not provide any operators to work with declarations in a convenient, high-level way. This library provides such operators.

The GTWIWTG library (Generators The Way I Want Them Generated -- technically not generators, but iterators) is meant to be small, explorable, and understandable.

atomichron is a Common Lisp library which implements a time meter which tracks how many times a form is evaluated, and how long evaluation takes. It uses atomic instructions so that meters will present correct results in the presence of multiple threads, while trying to minimize synchronization latency.

string-pokemonize provides a function that alternates uppercase and lowercase characters for a given string.
