A small collection of common lisp macros to make collecting values easier.

EXTERNAL-PROGRAM enables running programs outside the Lisp process. It is an attempt to make the RUN-PROGRAM functionality in implementations like SBCL and CCL as portable as possible without sacrificing much in the way of power.

POLICY-COND provides tools to insert and execute code based on a compiler's OPTIMIZE policy. It also contains a contract-like notion of expectations, which allow dynamic checking or inclusion of various things that should happen depending on compiler policy.

clingon is a command-line option parsing library for Common Lisp. Its features include:

• Support for subcommands

• Support for command aliases

• Support for short and long options

• Related options may be grouped into categories

• Short options may be collapsed into a single argument, as in -xyz

• Long options support the notations --long-opt arg and --long-opt=arg

• Automatic generation of help/usage information for commands and subcommands

• Out-of-the-box support for --version and --help

• Support for various kinds of options including string, integer, boolean, switch, enum, list, counter, filepath, etc.

• Subcommands can look up global options defined in parent commands

• Support for required options

• Options can be initialized via environment variables

• Single interface for creating options using CLINGON:MAKE-OPTION

• Generate documentation for your command-line application

• Support for pre-hook and post-hook actions for commands, which allow invoking functions before and after the respective handler of the command is executed

• Support for Bash and Zsh completions

• Extensibility, so if you don't find something you need you can extend it by developing a new option kind, or even a new mechanism for initializing options, e.g., by looking up an external key/value store

Eager Future2 is a Common Lisp library that provides composable concurrency primitives that unify parallel and lazy evaluation, are integrated with the Common Lisp condition system, and have automatic resource management.

This is a Common Lisp library for creating PNG images.

This library provides functions for determining the value types of Common Lisp forms, based on type information contained in the environment.

In order for this library to work the values types of variables and return types of functions have to be declared.

Macros and symbol-macros are fully expanded and all special forms, except CATCH, are supported.

Anaphora is the anaphoric macro collection from Hell: it includes many new fiends in addition to old friends like aif and awhen.

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.

The Common Lisp Application Directories (CLAD) library is a simple API collection that provides access to a set of standard Common Lisp folders on a per-application or per-library basis.

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

This project is meant to provide tools for internationalizing Common Lisp programs.

One important aspect of internationalization is of course the language used in error messages, documentation strings, etc. But with this project we provide tools for all other aspects of internationalization as well, including dates, weight, temperature, names of physical quantities, etc.

OpenAPI client system generator.

This is a Common Lisp library providing functions to read/write CSV from/to strings, streams and files.

This package provides first-class global environments for Common Lisp.

This package provides a Common Lisp templating system based on Python Django with a syntax similar to Python Jinja2.

A simple Common-Lisp interface to the underlying operating system. It's independent of the implementation and operating system.

Binary-types is a Common Lisp package for reading and writing binary files. Binary-types provides macros that are used to declare the mapping between Lisp objects and some binary (i.e. octet-based) representation.

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

LTK is a Common Lisp binding for the Tk graphics toolkit. It is written in pure Common Lisp and does not require any Tk knowledge for its usage.

This package provides Common Lisp bindings to create OpenGL window and context manipulation code as well as system input handling. Direct FFI bindings to system functions are used so no third party C lib is required except system libraries.

This package provides a Common Lisp parser for glTF file format.

This package provides a utility library intended at providing configurable reader macros for common tasks such as accessors, hash-tables, sets, uiop:run-program, arrays and a few others.

Library to fuzzily parse time and date strings into a universal-time timestamp.
