This package provides a canonical way of converting generalized booleans to booleans.

This package provides KONS-9 which can be considered as a traditional user interface driven 3D application for general artists, or as a REPL-based development environment for technical artists and software developers. These two approaches can be seamlessly combined into a flexible and powerful workflow, where non-technical users can immediately benefit from software tools and extensions developed by technical users.

defclass-star provides defclass* and defcondition* to simplify class and condition declarations. Features include:

• Automatically export all or select slots at compile time.

• Define the :initarg and :accessor automatically.

• Specify a name transformer for both the :initarg and :accessor, etc.

• Specify the :initform as second slot value.

See https://common-lisp.net/project/defclass-star/configuration.lisp.html for an example.

This package provides a Common Lisp system helping in scripting, it uses uiop:run-program as a backend.

This is a YAML parser and emitter for Common Lisp built on top of libyaml.

trivial-garbage provides a portable API to finalizers, weak hash-tables and weak pointers on all major implementations of the Common Lisp programming language.

Clack is a web application environment for Common Lisp inspired by Python's WSGI and Ruby's Rack.

This is a very simple color library for Common Lisp, providing:

• Types for representing colors in HSV, HSL, and RGB spaces.

• Simple conversion functions between the above types.

• Function printing colors to HEX, RGB, RGBA, and HSL.

• Predefined colors from X11, SVG, and GDK.

This package provides CFFI bindings for Common Lisp to the Cairo C library.

This is a Common Lisp library that implements the 9p network filesystem protocol.

CMN provides a package of functions to hierarchically describe a musical score. When evaluated, the musical score is rendered to an image.

Metatilities-base is the core of the metatilities Common Lisp library which implements a set of utilities.

This is a Common Lisp package for hash table creation with flexible, extensible initializers.

In the crowded space of Common Lisp HTML generators, Spinneret occupies the following coordinates:

• Modern. Targets HTML5. Does not treat XML and HTML as the same problem. Assumes you will be serving your documents as UTF-8.

• Composable. Makes it easy to refactor HTML generation into separate functions and macros.

• Pretty. Treats HTML as a document format, not a serialization. Output is idiomatic and readable, following the coding style of the HTML5 specification.

• Aggressive. If something can be interpreted as HTML, then it will be, meaning that some Lisp forms can't be mixed with HTML syntax. In the trade-off between 90% convenience and 10% correctness Spinneret is on the side of convenience.

• Bilingual. Spinneret (after loading spinneret/ps) has the same semantics in Lisp and Parenscript.

This is a Common Lisp library to read and write disk-based file archives such as those generated by the tar and cpio programs on Unix.

Stealth-mixin is a Common Lisp library for creating stealth mixin classes. These are classes that are dynamically mixed into other classes without the latter being aware of it.

This system implements a general definitions introspection library. It gives you the ability to retrieve definitions or bindings associated with designators such as symbols, packages, and names in general. For instance, it allows you to retrieve all function, type, variable, method, etc. definitions of a symbol.

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

Bobbin is a simple word-wrapping library for strings in Common Lisp. It aims to be simple, work nicely for the majority of cases, and degrade gracefully for edge cases. It is not particularly concerned with speed — if you need very high-performance word wrapping, Bobbin is not for you.

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.

IOlib is to be a better and more modern I/O library than the standard Common Lisp library. It contains a socket library, a DNS resolver, an I/O multiplexer(which supports select(2), epoll(4) and kqueue(2)), a pathname library and file-system utilities.

This is a minimalistic parser of command line options. The main advantage of the library is the ability to concisely define command line options once and then use this definition for parsing and extraction of command line arguments, as well as printing description of command line options (you get --help for free). This way you don't need to repeat yourself. Also, unix-opts doesn't depend on anything and precisely controls the behavior of the parser via Common Lisp restarts.

Caveman is intended to be a collection of common parts for web applications. Caveman2 has three design goals:

• Be extensible.

• Be practical.

• Don't force anything.

The NUMPY-FILE-FORMAT library is a Common Lisp library for reading and writing NumPy .npy and .npz files.
