A functional object operations library.

Maddy

Maddy is a functional object operations library. It provides various higher-order functions for manipulating object members, as well as utility methods for determining deep equality, checking object types, and recursively inspecting objects. All recursive methods fully support cyclic structures.

Maddy is directly inspired by Functional, Underscore, and Ruby's Enumerable module, and philosophically by the FuseJS project.

The library is framework-agnostic, and is compatible with web browsers, CommonJS environments, JavaScript engines, and asynchronous script loaders. It also normalizes infamous bugs present in older environments, such as Internet Explorer 6 and Safari 2.

Downloads

The development version is commented and uncompressed; the production version has been compressed using Closure Compiler with advanced optimizations enabled.

Contributing to Maddy

Check out a working copy of the Maddy source code with Git:

$ git clone git://github.com/kitcambridge/maddy.git

If you'd like to contribute a feature or bug fix, you can fork Maddy, commit your changes, and send a pull request. Please make sure to update the unit tests in the tests directory as well.

Alternatively, you can use the GitHub issue tracker to submit bug reports and feature requests.

Unit Tests

Maddy uses the Spec unit testing framework. The unit tests are written in Coco, a self-hosting CoffeeScript dialect that compiles to JavaScript. Coco reduces the syntactic noise and idiomatic verbosity inherent in writing unit tests for a functional programming library.

Coco can be installed via npm or Git. Once you've installed the compiler, run coco -wc tests/tests.co from the command line to watch and automatically recompile the unit tests as you modify them.

Coding Guidelines

In addition to the following Prototype-inspired guidelines, please follow the conventions already established in the code.

• Spacing: Use two spaces for indentation. No tabs.
• Naming: Keep variable and method names concise but descriptive. index and callback are preferable to i and fn.
• Functions: Use named function declarations to aid in debugging. Avoid anonymous functions and named function expressions.
• Comments: Significant changes and new methods should be annotated with comments.
• Lint: Make sure that your changes pass JavaScript Lint. A configuration file is included in the repository; to check the source code for problems, run jsl -conf jsl.conf.
