Lemonad

Lemonad is a JavaScript library supporting functional programming inspired by Clojure, ClojureScript, Functional JavaScript, ML, Haskell, Forth and Underscore. It requires the presence of either Underscore or Lo-Dash and the Underscore-contrib libraries.

The main motivation for Lemonad is that my current work requires the use of JavaScript on the client side and ClojureScript is not an option. As a result I decided to try and capture the "feel" of a ClojureScript experience in the guise of JavaScript. Over time the library evolved to incorporate other influences while maintaining an adherence to operating with JavaScript core types. I thought this might be useful for others, so here it is. Enjoy.

Lemonad can be installed via NPM by adding the following to your package.json file:

"dependencies": {
  "lemonad": ">= 0.6.2",
}

You can also find the Lemonad source code on Github at http://github.com/fogus/lemonad.

Whether you use Lemonad via Node.js, within a web page or some other method, including the lemonad.js file defines a global variable named L that is used as the module for its capabilities.

On a web page, you'll need to do the following:

<script type="text/javascript" src="underscore.js"></script>
<script type="text/javascript" src="underscore.array.builders.js"></script>
<script type="text/javascript" src="underscore.array.selectors.js"></script>
<script type="text/javascript" src="underscore.function.combinators.js"></script>
<script type="text/javascript" src="underscore.function.predicates.js"></script>
<script type="text/javascript" src="underscore.util.existential.js"></script>
<script type="text/javascript" src="lemonad.js"></script>

An explicit dependency on Underscore version 1.4.0 or greater is required for now.

Documentation for using Lemonad is in development. For now you can look at the Lemonad specs and their source code to get a feel for using it.

Remember, contibutions welcomed.
