programming has a number of common, idiomatic operations: maps,\nfolds, currying and so on. There are a number of excellent JavaScript libraries\nwhich provide access to these fundamentals in a more-or-less functional style.\n[Ojay]'s core extensions, Oliver Steele's [Functional] and Jeremy Ashkenas'\n[Underscore] are all good examples.\n\n[Udon] is cast in a similar mould to the above. It aims to provide basic\nsupport for functional programming in JavaScript, initially by porting some\nelements of Haskell's `Data.List` library.\n\n[Udon]:       http://extralogical.net/projects/udon/\n[Ojay]:       http://ojay.othermedia.org/\n[Underscore]: http://documentcloud.github.com/underscore/\n[Functional]: http://osteele.com/sources/javascript/functional/\n\n\nInstalling Udon\n---------------\n\nUdon is available from [npm], so if you want to use Udon with [Node] you can\njust run the following command to globally install the library.\n\n    npm install -g udon\n\nThen it's just a matter of requiring it in your Node project. The module\nexported by the library is just the top-level Udon object.\n\n    var Udon = require('udon');\n    \n    Udon.sum([1, 2, 3, 4]); // -\u003e 10\n\nOtherwise, you can grab pre-built versions from the [Udon website][Udon] or\nbuild it yourself as described below.\n\n[npm]:  http://npmjs.org/\n[Node]: http://nodejs.org/\n\n\nBuilding the library\n--------------------\n\nIf you've checked out the Git repository and want to build a minified version\nof the library from source, you will need [Ruby], [Rubygems] and the [Jake]\ngem, which you can get by running (with `sudo` if you like)\n\n    gem install jake\n\nfrom the command line. Then just `cd` into your Udon directory and run\n\n    jake\n\nwhich will build the library in the `/pkg` directory.\n\n[Ruby]:     http://ruby-lang.org\n[Rubygems]: http://rubygems.org\n[Jake]:     https://github.com/jcoglan/jake\n\n\nDeploying with Helium\n---------------------\n\nUdon includes a `jake.yml` file for use with the Jake build tool, as explained\nabove. This also means that it is easily deployed with [Helium], a Git-backed\nJavaScript package server. It should also fit into any other build or deploy\nsystem based on [JS.Packages].\n\n[Helium]:      https://github.com/othermedia/helium\n[JS.Packages]: http://jsclass.jcoglan.com/packages.html\n\n\nRunning the test suite\n----------------------\n\nThe Udon test suite is written with the [JS.Test] testing framework. The test\nsuite runs on several JavaScript platforms, including [Node] and all modern web\nbrowsers.\n\nTo run the test suite from the command line, run the following command\n(replacing `node` with [Rhino], [V8] etc. where relevant).\n\n    node test/console.js\n\nTo run the test suite in a browser, open the `test/browser.html` file in a web\nbrowser.\n\n[JS.Test]: http://jsclass.jcoglan.com/testing.html\n[Node]:    http://nodejs.org\n[Rhino]:   http://www.mozilla.org/rhino/\n[V8]:      http://code.google.com/p/v8/\n\n\nBuilding the Udon website\n-------------------------\n\nThe website is built with [Hakyll], a static site generator written in\n[Haskell]. To build it you will need [GHC] and [cabal-install]; the simplest\nway to get hold of these is to install the [Haskell Platform]. You'll also need\nto install the `hakyll` package from [Hackage]:\n\n    cabal install hakyll\n\nThen, to build the site, just run this from your Udon directory:\n\n    ghc --make -Wall site/site\n\n[Hakyll]:           http://jaspervdj.be/hakyll/\n[Haskell]:          http://www.haskell.org\n[GHC]:              http://www.haskell.org/ghc/\n[cabal-install]:    http://www.haskell.org/cabal/download.html\n[Haskell Platform]: http://hackage.haskell.org/platform/\n[Hackage]:          http://hackage.haskell.org/\n","funding_links":[],"categories":["Libraries"],"sub_categories":["[Javascript](https://developer.mozilla.org/en-US/docs/Web/JavaScript)"],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbeastaugh%2Fudon","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fbeastaugh%2Fudon","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fbeastaugh%2Fudon/lists"}
