Scans files and directories for scrummy truffles. And by truffles, we mean shiny new features of HTML5, JavaScript APIs, CSS3, and friends. Obviously.

gem 'trufflepig', :require => 'trufflepig'

Send the truffle pig on its way:

search = Trufflepig::Search.new "path/to/file/or/directory"
search.perform

Then look what it found:

search.results

The results will consist of an array of feature objects, formatted exactly like the caniuse.com/html5please.com source data, containing a description of the feature as well as browser compatibility tables, and links to more info.

Add or update patterns with the correct caniuse.com key to data/patterns.json by running:

rake featurelist:fetch

The build task will merge that list with the source JSON and create data/features.json which will be used by the search:

rake featurelist:build

For convenience there is also a task that combines the two previous ones:

rake featurelist:update

• Respect filetypes when scanning for features (e.g. don't look for CSS features in HTML code)
• Command line interface
• ...

We love pull requests. If you want to submit a patch:

• Fork the project.
• Make your feature addition or bug fix.
• Write specs for it. This is important so nobody breaks it in a future version unintentionally.
• Push to your fork and send a pull request.
