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

Usage

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.

Adding or updating detection patterns

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

To do

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