HypeAssets

HypeAssets provides Rails Asset Pipeline integration for Tumult Hype 3 animations.

Tumult Hype is a tool for producing animations and interactive content implemented as HTML5 javascripts and images. Integrating these into the Rails Asset Pipeline would enable serving these resources from a CDN and versioning them with Digest Fingerprinting. That integration is, unfortunately, difficult to do. Rails expects that all file references be encapsulated with asset_path() calls within ERB tags, while Tumult Hype produces a minified javascript file containing image filenames that are each concatenated client-side onto a single base URL.

HypeAssets makes Rails Asset Pipeline integration easy by automatically modifying the foo_hype_generated_script.js file with the correct file references.

HypeAssets is designed to work with animations built with Tumult Hype version 3, using HYPE-4xx or HYPE-5xx runtime scripts. (It has been tested with HYPE-456, HYPE-466, and HYPE-526.)

It also requires Sprockets 3.x, as they redesigned their asset processor API.

Add this line to your application‘s Gemfile:

gem 'hype_assets'

And then execute:

$ bundle

1. Create a folder for your hype animations. I recommend app/assets/hype, but any folder in your assets search path will do.

2. Copy your foo.hyperesources folders into that folder.

3. Append a .hype extension to your hype scripts:

   $ cd app/assets/hype/foo.hyperesources
   $ mv foo_hype_generated_script.js foo_hype_generated_script.js.hype
   

   NOTE: Do NOT rename your other javascript files, e.g. HYPE-123.full.min.js.

4. In your HTML, reference your hype animation script with

   <%= javascript_include_tag "foo.hyperesources/foo_hype_generated_script.js" %>
   

Bug reports, pull requests, and general feedback are welcome on GitHub at https://github.com/nmagedman/hype_assets/issues.

If your hype animation works when run from a static page but fails when run via HypeAssets, please send me a zip of the foo.hyperesources folder and a foo.html container page. Attach it to the github issue or email it to nmagedman+hype@gmail.com.
