Paperjs

Paper.js — The Swiss Army Knife of Vector Graphics Scripting.

This gem bundles the upstream distribution for use with the Ruby on Rails framework. The version number of the gem always tracks the upstream javascript release and the gem itself doesn't provide any additional methods or helpers. If a need for helpers arises in the future they will be developed as a separate gem with this one as its dependency. Should a gem bug be discovered an additional version identifier will be appended and incremented after the upstream version number.

The original paper.js code distributed with this gem is licensed under MIT You can find the paper.js license file in the vendor directory, changes made to the original code base are as follows:

• none so far

Add this line to your application's Gemfile:

gem 'paperjs'

And then execute:

$ bundle

Or install it yourself as:

$ gem install paperjs

If you want to just use the Javascript paper.js API without paperscript support add the following in application.js:

//= paper-core

If you wish to user paperscript in your rails application include the following instead:

//= paper-full

Paperscript files should be included as type text/paperscript, you can set up the rails asset pipeline to handle this without mixing your paperscript and javacsript files.

Create a new folder app/assets/paperscripts and add it to config/initializers/assets.rb

Rails.application.config.assets.paths << Rails.root.join('app', 'assets', 'paperscripts')

additionally add application.paper.js to precompiled assets in the same file (config/initializers/assets.rb)

Rails.application.config.assets.precompile += %w( application.paper.js )

create the file app/assets/paperscripts/application.paper.js and set it up to include all files in it's directory

//= require_tree .

finally in your main application.html.erb add a javascript_include_tag for it:

    <%= javascript_include_tag('application.paper', type: "text/paperscript", canvas: "canvas-1") %>

note that with multiple paperscripts intended for more than one canvas you will either have to include them separately or manage PaperScope/canvas binding from javascript/paperscript.
