opal-raphael

Opal binding for Raphael.js.

Tested with Opal 0.6.2, Raphael 2.1.2.

Example

  paper = Raphael(0, 0, 600, 600)

  background = paper.rect(0, 0, 600, 600)
  background.attr("fill", "#efefef")
  background.attr("stroke", "#efefef")

See example/app/application.rb for full example.

Status

Early alpha

• Can render circle and rect
• Animation, Matrix, Raphael.*, Set, eve are not supported (Waiting for your pull request!)

See opal/opal-raphael.rb for list of supported methods.

• (Note1: some of the methods may return raw JS object. It should be wrapped with Raphael::Element, etc.)
• (Note2: method names are intentionally kept lowerCamelCase, so that you can find corresponding Opal method easily)

Getting started

1. Copy example/* to somewhere

2. Edit Gemfile

• before: gem 'opal-raphael', path: '../'
• after: gem 'opal-raphael'

1. bundle install

2. bundle exec rackup

3. Open http://localhost:9292/
