Overview

Rails plugin for using Marble as a template handler.

Marble has three output formats: text, JSON, and YAML. The template handler calls to_s, to_json, and to_yaml for each format, respectively.

Marble sets up a builder for you; simply use the marble variable to access the builder. To rename the builder to another, possibly shorter variable in order to save keystrokes, put the new variable name as the name of the block parameter:

marble.hash do |m|
  m.free 'toast'
end

Marble loads this module only if it can find ActionView.
