.on(event_type, options = {}, &block) ⇒ Object

Listen for life-cycle events in your Gumdrop file like this:

Gumdrop.on :start do |event|
  puts "Here we go!"
end

Complete list of events fired by Gumdrop:

:start
:before_scan
:scan
:after_scan
:before_generate
:generate
:after_generate
:before_generate_item
:generate_item
:after_generate_item
:before_build
:build
:after_build
:before_checksum
:checksum
:after_checksum
:before_render
:render
:after_render
:before_render_item
:render_item
:after_render_item
:before_write
:write
:after_write
:before_copy_file
:copy_file
:after_copy_file
:before_write_file
:write_file
:after_write_file
:end

In the block parem ‘event` you will have access to :site, the current executing site instance, and :payload, where applicable.

:render_item is a special event because you can add/override the compiled output by modifying ‘event.data.return_value`
