Overview

Watches for changes in configured files and regenerated them as they are changed.

Just pass the name of the resource to it and call #start. It will generate the files right away and it will keep watching for changes in those files. Every time a file is added, changed or removed, it will regenerate all files.

You can also pass a block when initializing to create and configure the resource.

For example:

watcher = Smartgen::Watcher.new :my_resource do |config|
  config.src_files = ['docs/**/*']
  config.output_folder = 'public_docs'
end

watcher.start
