Overview

A rake task that starts a watcher for file changes and generate them on demand, using smartgen.

To use it, require this file instead of smartgen:

require 'smartgen/watcher_rake_task'

Then create the task and configuration:

Smartgen::WatcherRakeTask.new :generate_doc do |config|
  config.src_files = ['doc/**/*']
  config.output_folder = 'public/doc'
end

It yields a Configuration, in fact it calls Resource#configure, so you can use any of the configurations here.

When you run this task it will start the watcher and wait for file changes, just go editing your files, and it will regenerate them as you change files.

You may also use an existing configuration, while still having a different task name:

Smartgen::WatcherRakeTask.new :watcher, :generate_doc do |config|
  config.src_files = ['doc/**/*']
  config.output_folder = 'public/doc'
end

This will use Smartgen config, but you will call it with:

rake watcher
