Class Camping::Reloader
In: lib/camping/reloader.rb
Parent: Object

The Camping Reloader

Camping apps are generally small and predictable. Many Camping apps are contained within a single file. Larger apps are split into a handful of other Ruby libraries within the same directory.

Since Camping apps (and their dependencies) are loaded with Ruby‘s require method, there is a record of them in $LOADED_FEATURES. Which leaves a perfect space for this class to manage auto-reloading an app if any of its immediate dependencies changes.

Wrapping Your Apps

Since bin/camping and the Camping::Server class already use the Reloader, you probably don‘t need to hack it on your own. But, if you‘re rolling your own situation, here‘s how.

Rather than this:

  require 'yourapp'

Use this:

  require 'camping/reloader'
  reloader = Camping::Reloader.new('/path/to/yourapp.rb')
  blog = reloader.apps[:Blog]
  wiki = reloader.apps[:Wiki]

The blog and wiki objects will behave exactly like your Blog and Wiki, but they will update themselves if yourapp.rb changes.

You can also give Reloader more than one script.
