AutoReload

Description

Autoreload automatically reloads library files after they have been updated. It is especailly useful when testing stateless services such as web applications.

IMPORTANT! Version 1.0+ has a new API. It also works best under Ruby 1.9 or above. Under Ruby 1.8 or older files are reloaded regardless of whether they actually have changed since the last load. Whereas in Ruby 1.9+, they only reload if the mtime on the file is newer than the previous time.

Synopsis

Say we have a library foo.rb in our load path:

def foo
  1
end

We can then run the following script, example.rb:

require 'autoreload'

autoreload(:interval=>2, :verbose=>true) do
  require 'foo.rb'
end

loop {
  puts foo
  sleep 2
}

With that running we can change foo.rb and the change will take effect in example.rb within two seconds of being made.

Note, that autoreload only works with required files. It cannot monitor files that are broght in with load. This is because $LOADED_FEATURES is used to track which files are monitored.
