In the ruby programming language a distinction is made between loading and
autoloading. For those of you familiar with Rails, this will shed some light on
the change from
config.autoload_paths in Rails 3. The
difference lies in when the class is actually called/initialized.
Let’s say I have defined a SpecialLibrary class:
When I load or require the class, the entire class code is run:
When I autoload the class, the class code is only run when I actually use the class:
config.load_paths was changed to
config.autoload_paths in Rails 3
is because the paths defined here were being auto-loaded and not simply
config.autoload_paths is more descriptive and accurately
describes the behavior.
