Module: Reloadable

Defined in:
lib/reloadable.rb

Overview

Reloadable simply makes it possible for a module’s code to be reloaded. Important: Only code loaded via Autoload or Autocreate will be reloaded. Also, the module itself is not reloaded, only the modules and classes within it that were loaded via Autocode.

To use Reloadable, simply extend a given module with Reloadable. This will add two methods to the module: reloadable and reload. These are described below.

	mod.metaclass.class_eval do
		
		# Returns the list of constants that would be reloaded upon a call to reload.
		def reloadable( *names ) 
			( @reloadable ||= [] ).concat(names)
			return self
		end
		
		# Reloads all the constants that were loaded via *Autocode*. Technically, all reload is doing is undefining them (by calling +remove_const+ on each in turn); they won't get reloaded until they are referenced.
		def reload
			( @reloadable ||=[] ).each { |name| remove_const( name ) }
			@reloadable = []; return self
