Module: SmartInit

Included in:
Object
Defined in:
lib/drumherum/smart_init.rb

Overview

smart_init finds the directory named ‘lib’ in your project and adds

  • the (main) directory above

  • the lib-directory itself

to Rubys $LOAD_PATH. So your require statements load the actual version from your (local) project directory, not the (public) gem version.

Also, smart_init sets some release infos for Hoe.

Usage (wherever you are in the directory hierarchy of your project):

if $0 == __FILE__ 
  require 'drumherum'
  smart_init 
end
require 'my-gem-project'   # actual local version, not the gem version

Included in Object collapse
