Using ice_cube Ruby gem in IRB
سؤال
I'm trying to use a Ruby gem called ice_cube in IRB, but it doesn't work:
[~]$ rvm gemset create ice
'ice' gemset created (/home/joe/.rvm/gems/ruby-1.9.2-p320@ice).
[~]$ rvm gemset use ice
Using ruby-1.9.2-p320 with gemset ice
[~]$ gem install ice_cube
Fetching: ice_cube-0.8.0.gem (100%)
Successfully installed ice_cube-0.8.0
1 gem installed
Installing ri documentation for ice_cube-0.8.0...

[~]$ irb --simple-prompt
>> require 'ice_cube'
=> true
>> schedule = Schedule.new(Time.now)
NameError: uninitialized constant Object::Schedule
from (irb):2
from /home/joe/.rvm/rubies/ruby-1.9.2-p320/bin/irb:16:in `<main>'
What am I doing wrong? (I'm a beginner Ruby programmer.)
المحلول
It should be:
schedule = IceCube::Schedule.new(Time.now)

include IceCube
schedule = Schedule.new(Time.now)
Or you can first include the module into global namespace, then you can use whatever it is in that module.
