“foo”.blarg
NoMethodError: undefined method `blarg’ for “foo”:String
from (irb):6
from :0

class String
def blarg
“blarg”
end
end
=> nil

“foo”.blarg
=> “blarg”

Ahh, I understand your question.

I have a private plugin I made for this sort of thing. Just look up
how to make a very simple plug-in, and you’ll be set. If you do that,
you can also maintain it and use it easily in other projects.

thanks works great, here is a nice tuto to create its own plugins :

I’d place it in an initializer.

I place the following in MyApp/lib/time_extensions.rb

class Time
def beginning_of_hour
self-(self.min).minutes-self.sec
end
def end_of_hour
self.beginning_of_hour + 1.hour - 1.second
end
def beginning_of_minute
self-self.sec
end
def end_of_minute
self.beginning_of_minute + 1.minute - 1.second
end
def beginning_of(secs=5.minutes)
return self if secs >= 1.day/2
secs_today = self - self.beginning_of_day
periods_today = (secs_today/secs).floor
self.beginning_of_day + periods_today * secs
end
def end_of(secs=5.minutes)
return self if secs >= 1.day/2
beginning_of(secs) + secs - 1.second
end
end
