string equivalency

Brad Tilley

8/16/2006 1:42:00 PM

What's the best way to check if a string is not exactly what you're
expecting? I'm doing this:

b = 'brad'
if not b.eql?('bradsdhsh')
puts 'not equal'
else
puts 'equal'
end

Is there a more proper way to do it?

KISS:

b = 'brad'

if 'bradsdhsh' == b
puts 'equal'
else
puts 'not equal'
end

Or, as a one liner

puts 'bradsdhsh' == b ? 'equal' : 'not equal'

This is prefered over the String.eql? method?

I prefer it and it seems most others, too. Looks better - and note that
it's not like in Java where there is a significant difference between ==
and equals().

Kind regards
