HI Experts,
i need to know the difference between %{} and #{}
waiting for the response
regards,
Bala
first of all, i don’t really think u’d be using %{} too much of the time
(you might use some of the options available, like %q{} which is like
single quotes, and %Q{} which is like double-quotes.
basically:
%{} -> turns the stuff written into a string.
#{} -> if inside double quotes, eval the code inside.
hope the following example helps out a bit more:
shai@meshi:~/ruby$ cat str.rb
#!/usr/bin/ruby
one=1
two=2
puts “the variable ‘one’ used with #{} is #{one}”
puts “this is one with %{} in a string: %{one}”
puts “this is one with %{} ruby (not within a string):” + %{one}
puts “”; puts “notice something else though:”; puts “”
puts “this is two with ruby and %q{}:” + %q{#{two}}
puts “this is two with ruby and %Q{}:” + %Q{#{two}}
shai@meshi:~/ruby$ ruby str.rb
the variable ‘one’ used with #{} is 1
this is one with %{} in a string: %{one}
this is one with %{} ruby (not within a string):one
notice something else though:
this is two with ruby and %q{}:#{two}
this is two with ruby and %Q{}:2
