Hi all,
I’m playing with patterns:
irb(main):001:0> name = “Jasmine”
=> “Jasmine”
irb(main):002:0> phrase = “ja”
=> “ja”
irb(main):003:0> name.sub(/ja/i, ‘**’)
=> "smine"
irb(main):004:0> name.sub(/phrase/i, '’)
=> “Jasmine”
So, how do I tell sub that it should use the local variable phrase
instead of the string ‘phrase’ ?
TIA,
Vamsee.
irb(main):001:0> a = “Jasmine”
=> “Jasmine”
irb(main):002:0> phrase = “jas”
=> “jas”
irb(main):003:0> a.sub(/#{phrase}/i, ‘**’)
=> “**mine”
irb(main):004:0>

Just the same way you do variable substitution in strings (like in
puts):
irb(main):005:0> name.sub(/#{phrase}/i, ‘**’)
=> “**smine”

Try name.sub(/#{phrase}/i, ‘**’)
