simple gsub method

Jack Smith

10/1/2008 8:42:00 PM

I have simplified my method for searching test to the following:

def replacer(a, b)
x = "now is the time for all good men to come to the aid of their
country"
x.gsub(/#{a}/, b)
puts x
end

puts "enter what to replace: "
j = gets
puts "enter replacer word: "
h = gets

replacer(j, h)

Can someone help me determine why gsub can't match my "a" value?

thanks

Strings returned by gets end in a newline, which doesn't exist in your string,
so no match happens. To solve this, you can do

j = gets.chomp

and the same for h.

I hope this helps

It does help Stefano as I had forgotton about \n so thanks for that but
my script still does not match on my "a" value even with the chomp
method added.

You don't use the return value of gsub, so it is thrown away and this line
basically does nothing. Calling gsub on x, does not change x (gsub! would).

Yes, the GOP is the party of the rich. You would be a fool to vote for a
Republican. Are you as much of a fool as you present yourself to be
here?

Tiller should not have been murdered. However, I did not shed any tears
when I found out that Tiller the baby killer was dead.

The social services department can handle those unwanted babies and help
to get them adopted.

More proof that you are a horrible person. Why do you display that so

What is funny (well, actually sad) is that social services that Jason
says will handle the unwanted children are precisely the things that his
Republican heroes want to cut. Go figure...
