Case-insensitive Array#include?

Question

I want to know what\'s the best way to make the String.include? methods ignore case. Currently I\'m doing the following. Any suggestions? Thanks!

Answer 1

You can use casecmp to do your comparison, ignoring case.

"abcdef".casecmp("abcde")     #=> 1
"aBcDeF".casecmp("abcdef")    #=> 0
"abcdef".casecmp("abcdefg")   #=> -1
"abcdef".casecmp("ABCDEF")    #=> 0
