How to compare strings ignoring the case

I want apple and Apple comparison to be true. Currently

"Apple" == "Apple"  # returns TRUE
"Apple" == "APPLE"  # returns FALSE
Solution

  • You're looking for casecmp. It returns 0 if two strings are equal, case-insensitively.

    str1.casecmp(str2) == 0

"Apple".casecmp("APPLE") == 0
#=> true

    Alternatively, you can convert both strings to lower case (str.downcase) and compare for equality.
