Class Method Details

.casecmp?(str0, str1) ⇒ Boolean

Case-insensitive comparison of str0 to str1, returns true or false. Either argument can be nil, where nil compares not equal to anything other than nil.

This is available both as a module function:

Vpim::Methods.casecmp?("yes", "YES")

and an instance method:

include Vpim::Methods
casecmp?("yes", "YES")

Will work with ruby1.6 and ruby 1.8.

TODO - could make this be more efficient, but I’m supporting 1.6, not optimizing for it.

Returns:

  • (Boolean)
