String#eql?

(untyped other) -> bool

eql?(object) → true or false

VALUE
rb_str_eql(VALUE str1, VALUE str2)
{
    if (str1 == str2) return Qtrue;
    if (!RB_TYPE_P(str2, T_STRING)) return Qfalse;
    return rb_str_eql_internal(str1, str2);
}

Returns whether self and object have the same length and content:

Example

s = 'foo'
s.eql?('foo')  # => true
s.eql?('food') # => false
s.eql?('FOO')  # => false

Returns false if the two strings’ encodings are not compatible:

Example

s0 = "äöü"                           # => "äöü"
s1 = s0.encode(Encoding::ISO_8859_1) # => "\xE4\xF6\xFC"
s0.encoding                          # => #<Encoding:UTF-8>
s1.encoding                          # => #<Encoding:ISO-8859-1>
s0.eql?(s1)                          # => false
