String#chop

chop → new_string

static VALUE
rb_str_chop(VALUE str)
{
    return rb_str_subseq(str, 0, chopped_length(str));
}

Returns a new string copied from self, with trailing characters possibly removed.

Removes "\r\n" if those are the last two characters.

Example

"abc\r\n".chop      # => "abc"
"тест\r\n".chop     # => "тест"
"こんにちは\r\n".chop # => "こんにちは"

Otherwise removes the last character if it exists.

Example

'abcd'.chop     # => "abc"
'тест'.chop     # => "тес"
'こんにちは'.chop # => "こんにち"
''.chop         # => ""

If you only need to remove the newline separator at the end of the string, String#chomp is a better alternative.
