Raised when the tree is malformed or there is a bug in the compiler.
Returns a 3-element array of substrings of self
.
Matches a pattern against self
, scanning backwards from the end. The pattern is:
string_or_regexp
itself, if it is a Regexp
.
Regexp.quote(string_or_regexp)
, if string_or_regexp
is a string.
If the pattern is matched, returns pre-match, last-match, post-match:
'hello'.rpartition('l') # => ["hel", "l", "o"] 'hello'.rpartition('ll') # => ["he", "ll", "o"] 'hello'.rpartition('h') # => ["", "h", "ello"] 'hello'.rpartition('o') # => ["hell", "o", ""] 'hello'.rpartition(/l+/) # => ["hel", "l", "o"] 'hello'.rpartition('') # => ["hello", "", ""] 'тест'.rpartition('т') # => ["тес", "т", ""] 'こんにちは'.rpartition('に') # => ["こん", "に", "ちは"]
If the pattern is not matched, returns two empty strings and a copy of self
:
'hello'.rpartition('x') # => ["", "", "hello"]
