This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# String.rpartition (from ruby core) --- str.rpartition(sep) -> [head, sep, tail] str.rpartition(regexp) -> [head, match, tail] --- Searches *sep* or pattern (*regexp*) in the string from the end of the string, and returns the part before it, the match, and the part after it. If it is not found, returns two empty strings and *str*. "hello".rpartition("l") #=> ["hel", "l", "o"] "hello".rpartition("x") #=> ["", "", "hello"] "hello".rpartition(/.l/) #=> ["he", "ll", "o"] The match from the end means starting at the possible last position, not the last of longest matches. "hello".rpartition(/l+/) #=> ["hel", "l", "o"] To partition at the last longest match, needs to combine with negative lookbehind. "hello".rpartition(/(?<!l)l+/) #=> ["he", "ll", "o"] Or String#partition with negative lookforward. "hello".partition(/l+(?!.*l)/) #=> ["he", "ll", "o"]
