This is a Ruby tree! It shows every object from the Ruby Programming Language in a tree format.
# String.ljust (from ruby core) --- str.ljust(integer, padstr=' ') -> new_str --- If *integer* is greater than the length of *str*, returns a new String of length *integer* with *str* left justified and padded with *padstr*; otherwise, returns *str*. "hello".ljust(4) #=> "hello" "hello".ljust(20) #=> "hello " "hello".ljust(20, '1234') #=> "hello123412341234123"
