Issue #21284 has been updated by nobu (Nobuyoshi Nakada). It may be possible with `Array#fill` and start-exclusive range? ```ruby ary.fill(object, -1^..padding_length) ``` ---------------------------------------- Feature #21284: Request: add `Array#pad` method https://bugs.ruby-lang.org/issues/21284#change-112780 * Author: MatzFan (Brian Cohen) * Status: Open ---------------------------------------- A method to pad an array of arbitrary length with objects up to a specified array size does not currently exist. `Array#fill` does not do this and I therefore propose the following method: ``` ruby class Array def pad(pad_to_length, object = nil) fill(object, size, pad_to_length - size) end end ``` I have provided an [answer](https://stackoverflow.com/a/79591610/4114896) to a Stack Overflow question asking how this can be done in Ruby. I've also explained in a comment on the answer which suggests using `Array#fill` why this does not meet the exact need. -- https://bugs.ruby-lang.org/
