title: butlast Operator
type: text/vnd.tiddlywiki
caption: butlast
op-purpose: discard the last <<.place N>> input titles
op-input: a [[selection of titles|Title Selection]]
op-parameter: an integer, defaulting to 1
op-parameter-name: N
op-output: all but the last <<.place N>> input titles

<<.from-version "5.2.2">> The <<.op butlast>> operator returns the input list unchanged if <<.place N>> is 0. This is consistent with the behaviour of the [[rest Operator]].
