April 30, 2011 What is put() useful for with regards to dynamic arrays? | ||||
---|---|---|---|---|
| ||||
import std.range; void main() { int[] a = [1, 2, 3]; a.put(6); assert(a == [2, 3]); a.put([1, 2]); assert(a.length == 0); } Seems kind of odd.. put is implemented as an append method for some custom types, e.g. std.array.appender. But for arrays put just removes Item or RangeLength number of elements from the array. What's the use case for this? |

This should probably be in a FAQ somewhere. :) http://www.digitalmars.com/d/archives/digitalmars/D/ std.array.put_doesn_t_put_106871.html -Lars |

Posted in reply to Lars T. Kyllingstad | Thanks, that post explained it. Obviously I wasn't the first and likely won't be the last person to run into this. Maybe put's documentation could make a note of this. |
