Hi,
I am starting to play with output ranges and have trouble understanding
how they do work on arrays. Consider the following code :
import std.array;
import std.range;
import std.stdio;
void main(string[] argv)
{
auto a = [1, 2, 3];
a.put(4);
writefln("%s", a);
}
One could expect the call to put() to append 4 to the array so the array
content would be [1, 2, 3, 4].
Instead of this, I get "[2, 3]" to be printed. So I guess put() is
translated to
r.front = e; r.popFront();
as written in std.range.put documentation.
Is it the expected behaviour or is it a bug ?
Expected. If you want an appendable array as an output range, use
std.array.Appender.
auto a = appender([1,2,3]);
a.put(4);
writefln("%s", a.data);
