How to take N last of elements of range?
I have tried the following example in my code, but it says that
it deprecated. What is the other possible way?
static struct LogerInfo
{
string func;
int line;
void write(T...)(T data)
{
import std.stdio;
import std.algorithm: splitter;
import std.range: retro;
import std.range: take;
import std.array: array;
string shortFuncName =
func.splitter(".").retro.take(2).retro.array;
writeln( shortFuncName, "[", line, "]: ", data );
}
}
It says the following:
/usr/include/dmd/phobos/std/range/package.d(224): Deprecation:
function std.algorithm.iteration.splitter!("a == b", string,
string).splitter.Result.popBack is deprecated - splitter!(Range,
Range) cannot be iterated backwards (due to separator overlap).
/usr/include/dmd/phobos/std/range/package.d(223): Deprecation:

string).splitter.Result.back is deprecated - splitter!(Range,
