You changed the type of dFiles, which you return from
cleanFiles, without changing the return type of cleanFiles.
Change the return type of cleanFiles to the type the compiler
error above tells you it should be (`Tuple!(string,
string)[]` instead of `string[][]`), or let the compiler
infer it via auto (`auto cleanFiles(...`).
Hi,
Thank you very much, was able to resolve the second code
issue by changing the return type of the function.
Hi,
In order to resolve the issue "Using closure causes GC
allocation" it was stated that we need to use delegates, can
you please help me on how to as i have not gone that much far
in D programming.
import std.stdio: File,writeln;
import std.datetime.systime: Clock, days, SysTime;
import std.file: SpanMode, dirEntries, exists, isFile, mkdir,
remove;
import std.typecons: tuple, Tuple;
import std.algorithm: filter, map, each;
import std.array: array;
Tuple!(string)[] logClean (string[] Lglst, int LogAge) {
if (!Lglst[0].exists) { mkdir(Lglst[0]); }
auto ct1 = Clock.currTime();
auto st1 = ct1 + days(-LogAge);
auto dFiles = dirEntries(Lglst[0], SpanMode.shallow).filter!(a
=> a.exists && a.isFile && a.timeCreated < st1).map!(a =>
tuple(a.name)).array;
dFiles.each!(a => a[0].remove);
return dFiles;
}
void main () {
string[] LogDir =
["C:\\Users\\bheev1\\Desktop\\Current\\Script\\D\\Logs"];
int LogAge = 1;
logClean(LogDir,LogAge);
}

If you are getting Using closure causes GC allocation from the
above, it will be because you reference a local in the template
delegate argument to filter:
filter!(a => a.exists &&
a.isFile &&
a.timeCreated < st1)
^^^
because of the local (st1) it needs a closure. I can't remember
how to transform delegates to take parameters and then call with
the parameter set to the local, someone else will have to fill
you in on that one.
