Hi All,
Request your help, on how to sort a tuple container array, I
have raised the same topic in one of the other thread "Tuple
Array Sorting" and was addressed to use standard array rather
than container array, and i am not able to find any document
or example in the library for the same.
Eg: Program.
import std.algorithm: filter, map, sort;
import std.container.array;
import std.file: SpanMode, dirEntries, isDir ;
import std.stdio: writeln;
import std.typecons: Tuple, tuple;
import std.datetime.systime: SysTime;
void main () {
auto FFs = ["C:\\Temp\\BACKUP", "C:\\Temp\\EXPORT"];
Array!(Tuple!(string, SysTime)) Result;
foreach(d; FFs[]) {
auto dFiles = Array!(Tuple!(string, SysTime))(dirEntries(d,
SpanMode.shallow).filter!(a => a.isDir)
.sort!((a,b) => a.timeCreated > b.timeCreated)
.map!(a => tuple(a.name, a.timeCreated)));
writeln(dFiles[]);
} }

HI All,
As per the message from the below forum I understand that
that we cannot perform a sorting on filtered result a container
array but the same can be performed form the standard array, so
i adjusted the above code as below and getting a different
error than what is discussed in the forum.
Forum:
"https://forum.dlang.org/post/[email protected]";
Program:
void main () {
auto FFs = ["C:\\Temp\\sapnas2\\BACKUP",
"C:\\Temp\\sapnas2\\EXPORT"];
Array!(Tuple!(string, SysTime)) Result;
foreach(d; FFs[]) {
auto dFiles = Array!(Tuple!(string, SysTime))(dirEntries(d,
SpanMode.shallow).filter!(a => a.isDir).map!(a => tuple(a.name,
a.timeCreated)))[]
.sort!((a,b) => a[1] > b[1]);
writeln(dFiles[]);
} }
Error:
Message.d(14): Error: function
Message.main.SortedRange!(RangeT!(Array!(Tuple!(string,
SysTime))), __lambda3).SortedRange.opSlice (uint a, uint b) is

Hi All,
Was able to find a solution and it is working as expected
import std.algorithm: filter, map, sort, each;
import std.container.array;
import std.file: SpanMode, dirEntries, isDir ;
import std.stdio: writeln,writefln;
import std.typecons: Tuple, tuple;
import std.datetime.systime: SysTime;
import std.conv;
void main () {
auto FFs = ["C:\\Temp\\BACKUP", "C:\\Temp\\EXPORT"];
Array!(Tuple!(string, SysTime)) Sorted;
foreach(d; FFs[]) {
auto dFiles = Array!(Tuple!(string, SysTime))(dirEntries(d,
SpanMode.shallow).filter!(a => a.isDir).map!(a => tuple(a.name,
a.timeCreated)));
foreach(i; dFiles[]){ Sorted ~= i; }
Sorted[].sort!((a,b) => a[1] > b[1]).each!(e => writefln!"%-63s
%.20s"(e[0], e[1].to!string));
}
}
