digitalmars.D.learn - Container Array or tuples Sorting
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[]); } } From, Vino.B
