Hi,
Request your help on the below issue,
Issue : While appending data to a array the data is getting
duplicated.
Program:
import std.file: dirEntries, isFile, SpanMode;
import std.stdio: writeln, writefln;
import std.algorithm: filter, map;
import std.array: array;
import std.typecons: tuple;
string[] Subdata;
void main ()
{
auto dFiles = dirEntries("C:\\Temp\\TEAM",
SpanMode.shallow).filter!(a => a.isFile).map!(a => tuple(a.name
, a.timeCreated)).array;
foreach (d; dFiles)
{
Subdata ~= d[0];
Subdata ~= d[1].toSimpleString;
writeln(Subdata);
}
}
Output:
["C:\\Temp\\TEAM\\test1.pdf", "2017-Aug-24 18:23:00.8946851"]
- duplicate line
["C:\\Temp\\TEAM\\test1.pdf", "2017-Aug-24 18:23:00.8946851",
"C:\\Temp\\\\TEAM\\test5.xlsx", "2017-Aug-25 23:38:14.486421"]

You are consecutively appending to an array in each loop
iteration step, i.e. you are buffering, and you're printing the
current state of the buffer (all previously buffered elements) in
each loop iteration. I can't see any duplication going on, what
exactly to you wish to accomplish?
