Hi H. S. Teoh, I have used you fastcsv on my file:
import std.file;
import fastcsv;
import std.stdio;
import std.datetime;
void main(){
StopWatch sw;
sw.start();
auto input = cast(string) read("Acquisition_2009Q2.txt");
auto mydata = fastcsv.csvToArray!('|')(input);
sw.stop();
double time = sw.peek().msecs;
writeln("Time (s): ", time/1000);
}
$ dmd file_read_5.d fastcsv.d
$ ./file_read_5
Time (s): 0.679
Fastest so far, very nice.
