      i just want to be able to store these values in a csv format, so i can render it in a graph.

Rendering an array of data into a CSV row is fairly simple. Here's one example:

#!/usr/bin/perl use strict; my $data = [ [ qw/ a b c d /], [ qw/ e f g h /], [ qw/ i j k l /] ]; my $outfile = "/path/to/my/file.csv"; open FOUT,"> $outfile" or die "$outfile: $!"; foreach my $row (@$data){ printf FOUT "%s\n',join(",",@$row); } close FOUT;
There are many many other ways of doing this but there is one way.

[1nickt]: choroba Understood. I'm wondering about the logic in a cpanfile. If the perl doesn't support threads, it's easy: require MCE. If the perl does support threads, as you say the user has a choice, so require both? Or, assume that irrespective of the choide
[1nickt]: ... choice, the threaded-perl user *probably* wants to use threads, therefore only require threads and leave MCE out, allowing the user to manually install if desired?
[choroba]: just require any of MCE and threads. Not sure if that's possible in the cpanfile, but should be possible early in the Makefile
[1nickt]: The app expects threads as default anyway, right?
[choroba]: that's true
[1nickt]: expects threads *to be* the default
[1nickt]: I think cpanfile can handle the logic. testing now.
