in reply to Checking value of an extracted variable

r.biswas:

I'd suggest writing a subroutine to read all your configurations into an array, and then when processing the input file you can simply load the current configuration. Something like:

my @configurations; load_configurations("config_file"); open my $FH, '<', $input_fname or die "Can't open $input_fname: $!"; while (<$FH>) { my @config_vars; ... parse out an input entry ... @config_vars = @$configurations[$configuration_ID]; ... code to process input using configuration variables... } sub load_configurations { my $fname = shift; open my $FH, '<', $fname or die "Can't open $fname: $!"; while (<$FH>) { my @config_vars; ... parse out a configuration... $configurations[$configuration_ID] = [ @config_vars ]; } }

This way, you have all the configurations at your fingertips, and you can process each input entry with a different configuration, if desired.

[Discipulus]: if you have a jpeg data: or as wise Corion said IM ca n read directly your handle
[Corion]: Meh. I get the feeling I should post a call-to-action for people to test their modules with the upcoming 5.26 (or 5.25.latest), as it seems that the smoke testers don't really weed out modules that fail without . in @INC
[Corion]: But without instructions on how to easily test things yourself, I don't think such a call to arms is helpful
[Corion]: (this post on nntp.perl.org / p5p makes it seem to me that smoke testers seem to have a blind spot there)
