Hello monks,

I frequently replicate others' posts so as to help if I can, learn more of a gigantic language, and have new scripts that will improve my own capabilities. So it is that chungley2000 rolled in with a question that morphed into about how to get values from Config. I've been playing with the values for a couple days now, and I wrote a script to see what output resulted from the 4 method function calls that this module exports. I've commented out failed attempts to herd these values into lexical variables.

#!/usr/bin/perl -w
use 5.011;
use Config qw(myconfig config_sh config_vars config_re);
use Data::Dumper;

say myconfig();
say "---------------";
say config_sh();
say "---------------";
say config_vars();
say "---------------";

my $ref_Env = \%ENV;
say Dumper $ref_Env;
my $version = config_re("version");
say "version is $version";

# my $archname = $Config{'archname'}; #produces error: %Config unknown
say "---------------";
#my $ref_Config = \%CONFIG;
#say Dumper $ref_Config;

Abridged output, where I've commented on values with a double hashmark:

My experience with the large family of Config modules has been with Config::Tiny, where I have imported such values from an .ini file. Now I would like to import the values from the myconfig() method into a hash.

If I had to get values quick and dirty, I would create a temp file with Path::Tiny, then read it with Config::Tiny. But when you have the darn thing in memory already, it seems like a significant work-around, in particular, when you are only going to delete the file for being a security risk. I don't want these data to be persistent beyond the first few lines of a perl script. Other modules from the Config namespace seem promising, but, for example CONFIG::Hash seems like it might be the thing I'm looking for, but not quite. There are at least 12 screens of matches for Config in cpan.

I could also use bash to pipe these values, but do I really need a shell? It seems like there could be a perl-only solution to this, which is more portable. My question then is how to to herd the = joined and newline separated values from

config_vars()

into a hash.

Thank you for your comment,
