As another poster mentioned, you can use
%INC and
File::Basename to identify the filesystem path where acme.pm was found:
use File::Basename 'dirname';
sub get_config {
my $filename = dirname($INC{'acme.pm'}) . "/$_[0]";
croak "Can't find $filename" unless -f $filename;
...
}
Another option is to simply walk
@INC, or some other "config file path" of your choice and find this file:
sub find_config {
my $filename = shift;
foreach (@_) {
return "$_/$filename" if -f "$_/$filename";
}
return;
}
my $filename = find_config("acme.conf", @INC, "/also/search/here", "/a
+nd/here")
or die "Couldn't find acme.conf!";
