in reply to Too much Hash??

It looks like $SubOption is being treated as a Hash reference.

No, but $Config{$Item} is. You're printing the values of the %Config hash, which are either hashrefs (in the case of sections with foo=bar lines) or scalars (in other cases). Nothing to be surprised at.

BTW, you'll be running into trouble when you have stanzas in your ini file which contain multiple lines without = in them (e.g. multiple email addresses in [Notify]). You might want to consider changing your data structure.

    Nothing to be surprised at.

    Well, it obviously suprised me. Thanks for telling me that this is normal behaviour, and I've done something stupid.

    Is that a syntax screw-up on my part then?? In my perl books, the closest syntax I can find is $hash{$key}{'string'} = $value, and that's pretty much what I've always used. I thought maybe the backslashes in the path were what was causing it. I've tried puting quotes around the vars (both single and double), escaping said quotes, and a few different syntaxes using the -> and => operators, etc.... I'm talking desperation stuff.

    Could someone at least point me to something that will give my desperation some focus??

    Here is an old write-up of mine that uses the same $MAIN::PageInfo{$section}{$pnum} = $_; style of putting things into a hash....

    Is this much like the last write-up where something is falling out of scope?


    From perldsc -

    # reading from file # flintstones: lead=fred pal=barney wife=wilma pet=dino while ( <> ) { next unless s/^(.*?):\s*//; $who = $1; for $field ( split ) { ($key, $value) = split /=/, $field; $HoH{$who}{$key} = $value; }

    That looks like roughly what I have, without the variables localized. I see I initialize $SubOption at the split, but even with that moved to the top of the sub it still fails.

      What do you mean by "fails?" It would be helpful if you showed us what your expected output is and where the actual output differs. To me it looks like your code is working just fine. To get a better sense of what's actually going on, you might try replacing

      foreach my $value (values %data){ print "$value\n"; }

      with something more like

      foreach my $value (values %data) { if (ref $value ne "HASH") { print "$value\n"; } else { print "$_\n" foreach values %$value; } }

      The point being, that when creating your main hash, some of your values are strings, others are hash references. That's the way your code is designed, so you'll need to change your handling routines to accomodate it.
