Re^6: more fun w/ HASh ref's

Try s/\s*$//; instead of your regex. It might not be a literal space - it might be any one of a number of whitespace characters.

Plus, the problem isn't with $val, it's with $key. Try printing out $key in each iteration with single-quotes around it.

My criteria for good software:

Does it work?
Can someone else come in, make a change, and be reasonably certain no bugs were introduced?

Thank you for your time, kind monk. I've tried \s, \S and \ * in string substitutions in an effort to lose that trailing space. I have now intoduced a line which reads: `print STDERR "\|$host\|, \|$db\|, \|$user\|, \|$pw\|";` [download] to determine where that space might be introduced. In Main::, when I define $db as $config{'db_name'}, I get the right value in the log. When I define $db as $config{'db}{'db_name'}, it throws the HASH ref error (as a Fatals to Browser message) and bombs out before it gets to my print STDERR debug statement. As you can see from the code I posted at http://perlmonks.org/?node_id=511957, my supporters_conf.pm module includes a while <DB> block which includes: `my ($key, $val) = split(/\s=\s/,$_,2); $key =~ s/^\s//; $val =~ s/ $//g; # also tried \s* and \S*, as well $config{'db'}{"$key"} = $val; $config{"$key"} = $val;` [download] So I'm thinking this has something to do with the $config{'db'}{'db_name'} piece and not with the value assigned to this hash element. -- Hugh	[reply] [d/l] [select]
