Re: using perl references from subroutine

[Noah]

simple - that did it.  of course I removed the "my" when defining 
$templateConfiguation in the for loop.

thanks!

Hi Noah,

Would defining $templateConfiguration outside of the for loop be 
sufficient for what you need?

i.e.,

my $templateConfiguation;
foreach my $templateConfigFilename (@templateConfigFilenames) {
   $templateConfigFilename = "$TemplateDirectory/$templateConfigFilename";
   (my $sortedTemplateConfigFilename = $templateConfigFilename) =~ 
s/.(configuration.txt)/.sorted-$1/;
   push (my @sortedTemplateConfigFilenames, $sortedTemplateConfigFilename);

   # go read template files and save as sorted
   $templateConfiguation = &readConfigTemplate($templateConfigFilename, 
$sortedTemplateConfigFilename);
}


You probably should give it some initial value or do some checking just 
in case nothing is assigned to it within the for-loop...

Okay I see why $templateConfiguration is defined inside a for loop.  
how can I make sure the referenced hash that is returned inside the 
for loop is passed to the main portion of the program.

Here is the for loop.

--- snip ---

foreach my $templateConfigFilename (@templateConfigFilenames) {
    $templateConfigFilename = 
"$TemplateDirectory/$templateConfigFilename";
    (my $sortedTemplateConfigFilename = $templateConfigFilename) =~ 
s/.(configuration.txt)/.sorted-$1/;
    push (my @sortedTemplateConfigFilenames, 
$sortedTemplateConfigFilename);

    # go read template files and save as sorted
    my $templateConfiguation = 
&readConfigTemplate($templateConfigFilename, 
$sortedTemplateConfigFilename);
}
