Re^2: more fun w/ HASh ref's

Jarich:

Thank you sir, for those leads.

I've been running tests with Config::IniHash. Its working on every part of my barely edited config files, except for the heredoc variables in my supporters.copy.ini file.

But now I'm getting this error:

Wed Nov 30 16:41:47 2005 error client 24.67.197.93 Can't use an undefinedvalue as a HASH reference at /usr/lib/cgi-bin/bc/test.pl line 24.

line 24 reads:

my $options->{'heredoc'} = '1';

I know someone here the other day was telling me I should not quote my hash keys, but on my installation it does not seem to work unless I do.

#!/usr/bin/perl
use strict;
# use supporters_conf qw(%config);
use Config::IniHash;

# $hashreference = ReadINI ($filename, %options);

use CGI;
use CGI::Pretty qw(:all *table param);

my $url = url();
# my $table1 = fqtn(@config{qw(db prefix)},"basetablename");
my $conf = parse_config_directory($url);
my $path = $0;
my $script = $0;
$script =~ s/^(.*)\///;
# $conf =~ s/$script//;
# $path =~ s/$script/conf.d\/$conf\/supporters.conf/;
my $config_conf = ReadINI ($conf);

my $copy = $conf;
$copy =~ s/\.conf/.copy/;
my %options;
my $options->{'heredoc'} = '1';
my $config_copy = ReadINI ($copy,%options);

my $db = $conf;
$db =~ s/\.conf/.db/;
my $config_db = ReadINI ($db);

print header("Testing parser for configuration files"),
  start_html("Testing parser for configuration files"),
  p("And the question of the hour is:  Will the config module export t
+he form copy.  This experiment shall tell us."),
  p("Script path and name is: ".$0),
  p("Script name is: ".$script),
#  p("Scriptpath: ".$sp),
#  p("Scriptname: ".$sn),
  p("Path to configuration files at: <b>".$conf."</b>"),
  p("Script accessible at: ".$url),
#  p("Fully Qualified Table Name looks like: ".$table1),
  p("Config::IniHash says \$config = ".$config_conf."."),
  p("And the mail-abuse address is: ".$config_conf->{'mail-server'}->{

  p("The database name is: ".$config_db->{'db'}->{'db_name'}."."),
  p("The donor form disclaimer reads: <br>".$config_copy->{'copy'}->{'
+donor_form_disclaimer_copy'}."."),
  p(),p(),
  $supporters_conf::config{'donor_thanks'},
end_html();

exit;
sub parse_config_directory() {
  my($conf)=@_;
  # call as follows
  # use CGI;
  # $url = url();
  # $conf = parse_config_directory($url);
  my $scriptpath = $0;
  my $scriptname = $0;

  $conf =~ s/\//./g;
  $conf =~ s/\.$scriptname//;
  $conf = $scriptpath."conf.d/".$conf."/supporters.conf.ini";
  return $conf;
  # configuration file, ready for execution
} # END parse_url

sub fqtn(){
  my($db,$prefix,$table)=@_;
  $db =~ s/ *$//;
  $prefix =~ s/ *$//;
  $table =~ s/ *$//;
  my $fullyqualifiedtablename = $db.".".$prefix.$table;
  return $fullyqualifiedtablename;
} #     END fqtn

Any ideas how I might work through this one? I've written this multiple ways and keep getting one error or another.

my %options;
my $options->{'heredoc'} = '1';
my $config_copy = ReadINI ($copy,%options);

What this is actually saying is annotated below.

# Create a hash called %options
my %options;

# Create a *scalar* variable called $options and then try
# to use it as a reference.  Since it's just been created, 
# it's undefined.  Hence this won't work.
my $options->{'heredoc'} = '1';

# Call ReadINI passing it $copy and  your %options hash.
my $config_copy = ReadINI ($copy,%options);

I imagine that the line you want to have in the middle there is:

$options{heredoc} = 1;
[download]

It's a hash look up. %options is a hash, not a hash reference. If its not a reference, you don't want the arrow.

I hope this helps.
