Re: Config::Simple with vars method

[davidj]

First, Data::Dumper reveals why you are not getting anything returned.

#!/usr/bin/perl -w
use Config::Simple;
use strict;
use Data::Dumper;
my $cfg;
my %config;
$cfg = new Config::Simple('test.cfg');
open(FH,"test.cfg");
printf("'%s' syntax\n", $cfg->guess_syntax(\*FH));
close FH;
%config = $cfg->vars();
print Dumper(\%config);
exit;

D:\PerlProjects\tests>c.pl

output:

'ini' syntax
$VAR1 = {
          'default.NET' => 'X'
        };

Now the reason for it (from a cursory reading of the Config::Simple manpage):
Config::Simple assumes config information is formatted in a block system, such as:

[block1]
key=value

Since your config file does not have any block delimiters (indicated by brackets), the values are assigned to the 'default' block.
changing your config file to the following:

[info]
NET=X

generates the following output:

D:\PerlProjects\tests>c.pl
'ini' syntax
$VAR1 = {
          'info.NET' => 'X'
        };

I would suggest you perldoc Config::Simple to learn more about the module.

hope this helps,

David,
I follow your info, but the CPAN page says: Quote
Return value is one of "ini", "simple" or "http".
Unquote
when mentioning the 'guess_syntax' method. As my file is simple, it should recognise it as such.
It also shows what code to use for 'simple' and 'ini' style files: Quote


  my %Config = $cfg->vars();
  print "Username: $Config{User}";

  # If it was a traditional ini-file:
  print "Username: $Config{'mysql.user'}";

where the first is for 'simple' files, which I want to use.
Cheers

Chris,
I think you need to read the documentation a little more closely. It reads:

SIMPLE CONFIGURATION FILE

"Simple syntax is what you need for most of your projects. These are, as the name asserts, the simplest. File consists of key/value pairs, delimited by nothing but white space."

INI-FILE

"These configuration files are more native to Win32 systems. Data is organized in blocks. Each key/value pair is delimited with an equal (=) sign. Blocks are declared on their own lines enclosed in (brackets):"

Your not providing blocks does not make it a 'simple' file. The fact that you are using '=' as a key/value delimiter does make it an 'ini' file. If you want to use 'simple', the replace the '=' with whitespace.
