perl config parser
Hello.
Can anybody help me with some sub on perl that can parse config like this:
Code:
%CFG (
   'databases' => {
      'db1' => 'db_11', 'db_12', 'db_13',
      'db2' => 'db_21', 'db_22', 'db_23'
   }
   'datafiles' => {
      'datadir1' => 'datadir_11', 'datadir_12',
      'datadir2' => 'datadir_21', 'datadir_22'
   }
   log => {
      'logfile' => '/var/log/logfile'
      'loglevel' => 'warn'
   }
)




It should something like hash of hashes, but the following code but I don't know how to parse multiple values of db1...
Does anybody know how to change it to be accessed like $CFG::CFG{'databases'}{'db1'}

not quiet sure about your concern, but below should work

Code:
$CFG->{databases}->{db1}

If you want a simple way to read a file to such a structure, use YAML, eg via Config::YAML. If it's something else you want, please be more clear and complete on your explanation.

The code you posted is not valid perl code. Do you need to know how to write the code to make a hash of hashes or hash of arrays or what?

Seems I was not clear in my question. I just need some structured config with multiply values for key. (You see in config 'db2' => 'db_11', 'db_12', that is not valid. Valid only 'db2' => 'db_11'). seems YAML is way I should going through.
