Define a configuration file as a Perl package, containing hash data:
$ cat data
package d;
$a = {
1 => 2,
b => 'c',
};
Use this method to read the data straight into Perl:
$ perl -MData::Dumper -le'eval { require "./data"; }; print Dumper($d::a)'
$VAR1 = {
'1' => 2,
'b' => 'c'
};
This avoids the need to employ a parser, as the data is already in a Perl data structure format.
NOTE: You must specify the absolute path to the data file. I found that 'data' failed, where './data' succeeded.
If you leave out the package declaration in the data file, you can access the hash using $main::a
