There are some ways to 'source' a config file like under unix shell.
Just show 3 ways below:
#########################
# the first way
#########################
The first,you can just require a file,because this file didn't be
declared as a package,so it doesn't has its own namespace,so all
variables in this file can be imported into main package's space.
$ cat mydata.pl
use strict;
our (@key1,@key2);
$key1[64]="0xc120718a1ccce7f8";
$key2[64]="0xeadf28cb82020921";
$key1[128]="0xaf503224b6cff0639cf0dc310a4b1277";
$key2[128]="0x3e1fcbd4e91ca24bb276914de3764cdf";
1;
$ cat usedata.pl
require 'mydata.pl';
print $key1[64];
#########################
# the second way
#########################
The second way,you can declare the config file as a package,and export
the needed varibles.When main script use this package,it import those
variables automatically.
$ cat mydata2.pm
package mydata2;
use strict;
require Exporter;
our @ISA = qw(Exporter);
our (@key1,@key2);
our @EXPORT = qw(@key1 @key2);
$key1[64]="0xc120718a1ccce7f8";
$key2[64]="0xeadf28cb82020921";
$key1[128]="0xaf503224b6cff0639cf0dc310a4b1277";
$key2[128]="0x3e1fcbd4e91ca24bb276914de3764cdf";
1;
$ cat usedata2.pl
use mydata2;
print $key1[64];
#########################
# the third way
#########################
Both the first way and the second way are not good.Because your config
file is large,the former ways have imported all those large content
into your main script.If your main script is run under cgi/modperl
which is generally multi-process,your memory could be eated quickly.So
the best way is to create an object then multi-process can share this
object,since object is only located in its own namespace.
$ cat mydata3.pm
package mydata3;
use strict;
sub new {
my $class = shift;
my (@key1,@key2);
$key1[64]="0xc120718a1ccce7f8";
$key2[64]="0xeadf28cb82020921";
$key1[128]="0xaf503224b6cff0639cf0dc310a4b1277";
$key2[128]="0x3e1fcbd4e91ca24bb276914de3764cdf";
bless {key1=>[EMAIL PROTECTED],key2=>[EMAIL PROTECTED],$class;
}
1;
$ cat usedata3.pl
use mydata3;
my $d = mydata3->new;
print $d->{key1}->[64];
Good luck with it!
