Re: Help using self-made but very simple Module

Add use Exporter; at the top of your module. I.e. (simplified):

# your module ScriptUpdate.pm

package ScriptUpdate; 

use Exporter;
our @ISA     = qw(Exporter);
our @EXPORT  = qw(script_stats);

sub script_stats {
    print "script_stats(): ...\n";
}
1;


# the main program:

#!/usr/bin/perl

use lib "./Modules";
use ScriptUpdate;

script_stats();
[download]

Note that our @ISA = qw(Exporter); does not load Exporter.

(Alternatively, add strictures... which will indirectly have the same effect, i.e. loading Exporter as a side effect under the hood... :)

Got me farther, had 2 more error messages pop up, fixed them and now stuck on this one. Can't call method "mtime" without a package or object reference at Modules/ScriptUpdate.pm line 2 This works if i use it as a sub_routine. I added the File::stat lib but still get the error. Here the code that line references. `my $mtime = stat($filename)->mtime;` [download] This is in the package. Do I need to bless something? Reading up on bless now but that's all new to me.

You'd need to `use File::stat` in the package, as by-name stat fields are not core Perl syntax. Alternatively, simply write `(stat $filename)[9]`.	[reply] [d/l] [select]
