Re: how to create a constant file and use it in other file

Referring to $MyConst::const1 works for me:

use strict;
use warnings;
use MyConst;

print $MyConst::const1, "\n"; # prints 1

sorry i just forget that i put "use strict;" in "MyConst.pm" file, without that line, it works; with that line, i got the compile error.	[reply]

Then just add: `our $const1;` [download] to `MyConst.pm` (just before the `Readonly` declaration.) Update: To use a variable in another package without requiring a prefix, you would have to import the symbol from the other package. The standard way to do this is to have `MyConst` be a subclass of Exporter.	[reply] [d/l] [select]

is there a way to export all constants instead of listing each one of them? and also a way to importing all of in another file?	[reply]

oh, i am using perl v5.6.1 can you use the constant data without prefixing it with the package name? ( $const1 instead of $MyConst::const1 )	[reply]
