Re: How do I access an array in a Module?

Oh I want this ...

use constant EXTHDS => qw(
        "/media/disk"
        "/media/disk-1"
        "/media/disk-2"
        "/media/disk-3"
        "/media/disk-4"
        "/media/disk-5"
);

instead of declaring the array @EXTHDS. I guess.

You almost surely do not want that. `qw//` splits its arguments on whitespace, so you will get an array whose `0`th item is `"/media/disk"`, not `/media/disk`. You can use `qw//` without the quotes, or drop `qw//` and insert commas to just construct a list directly, to get what you probably expect. UPDATE: On further thought, notice that `constant`s are functions, not scalars or arrays (which is why you can't interpolate them). Thus, while you can probably export them using `Exporter`, it's a function (hence must be exported as a bareword, or with preceding `&`), not an array, that you'll be exporting. As others have mentioned, it's probably more straightforward just to make it a package variable (with `our`) so that you can export it directly.	[reply] [d/l] [select]
