Augment Raku's IO::Path with a .mode() method to get the file mode

Build Status


use IO::Path::Mode;

my $mode = "some-file".IO.mode;

say $mode.set-user-id ?? 'setuid' !! 'not setuid';

say $mode.user.execute ?? 'executable' !! 'not executable';

say $mode.file-type == IO::Path::Mode::File ?? 'file' !! 'something other than a normal file';



This augments the type IO::Path to provide a .mode method that allows you to get at the file permissions (or mode.) It follows the POSIX model pf user, group and other permissions and consequently may not make a meaningful result on e.g. Windows (although the underlying calls appear to return something approximating the correct answer.)

If you have a more recent rakudo that provides a mode method, it will replace that method with one that returns an IO::Path::Mode object rather than an IntStr, this is a transitional arrangement and will be deprecated in a future release in favour of a different method name.

It relies on some non-specified functionality in the VM so may probably only work with Rakudo on MoarVM.

This is mostly provided as some relief for not having the functionality directly exposed in Rakudo and as a discussion board for the best way of implementing the functionality going forward.


Assuming you have a working Rakudo installation you should be able to install this with zef :

# From the source directory

zef install .

# Remote installation

zef install IO::Path::Mode


I welcome suggestions, patches and bug reports at https://github.com/jonathanstowe/IO-Path-Mode/issues

I'd be particularly interested in suggestions relating to making the mode mutable and adding a multi candidate for 'chmod' that can take an IO::Path::Mode object.
