Greetings all,

I need to walk up the directory tree from where I am until I find a directory containing a certain marker file. (This is to locate the base directory of an installation, which is then used to add the project's /lib to @INC.)

Is there anything more elegant than this? 

use strict; use warnings;
use Path::Tiny;

sub find_base { -f "$_[0]/.marker" ? $_[0] : find_base($_[0]->parent) 
+}
my $base = find_base( path(__FILE__)->realpath->parent );
unshift @INC, "$base/lib";

use Some::Class;
...

(I am aware that this does not handle the file not being found.)

Thanks for any suggestions!


The way forward always starts with a minimal test.
