Path::FindDev(3) User Contributed Perl Documentation Path::FindDev(3)

Path::FindDev - Find a development path somewhere in an upper hierarchy.

version v0.5.3

This package is mostly a glue layer around "Path::IsDev" with a few directory walking tricks.

use Path::FindDev qw( find_dev );
if ( my $root = find_dev('/some/path/to/something/somewhere')) {
    print "development root = $root";
} else {
    print "No development root :(";
}

my $result = find_dev('/some/path');

If a "dev" directory is found at, or above, "/some/path", it will be returned as a "Path::Tiny"

If you pass configurations to import:

use Path::FindDev find_dev => { set => $someset };

Then the exported "find_dev" will pass that set name to "Path::IsDev".

Though you should only do this if

  • the default set is inadequate for your usage
  • you don't want the set to be overridden by %ENV

Additionally, you can call find_dev directly:

require Path::FindDev;
my $result = Path::FindDev::find_dev('/some/path');

Which by design inhibits your capacity to specify an alternative set in code.

Have you ever found yourself doing

use FindBin;
use lib "$FindBin::Bin/../../../tlib"

In a test?

Have you found yourself paranoid of file-system semantics and tried

use FindBin;
use Path::Tiny qw(path)
use lib path($FindBin::Bin)->parent->parent->parent->child('tlib')->stringify;

Have you ever done either of the above in a test, only to find you've needed to move the test to a deeper hierarchy, and thus, need to re-write all your path resolution?

Have you ever had this problem for multiple files?

No more!

use FindBin;
use Path::FindDev qw(find_dev);
use lib find_dev($FindBin::Bin)->child('t','tlib')->stringify;

^ Should work, regardless of which test you put it in, and regardless of what $CWD happens to be when you call it.
