NAME¶
Path::FindDev - Find a development path somewhere in an upper hierarchy.
VERSION¶
version v0.5.3
DESCRIPTION¶
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 :("; }
FUNCTIONS¶
find_dev¶
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 $result = Path::FindDev::find_dev('/some/path');
Which by design inhibits your capacity to specify an alternative set in code.
EXAMPLE USE-CASES¶
Have you ever found yourself doing
use FindBin; use lib "$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.
