NAME

MooseX::Types::Path::Tiny - Path::Tiny types and coercions for Moose

VERSION

version 0.012

SYNOPSIS


            

              
              
### specification of type constraint with coercion
package Foo;
use Moose;
use MooseX::Types::Path::Tiny qw/Path Paths AbsPath/;
has filename => (
  is => 'ro',
  isa => Path,
  coerce => 1,
);
has directory => (
  is => 'ro',
  isa => AbsPath,
  coerce => 1,
);
has filenames => (
  is => 'ro',
  isa => Paths,
  coerce => 1,
);
### usage in code
Foo->new( filename => 'foo.txt' ); # coerced to Path::Tiny
Foo->new( directory => '.' ); # coerced to path('.')->absolute
Foo->new( filenames => [qw/bar.txt baz.txt/] ); # coerced to ArrayRef[Path::Tiny]

DESCRIPTION

This module provides Path::Tiny types for Moose. It handles two important types of coercion:

  • coercing objects with overloaded stringification

  • coercing to absolute paths

It also can check to ensure that files or directories exist.

SUBTYPES

This module uses MooseX::Types to define the following subtypes.

Path

Path ensures an attribute is a Path::Tiny object. Strings and objects with overloaded stringification may be coerced.

AbsPath

AbsPath is a subtype of Path (above), but coerces to an absolute path.

File, AbsFile

These are just like Path and AbsPath, except they check -f to ensure the file actually exists on the filesystem.

Dir, AbsDir

These are just like Path and AbsPath, except they check -d to ensure the directory actually exists on the filesystem.

Paths, AbsPaths

These are arrayrefs of Path and AbsPath, and include coercions from arrayrefs of strings.

CAVEATS

Path vs File vs Dir

Path just ensures you have a Path::Tiny object.

File and Dir check the filesystem. Don't use them unless that's really what you want.

Usage with File::Temp

Be careful if you pass in a File::Temp object. Because the argument is stringified during coercion into a Path::Tiny object, no reference to the original File::Temp argument is held. Be sure to hold an external reference to it to avoid immediate cleanup of the temporary file or directory at the end of the enclosing scope.

A better approach is to use Path::Tiny's own tempfile or tempdir constructors, which hold the reference for you.


            

              
              
Foo->new( filename => Path::Tiny->tempfile );
