NAME ^

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

VERSION ^

version 0.011

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:

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 );
