Path::Tiny types and coercions for Moose and Moo


version 0.005


  ### specification of type constraint with coercion

  package Foo;

  use Moose;
  use Types::Path::Tiny qw/Path AbsPath/;

  has filename => (
    is => 'ro',
    isa => Path,
    coerce => 1,

  has directory => (
    is => 'ro',
    isa => AbsPath,
    coerce => 1,

  ### usage in code

  Foo->new( filename => 'foo.txt' ); # coerced to Path::Tiny
  Foo->new( directory => '.' ); # coerced to path('.')->absolute


This module provides Path::Tiny types for Moose, Moo, etc.

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.


This module uses Type::Tiny to define the following subtypes.


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


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.


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 );
