NAME

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

VERSION

version 0.006

SYNOPSIS

Example with Moose:

  ### 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

Example with Moo:

    ### specification of type constraint with coercion
    package Foo;
    use Moo;
    use Types::Path::Tiny qw/Path AbsPath/;
    has 'directory' => (
        is       => 'rw',
        isa      => AbsPath,
        required => 1,
        coerce   => AbsPath->coercion,
    );
    ### usage in code
    Foo->new( directory => '.' ); # coerced to path('.')->absolute

DESCRIPTION

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.

SUBTYPES

This module uses Type::Tiny 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.

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 );
