Synopsis
### 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
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 );
