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:
- •
- 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 );
