### specification of type constraint with coercion
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
DESCRIPTIONThis 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.
SUBTYPESThis 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, AbsFileThese are just like "Path" and "AbsPath", except they check "-f" to ensure the file actually exists on the filesystem.
Dir, AbsDirThese 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::TempBe 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 );
