METHODS
priority
The priority of this scribe. Scribes with higher priority get tried first. Xattr is a low-priority scribe.
allowed_file
If this scribe can be used for the given file, then this returns true. This can be used with any file, if the filesystem supports extended attributes. I don't know how to test for that, so I'll just assume "yes".
allowed_fields
If this scribe can be used for the known and wanted fields, then this returns true. For Xattr, this always returns true.
if ($scribe->allowed_fields())
{
....
}known_fields
Returns the fields which this scribe knows about. This scribe has no limitations.
my $known_fields = $scribe->known_fields();read_meta
Read the meta-data from the given file.
my $meta = $obj->read_meta($filename);delete_field_from_file
Completely remove the given field. For multi-value fields, it removes ALL the values.
$scribe->delete_field_from_file(filename=>$filename,field=>$field);Helper Functions
Private interface.
replace_one_field
Overwrite the given field. This does no checking for multi-value fields.
$scribe->replace_one_field(filename=>$filename,field=>$field,value=>$value);BUGS
