Data::Taxonomy::Tags - Represents a set of tags for any item
use Data::Taxonomy::Tags;
my $tags = Data::Taxonomy::Tags->new('perl tags cpan module system:meta');
print $_, "\n" for $tags->tags;
print $_, "\n" for $tags->categories;
Data::Taxonomy::Tags will basically take care of managing tags for an item
easier. You provide it with a string of tags and it'll allow you to call
methods to get all the tags and categories as well as add and delete tags from
the list.
- new($string[,\%options])
- The first argument is a string of tags. This string is stripped of any
leading and trailing whitespace. The second argument, which is optional,
is a hashref of options.
Returns a Data::Taxonomy::Tags object;
- "separator => ['\s+', ' ']"
- Specifies the regex pattern (or compiled regex) which will be used to
"split" the tags apart and the
character(s) used between tags when converting the object back to a
string. Make sure to escape any special characters in the regex pattern.
If the value is not an arrayref, then the same value is used
for both operations (and is escaped for the regex).
Defaults to "['\s+', '
']".
- "category => [':', ':']"
- Specifies the regex pattern (or compiled regex) which will be used to
"split" the tag name from it's optional
category and the character(s) used between the category and tag when
converting to a string. Make sure to escape any special characters in the
regex pattern.
If the value is not an arrayref, then the same value is used
for both operations (and is escaped for the regex).
Defaults to "[':',
':']".
- tags
- Returns an array or arrayref (depending on context) of
Data::Taxonomy::Tags::Tag objects.
- add_to_tags($tags)
- Processes the string and adds the tag(s) to the object.
- remove_from_tags($tags)
- Processes the string and removes the tag(s) from the object.
- remove_category($category)
- Removes all tags with the specified category.
- categories
- Returns an array or arrayref (depending on context) of the unique
categories.
- tags_with_category($category)
- Returns an array or arrayref (depending on context) of the tags with the
specified category
- as_string
- Returns the tag list as a string (that is, what was given to the
constructor). Overloading is used as well to automatically call this
method if the object is used in a string context.
