NAME

       Test::BDD::Cucumber::Model::TagSpec - Encapsulates tag selectors

VERSION

       version 0.11

DESCRIPTION

       Try and deal with the crazy-sauce tagging mechanism in a sane way.

OVERVIEW

       Cucumber tags are all sortsa crazy. This appears to be a direct result of trying to shoe-horn the syntax in to something you can use on the
       command line. Because 'Cucumber' is the name of a gem, application, language, methodology etc etc etc look of disapproval.

       Here is some further reading on how it's meant to work: <https://github.com/cucumber/cucumber/wiki/Tags>. This is obviously a little
       insane.

       Here's how they work here, on a code level: You pass in a list of lists that look like Lisp expressions, with a function: "and", "or", or
       "not". You can nest these to infinite complexity, but the parser is pretty inefficient, so don't do that. The "not" function accepts only
       one argument.

       eg:

       @important AND @billing: "[and =" 'important', 'billing']>

       (@billing OR @WIP) AND @important: "[ and =" [ or => 'billing', 'wip' ], 'important' ]>

       Skipping both @todo and @wip tags: "[ and =" [ not => 'todo' ], [ not => 'wip' ] ]>

ATTRIBUTES

   tags
       An arrayref representing a structure like the above.

	TagSet->new({
	       tags => [ and => 'green', 'blue', [ or => 'red', 'yellow' ], [ not => 'white' ] ]
	})

METHODS

   filter
       Filter a list of Scenarios by the value of "tags"

	my @matched = $tagset->filter( @scenarios );

       If "tags" is empty, no filtering is done.
