-- Module to implement use of a blacklist and whitelist for infobox fields
-- Can take a named parameter |qid which is the Wikidata ID for the article
-- if not supplied, it will use the Wikidata ID associated with the current page.
-- Fields in blacklist are never to be displayed, i.e. module must return nil in all circumstances
-- Fields in whitelist return local value if it exists or the Wikidata value otherwise
-- The name of the field that this function is called from is passed in named parameter |name
-- The name is compulsory when blacklist or whitelist is used,
-- so the module returns nil if it is not supplied.
-- blacklist is passed in named parameter |suppressfields (or |spf)
-- whitelist is passed in named parameter |fetchwikidata (or |fwd)
local p = {}
local cdate -- initialise as nil and only load _complex_date function if needed
-- Module:Complex date is loaded lazily and has the following dependencies:
-- Module:Calendar
-- Module:ISOdate
-- Module:DateI18n
-- Module:I18n/complex date
-- Module:Ordinal
-- Module:I18n/ordinal
-- Module:Yesno
-- Module:Formatnum
-- Module:Linguistic
--
-- The following, taken from https://www.mediawiki.org/wiki/Wikibase/DataModel#Dates_and_times,
-- is needed to use Module:Complex date which seemingly requires date precision as a string.
-- It would work better if only the authors of the mediawiki page could spell 'millennium'.
