------------------------------------------------------------------------
-- Name: p.name
-- Purpose: Find a template invocation name from a page name or a
-- mw.title object.
-- Description: This function detects whether a string or a mw.title
-- object has been passed in, and uses that to find a
-- template name as it is used in template invocations.
-- Parameters: title - full page name or mw.title object for the
-- template (string or mw.title object)
-- Returns: String
------------------------------------------------------------------------

function p.name(title)
if type(title) == 'string' then
title = mw.title.new(title)
if not title or #title.prefixedText == 0 or #title.interwiki > 0 then
error("name関数のtitle引数の値が不正です", 2)
end
elseif type(title) ~= 'table' or type(title.getContent) ~= 'function' then
error("name関数の第1引数は文字列かmw.titleオブジェクトでなければなりません", 2)
end
if title.namespace == 10 then

-- Exclude the prefix, unless we have something like "Template:Category:Foo", which can't be abbreviated to "Category:Foo".

-- Name: p.invocation
-- Purpose: Construct a MediaWiki template invocation.
-- Description: This function makes a template invocation from the
-- name and the arguments given. Note that it isn't
-- perfect: we have no way of knowing what whitespace was
-- in the original invocation, the named parameters will be
-- alphabetically sorted, and any parameters with duplicate keys
-- will be removed.
-- Parameters: name - the template name, formatted as it will appear
-- in the invocation. (string)
-- args - a table of template arguments. (table)
-- format - formatting options. (string, optional)
-- Set to "nowiki" to escape, curly braces, pipes and
-- equals signs with their HTML entities. The default
-- is unescaped.
-- Returns: String
