This module implements the {{about}} hatnote template.

Usage

  • The about function implements the {{about}} template directly, using the frame and applying no options. This should probably only be used in {{about}}.
  • The _about function can be used from Lua to supply a custom arguments list (its first argument) and/or an options table (its second argument). Options include:
    • aboutForm A string that can be used to substitute the form of the initial "about" message. It should include two substitution points: the first for the page type (e.g. "article"), and the second for the description of what the page is about. It should also include a trailing space for easy concatenation or omission. Defaults to 'This %s is about %s. '.
    • sectionString Gives the page type string for when the named argument section is specified. Defaults to 'section'.

	args = args or {}
	checkType('_about', 2, options, 'table', true)
	options = options or {}
	local defaultOptions = {
		--whatever
	}
	for k, v in pairs(defaultOptions) do
		if options[k] == nil then options[k] = v end
	end

	local pageTypeStrings = {
		[0] = 'article',
		[14] = 'category'
	}
	local pageType = (args.section and 'section') or

		about = string.format('This %s is about %s. ', pageType, args[1])
	end

	return mHatnote._hatnote(about .. forSee)
