Module:Type in location

From Wikitia
Jump to navigation Jump to search


For generating short descriptions for infoboxes of structures/small places such as dams and museums, which are often in the format of type in location. Example:

{{#invoke:Type in location|main|{{{type|}}}|{{{location|}}}|check-patterns = [Mm]useum;foo;bar}}

Description only shows if check-pattern is matched in type.

Multiple check-patterns can be specified as "pattern1;pattern2;pattern3" and so on.

Also has helper functions of prepareLoc (for removing extraneous from addresses) and generalLoc (for getting more general location from specific address) which can be used seperately.

What is specified in the |invalidadd= parameter will be added with a space if the check-patterns fail.

Setting |full-loc= gives the full of the location (with slight processing) instead of the more general location.

local plaintext = require("Module:Plain text")._main

function p._prepareLoc (text)
	text = plaintext(text)
	text = text..',' --comma at the end makes things convenient
	text = text:gsub('%b()', ', ') --remove things in brackets as etxtraneous information
			   :gsub('[^%s,]*%d[^%s,]*', '') --remove things with digits as generally being unecessary postal codes/road numbers etc
			   :gsub('(,%s-),', '%1') --fix possible blank seperated commas from previous cleanup
			   :gsub('%s%s', ' ') --fix possible extra spaces from previous cleanup
			   :gsub('^[%s,]*', '') --trim commas and spaces from beginning
			   :gsub('[%s,]*$', '') --trim commas and spaces from end
	return text

--Gets general location from more specific one for short descriptions
--i.e if a location is specified to be "P. Sherman 42 Wallaby Way Sydney, Australia", return "Sydney, Australia"
