Module:Utils

This module provides utility functions used from other modules.

Usage

Add the following line of code at the top of your file.

local Utils = require("Module:Utils")

-- You may then call functions from this module in your script. For example:
local tableLength = Utils.tableLen(myTable)

---

local p = {}

--- Trims and parses the args into a table, then returns the table
function p.normalise(args)

	for k, v in pairs(args) do
		v = mw.text.trim(tostring(v))
		if v ~= '' then
			args[k] = v
		end
	end

	return args
end

--- Trims and parses the args into a table, then returns the table

function p.normaliseArgs(frame)
	local origArgs = frame:getParent().args
	local args = {}

	for k, v in pairs(origArgs) do
		v = mw.text.trim(tostring(v))
		if v ~= '' then
			args[k] = v
		end
	end

	return args
end

    local itemTable = itemData.items[name]

end

--- Check if item is in given array.

	-- Should only use on short arrays
	local set = {}
	for _, l in ipairs(array) do
		set[l] = true
	end

end

--- Calculate the length of a table by iterating over every item in it.
