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


function p.CheckId(name)
	local itemData = mw.loadData("Module:ItemData")
    local itemTable = itemData.items[name]
    if itemTable == nil then return 'NoItem' end
    local IconName = string.gsub(itemTable.untranslated, ' ', '') .. 'Item'
	
	return IconName
end

--- Check if item is in given array.
--- @author User:Avaren
local function in_array(item, array)
	-- Should only use on short arrays
	local set = {}
	for _, l in ipairs(array) do
		set[l] = true
	end
	return set[item] ~= nil
end

--- Calculate the length of a table by iterating over every item in it.
--- @author User:Avaren
function p.tableLen(tbl)
	local count = 0
	for _, v in ipairs(tbl) do
		if v == nil then
			return count
		end
		count = count + 1
	end
	return count
end

return p
