--[[ <pre>
Implements helper templates for [Module:Infobox recipe]
{{GETotal}} and {{GETotalqty}}
Adds all prices together and creates an easy to parse number
--]]
local p = {}
local geprice = require('Módulo:Mercado')._price
--[[
For simple sets, 1 item at a time
{{GETotal|a|b|c}} will add the prices of a, b, and c
Does not allow quantities of items
Technically unlimited
--]]
function p.simple(frame)
local args = frame:getParent().args
local prices = {}
for _, v in ipairs(args) do
table.insert(prices,geprice(v))
end
return p._main(prices)
end
--[[
For stuff that's a but more complex
{{GETotalqty|name1=a|qty1=4|name2=b|qty2=1/4}}
Will add together the price of a * 4 and b / 4
Can recognize and parse vulgar fractions
All fractions and decimals will be truncated off the final price
Technically limited to 20, can be expanded as needed

Helper function to parse vulgar fractions
If not readable as a vulgar fraction (i.e. no '/' character)
Returns nil, even if it can be read as a number
--]]
function frac(num)
if not num then
return nil
elseif not num:find('/') then
return nil

---- Module Access Point ----
Modified version of quantity.
Will add together the price of a * 4 and b / 4
Can recognize and parse vulgar fractions
All fractions and decimals will be truncated off the final price
Technically unlimited
To use:
variable 'a' = array of {quantity,"item name", etc...}
variable 'b' = number of unique items to be included
--]]

local qtyx = a[i] or 1
local qtyret = tonumber(qtyx) or frac(qtyx) or 1
