Documentation
This module provides the back end functionality of the Template:Description. If the template is passed an item name, this module pulls the item's description from Module:ItemData.
Usage
local p = {}
-- Grabs args from the parent frame
-- Trims and parses the args into a table, then returns the table
function norm()
local origArgs = mw.getCurrentFrame():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
-- Main entry point for the Module
function p.main()
-- get args from the Template
local args = norm()
-- Check if an item is given, return its description from
-- Module:ItemData if it item is specified
if args.item then
local itemData = require( "Module:ItemData" )
if itemData.items[args.item] == nil then
return 'None'
elseif itemData.items[args.item].description == '' then
return 'None'
else
return itemData.items[args.item].description
end
-- Check if text was given, return the text if so
elseif args.text then
return args.text
-- Error condition, item and text are not given
else
local errormsg = 'Improper usage. Please see [[Template:Description]] for help'
return errormsg
end
end
return p
