This module allows for data to be shared between invocations of a module on a given page, using Extension:VariablesLua. Use cases for this include counters and previewing Cargo storage.
Not to be confused with Module:UtilsArg.
local p = {}
VariablesLua = mw.ext.VariablesLua
function p.set(name, val)
local json = mw.text.jsonEncode(val)
VariablesLua.vardefine(name, json)
end
function p.get(name)
local json = VariablesLua.var(name)
if json == "" then
return nil
end
local val = mw.text.jsonDecode(json)
return val
end
function p.add(name, val)
local array = p.get(name) or {}
table.insert(array, val)
p.set(name, array)
return array
end
function p.counter(name, limit)

return val
end,

end,

end
