Changes
replace another argument name with a hardcoded value
local function makeInvokeFunc(funcName)
return function (frame)
local args = getArgs(frame, {
valueFunc = function (key, value)
if type(value) == 'string' then
value = value:match('^%s*(.-)%s*$') -- Remove whitespace.
if key == headingArg 'heading' or value ~= '' then
return value
