Uso

Outra documentação: 

local p = {}

--[[--------------------------< inline_error >-----------------------

Render red error message inline (as opposed to the system error() in large font)
Add article to tracking category.

 ]]

function p.inline_error(arg, msg)
  return '<span style="font-size:100%" class="error citation-comment">Erro na predefinição wayback: Verifique <code style="color:inherit; border:inherit; padding:inherit;">&#124;' .. arg .. '=</code> value. ' .. msg .. '[[Categoria:!Páginas com erros na predefinição wayback]]</span>'
end

--[[--------------------------< trimArg >-----------------------

trimArg returns nil if arg is "" while trimArg2 returns 'true' if arg is ""
trimArg2 is for args that might accept an empty value, as an on/off switch like nolink=

 ]]

function p.trimArg(arg)
  if arg == "" or arg == nil then
    return nil
  else
    return mw.text.trim(arg)
  end
end
function p.trimArg2(arg)
  if arg == nil then
    return nil
  else
    return mw.text.trim(arg)
  end
end

--[[--------------------------< isdf >-----------------------

Given df argument, return "yes" or "no" confirming what it is
Default is "no". If df is nil or "", return "no".

 ]]

function isdf(df)

  if df == "yes" or df == "Yes" or df == "YES" or df == "y" or df == "Y" or df == "dmy" or df == "DMY" or df == "s" or df == "Sim" or df == "SIM" then
    return "yes"
  elseif df == "iso" or df == "ISO" then
     return "iso"
  end
  return "no"

end

--[[--------------------------< makedate >-----------------------

Given a year, month and day, convert into a full date while respecting df (dmy or mdy)

 ]]

function p.makedate(year, month, day, df)

  local nmonth, zmonth, zday
  local month_names = {"janeiro", "fevereiro", "março", "abril", "maio", "junho", "julho", "agosto", "setembro", "outubro", "novembro", "dezembro"}

  if not year or year == "" or not month or month == "" or not day or day == "" then
    return nil
  end

  zmonth = month
  month = month:match("0*(%d+)")                                      -- strip leading 0
  if tonumber(month) < 1 or tonumber(month) > 12 then
    return year
  end
  nmonth = month_names[tonumber(month)]
--  nmonth = os.date("%B", os.time{year=2000, month=month, day=1} )     -- Month in name form      
  if not nmonth then
    return year
  end

  zday = day
  day = day:match("0*(%d+)")
  if tonumber(day) < 1 or tonumber(day) > 31 then
    return nmonth .. " " .. year
  end                                      

  if df == "yes" then
    return day .. " de " .. nmonth .. " de  " .. year
  elseif df == "iso" then
    return year .. "-" .. zmonth .. "-" .. zday
  else
    return day .. " de " .. nmonth .. " de  " .. year
