Test 1: check uint costructor:

\directlua{
barracuda = require "barracuda"
local c39, err = barracuda:barcode()
                          :new_encoder("code39")
assert(not err, err)
local err
local symbol
symbol, err = c39:from_uint(0, {text_hpos="center"})
assert(not err, err)

local canvas = barracuda:new_canvas()
symbol:draw(canvas)

local drv = barracuda:get_driver()
drv:ga_to_hbox(canvas, "mybox")
}\bigskip\leavevmode\box\mybox

\directlua{
local c39, err = barracuda:barcode()
                          :enc_by_name("code39")
assert(c39, err)
local e
local symbol
symbol, e = c39:from_uint(0123456789, {text_hpos="spaced",text_star=true})
assert(not e, e)

local canvas = barracuda:new_canvas()
symbol:draw(canvas)

local drv = barracuda:get_driver()
drv:ga_to_hbox(canvas, "mybox")
