Thanks Taco,
your solution helped me ... Based on initial tests, it seems that it
works correctly. I'll know more after thorough testing.
Once again, thank you many times.
Sincerely Jaroslav Hajtmar

Hello ConTeXist.
Within the one very complex problem I need to solve the following case. I want
using lua code to define a macro with one optional parameter in brackets.
Simplest solution I know is this:
\startluacode
interfaces.definecommand ('dolastname', {
arguments = { { "option", "string" } },
macro = function (opt_1)
if #opt_1>0 then context(opt_1) else context('nothing') end
end
})
interfaces.definecommand ('lastname', {
macro = function ()
context.dosingleempty()
context.dolastname()
end
})
\stopluacode
Best wishes,
Taco
