8 Jul 2015

      Thanx Taco for reply.

the minimal example see bellow not crashed, but \A macro is not created.
I don't Know in what could still be a problem. Example I am even more 
minimalize

Thanx Jaroslav

\starttext

\directlua{
xlsname='A'
interfaces.definecommand ('do'..xlsname, {
     arguments = { { "option", "string" }  },
     macro = function (opt_1)
        if #opt_1>0 then context(opt_1) else context('nothing') end
     end
})
interfaces.definecommand (xlsname, {
     macro = function ()
        context.dosingleempty()
              context['do'..xlsname]()
     end
})
}

Hi Taco.
full deployment is unfortunately not working.
Unfortunately I need to cycle create different macros whose names are variable. At this moment I can not deal with this:
--- context.doxlsname() --- ?????
context[‘do’..xlsname]()
...
Thanx Jaroslav Hajtmar
here is another minimal example:
\starttext
\def\linepointer{5}
\def\csvcell[#1,#2]{cell #1,#2}
\directlua{
xlsname='A'
interfaces.definecommand ('do'..xlsname, {
    arguments = { { "option", "string" }  },
    macro = function (opt_1)
          if #opt_1>0 then context('\\csvcell["'..xlsname..'",'..opt_1..']') else context('\\csvcell["'..xlsname..'",\\linepointer]') end
    end
})
interfaces.definecommand (xlsname, {
    macro = function ()
       context.dosingleempty()
       --- context.doxlsname() --- ?????
    end
})
}
\csvcell['Firstname',\linepointer]
\A
\A[5]
\stoptext
