Re: [NTG-context] Using lua to define a macro with one optional parameter in brackets

8 Jul 2015

      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() --- ?????

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
