Dear list,
I have the following sample:
\starttext
\def\Persona{señor Juan Martínez}
     \def\Persona{señora María Pérez}
El/La \Persona\ ha aprobado.
     \stoptext
How can I replace "El/La" in text with a command that can assign the
proper article?
I could use the translate module, but the real case is more complex than
the previous sample.
What I need in the command is that it can check the first word in the
command \Persona and assign "el" or "la".
Which is the right way to do this?
\startluacode

local replacer = lpeg.replacer {
     ["señor"]  = "el señor",
     ["señora"] = "la señora",
}

function document.MaleOrFemale(str)
     context(lpeg.match(replacer,str))
end

\stopluacode

\unexpanded\def\MaleOrFemale#1%
   {\ctxlua{document.MaleOrFemale("#1")}}

\starttext

whatever \MaleOrFemale{señor Juan Martínez} and \MaleOrFemale{señora 
María Pérez}

\stoptext
