Dear all,

Forgive me if I sound naive.  I searched the archives, but could not
find the solution for my following problem:

I need to have line numbers for the text formatted in two columns.  The
numbers for left column shall appear in the left side and that for right
column shall appear in the right side of the page.  location=inmargin
option to the \setuplinenumbering doesn't help much.  Please take a look
at the following image:

which will give you an idea of my requirement.  Any help in this matter
will be highly apprecaited and thanks in advance.

Best

Radhakrishnan

I do not know how to automate what you want. An ugly solution is to 
specify the column breaks yourself, something like

\unprotect
\def\dosetuplinenumbering[#1]%
   {\getparameters[\??rn][\c!start=1,\c!step=1,#1]%
%    \global\linenumber\plusone
%    Do not reset linenumber. Why is this here?
   }
\protect


\starttext
\startcolumns
\setuplinenumbering[location=inleft]
   \startlinenumbering
     \input knuth
   \stoplinenumbering
   \column
   \setuplinenumbering[location=inright]
   \startlinenumbering[continue]
     \input knuth
   \stoplinenumbering
\stopcolumns
\stoptext

proof of concept:

\newcounter\TestNumber

\let\normaldodoplacelinenumber\dodoplacelinenumber

\def\dodoplacelinenumber
  {\doglobal\increment\TestNumber
   \xypos{lnm:\TestNumber}%
   \ifdim\MPx{lnm:\TestNumber}>.5\makeupwidth
      \swapmacros\inleftmargin\inrightmargin
   \fi
   \normaldodoplacelinenumber}

\setuplinenumbering[location=inleft]

\startcolumns
\startlinenumbering
\input tufte \endgraf
\input tufte \endgraf
\input tufte \endgraf
\stoplinenumbering
\stopcolumns

\stoptext

in order to let this work ok (spacing) we need to write a nice patch (and also use the opportunity to clean up some code) which will take a couple of hours, so not today ..
