Hello,

Is it possible to get the current width of a column from a paragraph into Lua ?

it all depends on where and how you access that but normally the width

Hello Hans,

I try to get the equivalent of \the\hsize in Lua, in order to render some verbatim text to the current width of the column.

Thank you for your help,
Pierre-François.

Both dimensions are in scaled points.

\starttext

\cldcontext{tex.hsize}

\cldcontext{tex.dimen["textwidth"]}

\stoptext

I've found a workaround by passing the value as an argument to the lua code :

\def\stopzonetexte
  {\ctxlua{userdata.traiterbuffer(buffers.getcontent('zonetexte'),[==[\the\hsize]==])}

Now, I try to figure how to get em size in points.

Thank you !

tex.hzize / 2^16 gives me the expected value !

This is a lot to learn  :)

Take a look into util-dim.la and search for the number.todimen function which can be used to convert scaled points into points.

\starttext

\startluacode

context(tex.hsize)
context.par()
context(number.topoints(tex.hsize))
context.par()
context(number.topoints(tex.hsize,"%0.5f"))

\stopluacode

\stoptext

Wolfgang
