Different remarks about gnuplot development

Hans's note:

Once we have lua in place it should not be that difficult to make a mechanism that works as follows:

  • context calls gnuplot and opens a socket
  • and starts waiting for gp to finish
  • when gnuplot needs dimensions it talks back via the socket
  • tex executes the command send by the socket
  • etc

it needs some thinking but i think that it is possible

What has to be fixed in m-gnuplot.tex

  • Is it possible to get rid of "^M" at the end of lines
  • Add
\defineGNUPLOThandle{eps}{postscript eps color}{eps}{texmfstart newpstopdf \GNUPLOTfile.eps}{\GNUPLOTfile.pdf}
  • [Urgently] remove start from
{\executesystemcommand{start /MIN pgnuplot \GNUPLOTfile.gpd}}
No need for /MIN and possibly use gnuplot instead of pgnuplot
  • perhaps some --iftouched switches

What has to be added to m-gnuplot.tex to support ConTeXt terminal

What has to be added to context.trm

High priority

  • [HTH] change \startMPcode and \startMPpage to something like \strartGNUPLOTgraphic (once the support in m-gnuplot is written)
  • fix the syntax for
set terminal context
  • write documentation
  • [HTH] add \switchtobodyfont[whateverisprovided]\strut to evert \sometxt: try using (implementing first) \GPtext instead of \sometxt
  • [HTH] improve syntax for points, currently \sometxt{\GPpoint{NR}}

Middle priority

  • support different font sizes
  • check if everything is documented well enough in help

Low priority

  • implement with_image: once it's clear how to do it
  • study the code for palettes, implement them and document them
  • (need some interference with the core code) improve the code for
draw_color_smooth_box(MODE_SPLOT) in graph3d.c -> color.c

Legend

  • [HTH] = Need Hans's or Taco's Help
