Gnuplot Development

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 thing 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 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
