Peter Hedwig has already done some work on it: http://peter.affenbande.org/gnuplot/ What his patch does: one calls gnuplot normally, and then, when you say set term lua dashed fontsize 15 "dashed fontsize 15" is parsed by lua. Then, gnuplot does its work, and calls functions: set_linestyle(3) set_color(...) draw_line(...) What Peter did was a mapping from C to lua, so the actual code that does "draw_line" is actually implemented in lua and can easily be changed and/or adapted without recompiling gnuplot. He now "converts" those function calls into TikZ Code, but that could easily be adapted into anything. So: output has already been implemented (and would "only" need to be adapted), while input might need some tweaking. I'm sometimes using a rather simple C++ library which opens gnuplot and pipes "set terminal ...", "plot ..." commands to gnuplot, so one can pass a C table to gnuplot. I could take a look at how it's done there. How do you imagine passing lua tables to gnuplot? Mojca PS: no need to say that even though his terminal is much more popular (it's the only decent LaTeX terminal I know) than the one for ConTeXt, I have seen zero discussion on the gnuplot mailing list about any intentions to integrate that code into gnuplot core. ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___________________________________________________________________________________
