gnuplot.vim

This is a fork of vlaadbrain/gnuplot for gnuplot syntax highlighting.

This also sets commentstring, makeprg and also makes K work for gnuplot help.

I also added some Ruby code to enable interaction with a gnuplot session running in the background. This part is is highly untested and probably not working for many corner cases. What it does is:

• Creates a $gnuplot Ruby global variable, which has methods:
  • .exec(cmd)to execute a gnuplot command
  • .replot to replot
  • .err to return the output of last gnuplot command
  • .last to return the last command issued to gnuplot
• Maps <Space> in Visual and Normal mode to send line/range to Gnuplot.
• Maps [g and ]g in Normal mode to move to previous/next plot in Multiplot mode.

This is a simple plugin, just sends the lines to Gnuplot as is. This has some shortcomings, for example: Assume you have set label "x" at 0, 0 line, that is already plotted. If you change this line to set label "x" at 1, 1 and re-send to Gnuplot, it will not update the label position but add a new label --just like it would do in a Gnuplot session. To avoid this kind of behavior I suggest always giving an id to labels, arrows and objects (e.g. set label 1 "x" at 1, 1).

How to Install

I suggest using junegunn/vim-plug.
