"caca driver ncurses" terminal does not work properly

[vladimiroltean]

Hi,

I am in need of a way to run feedgnuplot in a command-line-only environment, and the "dumb" terminal does not look too good. Compiling gnuplot 5.2 with "./configure --with-caca" gives me a feedgnuplot environment where:

• Replotting does not work. Although I get output, the following gets printed: "line 5: warning: refresh not possible and replot is disabled"
• I cannot kill feedgnuplot interactively (does not respond to Ctrl-c, Ctrl-z, q, x).

I know these probably sound more like caca terminal implementation bugs, but I don't know enough about how gnuplot works in order to be able to debug it. Can you please help identify the source of these issues?

Thanks,
Vladimir

P.S. this is not a joke

I've never used the caca gnuplot terminal, so don't know much about it. In general, feedgnuplot doesn't plot anything itself: it just generates a gnuplot command, which is sent to gnuplot, and IT does all the work. You can produce this command by passing --dump to feedgnuplot. Then you can pass it onto gnuplot yourself by either pasting it into a gnuplot session, or saving it to a file and invoking load "file" in gnuplot, where "file" is the --dump output. Try that. If it looks like you're still having issues, then gnuplot is at fault. The maintainer is relatively responsive to bug reports, so do talk to them via either the bug tracker or the gnuplot-beta mailing list.
