[Octave-bug-tracker] [bug #53737] printing to svg gives error and no plot with gnuplot 5.2

[Rik]

Follow-up Comment #15, bug #53737 (project octave):

According to the 5.2 documentation for the svg terminal


set terminal svg {size <x>,<y> {|fixed|dynamic}}
{mouse} {standalone | jsdir <dirname>}
{name <plotname>}
{font "<fontname>{,<fontsize>}"} {{no}enhanced}
{fontscale <multiplier>}
{rounded|butt|square} {solid|dashed} {linewidth <lw>}
{background <rgb_color>}


So it looks like the svg terminal now resembles the other gnuplot terminals. 
In that case, we could make the case statement for svg look like the one for
pdf


    case "pdf"
      if (! isempty (opts.font) && ! isempty (opts.fontsize))
        f = sprintf ('font "%s,%d"', opts.font, opts.fontsize);
      elseif (! isempty (opts.font))
        f = sprintf ('font "%s"', opts.font);
      elseif (! isempty (opts.fontsize))
        f = sprintf ('font ",%d"', opts.fontsize);
      endif


If necessary, could add a feature to __gnuplot_has_feature__ and then test for
it before using the old syntax or the new syntax.
