zle_highlight and yank

zle_highlight and yank

[Yuri D'Elia]

Yanking text seems to ignore any setting in zle_highlight. This is
confirmed by setting zle_highlight=(none) and seeing that yank still
highlights the text in standout.

I would have expected it to respect the paste: style.

Or maybe it's a good idea that it doesn't, to differentiate between a
terminal paste and a regular one. But then again, I'd like a yank: style
in there.

I guess it's a bug that (none) doesn't disable the paste: style, but
you can explicitly put in paste: to disable it if you want, eg
zle_highlight=(none paste:)

I really only wanted to disable yank highlighting, which I find
distracting since I often know exactly what I just previously cut.

But I do find highlighting for paste generally useful on the other hand.

Try this:

    f() {
      zle .$WIDGET "$@"
      integer start end
      if (( YANK_START > YANK_END )); then
        start=$YANK_END end=$YANK_START
      else
        end=$YANK_END start=$YANK_START
      fi
      region_highlight+=("$start $end bg=blue")
      zle -f 'yank'
    }
    zle -N yank f

You will want to change 'bg=blue' to whatever your default colors are;
for some reason specifying "none" doesn't override the 'standout'
highlighting.

"zle -f" was added in zsh-5.2, for older versions just comment it out.

Cheers,

P.S. It'd be nice to have built-in min() and max() math functions..
