New action idea about changing color change-color

[fsc0]

There are good change-actions already,
But I think this change-color action also gonna helps users a lot with their color (and font style) power,
and makes good synergy, combination with other change-actions.
So, I'm guessing it has good potentials.

The concept script like this.
I'm still thinking about better example. 😅

#!/usr/bin/env bash
seq 10 | fzf --multi --color current-fg:white,current-bg:black --bind 'focus:transform:
if (( FZF_SELECT_COUNT > 3 )); then
	echo -n "change-header:Over 3 detected"
	echo "+change-color(current-fg:italic:green,current-bg:red)"
else
	echo "change-color(reset)" # back to original --color?
fi'

Thanks, and hope you doing well.

Thanks for the suggestion. A few points.

• Would this actually benefit users, or just create confusion if base colors keep changing?
• Changing the color palette is expensive — fzf’s renderer isn’t optimized to avoid full redraws when it changes.
• You can limit the number of selections with --multi 3
• Header, label, and prompt all support ANSI colors. So you can still change some colors dynamically.

  fzf --header $'\x1b[33myellow'

My init thought is it's most like sub-fancy feature so far.

I see, I also thought about this.
For now, keep the idea as maybe possible plan.

You're right, this wasn't good example at all. 😅

Tbh, this idea comes from my n script.
While using that script,
I realize there's no way to hide initial cursor hightlight (fg+, current-fg).
So, I have to see this pos 0 (initial position) to pos(n) movement that happens in very short of time.

That is no issue in normal situation,
but on my script, this pos blink is bugging me like unfinished 1% task.
So, I thought make fg+ color just like fg (basically no focus highlight) until pos changes.
This is origin of change-color idea.

But like you said, it's expensive compared to actual benefits.
Maybe fork time or need better idea to handle this my own issue.
Thanks for the answer. 👍
