tmux-pop is a tiny TMUX plugin that flashes the active pane with a given color on move.
Using Tmux Plugin Manager (recommended)
set -g @plugin 'roosta/tmux-pop'
git clone https://github.com/roosta/tmux-popAdd this to the bottom of .tmux.conf
run-shell ~/path/to/repo/tmux_pop.tmux
Reload TMUX env
tmux source-file ~/.tmux.conftmux-pop defaults to using brightblack as the pop color, but it can be changed
in .tmux.conf
set -g @tmux-pop-color 'red'
The choice of color are limited to what is defined in message-command-style in tmux:
The colour is one of: black, red, green, yellow, blue, magenta, cyan, white, aixterm bright variants (if supported: brightred, brightgreen, and so on), colour0 to colour255 from the 256-colour set, default, or a hexadecimal RGB string such as ‘#ffffff’.
tmux-pop works by temporarily changing the terminal background, for this to work in say vim, you'd need a colorscheme that allows the background color to pass through. Plug: Srcery Vim and Emacs themes supports transparent background.
