termsand

termsand is the sand simulation for your terminal that no one asked for sand3-small

how do i use it?

termsand is intended to work with tmux 3.4+

  1. cargo install termsand
  2. download sand.sh to somewhere
  3. bind it to a key in your tmux.conf like this:
bind-key e run-shell "./sand.sh"

how does it work?

termsand will take input from stdin and use that as the initial state for the simulation

the sand.sh wrapper script captures your current tmux pane and pipes it into termsand inside of a popup, like this:

tmux_1
