Not so much for the panes, but more for keeping a highly contextual environment per project or task. + +As the number of sessions grew, they became difficult to tell apart. For a few days now, I've had the idea of hashing the name of the session into a unique color, so that every session had its own `status-bg` color. + +First, the `tmuxHashColor` function: + +```sh +tmuxHashColor() { + local hsh=$(echo $1 | cksum | cut -d ' ' -f 1) + local num=$(expr $hsh % 255) + echo "colour$num" +} +``` + +In our `ns` function (new session), we hash the supplied session name to a color, then use `tmux send-keys` to set its `status-bg` color to it: + +```sh +ns() { + if [ -z $1 ]; then + 1=$(basename $(pwd)) + fi + tmux new-session -d -s $1 + local color=$(tmuxHashColor $1) + tmux send-keys -t $1 "tmux set-option status-bg $color" C-m + tmux send-keys -t $1 "clear" C-m + tmux attach -t $1 +} + +``` + +Now every session has it's own distinct `status-bg` color! |
