Divorce — tmux session switcher

Problem

Jumping between tmux sessions is friction: remember names, type tmux switch-client -t …, or leave the keyboard for a mouse menu. Creating a session for “this repo on this branch” is the same ritual every time.

Constraints

• Must work inside and outside tmux (switch-client vs attach).
• Depend only on tools people already have for this workflow: tmux, fzf, git.
• Stay a small Rust binary—no daemon, no config service.

What I built

divorce is a Rust CLI with two primary modes:

• divorce fzf — list open sessions (excluding the current one when already inside tmux), pick with fzf, then switch or attach depending on context. Cancel fzf to leave the session unchanged.
• divorce new — create-or-attach via tmux new-session -A, auto-naming from the project folder and current git branch (or an explicit name).

Optional tmux binding (prefix + d) sources a small conf that runs the fuzzy switcher.

Result

Session hopping and “new session for this worktree” become one keystroke-friendly command instead of a multi-step shell ritual—with behaviour that matches whether you are already attached to tmux.
