TMUX min attacher - reattach to numbered tmux sessions
I launch tmux as my login shell from the terminal by calling just
tmux - by default, this creates one session per window. This is
usually what I want, except when I accidentally hit Cmd-W and close a
Opening a new window then causes a new session to be created, instead of the accidentally-detached session to be re-attached. This was getting pretty annoying to me, so I wrote this program.
- Get Rust 1.10
- (optionally) check the PATH that this sets - setting PATH from your shell init files won't cut it here.
- Set your terminal to run the
tmux_min_attacherbinary as the command for new windows.
- Open and close tabs/windows and be happy
But but but... rust!?
"You could do this from the shell!" - Yep, and I did, for the longest time. Sadly, however, my shell startup is slow enough that this significantly delayed startup of new shells, and what's worse, caused stuff I'd typed ahead of the shell startup to be missed. Hence, Rust. This is fast enough, let me tell you. (No missed typeahead, at least!)
I've tested this with the 1.10 release of Rust. It uses
nix to get access to
stable&safe-ish unix interfaces for
exec and such, so should be
pretty stable - I've been using this code for a few months now. Let me
know in the
anything breaks for you. Or, wow, even better, submit a pull request!
