Tmux and ZSH custom prompt : bug with window name
I have customized my ZSH prompt with oh-my-zsh to make it more readable and add information about git if I'm in a repository.
Example :bob@inf [~/docs] %
bob@inf [~/src/nicest] master %
(in a git repository)
It works well but I have some bugs with tmux
and the window name. It still display non sense value and I cannot disable it with automatic-rename off
(it just do not work, the window name change after each command), for the first example tmux use ~/docs
for the window name.
I'm not sure how I can fix it, I would like to keep my zsh prompt as it is, if can make change but would like to understand where is the problem ?
Another solution may be to redefine command settile
(from this answer) but I'm not sure how to do it the right way.
Solution 1:
I took a peek at oh-my-zsh and found a likely suspect.
When the value of the TERM environment variable starts with screen
(which it should under both screen and tmux), it uses a screen terminal control sequence to set the window’s name to
- (just before displaying a shell prompt)
the left-most portion of the “tilde compressed” path of the current working directory (..
followed by the last 13 characters or the entire path if it less than 15 characters) and - (just before starting a command)
the first “word” of about-to-be-run command (not countingssh
,sudo
, and a few others).
It sounds like it is working this way for you (you said that your window named changed to ~/docs
when you were in that directory). If you want to disable this automatic renaming, you can can disable it completely by setting the DISABLE_AUTO_TITLE shell parameter to true
in your .zshrc
:
DISABLE_AUTO_TITLE=true
If you just set this in an interactive shell, you will end up with an empty string for the current window’s name, but oh-my-zsh will stop updating the window before each prompt and command in that shell instance (it needs to be in your .zshrc
to affect all new shell instances).
Solution 2:
I know that the answer above gives you a solution, but another one is to simply add this option your the ~/.tmux.conf
set-option -g allow-rename off
