Tmux status bar not displaying segments on Yosemite

[iakshay]

After upgrading to Yosemite, tmux status bar isn't showing properly (no segments are visible) and status bar has green background color.

Running tmux 1.9a, have the following lines in tmux config.

# Status bar customization
run-shell "powerline-daemon -q"
source /usr/local/lib/python2.7/site-packages/powerline/bindings/tmux/powerline.conf

What does powerline-config tmux source show?

[iakshay]

Shows nothing. Actually that command removed the green background color! But still no segments on the right.

[iakshay]

Is this a known issue? #150

powerline tmux right shows the segment output.

@iakshay I actually expected it to fail with “command not found”: if tmux is configured properly powerline-config is run from tmux configuration and green background indicates that it was not run. Wondering whether it works when running

set -g status-right '#(powerline-client tmux right -R pane_id=`tmux display -p "#D"`)'

explicitly from tmux. Also what is the output of

for e in COMMAND CONFIG ; do tmux show-environment -g POWERLINE_$e ; done

? It should be

POWERLINE_COMMAND=powerline
POWERLINE_CONFIG=powerline-config

if powerline was installed correctly. But there may be leftovers from whatever because tmux remembers environment from the point server was started and does not change it when client starts.

By the way, what powerline version are you using?

[iakshay]

I got this output

How can I check the version? IIRC, I just updated with pip using git yesterday :)

[ZyX-I]

Wondering where I did get POWERLINE_CONFIG: actual implementation is using POWERLINE_CONFIG_COMMAND and POWERLINE_CONFIG only for zsh/zpython overrides.

So test should look like

for e in {CONFIG_,}COMMAND ; do tmux show-environment -g POWERLINE_$e ; done

with the following result:

POWERLINE_CONFIG_COMMAND=powerline-config
POWERLINE_COMMAND=powerline

.

POWERLINE_CONFIG is used in shell bindings and its absense only indicates that server was not started from shell or that you were not using powerline in the shell you started tmux server from (most likely the second since I do not see powerline on the screenshot). This will be yet another consistency issue I will have to postpone after next major release though.

I have no idea how to check version for pip install git+git:// builds. I am not sure it is even saved though.

Also after updating did you restart tmux server? (It can be killed for sure with tmux kill-server, but all sessions are obviously lost.)

[iakshay]

Gotcha, just need to kill the server. I did try deleting and creating session but I think that didn't kill the tmux server.

Thanks alot.

Summary -

1. Running Mavericks, everything works fine.
2. Upgraded to Yosemite, right segments disappeared.
3. Upgraded powerline, thinking the issue might be resolved. Recreated tmux session, but didn't kill the tmux server.
4. Killed tmux server, and right segments are back.
