tmux status bar configuration

Question

How is the status bar is customized  I noticed in this youtube video  at 3 05 - image below   the status bar looks very different than the default one that I see after installing tmux on my Mac OS X   In particular  I like how the middle of the status bar shows the current program and the left side shows the name of only the current session  In comparison  my setup shows the name of all of the sessions and doesn t show the current application  for the currently focused pane    If anyone could show me a sample configuration that could do this or show me where I can find the customization rules  that would be great  Thanks     Update  In case anyone is curious  I was able to customize a status bar that is similar to the one seen in the video  minor tweaks  and you can find my config file on my github if you d like to see an example

I have been playing about with tmux today, trying to customised a little here and there, managed to get battery info displaying on the status right with a ruby script.

Copy the ruby script from http://natedickson.com/blog/2013/04/30/battery-status-in-tmux/ and save it as:

 battinfo.rb in ~/bin

To make it executable make sure to run:

chmod +x ~/bin/battinfo.rb

edit your ~/.tmux.config and include this line

set -g status-right "#[fg=colour155]#(pmset -g batt | ~/bin/battinfo.rb) | #[fg=colour45]%d %b %R"

Do C-b   show which will show you all your current settings   green  nnn will find you which properties have been set to green  the default  Do C-b   set window-status-bg cyan and the bottom bar should change colour   List available colours for tmux  You can tell more easily by the titles and the colours as they re actually set in your live session  show  than by searching through the man page  in my opinion  It is a very well-written man page when you have the time though   If you don t like one of your changes and you can t remember how it was originally set  you can open do a new tmux session  To change settings for good edit    tmux conf with a line like set window-status-bg -g cyan  Here s mine  https   gist github com 9083598

I used tmux-powerline to fully pimp my tmux status bar  I was googling for a way to change to background of the status bar when your typing a tmux command  When I stumbled on this post I thought I should mention it for completeness   Update  This project is in a maintenance mode and no future functionality is likely to be added  tmux-powerline  with all other powerline projects  is replaced by the new unifying powerline  However this project is still functional and can serve as a lightweight alternative for non-python users

The man page has very detailed descriptions of all of the various options  the status bar is highly configurable   Your best bet is to read through man tmux and pay particular attention to those options that begin with status-  So  for example  status-bg red would set the background colour of the bar  The three components of the bar  the left and right sections and the window-list in the middle  can all be configured to suit your preferences  status-left and status-right  in addition to having their own variables  like  S to list the session name  can also call custom scripts to display  for example  system information like load average or battery time  The option to rename windows or panes based on what is currently running in them is automatic-rename  You can set  or disable it globally with  setw -g automatic-rename  on   off  The most straightforward way to become comfortable with building your own status bar is to start with a vanilla one and then add changes incrementally  reloading the config as you go 1 You might also want to have a look around on github or bitbucket for other people s conf files to provide some inspiration  You can see mine here2    1 You can automate this by including this line in your  tmux conf  bind R source-file    tmux conf    display-message  Config reloaded     You can then test your new functionality with Ctrlb Shiftr  tmux will print a helpful error message   including a line number of the offending snippet   if you misconfigure an option  2 Note  I call a different status bar depending on whether I am in X or the console - I find this quite useful
