[gentoo-user] How to extend the tmux status 'title' for each pane or window

Hi All,

I am using tmux and find it convenient especially for managing remote 
sessions, but I have noticed that the commands running in a session shown at 
the bottom right hand side, within the status line, are too short.  Can I 
extend the number of characters to be able to see more of the command being 
run at any time?

I only see a *maximum* length option in the manpage - presumably because tmux allocates as much space as possible to the left and right statuses, but space must be consumed by the window titles in the middle. 

Is it possible you can give the right hand side more room by reducing the maximum of the left?

I'm interested to know what you're displaying on the right - it's been so long since I set up tmux, I can't remember what the defaults are. Could you possibly post the output of `tmux show -g status-right`, please?

I have:

$ tmux show -g | grep -E 'status-[lr]'
status-left "#[fg=blue]#T"
status-left-attr none
status-left-bg default
status-left-fg default
status-left-length 20
status-right "#[fg=blue][#S]"
status-right-attr none
status-right-bg default
status-right-fg default
status-right-length 40
$

Thanks Stroller,

On the left status bar I see this: 

[0] 0:bash*

with one window open.  As I create more windows it adds to it like so:

[0] 0:bash  1:bash- 2:bash* 


The right hand side shows the prompt, or command being run, but not all of it 
if it is too long. 

This is the output you requested:

$ tmux show -g status-right
status-right ""#22T" %H:%M %d-%b-%y"

and this are the equivalent settings to yours:

$ tmux show -g | grep -E 'status-[lr]'
status-left "[#S]"
status-left-attr none
status-left-bg default
status-left-fg default
status-left-length 10
status-right ""#22T" %H:%M %d-%b-%y"
status-right-attr none
status-right-bg default
status-right-fg default
status-right-length 40

I don't have a ~/.tmux.conf yet.

It looks to me like I've merely swapped left and right panes because, presumably, I thought it looked better that way.

And I've removed the clock - that's one way you could reclaim some screen space. 

I seem to be a little tired, and not fully functional, right now, but you could do this (for example), like this:

    tmux set -g status-right "#22T" 

The relevant section of the man page is:

             status-left string                                                 
                     Display string to the left of the status bar.  string      
                     will be passed through strftime(3) before being used.  By  
                     default, the session name is shown.  string may contain    
                     any of the following special character sequences:          
                                                                                
                           Character pair    Replaced with                      
                           #(shell-command)  First line of the command's
                                                              output
                           #[attributes]     Colour or attribute change
                           #H                Hostname of local host
                           #h                Hostname of local host without
                                                              the domain name
                           #F                Current window flag
                           #I                Current window index
                           #D                Current pane unique identifier
                           #P                Current pane index
                           #S                Session name
                           #T                Current pane title
                           #W                Current window name
                           ##                A literal ‘#’


As I say, I don't seem to be firing on all cylinders right now, but it doesn't look to me like the "commands being run" are shown where you say they are, not on the far right, at least.

I think they're shown in the *middle* section of the status bar.

Where above you have said your display shows:

[0] 0:bash  1:bash- 2:bash* 

Then the first "0", in square brackets, indicates the name of the current session. Try this by opening a new terminal and running `tmux new-s -s test_sess`. 

I think that "bash" is the name of the command being run in each of your sessions.

You might like to try running the attached countdown.pl script and see how "the command being run" is displayed.

HTH, 

Stroller.

Right, on my default setup the clock is on the right, the number of windows on 
the left and the title in the middle.

As is the title shows:

"root@compaq:/usr/src/l"

instead of "root@compaq:/usr/src/linux".  This is what I mean of it being cut 
short.

Yes, they are shown in the middle, but on a 82x25 pixel terminal the title is 
displayed about 2/3 towards the right of the status bar, right against the 
clock.  See attached screenshot.

Running tmux set -g status-right "#32T" removed the clock and increased the 
real estate for the title bar.

Thanks again Stroller.

The "#22T" means (I think) to show the *first 22 characters* of the
title, cutting it off if it is too long.  You may just want to
increase that number to something that matches the room you have
available.

Yes, increasing the number extends the title in the middle, but I would 
ideally like a setting that extends it automatically to cover available space 
if needed.
