Automatically adjust window width in tmux

tmux

Is there a way to set tmux so that it automatically adjusts window width when I switch to the pane so that it will be wide axactly as the longest (visible on screen) line in the file I have open?

I'm doing this manually with the command

:resize-pane -R 10
or
:resize-pane -L 10

I always have to guess the number and when I switch to another pane I have to do it again

Note that this functionality is relevant only to vertical panes.

There does not seem to be a way to do this automatically. You can, however use the mouse:

 mouse-resize-pane [on | off] 
    If on, tmux captures the mouse and allows panes to be
    resized by dragging on their borders.

The command to do this is join-pane in tmux 1.4.

join-pane [-dhv] [-l size | -p percentage] [-s src-pane] [-t dst-pane]  
    (alias: joinp)
    Like split-window, but instead of splitting dst-pane and creating
    a new pane, split it and move src-pane into the space.  This can
    be used to reverse break-pane.

To simplify this, I have these binds in my .tmux.conf for that:

# pane movement
bind-key j command-prompt -p "join pane from:"  "join-pane -s '%%'"
bind-key s command-prompt -p "send pane to:"  "join-pane -t '%%'"

The first grabs the pane from the target window and joins it to the current, the second does the reverse.

You can then reload your tmux session by running the following from within the session:

$ tmux source-file ~/.tmux.conf
