Is there any way to achieve tab completion in tmux's status line. Let me give a use-case:
bind-key v command-prompt "split-window -h 'exec vim %%'"
This is from my tmux.conf. It will be a great idea if only I could get paths to complete in the tmux statusline. I've looked around but did not find anything. Anyone has any ideas?
Thanks.

Is there any way to split a window in tmux without changing the current focus?
I'm running a script inside one of my tmux panes that occasionally runs "tmux split-window ..." with some command that takes a minute to complete and MAY request input.
I can end up trying to type input into one of the tmux panes but in the middle of my typing, the original pane executes "tmux split-window ..." and (mid word) my cursor shifts to the new pane, and I end up typing part of the input into the wrong pane.
Note: this answer is correct, but obsolete. The right way is to use -d flag for split-window command. I'm leaving this answer as a demonstration how to do some yak shaving with tmux.
A split-window command flag provided by tmux would be the right solution for this. Unfortunately tmux does not provide such command flag. Update: there is a -d split-window flag that does this.
The simple solution is to immediately switch to previous pane after split-window:
tmux split-window
tmux last-pane
This can be also written as a one liner:
tmux split-window\; last-pane
The downside of this solution is that *theoretically* you might end up writing a character in the wrong window if you type it in time interval between split-window and last-pane command execution.
Here another approach with the downside that it's more complex.
Create a new window in the background and get the pane_id of this window (note how this command is wrapped in $(...) because we want it executed in a subprocess:
pane_id=$(tmux new-window -d -P -F "#{pane_id}")
Now join the window we just created with the window where your cursor is located (will not change cursor focus):
tmux join-pane -b -t "$pane_id"
Add -h to the join-pane above if you want a horizontal split.
I recommend taking the first approach for it's simplicity. It's highly unlikely you'll have any practical issues with it.
Suppose have 3 panes in a tmux window: vim, vom, and vam
I want to access the pane title of the first pane as part of a keyboard mapping (forward command to vim if vim's in pane 1). It wasn't working as expected and I've narrowed it down to the following...
If I run:
tmux display-message "`tmux list-panes -F '#{pane_title}'`"
the result is:
vim
vom
vam
This is what I'd expect. If I try to run the same from a key mapping:
bind -n C-h run "tmux display-message \"`tmux list-panes -F '#{pane_title}'`\""
I get the title of the current pane repeated three times:
vom
vom
vom
Does run-shell execute in a different context or something?
Thanks for your help
Run tmux list-keys in the terminal and see what C-h gets mapped to. I get something like this:
bind-key C-t run-shell "tmux display-message "name1
name2
name3""
From the above, you can see the backtick interpolation happens at the moment when the key is bound, not later when the binding is executed.
I don't know how to get around this and you must be having a lot of pain because of so many nested commands.
Personally, when hacking tmux I always apply the rule of "get to the shell as soon as possible".
For your example that would mean:
keep the key binding simple: bind -n C-h run "/path/to/script.sh"
create a script, make it executable and put the rest of what you want to do in it. This would be its content:
tmux display-message "`tmux list-panes -F '#{pane_title}'\`"
I just did it and it worked for me locally. Hope that helps!
I am having an issue with Tmux where Control+E brings me to the end of a line outside of Tmux but not inside of Tmux. I have looked around for a solution but none seem to work. Any help would be greatly appreciated. My .tmux.conf can be seen here: https://gist.github.com/Julian25/6585115
if you are using zsh, try adding bindkey -e to your .zshrc file.
description of what's happening:
when minimizing a maximized pane, this message appears at bottom of terminal window: "Session not found: tmp"
pane appears to return to same place as initial/previous session
but the new tmp window (that was opened when the pane was first maximized) fails to close and appears in the list of windows (in the status bar at the bottom of tmux)
my hunch is kill-window -t tmp (in the below .tmux.conf code) is where things break. since executing a command in the tmp window appears to rename the window, kill-window -t tmp won't work.
so my question is: how could i alter .tmux.conf to prevent this from happening?
steps to recreate bug:
(note: you would need to have modified .tmux.conf for these commands to work)
start tmux and create session w/ at least two panes
maximize one pane using [prefix] + [up]
execute a shell command in maximized pane (*)
minimize pane using [prefix] + [down]
(*) if pane is maximized and minimized w/out executing a command in the shell this problem does not appear to occur. i.e. if you're editing a file in a pane, then maximize that pane, and only edit/save the file (w/out exiting and then executing another command), then minimize -- the bug doesn't occur.
30s youtube clip showing what happens: http://youtu.be/WMdOeJdOYuU
code that might be causing the error (from ~/.tmux.conf):
unbind Up
bind Up new-window -d -n tmp \; swap-pane -s tmp.0 \; select-window -t tmp
unbind Down
bind Down last-window \; swap-pane -s tmp.0 \; kill-window -t tmp
[edit: HERE IS THE SOLUTION]
thanks to a helpful #tmux irc'er (who has this link and whom i will happily give credit) this question is solved. i don't yet have enough cred to answer this question so i'm posting the solution here.
the solution is to add set-window-option -g allow-rename off to ~/.tmux.conf
this works b/c tmp doesn't get renamed so kill-window -t tmp can properly execute.
(thx for the help and feel free to answer this so i can give you credit!)
You want allow-rename set to off, at least for that one window:
set-window-option -g allow-rename off
Annoying question to have to ask! In bash (or anywhere.. like when editing this question) I can do CTRL + left|right to move left left or right to different bits of whitespace. With tmux running.. this does work.. it doesn't do anything. How do you do the same thing but with tmux?
Thank you.
You can do it by binding C-Left and C-Right to "send-keys M-b" and "send-keys M-f" in your ~/.tmux.conf file like this:
bind-key -n C-Left send-keys M-b
bind-key -n C-Right send-keys M-f
You don't. bash, respectively readline, has an idea of what you typed and can therefore jump as many characters until the next "word boundary". tmux does not have this information. Also, in tmux and the ANSI code space, I would interpret "end of line" in fact as \r\e[xB (with x being the size of the window), though that did not match up with your expectation.
