Latest byobu in Precise ignores byobu-ctrl-a settings, treats CTRL-A like Emacs

Bug Description

After the most recent update, byobu-ctrl-a ran when I logged in. I selected option (1) (Screen mode). However, hitting CTRL-A does nothing any more (so CTRL-A, c, which used to create a new window, now just types the letter "c"). This is true regardless of what I choose in byobu-ctrl-a.

The current version I'm running is:

$ byobu -v
byobu version 5.9
tmux 1.6

Doh, sorry Graham.

I made a few changes to byobu-ctrl-a this weekend to get it to work in tmux. I must have broken something....

Can you paste the output of:
 $ cat ~/.byobu/keybindings.tmux ?

One followup... The fact that byobu-ctrl-a ran was introduced by byobu 5.9 -- previously, byobu-ctrl-a was not supported by tmux.

So I tried to reproduce this as follows, but it seems to be working as desired...

1) rm -f ~/.byobu/keybindings.tmux
2) F5 refresh profile
3) press ctrl-a
4) byobu-ctrl-a script runs, prompting for selecting 1 or 2
5) select 1
6) press "ctrl-a c" and it creates a new window

Then I do this:
1) rm -f ~/.byobu/keybindings.tmux
2) F5 refresh profile
3) press ctrl-a
4) byobu-ctrl-a script runs, prompting for selecting 1 or 2
5) select 2
6) 'asdfasdf' then press "ctrl-a" and watch the cursor go to the beginning of the line

I am experiencing the same thing as Graham since the package from the PPA got updated to the 5.9 version.

I too use tmux 1.6.

Hi Dustin,

Following your steps above, I always get the emacs / start-of-line behaviour, regardless of whether I choose option 1 or 2 in byobu-ctrl-a.

Here are the contents of ~/.byobu/keybindings.tmux:

unbind-key -n C-a
set -g prefix ^A,F12
bind a send-prefix

What Graham describes in his latest message also applies to me.

Oh, hmm... I'm still running Oneiric, and I have byobu 5.9 but tmux 1.5. You're on tmux 1.6.

I'll install tmux 1.6 now and see if I can reproduce the issue...

Dustin Kirkland  (kirkland) wrote :

Aha... Tmux 1.6 changelog shows:
 * Drop the ability to have a list of keys in the prefix in favour of two
  separate options, prefix and prefix2.
 * Flag -2 added to send-prefix to send the secondary prefix key.

And that breaks us :-( I'll need to work around this....

Ugh, this is going to be a pain... We'll have to have two different configuration file options for tmux 1.5 users, and one for tmux 1.6 users.

Dustin Kirkland  (kirkland) wrote :

Okay, fix committed.

Note that users affected by this (users who upgraded to byobu 5.9) will need to manually run byobu-ctrl-a one time to fix their ~/.byobu/keybindings.tmux file. Sorry!
