bindings defined in .tmux.conf.local cannot override ones defined in .tmux.conf

[kflu]

Escape in copy-vi-mode is bound to send-keys -X cancel. I want to change it to clear-selection in .tmux.conf.local. However, it doesn't take effect

Repro

Put below in .tmux.conf.local:

bind-key -T copy-mode-vi Escape     send-keys -X clear-selection

Now completely quit and restart tmux. Then do:

tmux list-keys | grep copy-mode-vi | grep Es

Actual Result

Escape is still bound to cancel

bind-key    -T copy-mode-vi Escape               send-keys -X cancel

Expected

I expect Escape should now bound to clear-selection.

It looks like I'll have to wrap it with run -b 'tmux bind ... in order for it to work:

# works
run -b 'tmux bind-key -T copy-mode-vi Escape     send-keys -X clear-selection 2> /dev/null || true'

Note that, for a binding NOT defined in .tmux.conf, I can define them WITHOUT the wrap:

# works, because `copy-mode-vi q` is not defined in .tmux.conf
bind-key -T copy-mode-vi q     send-keys -X cancel

I'm having the same issue and found it extremely frustrating. It seems like others are experiencing the same thing, as seen in #549.

I think this might be because of something that changed on tmux's end, because I remember this working properly before. For reference, I have tmux 3.0a on my system.

What I found to work is to edit .tmux.conf so that source -q ~/.tmux.conf.local happens after run 'cut -c3- ~/.tmux.conf | sh -s _apply_configuration'.

So you would edit this part like so:

# -- 8< ------------------------------------------------------------------------

run 'cut -c3- ~/.tmux.conf | sh -s _apply_configuration'

# -- user defined overrides ----------------------------------------------------

source -q ~/.tmux.conf.local

@gpakosz Could you comment on if this is a valid fix, or if it's idiotic in ways that I'm not aware of?

Hello there 👋

Can you please give the gh-571 a try?

• It's rebased on gh-514 which means you can control whether or not Oh my tmux! alters new-window, split-window and new-session bindings
• It should apply all bind / unbind commands found in ~/.tmux.conf.local last

[yhshin11]

@gpakosz Confirming that gh-571 worked for me. Thanks!

[gpakosz]

I realized gh-514 is likely not needed so I force pushed gh-571 with a single commit on top of master.

Can you please give it another try?

[yhshin11]

@gpakosz I can confirm that this is working in master. Cheers!

Hello again,

I changed the gh-571 branch again. Can you please give it a try?

There are 2 distinct needs that need to be addressed by Oh my tmux!

1. People wanting to change a binding, yet still benefiting form Oh my tmux! binding manipulation.
   This is the case when you e.g. want <prefix> w to create a new window instead of <prefix> c.

   unbind c
   bind w new-window
   

   And at the same time you want to leverage tmux_conf_new_window_retain_current_path=true so that bind w new-window automatically becomes bind w new-window -c #{pane_current_path}

2. People wanting to add additional bindings that are immune to Oh my tmux! manipulations. This is your need, and in such a case you now need to terminate your binding definition with #!important (inspired by CSS).

   bind-key -T copy-mode-vi Escape send-keys -X clear-selection #!important

I updated .tmux.conf the sample .tmux.conf.local in the gh-571 branch. I'm testing it a bit more and I'll merge it soon
