Feature: option to disable theming

[poetaman]

As per #511 (comment), please add an option to disable theming of panes and borders. That will 1) enable user to use another plugin that could handle theming in a more automated way, and/or 2) save user time/effort to change terminal theme in two places (one in their terminal emulator settings, and another in .tmux.conf.local of .tmux).

Example plugin that could do dynamic theming is showcased here: tmux/tmux#2931 (comment)

Hello @poetaman 👋

I know I'm coming back late with a solution. You can try the gh-536 branch if you still need to disable theming

[poetaman]

Hi @gpakosz 👋👋

Not a problem, I'll give it a try in next 24 hours, and report back.

See the new .tmux.conf.local sample, add tmux_conf_theme=disabled to your ~/.tmux.conf.local copy

Hello @poetaman,

Did you get the chance to test the branch?

[poetaman]

@gpakosz I looked at the branch, it does disable the theming. Thanks! Thought it also changes the contents of status bar from using utf characters to something simpler?

[gpakosz]

I'm not sure what you call "from using utf characters to something simpler".

It does decode unicode character escapes with

_decode_unicode_escapes() {
  printf '%s' "$*" | perl -CS -pe 's/(\\u([0-9A-Fa-f]{1,4})|\\U([0-9A-Fa-f]{1,8}))/chr(hex($2.$3))/eg' 2>/dev/null
}

e.g. it transforms \u0061 to a:

$ cut -c3- ~/.tmux.conf | sh -s _decode_unicode_escapes '\u0061'
a%

Look at the screenshots below:

Also, is there a way to route global/window option array pane-colours to derive color for different elements of .tmux status bar? Tmux added pane-colours array to be able to set and get global/window/pane 16 color palette.

Check the tmux feature here: tmux/tmux#2815 (comment)

I don't see anything special in the screenshot.

When you disable theming, Oh my tmux! doesn't use tmux_conf_theme_status_left or tmux_conf_theme_status_right any more.

The second screen just looks like the default status-left and status-right values, except that maybe you're displaying the current path?

Does the following return what you set in your conf?

$ tmux show -g status-left

$ tmux show -g status-right

[poetaman]

@gpakosz Got it, it does return what I see. There is one more intention: to adapt the theme of status bar on the fly as I change the tmux pane-colours array. What would that take? A step that could be needed for that is to keep using tmux_conf_theme_status_left and tmux_conf_theme_status_right but have a 16-color scheme that picks colors from global or window pane-colours array (if set). Might require adding a "16-color" theme option.

Also, is there a way to route global/window option array pane-colours to derive color for different elements of .tmux status bar? Tmux added pane-colours array to be able to set and get global/window/pane 16 color palette.

I didn't know about pane-colours until you mentioned it. I tried the following

$ tmux set -g status-right '#[fg=colour1]foo'

Then

$ tmux set -g 'pane-colours[1]' '#ffffff'

And it didn't change the colour in status-right (with my terminal theme, I expected the colour to change from red to white).

But the following kinda works

$ tmux set -g status-right '#[fg=#{pane-colours[1]}foo'

Then changing pane-colours[1] updates status-right accordingly. But that's just because of how tmux variables work.

In any case, Oh my tmux! is not the proper place to implement such a thing.
