Issue description

tmux_power_theme does not work when applied in extraConfig. It works only if I create manually a .tmux.conf file.

extraConfig of tmux HM module seems to not apply anything of tmux_power_theme as for example the theme, the upload and download speed, despite set to true.

I was having the same issue. I was able resolved it by putting the plugin settings in the extraConfig of the plugin itself instead of tmux.

{
    programs.tmux = {
        enable = true;
        terminal = "xterm-256color";
        historyLimit = 10000;
        plugins = with pkgs.tmuxPlugins; [
            {
                plugin = power-theme;
                extraConfig = ''
                    set -g @tmux_power_theme 'violet'
                '';
            }
            {
                plugin = resurrect;
                extraConfig = ''
                    set -g @resurrect-capture-pane-contents 'on'
                '';
            }
            {
                plugin = continuum;
                extraConfig = ''
                    set -g @continuum-restore 'on'
                '';
            }
            vim-tmux-navigator
        ];
        extraConfig = ''
            set-option -ga terminal-overrides ",xterm-256color:Tc"

            set -g prefix C-a
            unbind C-b
            bind-key C-a send-prefix

            unbind %
            bind \\ split-window -h

            unbind '"'
            bind - split-window -v

            unbind r
            bind r source-file ~/.config/tmux/tmux.conf

            bind -r j resize-pane -D 5
            bind -r k resize-pane -U 5
            bind -r l resize-pane -R 5
            bind -r h resize-pane -L 5

            bind -r m resize-pane -Z

            set -g mouse on

            set-window-option -g mode-keys vi

            bind-key -T copy-mode-vi 'v' send -X begin-selection
            bind-key -T copy-mode-vi 'y' send -X copy-selection

            unbind -T copy-mode-vi MouseDragEnd1Pane
        '';
    };

I tried your solution and it works with the power theme color, but it does not work for:

set -g @tmux_power_show_upload_speed true
set -g @tmux_power_show_download_speed true

[tgallacher]

Try moving any line that modifies the status-right into the power-theme config as well, e.g.

plugins = with pkgs.tmuxPlugins; [
   {
        plugin = power-theme;
        extraConfig = ''
            set -g @tmux_power_theme 'violet'

            set -g status-right '#{prefix_highlight} | %a %Y-%m-%d %H:%M'
            set -g status-right ...
        '';
    }
    ...
];
extraConfig = ''
 ...
''

The problem is that the extraConfig content is placed after where the plugins (and their config) is dumped into tmux.conf. When modifying the status-right this ordering conflict can cause issues.

The problem I mentioned above is actually reported in #3555

perhaps related. I have a similar issue with dracula plugin. The plugin does load but one of its sections seem to have issue accessing a non-existing tmp folder where it is expected to exists:

Perhaps some plugins require to be able to write to some tmp location for them to behave as expected.
