#500 introduced the @catppuccin_reset option, which would reset most theme options. This is especially useful with the new tmux client-light-theme and client-dark-theme hooks.

However, with the current capabilities, users are not able to override any theme options if they wish to use the new tmux hooks: any user-defined options would be wiped by the @catppuccin_reset instruction.

Proposal: if @catppuccin_reset is enabled, the plugin resets all catppuccin_* and @thm_* options, and nothing else. This allows users to customize options as follows:

set-hook -g client-dark-theme {
  # First, reset all options.
  set -g @catppuccin_reset "true"
  run ~/code/github.com/catppuccin/tmux/catppuccin.tmux

  set -g @catppuccin_flavor "frappe"
  set -g @thm_red "red"
  set -g @catppuccin_host_icon " H "
  # etc.
  run ~/code/github.com/catppuccin/tmux/catppuccin.tmux
}
set-hook -g client-light-theme {
  # First, reset all options.
  set -g @catppuccin_reset "true"
  run ~/code/github.com/catppuccin/tmux/catppuccin.tmux

  set -g @catppuccin_flavor "latte"
  set -g @thm_red "red"
  set -g @catppuccin_host_icon " H "
  # etc.
  run ~/code/github.com/catppuccin/tmux/catppuccin.tmux
}

The plugin entry script could be updated as follows:

#!/usr/bin/env bash

# Set path of script
PLUGIN_DIR="$(cd "$(dirname "${BASH_SOURCE[0]}")" && pwd)"

if [[ "$(tmux show -gvq @catppuccin_reset)" == 'true' ]]; then
  # Reset all options.
  opts="$(tmux show -gq | cut -d ' ' -f 1 | grep -E '@catppuccin|@thm')"
  for opt in ${opts}; do
    tmux set -Ugq "${opt}"
  done
else
  # Otherwise, load the plugin.
  tmux source "${PLUGIN_DIR}/catppuccin_options_tmux.conf"
  tmux source "${PLUGIN_DIR}/catppuccin_tmux.conf"
fi

This additionally provides a complete plugin reset, so users no longer need to visually inspect tmux to find stale colors or options that need explicit resetting.
