- `theme_display_ruby`. Use `no` to completely hide all information about Ruby version. By default Ruby version displayed if there is the difference from default settings.
- `theme_display_vagrant`. This feature is disabled by default, use `yes` to display Vagrant status in your prompt. Please note that only the VirtualBox and VMWare providers are supported.

### Overrides
You can disable the theme default greeting, vi mode prompt, right prompt, or title entirely — or override with your own — by adding custom functions to `~/.config/fish/functions`:
- `~/.config/fish/functions/fish_greeting.fish`
- `~/.config/fish/functions/fish_mode_prompt.fish`
- `~/.config/fish/functions/fish_right_prompt.fish`
- `~/.config/fish/functions/fish_title.fish`
To disable them completely, use an empty function:
```fish
function fish_right_prompt; end
```
… Or copy one from your favorite theme, make up something of your own, or copy/paste a bobthefish default function and modify it to your taste!
```fish
function fish_greeting
set_color $fish_color_autosuggestion
echo "I'm completely operational, and all my circuits are functioning perfectly."
set_color normal
end
```
