Configuration file

The configuration should be the following paths otherwise Rio will use the default configuration.

MacOS and Linux configuration file path is ~/.config/rio/config.toml.

Windows configuration file path is C:\Users\USER\AppData\Local\rio\config.toml (replace "USER" with your user name).

Updates to the configuration file automatically triggers Rio to render the terminal with the new configuration.

Cursor​

Default cursor is Block.

Other available options are: _ and |

cursor = '▇'

Editor​

Default editor is vi.

Whenever the key binding OpenConfigEditor is triggered it will use the value of the editor along with the rio configuration path.

An example, considering you have VS Code installed and you want to use it as your editor:

editor = 'code'

Whenever OpenConfigEditor runs it will trigger $ code <path-to-rio-configuration-file>.

Blinking Cursor​

Default is false

blinking-cursor = false

Ignore theme selection foreground color​

Default is false

ignore-selection-foreground-color = false

Enable Kitty Keyboard protocol​

Default is false

use-kitty-keyboard-protocol = false

Performance​

Set WGPU rendering performance

  • High: Adapter that has the highest performance. This is often a discrete GPU.
  • Low: Adapter that uses the least possible power. This is often an integrated GPU.
performance = "High"

Themes​

Rio looks for a specified theme in the themes folder.

  • MacOS and Linux: ~/.config/rio/themes/dracula.toml
  • Windows: C:\Users\USER\AppData\Local\rio\themes\dracula.toml
theme = "dracula"

Padding-x​

Define x axis padding (default is 10)

padding-x = 10

Option as Alt​

This config only works on MacOs.

Possible choices: both, left and right.

option-as-alt = 'left'

Window​

  • width - define the intial window width.

    • Default: 600

  • height - define the inital window height.

    • Default: 400

  • mode - define how the window will be created

    • Windowed (default) is based on width and height
    • Maximized window is created with maximized
    • Fullscreen window is created with fullscreen

  • foreground-opacity Set text opacity.

    • Default: 1.0.

  • background-opacity Set background opacity.

    • Default: 1.0.

  • blur Set blur on the window background. Changing this config requires restarting Rio to take effect.

    • Default: false.

  • background-image Set an image as background.

    • Default: None

  • macos-hide-toolbar-buttons - (MacOS only) Hide toolbar buttons

Example:

[window]
width = 600
height = 400
mode = "Windowed"
foreground-opacity = 1.0
background-opacity = 1.0
blur = false
macos-hide-toolbar-buttons = false

Using blur and background opacity:​

[window]
foreground-opacity = 1.0
background-opacity = 0.5
blur = true

Demo blur and background opacity

Using image as background:​

[window.background-image]
path = "/Users/hugoamor/Desktop/musashi.png"
opacity = 0.5
width = 400.0
height = 400.0
x = 0.0
y = -100.0

Demo image as background

Fonts​

Configure fonts used by the terminal

Note: You can set different font families but Rio terminal will always look for regular font bounds whene

You can also set family on root to overwrite all fonts.

[fonts]
family = "cascadiamono"

You can also specify extra fonts to load:

[fonts]
extras = [{ family = "Microsoft JhengHei" }]

The font configuration default:

[fonts]
size = 18

[fonts.regular]
family = "cascadiamono"
style = "normal"
weight = 400

[fonts.bold]
family = "cascadiamono"
style = "normal"
weight = 800

[fonts.italic]
family = "cascadiamono"
style = "italic"
weight = 400

[fonts.bold-italic]
family = "cascadiamono"
style = "italic"
weight = 800

Scroll​

You can change how many lines are scrolled each time by setting this option. Scroll calculation for canonical mode will be based on lines = (accumulated scroll * multiplier / divider).

If you want a quicker scroll, keep increasing the multiplier. If you want to reduce scroll speed you will need to increase the divider.

You can use both properties also to find the best scroll for you.

  • Multiplier default is 3.0.
  • Divider default is 1.0.

Example:

[scroll]
multiplier = 3.0
divider = 1.0

  • mode - Define navigation mode

    • NativeTab (MacOs only)
    • CollapsedTab
    • BottomTab
    • TopTab
    • Breadcrumb
    • Plain

  • clickable - Enable click on tabs to switch.

  • use-current-path - Use same path whenever a new tab is created.

  • color-automation - Set a specific color for the tab whenever a specific program is running.

[navigation]
mode = "CollapsedTab"
clickable = false
use-current-path = false
color-automation = []

Shell​

You can set shell.program to the path of your favorite shell, e.g. /bin/fish.

Entries in shell.args are passed unmodified as arguments to the shell.

Default:

  • (macOS) user login shell
  • (Linux/BSD) user login shell
  • (Windows) powershell

Shell Examples​

  1. MacOS using fish shell from bin path:
shell = { program = "/bin/fish", args = ["--login"] }
  1. Windows using powershell:
shell = { program = "pwsh", args = [] }
  1. Windows using powershell with login:
shell = { program = "pwsh", args = ["-l"] }
  1. MacOS with tmux installed by homebrew:
shell = { program = "/opt/homebrew/bin/tmux", args = ["new-session", "-c", "/var/www"] }

Startup directory​

Directory the shell is started in. If this is unset the working directory of the parent process will be used.

This configuration only works if use-fork is disabled

working-dir = "/Users/raphael/Documents/"

Environment variables​

The example below sets fish as the default SHELL using env vars, please do not copy this if you do not need it.

env-vars = []

Disable render when unfocused​

This property disables the renderer process when Rio no longer has focus.

disable-renderer-when-unfocused = false

Use fork​

Defaults for POSIX-based systems (Windows is not configurable):

  • MacOS: spawn processes
  • Linux/BSD: fork processes
use-fork = false

Colors​

Defining colors in the configuration file will override any colors set in the theme if you're using a theme.

The default configuration is without a theme.

Example:

[colors]
background = '#0F0D0E'
foreground = '#F9F4DA'
cursor = '#F38BA3'
tabs = '#443d40'
tabs-active = '#F38BA3'
green = '#0BA95B'
red = '#ED203D'
blue = '#12B5E5'
yellow = '#FCBA28'

Bindings​

You can create custom key bindings for Rio terminal, more information

[bindings]
keys = [
  { key = "q", with = "super", action = "Quit" },
  # Bytes[27, 91, 53, 126] is equivalent to "\x1b[5~"
  { key = "home", with = "super | shift", bytes = [27, 91, 53, 126] }
]

Log level​

This property enables log level filter. Default is "OFF".

[developer]
log-level = "OFF"
