• Cross-platform
• Offloads rendering to the GPU for lower system load
• Uses threaded rendering for absolutely minimal latency

Basic features are under development for MacOs right now.

Last testing build for macOS (338b4c411ac62dc4bdf68b5c9b8e5da7d7bab8ca):

WPGU is an implementation of WebGPU for use outside of a browser and as backend for firefox's WebGPU implementation. WebGPU allows for more efficient usage of modern GPU's than WebGL. More info

You want to avoid a browser-based application to reduce memory and CPU consumption. Electron for example, uses Chromium under the hood so your user sees the same on Windows, Linux and macOS but Rio have same compatibility rendering based on WGPU.

Rio also relies on Rust memory behavior: Rust is a memory-safe language that employs a compiler to track the ownership of values that can be used once and a borrow checker that manages how data is used without relying on traditional garbage collection techniques. More info

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

• macOs path: ~/.rio/config.toml

Example of config.toml:

performance = "High"
height = 400
width = 600

Description: Set terminal WGPU rendering perfomance.

• 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.

See more in https://docs.rs/wgpu/latest/wgpu/enum.PowerPreference.html

# <performance> Set WGPU rendering perfomance
# default: High
# options: High, Low
# 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"

Description: Set terminal window height.

# <height> Set default height
# default: 400
height = 400

Description: Set terminal window width.

# <width> Set default width
# default: 400
width = 600

Description: Defines the column width of your console window. This mode is system dependant, and returns an error if you specify a column width that is not supported by your operating system.

# <width> Set default width
# default: 80 (macOs)
columns = 80

Description: Define the row height of your console window. This mode is system dependant, and returns an error if you specify a row height that is not supported by your operating system.

# <width> Set default width
# default: 25 (macOs)
rows = 25

• background - Set background color.
• cursor - Set cursor color.
• foreground - Set foreground color.
• tabs - Set tab color.
• tabs-active - Set active tab color.

[colors]
background = "#151515"
cursor = "#8E12CC"
foreground = "#FFFFFF"

• font_size - Set font size.

[style]
font_size = 16.0

Description: Set Rio terminal theme

• Modern
• Basic

# <theme> Set Rio terminal theme
# default: Basic
# options: Modern, Basic
theme = "Modern"
