Support to tabs, custom key bindings, performance improvements and other updates

· aproximadamente 4minutos

This post also includes changes from v0.0.13 and v0.0.12.

Highlights​

  • Navigation.
  • Custom key bindings.
  • Performance updates.
  • Color automation for tabs.

Rio allows to choose navigation between the following options:

  • CollapsedTab
  • BottomTab
  • TopTab
  • Breadcrumb

You can set the navigation mode in the configuration file. An example of configuration:

[navigation]
mode = "BottomTab"
use-current-path = true
clickable = false

Note: BottomTab and TopTab does not support click mode yet.

Below some images with different navigation setups:

  • Second image: TopTav navigation wayland.

Sugarloaf performance improvements​

Performance improvements with Sugarloaf de-duplication of input data.

Before an average sugarloaf.stack call would cost around "~253.5µs" and now it does cost an average of "~51.5µs".

The algorithm is effective whenever the terminal has a lot of repetition like empty spaces. The benchmark test below was made rendering 100.000 characters that had repetition:

The de-duplication algorithm in the renderer considerably reduced the initial rendering time from avg 6ms to 2ms and using Rio in a large screen (>=136 columns) has dropped from 36ms to 8ms.

Color automation for navigation​

Rio allows to specify color overwrites for tabs based on program context.

The example below sets #FFFF00 as color background whenever nvim is running.

The configuration would be like:

[navigation]
color-automation = [
  { program = "nvim", color = "#FFFF00" }
]

Custom key bindings​

Now you can configure custom key bindings for Rio terminal.

Below an example of two custom key bindings:

[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] }
]

For example, in the first binding will tell Rio to close the terminal every time that "q" key is pressed along with "super" (in MacOS the "super" key is "command").

More info about custom key bindings in docs/default-key-bindings.
