About tui-realm 👑

tui-realm is a framework for tui and ratatui to simplify the implementation of terminal user interfaces adding the possibility to work with re-usable components with properties and states, as you'd do in React. But that's not all: the components communicate with the ui engine via a system based on Messages and Events, providing you with the possibility to implement update routines as happens in Elm. In addition, the components are organized inside the View, which manages mounting/umounting, focus and event forwarding for you.

And that's also explains the reason of the name: Realm stands for React and Elm.

tui-realm also comes with a standard library of components, which can be added to your dependencies, that you may find very useful. Don't worry, they are optional if you don't want to use them 😉, just follow the guide in get started.

Get started 🏁

⚠️ Warning: currently tui-realm supports these backends: crossterm, termion

Add tui-realm to your Cargo.toml 🦀

If you want the default features, just add tuirealm 1.x version:

tuirealm = "^1.9.0"

otherwise you can specify the features you want to add:

tuirealm = { version = "^1.9.0", default-features = false, features = [ "derive", "serialize", "with-termion" ] }

Supported features are:

  • derive (default): add the #[derive(MockComponent)] proc macro to automatically implement MockComponent for Component. Read more.
  • serialize: add the serialize/deserialize trait implementation for KeyEvent and Key.
  • tui: use the tui-rs terminal UI library
  • ratatui: use the ratatui terminal UI library
  • crossterm: use the crossterm terminal backend
  • termion: use the termion terminal backend

Deprecated feature flags:

  • with-crossterm
  • with-termion

⚠️ You can enable only one backend at the time and at least one must be enabled in order to build.
❗ You don't need tui as a dependency, since you can access to tui types via use tuirealm::tui::

Enabling other backends ⚠️

This library supports two backends: crossterm and termion, and two high level terminal TUI libraries: tui and ratatui. Whenever you explicitly declare any of the TUI library or backend feature sets you should disable the crate's default features.

❗ You can never have more than one backend and one UI library enabled at the same time

Example using the termion backend:

tuirealm = { version = "^1.9.0", default-features = false, features = [ "termion", "derive", "tui" ] }

Example using the ratatui UI library:

tuirealm = { version = "^1.9.0", default-features = false, features = [ "ratatui", "derive", "crossterm" ]}

Still confused about how tui-realm works? Don't worry, try with the examples:

  • demo: a simple application which shows how tui-realm works

    cargo run --example demo

Standard components library 🎨

Tui-realm comes with an optional standard library of components I thought would have been useful for most of the applications. If you want to use it, just add the tui-realm-stdlib to your Cargo.toml dependencies.

Community components 🏘️

These components are not included in tui-realm, but have been developed by other users. I like advertising other's contents, so here you can find a list of components you may find useful for your next tui-realm project 💜.
