Getting started

Install

Add anathema to your Cargo.toml file.

...
[dependencies]
anathema = { git = "https://github.com/togglebyte/anathema/" }

Note

Even though efforts are made to keep this guide up to date there are possibilities of changes being made and published before they reach this guide.

At the time of writing, Anathema should be considered alpha (but almost beta!).

A basic example

Render a border around three lines of text, placing the text in the middle of the terminal.

// src/main.rs
use anathema::prelude::{Backend, Document, TuiBackend};
use anathema::runtime::Runtime;

fn main() {
    let doc = Document::new("@index");

    let mut backend = TuiBackend::builder()
        .enable_alt_screen()
        .enable_raw_mode()
        .hide_cursor()
        .finish()
        .unwrap();
    backend.finalize();

    let mut builder = Runtime::builder(doc, &backend);
    builder.default::<()>("index", "templates/index.aml").unwrap();
    builder
        .finish(&mut backend, |mut runtime, backend| runtime.run(backend))
        .unwrap();
}

// templates/index.aml
align [alignment: "center"]
    border
        vstack
            text [foreground: "yellow"] "You"
            text [foreground: "red"] "are"
            text [foreground: "blue"] "great!"

Prelude

Anathema has two convenience modules:

The prelude can be used to bootstrap your application, as it contains the Runtime, Document etc.

#![allow(unused)]
fn main() {
use anathema::prelude::*;
}

and components is suitable for modules that only contains Components.

#![allow(unused)]
fn main() {
use anathema::components::*;
}

See the crate documentation for more information.
