reblessed

THIS FORK ONLY CONTAINS FIXES & ROUGH PATCHES TO MAKE chjj/blessed AND THEN reblessed USABLE IN NIX-OS BUILDS

NOT FOR EVERYDAY USAGE, NO IMPROVEMENTS OVER kenan238/reblessed, EVEN DOWNGRADES

If you'd like to request a feature, make a new issue

A curses-like library with a high level terminal interface API for node.js.

The library's official author, "chjj", seems to have abandoned the project, as the last commit was in 2016. All forks have also died, so I took matters into my own hands and forked the project.

Blessed is a fantastic project, so I revived this masterpiece from the dead under the name "Re-Blessed", as I wasn’t able to find any other TUI libraries that had exactly what a TUI application needed!

Install

Latest release

Latest source code

git clone [email protected]:shamansir/everblessed.git

Example

This will render a box with line borders containing the text 'Hello world!', perfectly centered horizontally and vertically.

NOTE: It is recommend you use either smartCSR or fastCSR as a reblessed.screen option. This will enable CSR when scrolling text in elements or when manipulating lines.

const everblessed = require('everblessed');

// Create a screen object.
const screen = everblessed.screen({
  smartCSR: true
});

screen.title = 'my window title';

// Create a box perfectly centered horizontally and vertically.
const box = everblessed.box({
    top: 'center',
    left: 'center',
    width: '50%',
    height: '50%',
    content: 'Hello {bold}world{/bold}!',
    tags: true,
    border: {
        type: 'line'
    },
    style: {
        fg: 'white',
        bg: 'magenta',
        border: {
            fg: '#f0f0f0'
        },
        hover: {
            bg: 'green'
        }
    }
});

// Append our box to the screen.
screen.append(box);

// Add a png icon to the box
const icon = everblessed.image({
    parent: box,
    top: 0,
    left: 0,
    type: 'overlay',
    width: 'shrink',
    height: 'shrink',
    file: __dirname + '/my-program-icon.png',
    search: false
});

// If our box is clicked, change the content.
box.on('click', (data) => {
    box.setContent('{center}Some different {red-fg}content{/red-fg}.{/center}');
    screen.render();
});

// If box is focused, handle `enter`/`return` and give us some more content.
box.key('enter', (ch, key) => {
    box.setContent('{right}Even different {black-fg}content{/black-fg}.{/right}\n');
    box.setLine(1, 'bar');
    box.insertLine(1, 'foo');
    screen.render();
});

// Quit on Escape, q, or Control-C.
screen.key(['escape', 'q', 'C-c'], (ch, key) => {
    return process.exit(0);
});

// Focus our element.
box.focus();

// Render the screen.
screen.render();
