# blessed
|
|
|
|
A curses-like library for node.js.
|
|
|
|
Blessed was originally written to only support the xterm terminfo, but can
|
|
now parse and compile any terminfo to be completely portable accross all
|
|
terminals. See the `tput` example below.
|
|
|
|
I want this library to eventually become a high-level library for terminal
|
|
widgets.
|
|
|
|
## Example Usage
|
|
|
|
This will actually parse the xterm terminfo and compile every
|
|
string capability to a javascript function:
|
|
|
|
``` js
|
|
var Tput = require('blessed').Tput
|
|
, tput = Tput('xterm');
|
|
|
|
console.log(tput.setaf(4) + 'hello' + tput.sgr0());
|
|
```
|
|
|
|
``` js
|
|
var blessed = require('blessed')
|
|
, program = blessed();
|
|
|
|
program.on('keypress', function(ch, key) {
|
|
if (key.name === 'q') {
|
|
program.clear();
|
|
program.disableMouse();
|
|
program.showCursor();
|
|
program.normalBuffer();
|
|
process.exit(0);
|
|
}
|
|
});
|
|
|
|
program.on('mouse', function(data) {
|
|
if (data.action === 'mouseup') return;
|
|
program.move(1, program.rows);
|
|
program.eraseInLine('right');
|
|
if (data.action === 'wheelup') {
|
|
program.write('Mouse wheel up at: ' + data.x + ', ' + data.y);
|
|
} else if (data.action === 'wheeldown') {
|
|
program.write('Mouse wheel down at: ' + data.x + ', ' + data.y);
|
|
} else if (data.action === 'mousedown' && data.button === 'left') {
|
|
program.write('Left button down at: ' + data.x + ', ' + data.y);
|
|
} else if (data.action === 'mousedown' && data.button === 'right') {
|
|
program.write('Right button down at: ' + data.x + ', ' + data.y);
|
|
} else {
|
|
program.write('Mouse at: ' + data.x + ', ' + data.y);
|
|
}
|
|
program.move(data.x, data.y);
|
|
program.bg('red');
|
|
program.write(' ');
|
|
program.bg('!red');
|
|
});
|
|
|
|
program.on('focus', function() {
|
|
program.move(1, program.rows);
|
|
program.write('Gained focus.');
|
|
});
|
|
|
|
program.on('blur', function() {
|
|
program.move(1, program.rows);
|
|
program.write('Lost focus.');
|
|
});
|
|
|
|
program.alternateBuffer();
|
|
program.enableMouse();
|
|
program.hideCursor();
|
|
program.clear();
|
|
|
|
program.move(1, 1);
|
|
program.bg('black');
|
|
program.write('Hello world', 'blue fg');
|
|
program.setx((program.cols / 2 | 0) - 4);
|
|
program.down(5);
|
|
program.write('Hi again!');
|
|
program.bg('!black');
|
|
program.feed();
|
|
|
|
program.getCursor(function(err, data) {
|
|
if (!err) {
|
|
program.write('Cursor is at: ' + data.x + ', ' + data.y + '.');
|
|
program.feed();
|
|
}
|
|
|
|
program.charset('SCLD');
|
|
program.write('abcdefghijklmnopqrstuvwxyz0123456789');
|
|
program.charset('US');
|
|
program.setx(1);
|
|
});
|
|
```
