Utilities for ANSI-BBS and compatible terminals.
WARNING This is still highly experimental and incomplete. Any/everything can change at any time!
ANSI-BBS refers to a set of standards and semi standards commonly used in the BBS world. ANSI escape sequences being the main area where various "standards" have evolved over the years but have never officially been formalized. This library attempts to slightly tame the anarchy.
If you're looking for something to really rock a modern terminal, this is probably not the place. You may be interested in something like terminal-kit or @blessed/neo-blessed instead.
Some, but not all of the standards at least partially dealt with here:
const { Terminal } = require('ansi-bbs-utils');
const term = new Terminal(socket);
term.setTerminalType('ansi-bbs');
term.fgColor('green').write('Hello, world!');term.ed(2)
.cuu().up()
.down(2)
.back().forward()
.left().right();// true color when available
term.setTerminalType('xterm-truecolor');
term.fgRGB(255, 0, 215); // produces 24-bit seq
// ...nearest match colors otherwise
term.setTerminalType('xterm-256');
term.fgRGB(255, 0, 215); // produces 8-bit/256 near match = 200
term.setTerminalType('ansi-bbs');
term.fgRGB(255, 0, 215); // produces nearest 16c color
// selection
term.red() // definitely red
.fgColor(9) // red
.fgColor(128, 0, 0) // red
.fgRGB(128, 0, 0) // alias to fgColor
.fgColor(160) // "Red3"
.sgr('red') // red
.sgr(31) // ...still red.
.redBG(); // OK fine, the background. But red.const twoFiftySix = term.getCapabilities().has('8bit-color');
term.addCapability('vtx'); // 🔥See LICENSE
