@svelterm/vt100

VT100/xterm terminal emulator: an ANSI escape-sequence parser feeding a cell grid, plus Svelte views for rendering it. Powers the embedded terminals in svelterm, but has no dependency on svelterm — the core emulator is plain TypeScript.

npm install @svelterm/vt100

Emulator

import { Terminal } from '@svelterm/vt100'

const term = new Terminal(80, 24)
term.write('\x1b[1;32mhello\x1b[0m world\r\n')
// term.grid holds styled cells; term.cursor the cursor position

Parser (the raw escape-sequence event stream), Cell/Color/Attr (the grid vocabulary), and keyEventToBytes (browser KeyboardEvent → terminal input bytes) are exported for building your own plumbing.

Svelte views

• @svelterm/vt100/svelte — TerminalView, renders a Terminal into the DOM (canvas-free, styled text).
• @svelterm/vt100/EmbeddedTerminalDom — a terminal wired to a TerminalStream for DOM rendering.
• @svelterm/vt100/EmbeddedTerminalRegion — the same, rendered into a svelterm <svt-region> cell area for terminal-in-terminal use.

The Svelte views need svelte ^5 (an optional peer dependency); the emulator itself runs anywhere.
