Add support for the parent element (what is passed to Terminal.open) being in a different (same origin) window. Accesses to DOM APIs such as requestAnimationFrame and devicePixelRatio thus need to be scoped to the corrent window, instead of assuming that it's the same as the window/global scope where the code is running. This is done by inferring a parent window at the creation time, and then storing it in CoreBrowserService, which is already passed to most places that need it. To catch future regressions, an ESLint rule that checks for global accesses is added (it uses AST selectors via the no-restricted-syntax rule). This should also be applicable when the parent element is an iframe. Fixes #3758
xterm-addon-canvas
An addon for xterm.js that enables a canvas-based renderer using a 2d context to draw. This addon requires xterm.js v5+.
The purpose of this addon is to be used as a fallback for the webgl addon when better performance is desired over the default DOM renderer, but WebGL2 isn't supported or performant for some reason.
Install
npm install --save xterm-addon-canvas
Usage
import { Terminal } from 'xterm';
import { CanvasAddon } from 'xterm-addon-canvas';
const terminal = new Terminal();
terminal.open(element);
terminal.loadAddon(new CanvasAddon());
See the full API for more advanced usage.
