TypeError: Cannot read property 'onLinkHover' of undefined

xterm-addon-webgl@latest (v0.5.1) does not work with xterm@latest (v4.4.0)

it throws error TypeError: Cannot read property 'onLinkHover' of undefined because xterm v4.4.0 does not have linkifier2 property on the terminal.

I think xterm-addon-webgl@0.5.1 was meant to be released as v0.6.0-beta.4

@Tyriar is webgl supposed to work with xterm v4.4?

I have the same issue, this is how I use xterm-addon-webgl:

const {WebglAddon} = require('xterm-addon-webgl');
const {Terminal} = require('xterm');

const webglAddon = new WebglAddon();
const terminal = new Terminal({
    scrollback: 1000,
    tabStopWidth: 4,
});

terminal.open(document.body);
terminal.loadAddon(webglAddon);

On the last line I have:

xterm-addon-webgl.js:1 Uncaught TypeError: Cannot read property 'onLinkHover' of undefined
    at new e (xterm-addon-webgl.js:1)
    at new e (xterm-addon-webgl.js:1)
    at t.activate (xterm-addon-webgl.js:1)
    at e.loadAddon (xterm.js:1)
    at e.loadAddon (xterm.js:1)

I think this happened because of an oversight by bumping the version in db30451

xterm-addon-webgl@0.5.1 is not compatible with xterm@0.4.0 so use 0.5.0 for now. I'll make a note on the releases page: https://github.com/xtermjs/xterm.js/releases

FYI @jerch

@Tyriar How could this happen? Only made a small bugfix in private code not touching any API stuff. Pending previous changes? I was not aware, that bugfix version jumps would publish on its own, sorry for that.

[Tyriar]

@jerch master moved on from 4.4 and I think webgl may have adopted internal naming changes since? Yep, bumping any addon versions will automatically publish, just like the main package.json.

Looks like this is still an issue in v0.6.0 even though the changelog says they are compatible.

Edit: Actually looks like webgl v0.6.0 does work in xterm v4.5.0 🎉

@UziTech phew, had me worried for a second 😄
