Is there an onBeforeDestroy() callback?

Is there any like onBeforeDestroy() callback or something similar to call before terminal got destroy term.destroy()?
Thanks,

No, I'm afraid. But it's good idea to add also onAfterDestroy().

To add event you only need to add:

fire_event('onBeforeDestroy', [])

and probably good idea to check if the value is false and don't execute destroy().

if (fire_event('onBeforeDestroy', []) === false) {
   return this;
}

I am wrapping jquery.terminal in a Svelte component, can you point me to the right direction of where should I call fire_event method?

import { onMount, onDestroy } from 'svelte';

export let termIns: JQueryTerminal = Object.create(null);
let jqTermContainerEl: HTMLElement;
let termDefaultOpts: JQueryTerminal.TerminalOptions;

onMount(() => {
    termIns = jQuery(jqTermContainerEl).terminal(termInterp, {...termDefaultOpts, ...termOpts});
});

onDestroy(() => {
    //Should we call it here before termIns.destroy()?
    termIns.fire_event('onBeforeDestroy', []) // <= ERR: fire_event is not a function
    if (termIns) termIns.purge().destroy();
});

Thanks,

No, the code fire_event is supposed to go inside jQuery Terminal source code. This not a public API. It needs to be added inside destroy method.

I will be waiting for the new update then, if you ever plan to add this hook.
