Does liground send a quit command to engines before quitting?

[tsoj]

When I close LiGround, sometimes engine processes continue to exist and run. I also saw this happening with Nibbler, where the solution was to set quit commands to all engines, before quitting the program itself.

Hello @tsoj ,
thank you for the bug report.

There is a quit() method already, but I think it is not called on the program close event right now.

liground/src/renderer/engine/driver.js

Lines 186 to 199 in acbd326

	/**
	* Tell the engine to quit.
	*/
	async quit () {
	// check for already destroyed stream
	if (this.input.destroyed) {
	return
	}
	// wait for ready, then quit & wait for stream close
	await this.waitForReady()
	this._write('quit')
	await waitFor(this.input, 'close')
	}
