Change / refresh / close page?

Hi! Thank you a lot for your work on Eel. I’m wondering if there is a way to open, re-open, or refresh the html page in the very same window? Unfortunately, I couldn’t find this information.

I’m using Jinja2 templates for different views. As the program runs, the rendered templates are saved under the same name (index.html) and then should to be re-opened. However, doing ee.start("index.html") for the second time opens a new window beside the previous one. To add to this, the following OSError appears in the process:

OSError: [WinError 10048] Only one usage of each socket address (protocol/network address/port) is normally permitted: ('localhost', 8000)
2018-05-22T20:00:29Z <Greenlet "Greenlet-0" at 0x1ece5058a48: _process_message({'call': 1.5296098246811638, 'name': 'select_new_t, <geventwebsocket.websocket.WebSocket object at 0x0)> failed with OSError

but actually does not seem to affect the program’s functionality.

In case if opening another html page in the same window or refreshing it is not possible, is there a way to simply close the old window?

Hello! Thanks a lot for inventing Eel. It’s truly wonderful. I was getting a lot of errors when changing pages. I managed to make everything work as expected by doing some changes to eel.init.py file.

In case anyone needs it, please give it a try. If someone spot something wrong that might be with it, please also share it.

All I did was to move away the _websockets.remove((page, ws)) call from _websocket(ws) to _websocket_close function and slightly modify a couple more of thing in the latter function. Just as follows:

• note that I set _websocket_close to accept one additional parameter now.

def _websocket_close(page, ws):
    if _on_close_callback is not None:
        sockets = [p for _, p in _websockets]
        _on_close_callback(page, sockets)
    else:
        sleep(5.0)
        _websockets.remove((page, ws))
        if len(_websockets) == 0:
            sys.exit()

@ChrisKnott, thank you! I’m going to use this feature in my next Eel script.
