Hi,
I am writing some extensions which I need. The extensions have different
purposes, but I'd like to ensure, that one of them has run before the other
ones are run.
What is a good way to do this? (no busy wait if not necessary)
In each of the extensions I am listening for the notebook to be loaded like
this:
/////////// BEGIN
function load_ipython_extension() {
if (Jupyter.notebook !== undefined &&
Jupyter.notebook._fully_loaded) {
if (!initialized) {
init();
}
} else {
if (!initialized) {
events.on('notebook_loaded.Notebook', () => {
init();
});
}
}
}
/////////// END
Then in init happens the actual work.
This was a practice suggested in some issue on Github and I already adopted
that, but how can I be sure that extension A runs before extensions B, C
and D, regardless of the specifics of what they do? Is there some event I
could listen to, which contains the name of the extension? Maybe something
like:
/////////// BEGIN
events.on('extension_loaded.ExtensionName')
/////////// END
Or a simple way to introduce such an event myself, without changing the
notebook source code itself, maybe some generic event sending, where I can
put in any name I want for the event and then listen for that in the other
extensions?
