Support Notebook 7

[jtpio]

Looking at the code, there seems to be some components that expect to work on a LabShell only:

jupyter-ai/packages/jupyter-ai/src/selection-watcher.ts

Line 102 in 9c69a7b

if (!(shell instanceof LabShell)) {

Which can prevent using the extension in other lab-based applications such as Notebook 7.

Maybe there can be a way to make jupyter-ai work in more lab-based applications? Even if only a limited set of features is available.

For instance this could allow for code completions in Notebook 7.1 (based on #465). Below is an example running https://github.com/krassowski/jupyterlab-transformers-completer:

Maybe the following could be replaced by app.shell.currentWidget?

jupyter-ai/packages/jupyter-ai/src/selection-watcher.ts

Line 108 in 9c69a7b

this._mainAreaWidget = args.newValue;

Since currentWidget is part of the JupyterFrontEnd.IShell interface:

• https://github.com/jupyterlab/jupyterlab/blob/846a7b06b4d9ae098035987a9573258adc116b58/packages/application/src/frontend.ts#L277

Thanks for bringing this up. We have some early UX designs for a slightly different (optional) UX that would work well in notebook. Certainly the inline completer stuff in #465 should work in notebook, but we would like to have a chat experience as well. @andrii-i do you have some of the UX mocks we did for the lightweight chat UX for cells (I think we called in a "popup UX" or something?

[andrii-i]

Here are mockups for "in-editor dialog/popup UI" as we call it:

1. On in-editor text selection or text area interaction, icon to the left of the cell appears
   

2. When icon is clicked, in-editor Jupyter AI dialog/popup UI appears

Just FYI, the chat could already by placed in the left or right sidebar:

I think that the selection-oriented pop-up could be very useful for reformatting and infill tasks (and not hard to implement given CodeMirror6 uses its own, programmatic selection layer). I could also see the chat as optionally configurable mini-window that can be dragged around, though if you are interested in enabling users today, placing the chat in the sidebar is a no-brainer.
