Split of Reactive variables and publish as standalone library

[EwoutH]

To have this noted in this repo, for tracking:

Ideally, solara's reactive variables (which are signals) would be its own library... :)

The basic idea is that Solara's hybrid push/pull system has value on it's own, and could be published as a standalone library.

It doesn't necessarily need a new repo, it can just be published from this repo, and Solara can keep using the git version in this repo. The only difference it that you put it as an additional, standalone package on PyPI.

I did a little search into alternatives, and it seemed there aren't many that are well maintained.

• RxPY had one single commit in the last ~1.5 years.
• PySignal had their latest commit 4 years ago.

Seems there's room for a new player in town!

There is also https://pypi.org/project/psygnal/ but it's not a hybrid push/pull system like javascript signals (often are).

I know the owner of https://pypi.org/project/reactive and I asked if he's ok with transferring me the ownership (it's not being used).

That's really cool! Thanks for actively considering / working on this!

Also noticed https://pypi.org/project/signals

which is being worked on by @manzt and @rgbkrk

Ideally, we get a signals like standard/library in Python that solara uses or is compatible with. Looking at https://pypi.org/project/signals/0.1.0a4/ this is fully compatible API wise with what we have in mind, and also, the Jupyter notebook integration looks aligned with my version.

Thanks! Can I find the source code of signals anywhere? The new pre-release description on PyPI doesn't list a homepage, repo or anything in that regard.

[rgbkrk]

Good spelunking! We have not published it for broad use yet.

[manzt]

Yup, should be ready to share in the next week or so!

[EwoutH]

Thanks a lot for working on this! Very curious if you have anything to share at this point!
