How to discover all experimental_ and beta_ features

Using Streamlit
1

Is there a command line option or single web page that lists all experimental_ and beta_ features?

Hi @fredzannarbor :wave:

You should be able to access experimental features by downloading Streamlit Nightly.

Happy Streamlitin’! :balloon::raised_hands:

Best,

Will this miss anything?

~/.virtualenvs/nightly_unity/lib/python3.8/site-packages/streamlit

 grep -ir experimental_ *

Hi Fred,

What do you mean? Can you please elaborate?

Thanks,

If I do a recursive grep search of the streamlit-nightly source code for all strings prefaced by experimental_ or beta_, is that a reliable way of generating a list of all currently available experimental and beta features?

I’ve not tested grep search on the streamlit-nightly source code, but I’d say so! :slight_smile:

Thanks,
Charly

As long as there are no secretly phrased or encrypted methods, I would expect it to!
