Feature request: spinner only

[lsorber]

Would be great to be able to render alive-progress's spinners only, similar to click-spinner's:

with click_spinner.spinner():
    do_something()
    do_something_else()

Possibly related: #56

In unknown mode, there is currently no way to disable either the unknown bar and/or the spinner. It's very distracting to show two animations in the unknown mode when only one of the animations is enough. If we're able to show only one animation (unknown or spinner), it would look more professional.

Solution in 2.0:

Now there's support for both spinner=None and bar=None, as well as a new config option receipt_text=False. You can just set it to True to print it into the receipt. I preferred a positive logic: when it is True, then Yes it shows, instead of a clear, which when it is True, then No it not shows.

Would v2.0 also allow you to render the spinner at the current cursor position (i.e. without printing a newline)?

I'm not sure, you'd have to wait for the maintainer's response.

Hey, @lsorber, you can! This was first requested in #40. At least you will, as soon as I release #51...

Thanks @TheTechRobo, I appreciate your help in several tickets! 👍

This should also interest @engineerjoe440! I just implemented support for disabling:

• the monitor widget! => the part that shows where you are, "x/y [z%]" for example
• the stats widget! => the part that tracks speed, "(x/s, eta: ys)" for example
• the elapsed widget! => of course the "in xs"

How cool is that!?! 🎉

So in the next 2.0, you will get to do:

Or even something like this:

I think this is not possible "as you say". I cannot read the current cursor position, to reposition it there afterwards. But as I've shown above, you could set a title with any text you want, and draw the spinner besides it. Oh, using the bar.text(), you could also set any text after the spinner!

So you can customize both before and after the spinner, without ever printing a newline 👍

Hey, to simulate exactly what click-spinner does, you just:

I couldn't resist 😂

Remember all the other bells and whistles of alive-progress are active, like hide cursor support, which the other doesn't have...

Looks great, thank you @rsalmei! (Apologies I didn't search before submitting this issue.)

No problem man!
