Support cycling for in completion in region

[clemera]

See #419
@minad I did it a bit differently since in Selectrum we filter the collection only initially with a different style and I would like to keep that behavior. You might want to update the consult version for completion--cycle-threshold as this also checks for possibly defined threshold by metadata.

[minad]

Thank you. I wonder why you want this behavior of filtering initially with a different style. Why does this make sense?

[minad]

I found the discussion in minad/consult#218, reading through this now.

For the completion itself (after invocation) I think it makes sense to use the same styles as usually but the initial filtering is the spot that I would like to be different. I also like the feature of using all-completion for that which makes the initial invocation faster. Also this approach fits better into Selectrum because filtering can be adjusted by other means than completion-styles (for example when using prescient).

[minad]

Okay, thank you for explaining again. I still don't see where I would want this, maybe in combination with Prescient filtering. But I hope Prescient moves to completion styles soon.

[clemera]

I like the speed boost with all-completions and I don't know why there should be different styles afterwards. Having prescient switching to completion styles would be nice, though it kind of seems like a duplicated effort with orderless already present.

Agree. My favorite solution for Prescient would be if it just drops the filtering part, and recommends Orderless instead for filtering.

I suggested that in the past, see the discussion here, maybe it could be reconsidered.
