Ark: Completions should be sensitive to the text on the RHS of the cursor

[lionel-]

From https://github.com/posit-dev/positron-beta/discussions/47

I think that's annoying enough, and probably not too hard to fix, we'd want to add that to public beta?

Is this a completions issue that should get added to https://github.com/posit-dev/positron/issues/1603?

[lionel-]

I've just added it

Relatedly, @hadley notes:

can completions use text to the right of the cursor as well as text to the left? i.e. I type build_articles() which doesn’t work because I haven’t loaded pkgdown. So I press up, then cmd + left arrow and type pkgdown:: — that then autocompletes to pkgdown::as_pkgdown()build_articles()

Is this related to this? Or should I open a new issue.

If I attempt to complete in this state (to the left of brackets

and I accept the completion suggestion. This gets inserted

Also,I can't see help text for parameters on hovering

i.e. try to see the docs for the path argument here.

Also, when pressing F1 at that location, I get the info message <No R help available at this location>

We are tracking the extra parentheses being added here: https://github.com/posit-dev/positron/issues/4441

I'm not sure we do have anything about the behavior of F1 inside parentheses, so that would be a new issue but I do notice that RStudio also doesn't bring up Help in that situation.

Can be verified once .ps.ark.version() in R Console reports that ark is at 0.1.193 or above.
