package::function() autocompletion doesn't include re-exported functions

[francisbarton]

In RStudio, I can use autocomplete to complete function names such as:

purrr::set_names() and rvest::read_html().

These are functions that belong originally to other packages (rlang and xml2 respectively in these examples) but are also exported from purrr and rvest.

In R in VSCode, if I try to autocomplete rvest:: I don't get read_html() as a dropdown option. I can only get it by starting with xml2::. Is there a way that languageserver could read in these borrowed functions as options for autocomplete?

Looks like objects doesn't return the re-exported functions.

r$> "set_names" %in% objects(asNamespace("purrr"))
[1] FALSE

r$> "set_names" %in% getNamespaceExports(asNamespace("purrr"))
[1] TRUE
