Closes #1643
We discourage nested projects, but it is possible, mostly for developers. So we should at least behave correctly in this code path.
Previously, a nested project would put the name of the parent project in DESCRIPTION, which causes a variety of downstream problems. The
.Rproj
file gets the wrong name. Every call toproject_name()
returns the wrong name.Also, when
proj_set(force = TRUE)
, we should bypass the initial early return if we discover that we are already in a project. The whole point offorce = TRUE
is to do exactly as we are told. This was causing the active project to be still be set to the parent, when trying to work with a nested project.
