Adds a req(FALSE, cancelOutput="progress") which behaves similarly to
cancelOutput=TRUE, but also keeps the output in .recalculating state
even across flush cycles. This is called "persistent progress" and an
output can leave this state when it is invalidated again and doesn't
call req(FALSE, cancelOutput="progress") during that flush cycle.
This will be useful for implementing long-running tasks that don't
hold up the flush cycle, leaving sessions responsive to do other
tasks.
Added an empty option to `choices` in `selectizeInput` in order to make the second `need` statement in `validate` meaningful. Otherwise the second `need` ("Please choose a state") is never displayed.
* Allow trailing commas in more places
I grepped for list(...) and replaced with rlang::list2(...). This also enables !!! which is generally not important for Shiny because it automatically splices lists/tagLists, but I doubt it will affect any existing code.
* update news; no need to rlang::
* missed one
* Update NEWS.md
