Not setting id explicitly is now deprecated with a
warning. Doing this is brittle: it can lead to silent errors when you
use onetime functions in more than one place.
New function onetime_mark_as_done() to manually mark
an action as done.
New function onetime_dir("dirname") returns a path
to an arbitrary subdirectory of the onetime base directory for
lockfiles.
onetime_message_confirm() now prints its message by
default in non-interactive sessions, along with instructions on how to
hide the message using onetime_mark_as_done().
onetime_message_confirm() now passes multiple
arguments to message() using .... This makes
it easier to pass long messages. Using a named message
argument is soft-deprecated.
onetime_only() gains a default argument
which is returned by the wrapper function if the inner function was not
called. The default default is NULL.
onetime_message() and friends all now return their
results invisibly. This is nicer for use in rmarkdown
documents.
onetime_do() now always returns invisibly, even when
default is returned.
onetime_only() now respects the visibility of the
wrapped function.
New vignette.
