onetime_been_done: Check if a onetime call has already been made

In onetime: Run Code Only Once

Check if a onetime call has already been made

Description

Check if a onetime call has already been made

Usage

onetime_been_done(
  id = deprecate_calling_package(),
  path = default_lockfile_dir(),
  expiry = NULL
)

Arguments

id	Unique ID string. If this is unset, the name of the calling package will be used. Since onetime 0.2.0, not setting id is deprecated.
path	Directory to store lockfiles. The default uses a unique directory corresponding to the calling package, beneath rappdirs::user_config_dir(). Normally you should leave this as the default.
expiry	difftime() or e.g. lubridate::duration() object. After this length of time, code will be run again.

Value

TRUE if the call has been recorded (within the expiry time, if given).

Examples

oo <- options(onetime.dir = tempdir(check = TRUE))
id <- sample(10000L, 1)
onetime_been_done(id = id)
onetime_message("Creating an ID",  id = id)
onetime_been_done(id = id)

onetime_reset(id = id)
options(oo)
