onetime_been_done {onetime}

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)
