Identify the called targets function.
Get the name of the currently running targets
interface function. Returns NULL if not invoked inside
a target or _targets.R (i.e. if not directly invoked
by tar_make(), tar_visnetwork(), etc.).
tar_call()
Character of length 1, name of the currently running targets
interface function. For example, suppose you have a call to
tar_call() inside a target or _targets.R. Then if you run
tar_make(), tar_call() will return "tar_make".

if (identical(Sys.getenv("TAR_EXAMPLES"), "true")) {
tar_dir({ # tar_dir() runs code from a temporary directory.
tar_call() # NULL
tar_script({
message("called function: ", tar_call())
tar_target(x, tar_call())
})
tar_manifest() # prints "called function: tar_manifest"
tar_make() # prints "called function: tar_make"
tar_read(x) # "tar_make"
})
