Drop orphaned entries from the nlmixr2targets indirect cache

Removes cache entries whose md5 hash is not in keep. By default dry_run = TRUE, so the function reports what would be removed without actually deleting anything; pass dry_run = FALSE to delete.

Usage

nlmixr2targets_cache_prune(
  keep = NULL,
  dry_run = TRUE,
  directory = file.path(targets::tar_config_get("store"), "user/nlmixr2")
)

Arguments

keep

Character vector of md5 hashes to retain. If NULL (default), the helper auto-discovers reachable hashes from the targets metadata in the current store. Set to character() to treat every cached entry as an orphan.

dry_run

Logical. If TRUE (default), do not delete anything; just return the hashes that would be removed. If FALSE, delete.

directory

Cache directory; same default as nlmixr2targets_cache_status().

Value

Invisibly, a character vector of the orphan hashes (those that were removed when dry_run = FALSE, or would be removed otherwise).

Details

When keep = NULL, the function reads the targets metadata in the current store and treats every value of a built target whose name ends in _object_simple (the hashes produced by nlmixr_object_simplify()) as reachable. Pass an explicit character vector if you want to override that, e.g. before calling targets::tar_destroy() yourself.
