Read progress.

Source: R/tar_progress.R
tar_progress.Rd

Read a project's target progress data for the most recent run of tar_make() or similar. Only the most recent record is shown.

Usage

tar_progress(
  names = NULL,
  fields = "progress",
  store = targets::tar_config_get("store")
)

Arguments

names

Optional, names of the targets. If supplied, tar_progress() only returns progress information on these targets. You can supply symbols or tidyselect helpers like any_of() and starts_with().

fields

Optional, names of progress data columns to read. Set to NULL to read all fields.

store

Character of length 1, path to the targets data store. Defaults to tar_config_get("store"), which in turn defaults to _targets/. When you set this argument, the value of tar_config_get("store") is temporarily changed for the current function call. See tar_config_get() and tar_config_set() for details about how to set the data store path persistently for a project.

Value

A data frame with one row per target and the following columns:

  • name: name of the target.

  • type: type of target: "stem" for non-branching targets, "pattern" for dynamically branching targets, and "branch" for dynamic branches.

  • parent: name of the target's parent. For branches, this is the name of the associated pattern. For other targets, the pattern is just itself.

  • branches: number of dynamic branches of a pattern. 0 for non-patterns.

  • progress: the most recent progress update of that target. Could be "started", "built", "skipped", "canceled", or "errored".

Examples

if (identical(Sys.getenv("TAR_EXAMPLES"), "true")) { # for CRAN
tar_dir({ # tar_dir() runs code from a temp dir for CRAN.

  list(
    tar_target(x, seq_len(2)),
    tar_target(y, 2 * x, pattern = map(x))
  )
}, ask = FALSE)
