Status of the targets (Git)

Source: R/tar_git_status_targets.R
tar_git_status_targets.Rd

Show which targets are outdated.

Usage

tar_git_status_targets(
  script = targets::tar_config_get("script"),
  store = targets::tar_config_get("store"),
  reporter = targets::tar_config_get("reporter_outdated"),
  envir = parent.frame(),
  callr_function = callr::r,
  callr_arguments = NULL
)

Arguments

script

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

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.

reporter

Character of length 1, name of the reporter to user. Controls how messages are printed as targets are checked. Choices:

  • "silent": print nothing.

  • "forecast": print running totals of the checked and outdated targets found so far.

envir

An environment, where to run the target R script (default: _targets.R) if callr_function is NULL. Ignored if callr_function is anything other than NULL. callr_function should only be NULL for debugging and testing purposes, not for serious runs of a pipeline, etc.

The envir argument of tar_make() and related functions always overrides the current value of tar_option_get("envir") in the current R session just before running the target script file, so whenever you need to set an alternative envir, you should always set it with tar_option_set() from within the target script file. In other words, if you call tar_option_set(envir = envir1) in an interactive session and then tar_make(envir = envir2, callr_function = NULL), then envir2 will be used.

callr_function

A function from callr to start a fresh clean R process to do the work. Set to NULL to run in the current session instead of an external process (but restart your R session just before you do in order to clear debris out of the global environment). callr_function needs to be NULL for interactive debugging, e.g. tar_option_set(debug = "your_target"). However, callr_function should not be NULL for serious reproducible work.

callr_arguments

A list of arguments to callr_function.

Value

A tibble with the names of outdated targets.

Details

This function has prettier output than targets::tar_outdated(), and it mainly serves tar_git_status().
