tar_meta_download: download local metadata to the cloud.

In targets: Dynamic Function-Oriented 'Make'-Like Declarative Pipelines

download local metadata to the cloud.

Description

download local metadata files to the cloud location (repository, bucket, and prefix) you set in tar_option_set() in ⁠_targets.R⁠.

Usage

tar_meta_download(
  meta = TRUE,
  progress = TRUE,
  process = TRUE,
  crew = TRUE,
  verbose = TRUE,
  strict = FALSE,
  script = targets::tar_config_get("script"),
  store = targets::tar_config_get("store")
)

Arguments

meta	Logical of length 1, whether to process the main metadata file at ⁠_targets/meta/meta⁠.
progress	Logical of length 1, whether to process the progress file at ⁠_targets/meta/progress⁠.
process	Logical of length 1, whether to process the process file at ⁠_targets/meta/process⁠.
crew	Logical of length 1, whether to process the crew file at ⁠_targets/meta/crew⁠. Only exists if running targets with crew.
verbose	Logical of length 1, whether to print informative console messages.
strict	Logical of length 1. TRUE to error out if the file does not exist in the bucket, FALSE to proceed without an error or warning. If strict is FALSE and verbose is TRUE, then an informative message will print to the R console.
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.
