Build Targets List from Quarto Frontmatter — build_targets

Reads calcofi: YAML frontmatter from all .qmd files in the workflows directory and returns a list() of targets::tar_target() calls suitable for use as the body of _targets.R. Includes a corrections_csv target that tracks metadata/ship_renames.csv and metadata/measurement_type.csv, so any edit to those files forces re-run of dependent ingest targets.

Usage

build_targets_list(
  workflows_dir = here::here(),
  corrections = c("metadata/ship_renames.csv", "metadata/measurement_type.csv"),
  exclude = NULL,
  verbose = TRUE
)

Arguments

workflows_dir: Path to workflows directory (default: here::here())
corrections: Character vector of correction file paths relative to workflows_dir (default: c("metadata/ship_renames.csv", "metadata/measurement_type.csv"))
exclude: Character vector of target names to exclude from the pipeline (default: NULL). Excluded targets are also removed from other targets' dependency lists. Useful for skipping large workflows like "ingest_calcofi_ctd-cast".
verbose: Print parsed workflow table (default: TRUE)

Value

A list() of tar_target() objects ready for _targets.R

Details

Workflows with dependency: [auto] (typically release_database) auto- depend on all targets whose workflow_type is "ingest" or "spatial".

Examples

if (FALSE) { # \dontrun{
# in _targets.R:
library(targets)
devtools::load_all(here::here("../calcofi4db"))
build_targets_list()

# skip CTD ingest:
build_targets_list(exclude = "ingest_calcofi_ctd-cast")
} # }
