Parse msens: frontmatter from pipeline notebooks — parse_qmd

Globs the .qmd files in workflows_dir, reads the YAML frontmatter of each (the block between the first two --- fences), and keeps only those carrying a top-level msens: key. Returns one row per pipeline notebook with the fields needed to wire the targets DAG.

Usage

parse_qmd_frontmatter(workflows_dir = here::here(), pattern = "*.qmd")

Arguments

workflows_dir: directory holding the pipeline .qmds (default here::here())
pattern: glob for notebooks (default "*.qmd")

Value

a tibble with columns qmd_file, target_name, workflow_type, dependency (list column), output

Details

The msens: block vocabulary:

target_name: the targets node name (a legal R symbol)
workflow_type: one of grid, ingest, merge, score, publish, release, test
dependency: list of upstream target_names, or [auto] to depend on every grid + ingest target
output: the file/dir the notebook produces (tracked via format = "file"; may contain a * glob)

Examples

if (FALSE) { # \dontrun{
wf <- parse_qmd_frontmatter("~/Github/MarineSensitivity/workflows")
dplyr::filter(wf, workflow_type == "ingest")
} # }
