Run daggle lint on a DAG — daggle

Shells out to the local daggle CLI to run semantic diagnostics on a DAG (missing scripts, unresolvable secrets, unknown notification channels, and optionally missing R packages). Returns a tidy data.frame of diagnostics.

Usage

daggle_lint(dag, check_packages = FALSE, daggle_bin = "daggle")

Arguments

dag: Character string. DAG name or path to a DAG YAML file.
check_packages: Logical. If TRUE, also verify that R packages required by R-based step types (rmd, coverage, pkgdown, pins, ...) are installed. Slower; runs a single Rscript invocation. Default FALSE.
daggle_bin: Character string. Path to the daggle binary. Defaults to "daggle" (resolved via PATH).

Value

A data.frame with columns path, line, col, severity ("error", "warning", "info"), code, and message. Returns a zero-row data.frame when the DAG passes cleanly.

Details

Requires the daggle binary on the user's PATH.

Examples

if (FALSE) { # \dontrun{
diagnostics <- daggle_lint("etl-pipeline")
stopifnot(nrow(diagnostics[diagnostics$severity == "error", ]) == 0)
} # }
