Verify inputs against a recorded manifest — hf_verify

Re-fingerprints the files a manifest names and reports each as ok, changed (the hash differs) or missing. Use it before a rebuild to establish that the inputs are the ones a previous result came from.

Usage

hf_verify_manifest(manifest, strict = FALSE)

Arguments

manifest: Path to a manifest written by hf_input_manifest(), or the data frame it returned.
strict: If TRUE, any file that changed or went missing raises an error. Default FALSE reports and returns.

Value

A data frame with role, path, status, and the recorded and current hashes. Returned invisibly when everything matches.

Examples

f <- tempfile(); writeLines("x", f)
m <- hf_input_manifest(reference = f)
hf_verify_manifest(m)
#> [manifest] ok       reference        file1fed165cc17f
#> [manifest] all 1 input(s) match
