Download and unpack configured external CraftGRN demo data

Source: R/utils_demo_data.R
download_craftgrn_demo_data.Rd

Downloads a processed demo data archive from a configured external source, verifies its MD5 checksum by default, extracts it, and returns the extracted project directory. Demo bundles are external to the R package so package installation remains small and CRAN-friendly. No external demo bundle is currently configured.

Usage

download_craftgrn_demo_data(
  destdir = ".",
  demo = NULL,
  overwrite = FALSE,
  checksum = TRUE,
  verbose = TRUE
)

Arguments

destdir

Directory where the archive should be downloaded and unpacked.

demo

Optional demo bundle name. No external demo bundle is currently configured.

overwrite

Logical; if `TRUE`, download the archive again and replace an existing extracted project directory.

checksum

Logical; if `TRUE`, verify the downloaded archive MD5.

verbose

Logical; if `TRUE`, emit concise status messages.

Value

The normalized path to the extracted demo project directory.

Details

If the download fails, inspect `craftgrn_demo_data_info()` and download the configured asset manually. If checksum verification fails, rerun with `overwrite = TRUE` to replace a stale or partial archive. The extracted project uses `base_dir: "."`, so pass the returned directory or its project config path directly to package functions after moving the folder.
