Fetch herald rules from GitHub

Downloads herald validation rules from the herald-rules GitHub repository (https://github.com/vthanik/herald-rules) and caches them locally. Subsequent calls use the local cache unless force = TRUE.

The download is approximately 5 MB (one-time). Rules include CDISC CORE, FDA Validator, PMDA, Controlled Terminology, and herald gap-fill rules.

Usage

fetch_herald_rules(force = FALSE)

Arguments

force

Logical. Re-download even if already cached? Default FALSE.

Value

Path to the local cache directory (invisibly).
