Validate whisker data against a template's required tokens

Raises a clear error listing every missing or NA token before whisker or Typst ever run, instead of letting a missing token silently render as blank text.

Usage

validate_template_data(path, data)

Arguments

path

Character. Path to a .typ file.

data

Named list of whisker substitution values.

Value

Invisibly TRUE if validation passes.

Examples

path <- resolve_template("cohort_summary")
required <- extract_required_tokens(path)
# Placeholder values: validate_template_data() only checks presence/
# non-NA, not real content, so this always passes regardless of which
# tokens a given template actually needs.
data <- setNames(as.list(rep("placeholder", length(required))), required)
validate_template_data(path, data)
