Export a justifier specification to JSON

Usage

export_to_json(x, file = NULL, wrap_in_html = FALSE)

# S3 method for justifierStructuredObject
export_to_json(x, file = NULL, wrap_in_html = FALSE)

# S3 method for justifier_json
print(x, ...)

Arguments

x: The justifier specification.
file: Optionally, a file to save the JSON to.
wrap_in_html: Whether to wrap the JSON in an HTML element.
...: Any additional arguments are ignored.

Value

If a file is specified to write, to, x will be returned invisibly to allow building a pipe chain; if file=NULL, the resulting JSON will be returned as a character vector.

Examples

### Programmatically create a justification with two assertions
### but without sources; flatten it; and show the json
justifier::justify(
  "Icecream will make me feel less fit",
  assertion = c(
    justifier::assert('Icecream is rich in energy'),
    justifier::assert('Consuming high-energy foods makes me feel less fit')
  ),
  weight = -.5
) |>
  justifier::flatten() |>
  justifier::export_to_json();
