cff_validate {cffr}

Validate a CITATION.cff file or a cff object

Description

Validate a CITATION.cff file or a cff object using the corresponding validation schema.

Usage

cff_validate(x = "CITATION.cff", verbose = TRUE)

Arguments

x

This is expected to be either a full cff object created with cff_create() or the path to a CITATION.cff file to be validated. In the case of a ⁠*cff⁠ file it would read with cff_read_cff_citation().

verbose

Logical TRUE/FALSE. On TRUE the function would display informative messages.

Value

A message indicating the result of the validation and an invisible value TRUE/FALSE. On error, the results would have an attribute "errors" containing the error summary (see Examples and attr()).
