Create cff object — cff

Create a cff object from a given source for further manipulation. Similar to cff_write(), but returns a object rather than writing directly to a file. See Examples.

Usage

cff_create(
  x,
  keys = list(),
  cff_version = "1.2.0",
  gh_keywords = TRUE,
  dependencies = TRUE,
  authors_roles = c("aut", "cre")
)

Arguments

x

The source that would be used for generating the cff object. It could be:

A missing value. That would retrieve the DESCRIPTION file on your in-development package.
An existing cff object,
The name of an installed package ("jsonlite"), or
Path to a DESCRIPTION file ("*/DESCRIPTION*").

keys

List of additional keys to add to the cff object. See Details.

cff_version

The Citation File Format schema version that the CITATION.cff file adheres to for providing the citation metadata.

gh_keywords

Logical TRUE/FALSE. If the package is hosted on GitHub, would you like to add the repo topics as keywords?

dependencies

Logical TRUE/FALSE. Would you like to add the of your package to the reference key?

authors_roles

Roles to be considered as authors of the package when generating the CITATION.cff file. See Details.

Value

A cff list object.

Details

It is possible to add additional keys not detected by cff_create() using the keys argument. A list of valid keys can be retrieved with cff_schema_keys().

Please refer to Guide to Citation File Format schema version 1.2.0. for additional details.

If x is a path to a DESCRIPTION file or inst/CITATION, is not present on your package, cffr would auto-generate a preferred-citation key using the information provided on that file.

By default, only persons whose role in the DESCRIPTION file of the package is author ("aut") or maintainer ("cre") are considered to be authors of the package. The default setting can be controlled via the authors_roles parameter. See Details on utils::person() to get additional insights on person roles.
