Write a CITATION.cff file — cff

This is the core function of the package and likely to be the only one you would need when developing a package.

This function writes out a CITATION.cff file for a given package. This function is basically a wrapper around cff_create() to both create the cff object and writes it out to a YAML-formatted file in one command.

Usage

cff_write(
  x,
  outfile = "CITATION.cff",
  keys = list(),
  cff_version = "1.2.0",
  gh_keywords = TRUE,
  dependencies = TRUE,
  validate = TRUE,
  verbose = TRUE
)

Arguments

x

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

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

outfile

The name and path of the CITATION.cff to be created.

keys

List of additional keys to add to the cff object. See cff_create() for details and examples.

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?

validate

Logical TRUE/FALSE. Should the new file be validated using cff_validate()?

verbose

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

Value

A CITATION.cff file and an (invisible) cff object.

Details

When creating and writing a CITATION.cff for the first time, the function adds "CITATION.cff" to ".Rbuildignore".

Examples

# \donttest{
tmpfile <- tempfile(fileext = ".cff")
cff_obj <- cff_write("jsonlite", outfile = tmpfile)
#> /tmp/RtmpIMm00O/file5a73d1178f5.cff generated
#> 
#> cff_validate results-----
#> Congratulations! This .cff file is valid
