Usage: cffconvert [OPTIONS]

Options:
  -if, --infile TEXT          Path to the CITATION.cff input file.

  -f, --outputformat TEXT     Output format: bibtex|cff|codemeta|endnote|ris|zenodo
  -u, --url TEXT              URL of the repo containing the CITATION.cff (currently only github.com is supported; may
                              include branch name, commit sha, tag name). For example: 'https://github.com/citation-
                              file-format/cff-converter-python' or 'https://github.com/citation-file-format/cff-
                              converter-python/tree/master'
  --validate                  Validate the CITATION.cff found at the URL or supplied through '--infile'
  -ig, --ignore-suspect-keys  If True, ignore any keys from CITATION.cff that are likely out of date, such as
                              'commit', 'date-released', 'doi', and 'version'.
  --verbose                   Provide feedback on what was entered.
  --version                   Print version and exit.
  --help                      Show this message and exit.

Example usage, retrieve CITATION.cff from URL with curl, output as BibTeX:

curl https://raw.githubusercontent.com/citation-file-format/cff-converter-python/44a8ad35d94dd50a8b5924d8d26402ae0d162189/CITATION.cff > CITATION.cff
cffconvert -f bibtex

Results in:

@misc{YourReferenceHere,
author = {
            Jurriaan H. Spaaks and
            Tom Klaver
         },
title  = {cff-converter-python},
month  = {1},
year   = {2018},
doi    = {10.5281/zenodo.1162057},
url    = {https://github.com/citation-file-format/cff-converter-python}
}

Example usage, let cffconvert retrieve CITATION.cff from URL, output as codemeta.json:

cffconvert -f codemeta -u https://github.com/citation-file-format/cff-converter-python/tree/master -of codemeta.json

Contents of file codemeta.json:

Convert the contents of a local file CITATION.cff into the format used by .zenodo.json files (see Zenodo’s API docs), while ignoring any keys that are likely out of date:

cffconvert -f zenodo --ignore-suspect-keys

Results in (note absence of date-released, doi, and version):

{
    "creators": [
        {
            "affiliation": "Netherlands eScience Center",
            "name": "Spaaks, Jurriaan H."

        {
