sphinxcontrib-citations 0.2.0

Create a list with all the papers that cite yours

sphinxcontrib-citations

It is often the case that open-source software enables new scientific developments. When this happens, it is desirable to highlight which new results were obtained with a given piece of software. If your project has one or more associated published resources (for example, in the Journal of Open-Source Software, or in Zenodo), you can use sphinxcontrib-citations to generate a page in your documentations that lists the papers that cite your code.

sphinxcontrib-citations is an Sphinx extension that uses NASA's ADS to look up which papers cite a given list of references. sphinxcontrib-citations is currently in a state of minimum-viable-product: the basic features are available, but not much else. Pull request are welcome.

To use sphinxcontrib-citations, first install it and add it to the extensions variable in your conf.py as sphinxcontrib.citations. sphinxcontrib-citations has only three options:

• citations_ads_token: this is the ADS API token, and it required for the correct functioning of the extension. You need a freely obtainable API token to use this package. Read more about NASA ADS API.
• citations_bibcode_list: this is the list of bibcodes for which citations have to be found. You can find the bibcode for a given paper on ADS.
• citations_bibtex_file: this is the name of the .bib file that will be generated. If not specified, it will be sphinxcontrib_citations.bib. If a file with the given path already exists, it will be silently overwritten.

When you compile your documentation, sphinxcontrib-citations will find all the references and create a bib file. Then, sphinxcontrib-citations interfaces with sphinxcontrib-bibtex to produce the page. You can use all the options provided by that package. A simple page might look like:

Papers citing this software
=============================================

.. bibliography:: sphinxcontrib_citations.bib
   :list: enumerated
   :all:

Make sure that the name of the file matches your choice for citations_bibtex_file.

ADS API Token in GitHub actions

Clearly, committing the API token directly to GitHub is not a good idea. GitHub actions support encrypted secrets that can be used to safely store the token.

Assuming you create a repository secret named ADS_API (that contains the token), you can pass it to Sphinx through an environment variable. For instance, the action step might look like:

- name: Produce documentation
  env:
      ADS_API: ${{ secrets.ADS_API }}
  run: |
    make html

with citations_ads_token = os.environ["ADS_API"] in the conf.py.

Example

For an example, see kuibit.

The relevant Sphinx configuration settings that generated this example are:

citations_ads_token = os.environ["ADS_API"]
citations_bibcode_list = ["2021JOSS....6.3099B"]
