overview

What bibtex-format does

Clean, normalize and deduplicate a BibTeX file with K-Dense's citation-management formatter (canonical field order and alignment, page-range fixes, DOI duplicate removal, optional sort and citation-key rewrite). Offline.

Normalize field order, align equals signs and convert page ranges such as 10-20 to 10--20. Duplicate entries are removed by case-insensitive DOI or identical citation key. Different keys without matching DOIs are retained even when their titles match.

The input limit is 16 MiB. Optional sort accepts key, year, author or title. Rekey defaults to false; enabling it changes citation keys before deduplication and can break existing document citations. Input with no parseable entries fails without output.

Packaged version: 065b734. Upstream license: MIT.

The public image repository gives immutable image and ORAS download commands, the expected source/notices bundle checksum and pinned upstream source directions. The accompanying OCI bundle retains the original build recipe, runtime sources and full installed notices. The Git recipe keeps primary notices and an exact layer/hash index; it does not duplicate the full installed notice tree or mirror every upstream source archive. Image, source and license notice downloads.
