Subject: bug#36252: 26.1; bibtex-generate-autokey does not use use date field

[Message part 1 (text/plain, inline)]

Package: emacs
Version: 26.1
Tags: patch

The bibtex.el package will automatically generate a key for a BibTeX
entry when required. To do so, it extracts the year from the 'year'
field. Instead of the 'year' field, the biblatex dialect uses the 'date'
field to record the publication date. The bibtex-generate-autokey
function should fallback to the date field when the year field is
absent. This requires a bit of care because the 'date' field can contain
an arbitrary date satisfying the "ISO8601-2 Extended Format
Specification Level 1". Fortunately, a relatively simple regex can
extract the year from all of the examples listed in the biblatex
manual[0].

Please see attached for a patch adding support for the 'date' field.
