Function: bibtex-clean-entry

bibtex-clean-entry is an interactive and byte-compiled function defined in bibtex.el.gz.

Signature

(bibtex-clean-entry &optional NEW-KEY CALLED-BY-REFORMAT)

Documentation

Finish editing the current BibTeX entry and clean it up.

Check that no required fields are empty and format entry dependent on the value of bibtex-entry-format. If the reference key of the entry is empty or a prefix argument is given, calculate a new reference key. (Note: this works only if fields in entry begin on separate lines prior to calling bibtex-clean-entry or if
'realign is contained in bibtex-entry-format.)
Don't call bibtex-clean-entry on @Preamble entries. At end of the cleaning process, the functions in bibtex-clean-entry-hook are called with region narrowed to entry.

Probably introduced at or before Emacs version 19.29.
