Reorder fields using bibtex-mode

Question

I would like to clean up BibTeX entries so that fields always appear in the same order.

For example, I would like the order of fields to always be: author, year, title, journal. So, pressing C-c C-q on:

@Article{Smit90,
  title = {The Title},
  year = 1990,    
  author = {Smith, J.},
  journal = {The Journal}
}

Should produce:

@Article{Smit90,
  author = {Smith, J.},
  year = 1990,    
  title = {The Title},
  journal = {The Journal}

}

bibtex-mode has many options to reformat and clean up fields (see http://www.jonathanleroux.org/bibtex-mode.html#0620), but does not seem to have a way to reorder fields. Ideally, the order of fields should be controlled from bibtex-entry-format and follow the order of fields that is defined in bibtex-BibTeX-entry-alist.

How could this be done?

Answer 1

You have to add sort-fields to bibtex-entry-format.
