bibtex-clean-entry indents badly when splitting long lines

bibtex-clean-entry indents badly when splitting long lines

[Tim Hesterberg]

I have an entry like this in a .bib file:


@Article{turl00,
  author =	{author},
  title = 	{This is a long title that is more than one line long and should be split into multiple lines},
  journal = 	{journal},
  year = 	{year}
}

In emacs 21.3, if I do C-c C-c (bibtex-clean-entry) the result is:

@Article{turl00,
  author =	{author},
  title =	{This is a long title that is more than one line long
                 and should be split into multiple lines},
  journal =	{journal},
  year =	{year}
}

Note that the title line is split into two lines, with indentation
determined by bibtex-contline-indentation, which has the value 17.

In emacs 22.1 the continuation line is indented incorrectly:

@Article{turl00,
  author =	{author},
  title =	{This is a long title that is more than one line long
  and should be split into multiple lines},
  journal =	{journal},
  year =	{year}
}



My .emacs includes:
(setq bibtex-include-OPTcrossref nil)
(setq bibtex-include-OPTkey nil)
(setq bibtex-maintain-sorted-entries t)
(setq bibtex-text-indentation 16)


I tried to debug this.  In case it helps:

In emacs 21.3 the sequence of function calls is:
bibtex-clean-entry
  bibtex-fill-entry
    bibtex-do-auto-fill
      do-auto-fill

In emacs 22.1 the sequence is:
bibtex-clean-entry
  bibtex-fill-entry (this is very different from the emacs 21.3 version)
    bibtex-fill-field-bounds
      fill-region-as-paragraph

I cannot reproduce that.

Both in emacs 21.3 and 22.1 filling of fields is done only if
bibtex-entry-format includes also the option realign, i.e., you need
a line like the folliwng in your .emacs

(setq bibtex-entry-format '(opts-or-alts numerical-fields realign))

When I do that, I get the same filling you got with emacs 21.3.

Have you tried to reproduce the unintended behavior with
"emacs --no-init-file" and evaluating the above BibTeX settings in
the *scratch* buffer? As you noticed, the real work of filling is
now done by fill-region-as-paragraph, whereas emacs 21.3 used
do-auto-fill. Maybe you have some personal customizations that affect
the behavior of these general functions.

Thanks for checking.

My apology - there were some additional relevant things in my .emacs:

(setq bibtex-entry-format '(opts-or-alts required-fields numerical-fields realign last-comma))
(add-hook 'bibtex-mode-hook
	  '(lambda ()
	     (setq fill-prefix nil); prevent C-o from indenting
	     ))

It is setting the fill-prefix to nil that appears to cause this.

I set the fill-prefix to nil to prevent C-o open-line from indenting.
I'll look for another way to do that.
