Trouble with autofill mode

Trouble with autofill mode

[Vikas Rawal]

I am inserting LaTeX \index{} commands in an org document to create an index. Almost everything works fine. But I am having trouble with auto-fill-mode. It often puts a line break in the middle of an index entry, and then it does not work. 

That is, \index{my name} is sometimes broken into \index{my
name}. This creates a problem for LaTeX.

I have disabled auto-fill-mode for now, but that is clearly a sub-optimal thing to do. Is there a way to tell it not to put line breaks in the middle of \index{} entries?

Have you tried

 #+INDEX: my name

I am sorry for not being clear. \index{} may have to be used inline in a para since the index has to pick up the right page where a term appears. So you want to put it as close as possible to the keywords.

Thanks very much. This should work. Let me try to modify it to my use case.

Much appreciated.

This is turning out to be non-trivial for my limited knowledge of regex. We need a regex that would return true for all white spaces between  "\index{" and “}" in a string like

\index{this is an index} and then some text \index(and then another index}

And then add-hook it to 'fill-nobreak-predicate.

Various things that I have tried since yesterday did not get me anywhere.

So put it as close as possible to the keywords:

--8<---------------cut here---------------start------------->8---
This section needs to index some
#+INDEX: multi word term
multi word terms.
--8<---------------cut here---------------end--------------->8---

Yes, I did not think one could put them in the middle of text like this. This should be fine except that having lots of these in the middle of paragraphs would make the text much more difficult to read. But I guess one has to have some compromise somewhere :)

Thanks and cheers.

Another compromise would be to stop using autofill mode and use visual-line-mode or something else. I recently made the switch after many years of auto-fill. It takes a bit of getting used to, but it works well.

  -k.

Yes, I have been thinking about this too. visual-line-mode with each sentence in a separate line would have many other advantages too. It would perhaps be better for git-like version control of documents written in orgmode. Isn’t it?

Do others have an experience to share about this?

Re: Trouble with autofill mode

[John Kitchin]

I turned off auto-fill everywhere many years ago (it messed up my code
blocks in org-mode too much. I usually write them in org-mode, not the
programming mode). I use (global-visual-line-mode 1)

I cannot think of any issues that causes. I even have an
unfill-paragraph to fix what my students do ;) I cannot say I seen many
advantages with git with this, but we usually have one paragraph on a
line.  One day I just need to learn how to do word-based diffs/merge for
text, instead of line-based.

The only exception to auto-fill i can think of is in mu4e, where emails to get filled
so they fit in about an 80 character field.

For org documents, I switched to visual-line-mode and org-indent mode a
while back now after *years* using auto-fill.  Visual-line-mode without
org-indent is less æsthetically pleasing, I find.

I typically have one paragraph per line and this works well.  It may be
less efficient with respect to revision control, e.g. git, but the
efficiency loss is minimal in my opinion.

For LaTeX directives that I used to always put in #+latex: lines when I
needed these within a paragraph, I now increasingly use @@latex:...@@.

The only issue is working with wide tables.  For this, I do have a key
binding to toggle visual-line-mode on and off to make it easier to work
with tables.  It would be nice if somehow org knew not to allow
visual-line-mode to wrap tables but I would imagine this would be
difficult if not impossible.

For emails, I continue to use auto-fill-mode however.

Re: Trouble with autofill mode

I would have thought something like this would work:
(defun nobreak-p ()
  (interactive)
  (let ((result (if (and (looking-at " ")
                         (save-excursion
                           (re-search-forward "[^{]*}" (line-end-position) 'end))
                         (save-excursion
                           (re-search-backward "[^}]*\\\\index{" (line-beginning-position) 'end)))
                    t
                  nil)))
    (message "%s" result)
    result))

(add-hook 'fill-nobreak-predicate #'nobreak-p)

at least, from what I can see it returns true everywhere it should not
break, but I still get breaks where I do not want them. maybe it could
give you an idea though.

FYI, you could make it smelt to just @@l:...@@ with:

--8<---------------cut here---------------start------------->8---
    (add-to-list 'org-export-snippet-translation-alist
                 '("l" . "latex"))
--8<---------------cut here---------------end--------------->8---

Cute!  Org has something for everything. :-)  Thanks.

(mind you, pabbrev means that typing @@l TAB usually gives me what I want!)
