org-mode and longlines-mode (especially tables)

org-mode and longlines-mode (especially tables)

[Mark Aufflick]

Hi Everyone,

I am using longlines-mode with org-mode to do word wrapping. It is
useful in normal view to get wrapping at word boundaries, but it is
especially useful with vertical split windows (C-x 3) since they
default to not wrapping at all.

I have noticed a few wierd issues in org-mode related to the
pseudo-linebreaks managed by longlines mode.

The first issue is not really a big deal - if you are in an org list,
and are at the end of a wrapped line eg looks like:

 + adsf asdf adsf
asdf asdf{cursor here}

and you hit M-Enter, you get a heading of the most recent heading
level, not a new list entry. Presumably org-mode thinks the
longlines-mode soft-newline is a real newline

The second issue is bigger, relating to tables. If you make the first
line of a table and hit tab, eg:

|* col a *|* col b *|{TAB}

You get:

| * col a * | * col b * | |           |           |

so the newline that org-table-mode thinks it is inserting gets gobbled
by longlines-mode, or something like that.

Has anyone else noticed this? Is there a smarter way to get soft-word
wrapping in org-mode without using longlines-mode?

Mark.

I've taken only a brief look at longlines, but I can see not easy way
to make longlines work with org-mode.  Org-mode is strongly based
on plain text format with hard line breaks.

Hey, folks:

I've also been using org-mode with longlines-mode, and had noticed  
that the two occasionally conflict. I've just developed workarounds  
for the bugs that affect me, mostly inserting extra carriage returns  
here and there to ensure the right line breaks for org-mode. Carsten,  
if you have the option of minimizing these conflicts, that would be  
great. Otherwise, I'll just keep doing it manually - these two modes  
are both essential for my work now, so I'll do what it takes to make  
them get along locally.

I think this is really really hard.  Basically, I would have to change
all places where Org-mode inserts newlines that should be hard.

Hmmm, maybe all newlines that org-mode inserts during internal commands 
should be hard?

In this case, a brute-force solution might do the trick.  This is not 
well tested,
but it does make tables work as long as they are not broader than fill 
column:

(defadvice insert (around make-org-mode-newlines-hard activate)
   "Make sure all org-mode functions insert hard newlines."
   (if (and (eq major-mode 'org-mode)
	   (boundp 'longlines-mode) longlines-mode
	   (equal "org-" (substring (symbol-name this-command) 0 4)))
       (let ((_beg (point)))
	ad-do-it
	(longlines-decode-region _beg (point)))
     ad-do-it))

(defadvice insert-before-markers (around make-org-mode-newlines-hard 
activate)
   "Make sure all org-mode functions insert hard newlines."
   (if (and (eq major-mode 'org-mode)
	   (boundp 'longlines-mode) longlines-mode
	   (equal "org-" (substring (symbol-name this-command) 0 4)))
       (let ((_beg (point)))
	ad-do-it
	(longlines-decode-region _beg (point)))
     ad-do-it))

Damn - defadvice is way cool! I do similar AOP-style things in Perl,
but nothing that clean or simple.

Having said that, it doesn't seem effective for me. It compiles fine
(in my .emacs), but there is no change in functionality. I tried with
org-mode 4.6.7 and then upgraded to .9. gnu emacs 22.0.94.1

I'm not familiar with the calling syntax of defadvice, so I'll keep playing.

Thanks very much for the code.

Mark.

Hmmmm, the other day I had a working version, but you are right, what I
posted does not work.  I don't understand yet why - I'll be back about 
this.

Re: org-mode and longlines-mode (especially tables)

[Carsten Dominik]

Turns out you cannot advise insert because the byte-compiler
treats it in a special way.  So this will only work if you do
not compile org.el to org.elc.  If you remove org.elc and also
any internal org.elc Emacs might be distributed with, then the
advice will work - but you have to pay a speed penalty in Org-mode.
