Hello all,

One thing that had been bugging me was the inability to have an
ordered list of the form:

a.  Item 1
b.  Item 2
c.  Item 3

The following patch enables this, with lists going from a-z and A-Z.
Let me know if there are any issues with it.

Thanks,
Nathaniel Flath

I think patches with MIME type application/octet-stream will not make it
into the patchwork server. Please resend the patch with MIME type set to
one of the following:

    text/plain
    text/x-patch
    text/x-diff

as David indicated in

    http://thread.gmane.org/gmane.emacs.orgmode/25513/focus=25560

I think just including the patch in the mail message also works.

Thanks,
Nick

Right, application/octet-stream isn't catched (for good reasons).  So
here's the patch properly attachet as text/plain.

If I understand well your patch, I see a couple of issues with it,
that should not be hard to correct.

- you removed the code allowing to use [@start:number] in a list;
  
- even if you recognize a. and A. lists, you only reorder from a. to
  z. (bullet start is 1- ?a, not 1- ?A);
  
- what happens when user wants to insert the 27th item in his
  alphabetically ordered list ? In other words you should have a
  function to increment such list from z. to aa.

Regards,

-- Nicolas

Hi,

I am not really sure we need these.  They cause problems when lists get
really long - also you patch does not further than "z", after that I  
get "{".

Furthermore the export backends implement their own numbering
rules anyway.  So it seems to me that we do not need this addition.

Any other votes here?

I'm not currently missing this feature.  I think it definitely would
have to handle more entries if this was to be included in org-mode.

Maybe going something like

  a.
  b.
  ...
  z.
  aa.
  ab.
  ...
  az.
  ba.
  bb.
  ...
  zz.
  ... and if you really need more entries than that (unlikely) you can
  do
  aaa.
  aab.
  ...
  and just keep going indefinitely.

I agree, that would be nice.

As a practical matter we should consider whether it's worth making a
non-terminating sequence that can be handled by the exporters.  LaTeX's
enumerate package doesn't like going beyond (z):

\documentclass[letterpaper]{article}
\usepackage{enumerate}

\begin{document}
\begin{enumerate}[(z)]
\item
...
\end{document}

The items beyond the 26th are mapped to "()".

Of course there are going to be ways around these issues, but the question
is whether it's desirable enough to implement and maintain that.  Either way
is fine with me--I'm new on the mailing list and haven't done any
development for org-mode yet.

I was going to fix the issues described in the first reply - not
enough items in particular - and resubmit soon.  I got a bit
distracted by finals.  I'll see if I can figure out the export
problem, as well.

Thanks,

Hey,
I gave another shot at this, now that my computer is no longer dead.
I believe it fixes the issues described earlier - let me know of any
feedback.
(Also - I don't know how to get GMail to attach this as anything other
than application/octet-stream, so the text is in the message as well.

Hi everyone,

I would like to know if there are more people interested in this, and  
if there are people who are willing to test this patch, to make sure  
nothing breaks.

Nicolas, can you in particular please take a look at this - I believe  
you earlier said that you saw problems with it.

Thanks!

- Carsten

Sure, I will have a look at it on Sunday. But before testing it, there
is, by design, one thing that seems dangerous to me. Let's consider
the following text:

This is a sentence in a not so short paragraph, ending where it should
not. What is this line supposed to mean for Org? If this is a
recognized as a list, wouldn't this line get wrongly indented?

Regards,

Hello,

I've tried the patch today. There are still some easily-fixed glitches
(like letters not included in org-cycle-list-bullet, or bullets
allowing mixed text and numbers).

But, there is apparently one major drawback, as I said in a previous
post. If the line starts with a word followed by a dot or a
parenthesis, Org will see a bullet there. This is bad news because the
following line will be indented, or a M-RET will delete the word,
replacing it with a) or a.

Regards,

-- Nicolas

Yes, this happens - it's not something that comes up during my normal
usage, so I didn't notice.  Can you think of a way to determine if
this is the case vs. a list is actually wanted?

Unfortunately, I can't see anything clean. This is tricky because
lists are the closest construct to raw text.

My feeling is that we should not apply this patch.  I see how it might  
be
nice to have such lists - but confusion is rather likely in
this case.

Or, alternatively, put it in with an option to turn it on (default  
off, I think).
And maybe we should after all limit it to a single character to avoid  
confusion.
Yes, I do realise that I asked for several characters - but I am  
learning...

I'd be fine with either (or both) of these, and can code it up once we
decide.  I find it unlikely that I'd use an alphabetical list of size
more than 26, which is why I only had one character to begin with.

What will then happen if the user is cycling bullets in a 100+ items
list and hits alphabetic bullets? Besides undoing that move, there's
nothing much that could be done then. Further cycling would become
impossible.

One idea would be to count items before cycling, and skipping
alphabetic bullets for lists above 26 items. It has to be carefully
implemented, as it could get very heavy on computations with large
lists.

Also, inserting new items in an alphabetical list should check if the
27th item has been reached and change bullets back to numbers if
needed.

I'm sure there are others subtleties that I can't think of right now.

Regards,

-- Nicolas

I think it would be appropriate in this case to simply
throw an error and let the user clean up with undo.

We do not want that I agree.

Again we could simply throw an error here and
let the user handle the cleanup.

Nicolas, would you *object* against a patch by Nathaniel that implements
this?  You are Mr lists now, so your green light will be needed.

Kind regards

Certainly, but this still means that any 27+ items list will never be
able to complete a full bullet cycle as the user will have to undo
each time alphabetical bullets are reached. It could perhaps start
again at letter 'a'...

I wouldn't object against it as some people are finding it useful and
as it won't be turned on by default (if I remember correctly).

But I can't help thinking this could lead to unexpected results in
some cases (admittedly less than when alpha bullets could be any size
long).

Sorry for not following this thread closely.

But from what I read, I thought it might be better to have a _command_
to sort existing lists alphabetically?

That way, there is nothing that has to be "turned on" globally, that
could intefere with Org mode's syntax.


Excuse me, if that's of topic or already discussed.

I don't think this is what I had in mind.  What you suggest seems to
apply for bulleted lists, and sorting the titles of those
alphabetically.  I'm trying to implement lists of the form:

  a.  Item 1
  b.  Item 2
  c.  Item 3

That work the same as lists like:

  1.  Item 1
  2.  Item 2
  3.  Item 3

Correct me if I'm misinterpreting you.

Thanks,
Nathaniel Flath

Ok, we could force the list to become numbered when someone tries to  
cycle it into
a,b,...  THis does not mean that you'd have to count in advance, you  
could simply
try the renumbering and when stepping over z throw an exception that  
will force the
list to move to the next state which would be numbers.

Yes, we sould not turn it on by default because it might bahave strange
under some circumstances.

It definitely will.

Here is an alternative idea.  Nathaniel, what do you
think about this: We could keep the numbering as we
have it in the Org file, but introduce something like [@a]
in the first item that will convert the numbering
into a,b,... upon export to ASCII, HTML, maybe even LaTeX
(even though I think LaTeX demands some consistency here
and prefers to have the global setup decide how lists work).
Hell, we could even use [@A] for capitals and [@i] and [@I]
for roman numbering :)

Sorry for the late response - got swamped with work for a bit.

I'd much prefer the approach I've been going with, mostly since I
don't usually export my notes and mostly view them in org-mode.  I'll
work on the patch tonight - should send a patch either later tonight
or tomorow.

Thanks,

Hello,

I've noticed a couple of glitches.

First, you are using

  (> 28 (length struct))

to know when to replace letters by numbers. But (length struct)
doesn't always match list length, so it will lead to errors when
outdenting items.

For example, try outdenting, with its subtree, the item marked with
"<<<" in the list below:

  a) etsiun
  b) etsiun
  c) etsiun
  d) etisun
  e) etsiun
  f) etsiun
  g) etsiun
  h) etsiun
  i) etisun
  j) etsiun
  k) etsiun
  l) etsiun
  m) etsiun
  n) etsiun
     a) Outdent me and my children ! <<<
        a) tersiu
        b) etsiru
        c) estiur
        d) etsnriu
        e) etsiun
        f) etiune
        g) etuirsnet
     b) etsiun
  o) etsiun
  p) etsiun
  q) etsiun
  r) etsiun
  s) etsiun

All the lists will be numbered although they could keep alphabetical
bullets.

Another (lesser) problem is coming from the regexp chosen for bullets,
that is "[0-9A-Za-z]+". I would suggest something alike
"\\(\\(?:[0-9]\\)+\\|[A-Za-z]\\)". At the moment, you can set counter
to [@a4] and break you list when applying it.

Regards,

-- Nicolas

Also, even when the alpha lists are turned off, typing

    a)

and pressing M-RET will show that a) is seen as a list bullet.

Thanks for your work, we are getting closer to an acceptable patch.

Hello,

>>>>> Nathaniel Flath writes:

> Are there any further issues? Thanks, Nathaniel Flath

I've quick checked your patch and it looks like it is doing its job.

Two things to note, though:

1. I strongly recommend that `org-list-can-be-alphabetical' should
   make use of non-interactive forms instead of interactive ones. In
   other words, you should use `org-get-beginning-of-list' and
   `org-get-next-item' instead of `org-beginning-of-item-list' and
   `org-next-item'. You can see my note about it in org-list.el at
   line 856.

   If you have the structure of the list, `caadr' on it (or an
   equivalent if you don't like cl.el) will give you a valid top item
   needed by non-interactive forms.

2. Your patch doesn't apply to current git head, you should correct
   the conflict.


Regards,

-- Nicolas

Hello,

>>>>> Nathaniel Flath writes:

Also, as you changed `org-item-beginning-re' into a function, there
are a few places outside org-list.el that need to be modified
accordingly.

And exporters (mainly HTML and DocBook) should be aware of
alphabetical bullets.

I think I've fixed these, although I'm not an expert in the exporting.
 Let me know if there's anything else, or if I screwed up anything
when trying to figure out how to make a git patch(looks like it
worked, though.)

Thanks,
Nathaniel Flath

Hi Nathaniel.  There are a few issues with the commit message in this
patch.

  1. Invalid email address
  2. A list of commits with useless information in it (foo, foo2)
  3. Summary line (Squashed commot of the following:) really isn't
     useful on it's own


The subject line (line 1 of the commit message) should be standalone and
concisely state what the commit is for -- so you don't have to read the
rest unless that interests you.

The body of the commit message is for detailed descriptions of the
change.  You should delete the other squashed commit info since it is
not useful.  Describing what exactly you fixed up in the description
would be preferable to 'fixed alphabetical lists patch'.  6 months from
now nobody (including you) will know what you fixed without actually
reading the patch details.

Regards,
Bernt

I looked at your patch and here is what I've noticed so far:


- There's a bug in `org-cycle-list-bullet' where
  org-list-can-be-alphabetical is called with argument missing.

- In `org-cycle-list-bullet', variable `top' stores list top point,
  make use of it instead of recomputing it.

- There's a typo in `org-list-parse-list' (ogr-looking-at-p instead of
  org-looking-at-p)

- Some parts of the patch are only white-space changes (for example a
  change in `org-list-automatic-rules' but there are others). You
  shouldn't include them, as it is not the purpose of the patch.

  It doesn't help understanding your patch either.

- Why did you remove all code comments about lists in org-docbook.el?

- This is not a bug but are you sure you want to make
  org-item-beginning-re a function? I understand that it permits an
  user changing the value of `org-alphabetical-lists' to avoid
  reloading Org, but it looks like syntax overweight to me.

  I mean, anyone wanting to look for a list item will have to remember
  that it must do a re-search on a function and not a string.

  
Hoping that helps,

Regards,

-- Nicolas

I'm working on your comments, should have another patch in the next day or so.

The only thing I had issue with was the comment about
org-item-beginning-re:  I prefer it as a function for the reasons you
mention, but I'm not particularly attached to this.  Does anyone else
have an opinion?

Thanks,
Nathaniel Flath

Sory for the long delay - I got caught up in other work.

A patchaddressing the sisues brought up is attached.

Let me know of anything else.

Thanks,

Subject: [PATCH] Added support for alphabetical patches to org-list.
 Support can be enabled with the 'org-alphabetical-lists' variable, and the numeration goes from 'a' to 'z'.  The latex, html, and docbook exporters have been updated to use these.

Hello,

I've had a look at your patch.

I think the modifications to HTML and DocBook exporters are nice. It
could be possible to do the same thing in LaTeX, but it would require
yet another package (enumitem) by default. Anyway, here are the code
comments :

- in your patch, you should try to list modifications to the
  functions, and which functions were created. For example :

  * org-list.el (org-alphabetical-lists): new variable
  (org-cycle-list-bullet): added "A)" "a)" "A." and "a." to the list
  of bullets in cycle. None of them is allowed in a description list.

- The "yes" at the beginning of org-docbook.el should be removed

- I advise against using (org-next-item) programmatically. It means
  you compute the structure associated to the list for each item in
  the list. I left a note about this circa line 847 in org-list.el

- There's a bug with the following situation :

  A) test
  B) tersi
  C) teirsu
  D) tersiu
  E) tesiu
  F) teisru
  G) etisu
     - sub-item 1
     - sub-item 2
     - sub-item 3
     - sub-item 4
  H) tesinu
  I) tesinru
  J) etnrsiu
  K) tesriun
  L) etnsiu
  M) estinu
  N) etsniu
  O) etsinu
  P) tesnu
  Q) etsinu
  R) etsiun
  S) etsnriu
  T) etsnriu
  U) etsinu
  V) etsiu
  W) etinrsu
  X) last item

  If you outdent sub-items 2 to 4 at the same time (with a region),
  bullet of the last item will become "AA)" and will not be recognized
  as a list item anymore.

- There's also a bug with counters:

  * [0/0] Counter

    A. [X] first box
    B. [X] second box

  These boxes are not counted when bullets are literals (try C-c #).


HTH,

Regards,

Subject: [PATCH] Added support for alphabetical patches to org-list.
 Support can be enabled with the 'org-alphabetical-lists' variable, and
 the numeration goes from 'a' to 'z'.  The latex, html, and docbook exporters
 have been updated to use these.

* org-capture.el: (org-capture-place-item): changed use of variable org-item-beginning-re to be a function call.
* org-docbook.el: (org-export-as-docbook): changed to export alphabetical lists
* org-exp.el: (org-export-mark-list-ending): changed variable use of org-item-beginning-re to be function call.
* org-html.el: (org-export-as-html): changed to export alphabetical lists
* org-latex.el: (org-export-latex-lists): changed variable use of org-item-beginning-re to be a function call.
* org-list.el:
  org-alphabetical-lists: new variable to control whether to use alphabetical lists(defaults nil)
  (org-item-re): converted to use correct regex for alphabetical lists if enabled
  (org-item-beginning-re): converted from a variable to a function
  (org-list-in-item-p-with-indent), (org-toggle-checkbox),(org-list-in-item-p-with-regexp), (org-list-top-point-with-regexp), (org-list-struct), (org-list-get-item-same-level), (org-get-item-beginning), (org-end-of-item-or-at-child), (org-list-first-item-p), (org-list-indent-item-generic): converted use of org-item-beginning-re to a function

  (org-list-at-regexp-after-bullet-p), (org-update-checkbox-count), (org-list-parse-list), (org-list-insert-item-generic), org-list-struct-assoc-at-point), (org-list-struct-fix-bul): corrected regexp to allow for alphabetical lists

  (org-increment-string), (org--convert-alpha-str-to-num), (org-convert-num-toalpha-str): new functions used to increment a bullet in an alphabetical list

  (org-list-can-be-alphabetical): new function that returns 't' if a list can be alphabetical( <27 items)

  (org-list-bullet-inc-maybe): modified to support alphabetical bullets as well as numeric ones

  (org-cycle-list-bullet): modified to also cycle into both capital and lowercas alphabetical bullets, if possible
