Depends on how much customization you are willing to go through: there is an
enumerate.sty package in LaTeX that can do that:

--8<---------------cut here---------------start------------->8---
...
\usepackage{enumerate}
...
\begin{enumerate}[(1)]
\item foo
\item bar
\end{enumerate}
...
--8<---------------cut here---------------start------------->8---

Inserting the \usepackage from the org file is no problem:

--8<---------------cut here---------------end--------------->8---
#+LATEX_HEADER: \usepackage{enumerate}
...
--8<---------------cut here---------------end--------------->8---


Getting the argument to the enumerate environment in the right place is
another matter. I think the only way is to redefine org-list-generic-to-latex
like this (add this to your initialization file, .emacs or whatever, after you
load org):

--8<---------------cut here---------------start------------->8---
(require 'org-list)

(defun org-list-to-latex (list &optional params)
  "Convert LIST into a LaTeX list.
LIST is as returned by `org-list-parse-list'.  PARAMS is a property list
with overruling parameters for `org-list-to-generic'."
  (org-list-to-generic
   list
   (org-combine-plists
    '(:splice nil :ostart "\\begin{enumerate}[(1)]\n" :oend "\\end{enumerate}"
	       :ustart "\\begin{itemize}\n" :uend "\\end{itemize}"
	       :dstart "\\begin{description}\n" :dend "\\end{description}"
	       :dtstart "[" :dtend "] "
	       :istart "\\item " :iend "\n"
	       :icount (let ((enum (nth depth '("i" "ii" "iii" "iv"))))
			 (if enum
			     ;; LaTeX increments counter just before
			     ;; using it, so set it to the desired
			     ;; value, minus one.
			     (format "\\setcounter{enum%s}{%s}\n\\item "
				     enum (1- counter))
			   "\\item "))
	       :csep "\n"
	       :cbon "\\texttt{[X]}" :cboff "\\texttt{[ ]}"
	       :cbtrans "$\\boxminus$")
    params)))
--8<---------------cut here---------------end--------------->8---

The only change is the definition of :ostart. Not a very flexible method, 
but it will serve in a pinch. ngz et al. might have better ideas.

I should say that there are other ways to customize enumeration labels
in LaTeX - see e.g. http://www.tex.ac.uk/cgi-bin/texfaq2html?label=enumerate -
but afaict they would all require some rewiring of the above function, similar
to the above.

Re: How to get numbered lists (1), (2), … ?

[Marius Hofert]

Dear Nick,

thanks for helping. 

What do you mean by "better solution"? As far as I can tell, your approach is precisely what Suvayu pointed to. Using your approach, of course much more is possible, please look at the create "enumitem" package with all its customizations. 

But this approach is a no-go for me (at least at the moment) mainly due to the following reasons (please let me know if I'm wrong, I'm a total newbie to org-mode):
1) I have about 40 lists in one file. Having to put in special LaTeX commands is not an option (maybe on only has to type it in once, but then it can easily get overseen, e.g., when you move lists around and the one containing the LaTeX commands is not the first one in the document anymore)
2) org-mode is basically a "better" text-mode. I don't want to have LaTeX code in there if I print it as a .txt file.

Is there a solution without having to put
#+LATEX_HEADER: \usepackage{enumerate}
before each list? Can this be set anywhere in the preferences? 

But I assume that I still have to put in lists in org-mode like this: 1.,2.,... or 1),2),... and can't put them in like this (1),(2),...?
Hmm... this is indeed a drawback. The latter lists a far better visible, they are more consistent with respect to other list types such as (i), (ii), etc., and ultimately also with respect to numbering of equations. There are probably even more typographic reasons to display lists like this. For example, if you refer to a list within a theorem environment (which has a label itself) and you use 1., 2.,... lists, then this looks like this:
Theorem 1.2 2. shows that ...
The eye hardly sees that one means Theorem 1.2 Part (2). Even worse, when reading this, one thinks that the sentence stops after "2.". It's really a bad thing, and not getting much better with right-sided parentheses. 

Cheers,

Marius

No: what Suvayu pointed to can be done with the standard latex exporter,
so it would not require changes to org-list-generic-to-latex. Just add
something like this at the top of your org file:

#+LATEX: \renewcommand{\theenumi}{(\arabic{enumi})}

It's better in that it is simpler. There are drawbacks however: the
above produces lists like this:

(1). foo
(2). bar

with a period after the closing paren.

That is true: which one is "better" depends on one's requirements (both
the desired output and how much pain one is willing to suffer in order
to get there).

That's no problem: the LATEX_HEADER line goes in once at the top
of the org file. You can move lists around at will.

You can customize the latex preamble that org adds to latex files to do
that. The disadvantage is that you get the modified preamble always.
See the org-export-latex-packages-alist variable for one way to do that.

> But I assume that I still have to put in lists in org-mode like this:

Correct: that would require changes to org-list.el I think - but Nicolas
will have to say the final word on this. All the solutions so far work
by modifying the latex output only, not the way you enter the list into
the org file.

- On the Org part:

  I have nothing against (1) as item bullets, as it doesn't interfere
  with any existing Org syntax. I just think it shouldn't be available
  by default (much like alphabetical ordered lists).

  The implementation isn't hard /per se/ (at least less changes are
  required than implementing, for example, roman numbered lists), but
  I also think there should be some cleanup with regards to item
  bullets. So far, there is `org-plain-list-ordered-item-terminator' and
  `org-alphabetical-lists' to tweak them. We should avoid adding a third
  one.

  What about letting go those two variables and create
  `org-list-bullet-types', which would be a list of strings like:

           '("-" "+" "*" "1." "1)" "(1)" "a." "a)" "A)" "A.")

  It would be hard-coded but every bullet type could be opt-in or
  opt-out via customize. The default value should be as short as
  possible like '("-" "+" "*" "1." "a.").

  I can work it out in a few days if we agree.

- On the LaTeX part:

  Most of the time, it's better to let LaTeX choose its bullets than
  enforcing code produced to mimic Org buffer. In other words, a "(1)"
  bullet should only mean "enumerate item" instead of "enumerate item
  like (1)".

  Though, in the past months, I have been working on a overhaul of the
  whole export system (as a part of a bigger project). If I ever finish
  it, and if it ever hits Org core, the LaTeX back-end should make it
  easier to use "inparaenum" and "paraitem" packages directly from Org
  syntax (via #+attr_latex header).

  For now, I think solutions offered in this thread are sufficient, if
  not practical.

What percentage of users (OK, not percentage of users but numbers of
users) you think will *actually* exercise the opt-in and opt-out
configuration if provided?

If the number of hands raised is in single digits, I would assume that
it is more of a niche feature and let go of it.

Is it psychologically very taxing to see 1. instead of a (1) in an Org
buffer. Could it be so taxing that a user's productivity will be
impacted by it?

Or 

Is it that more varieties of bullets is needed for creating "rich"
deeply nested lists so that each level of the list can take on a
different bullet for better differentiation.

For my personal use I don't care much as long as there are
ordered/enumerated and unordered/plain lists to choose from, after all
only the exported file is for public consumption. :) However I
strongly feel _against_ the '*' syntax. Its too close to a headline.
It is also unusable if one chooses not to use indentation for the text
under a headline (e.g. below). I often prefer this as deeply nested
(say, level 4) headlines often start to run out of columns due to
wrapping.

** Heading

Some list
* list item 1
* list item 2

This is pretty much the reason I switch list types. Something like:

1) some broad point
   + Case 1
     - comment on something of note
   + Case 2
2) another broad point

That said, I would probably use the customize option.

[Marius Hofert]

Hi all,

I am quite impressed by this discussion, thanks a lot.
I am an org-mode user for just a couple of days, and an emacs user for four weeks today. Needless to say, I can't contribute anything useful to this discussion. 
The only thing(s) I would like to say is/are:
(1) If it is not too complicated from a technical point of view, I would strongly recommend to enable lists like (1), (2), etc.  I gave some reasons in one of my earlier e-mails in this thread. There are many more (from a typography point of view, but also from a technical point of view [e.g., if you have auto-pairing of parentheses enabled, it's just more convenient.]). 
(2) From a LaTeX point of view, I am sure the experts here (and I mean everyone in this thread except me) know the LaTeX package "enumitem". It gives the greatest flexibility of creating lists I know of and behaves better in many circumstances than other enumerate-like environments. So I can only recommend using this approach for making lists (in which way this is possible/desirable I can't tell since I'm not an org-mode expert).

I will certainly become a heavy org-mode user in the next months/years. Lists like (1), (2),... I would definitely use a lot.

Cheers,

Marius

That is not the only criterion.  Adding new syntax elements make more
ASCII sequences special.  The Org markup is a heuristic set of
special elements, and there is merrit in keeping it small.  We already
have more bullets and in particular numbered types - and so far
I have not seen a compelling reason to add more.

I am in the "keep it simple school".  So long as org allows me to
distinguish between numbered and unnumbered itemised lists, I am
happy.  I actually would prefer less choices than there are currently
because I would like to get to my choice more quickly when I do use
C-c - to change the type!

To me, org is about information and time management, not about
formatting.  YMMV, of course!

To be blunt, I would be happy with "-" and "1." in org, knowing that I
can customise upon export if necessary!  I'm not suggesting we go this
far, however ;-)

I'm 100% with Eric, just that I would say "-" and "(1)" are enough.

You can switch (a little faster) with S-right and S-left arrows anywhere
on the list item.

Since backward compatibility is necessary, this counts as a vote for a
customizable sequence, as proposed by Nicolas, do I see this right?

So maybe this *is* a good idea, but I would be agains adding new list types.

I guess I was voting without realising that I was ;-)  I'm happy with
things as they are but definitely would have no problem with a
customisable list, one that I would tend to shorten!

Without diving into how to set it up in org-mode, the paralist package for
LaTeX enables inline numbered lists, as in

%% In preamble
\usepackage{paralist}


%% In document
\begin{inparaenum}
   \item first element
  \item second element
\end{inparaenum}

As to how to organize this to be an option for org-mode without
incorporating above into the setup, I would also be interested.

The method described below can of course accomplish this: you need to
change the :ostart and :oend settings. It's also fairly easy to define
customizable variables for all of this, but that is left as an exercise
to the interested reader... Nicolas might be interested in anything you
come up with.

Nick

Hint (entirely untested):

(defcustom o-e-l-l-s-ostart "\begin{enumerate}\n" ...)
(defcustom o-e-l-l-s-oend ...)
...

(setq org-export-latex-list-settings `(:splice nil :ostart ,o-e-l-l-s-ostart :oend ,o-e-l-l-s-oend
                                                   :ustart .....)

...[ some way to reevaluate the above variable if any of its components change - does custom provide anything like that?? ]...

(defun org-list-to-latex (...)
   ...
   (org-combine-plists
        org-export-latex-list-settings
        params)
   ...

How to get numbered lists (1), (2), … ?

[Marius Hofert]

Dear all,

In the manual, I found that numbered lists can be created with 1), 2), ... or 1., 2., ...
How can I get numbered lists like this: (1), (2),...?
I found org-list-demote-modify-bullet, but the help (and a google search) did not help me in finding a solution to this.

Cheers,

Marius

I don't think you can. But you can customise latex export (maybe even
html export, but I don't know) to show lists like that in the exported
file.

I hope this helps.

Dear Suvayu,

thanks. 
It would be good to know how latex export can be customized to achieve this.

Cheers,

Marius
