AUCTeX Preview LaTeX didn't work with Org last time I tried, but I'm
not sure whether you're referring to this or Org's preview
capabilities (which lack a bit behind AUCTeX's).

Do try to cut it to a minimum example and use less exotic packages.  I
don't want to install new packages for the sake of trying your
example.

In any case, it's probably a conflict of packages (some functions may
be defined twice).  On my system the files used to generate images are
stored in the root of /tmp (on a GNU/Linux system).

Also, check out the variable org-format-latex-header.

Also, on previewing in general: Do you use org entities?  They make
stuff like this pretty readable.  If you need more readability you can
even create math matrices with Org-tables.

Hope it helps,
Rasmus

You can't. This behaviour is hard-coded.

[O] [bug?][patch] Org LaTeX Fragments

[Rasmus]

Hi,

I don't know if this is a bug or a feature, but consider the following
test file:

#+BEGIN_SRC Org
#+TITLE: Fails when exporting
#+TITLE: Fails when exporting

* Instructions :noexport:

  1. Start =emacs -q=
  2. <> Run \src_emacs-lisp{(org-preview-latex-fragment)}
 - WORKS
  3. <> Run \src_emacs-lisp{(org-latex-export-to-pdf)} =./test.pdf=
 - FAILS

  [[p2]] works when [[p3]] fails because `org-format-latex-header`
  loads =amsmath=, but Org LaTeX export doesn't.  Why I don't know.

  *Proposal: Replace amstext with amsmath.*

* test
\begin{align}
x \mathcal{ABC}
\end{align}
#+END_SRC


The first patch adds amsmath as a dependency which fixes the above
bug.  According to my TeXLive it seems amstext is distributed with
amsmath, so I don't think that's an issue.  Increased load time?
Well, maybe.  I didn't test.

Will amstext be missed?  No, it's loaded by amsmath, currently line 120

 \RequirePackage{amstext}[1995/01/25]

The second patch removes the dependency on eucal.  Eucal provides an
alternative font for the mathcal macro.  Unless someone believes it's
better than the standard font, e.g. for small fonts, there is little
point in requiring it IMO.

We could also replace color with xcolor, which is the better
alternative, but I don't think it matters in this case and hence I
haven't provided a patch for that.

I confirm that I can reproduce the bug you've spotted.

Great finding you've done there... This is the kind of obvious thing very
difficult to spot...

And, in fact, the extract I sent early of August wasn't working for me. Well,
the same version from a multi-block agenda view. This completely corroborates
your sayings...

These are not mine: just the default ones when pressing `C-c M-m' when
composing a message in Emacs!

Indeed, while G is good, B is not firing up the "clock check" as expected.

[O] [BUG?] Duplicate agenda entries when enabling archives-mode

[Sebastien Vauban]

Hello,

If you use the following block of code, you'll see that all your entries are
duplicated.

For a clock review, this is much worse, as Org will warn about clocking
overlaps everywhere... (because multiple entries, then, happened at the same
time).

--8<---cut here---start->8---
(setq org-agenda-custom-commands nil)

(add-to-list 'org-agenda-custom-commands
 '("C" "Clock Review"
   ((agenda ""
(
 (org-agenda-archives-mode t) ;; <<<
 (org-agenda-clockreport-mode t)
 (org-agenda-overriding-header "Clocking Review")
 (org-agenda-show-log 'clockcheck)
 (org-agenda-span 'day))) t)))
--8<---cut here---end--->8---

Putting the `archives-mode' line in comments does solve the problem.

Best regards,
  Seb

[O] [export] Should sidewaystable option automatically add rotating package?

[Eric S Fraga]

Hi,

A minor feature request.  Feel free to ignore!

Using the sidewaystable :float option for table exports to LaTeX
requires one to manually add a 

  #+LaTeX_header: \usepackage{rotating}

line to the org file.  Could this package be added automatically by the
exporter if the sidewaystable option is present?

Thanks,
eric

I don't know what "pre-order" means. What about

I don't understand. Are you talking about the error message? There is no
"canonical" C-down position, so I'm a bit confused.

The above problem is back with the following configuration (tested with

   ((agenda ""

while there is only 1 command to be run (the agenda view)!?

Note, surprisingly, 2 extra spaces before the ":", while they're not in the
customized header string...

Please IGNORE IT!  This "bug" is due to a faulty placement of the parenthesis.

My 2¢:

I think the policy is that the ox-latex ain't going to track packages.
Aaron made some patches for this some time ago, but they weren't
included.

So the question is should it be a default package?

I think not.  E.g. tabu isn't loaded.  Amsmath isn't loaded if you
generate a matrix.  Also, a kitten dies every time the length of
org-latex-default-packages-alist increases!

Okay.  I can live with this!  

I guess it would help if the documentation indicated when additional
packages may be required.  I had to do an internet search to find out I
needed the rotating package for the sidewaystable option described in
the org info pages.

Well, this is documented on the LaTeX pages.  Why would you duplicate this
in Org's documentation?  And What part of the LaTeX documentation exactly?

It's fine with me if it's something like 

Float environment for the table. Possible values are sidewaystable
(requires

[[http://www.ctan.org/tex-archive/macros/latex/contrib/rotating][rotating]])...

Currently 12.7.4 LaTeX specific attributes under - placement :: ...,
it seems.

 Using the sidewaystable :float option for table exports to LaTeX
 requires one to manually add a 
 
  #+LaTeX_header: \usepackage{rotating}
 
 line to the org file.  Could this package be added automatically by the
 exporter if the sidewaystable option is present?

It certainly is, but the beauty of org is that it hides some of the
nitty-gritty to write LaTeX files (and odt - even more so).

One part would be 12.7.4 - LaTeX specific attributes.

It states:

,
| :placement 
| Float environment for the table. Possible values are
| sidewaystable, multicolumn, t and nil. When unspecified, a table with a
| caption will have a table environment. Moreover, :placement attribute
| can specify the positioning of the float.
`

An addition like:

,
| For some options, additional LaTeX packages need to be loaded. Please
| see LaTeX documentation for details.
`

Would suffice, and be general enough.

Cheers,

Rainer

Exporting to html, the .html it is displayed as:

I'm sorry my mistake. 
This has nothing to do with tree-slide. It happens with each org file
without header when you do not indent the first two lines at least
one space.

I think `org-format-latex-header' shouldn't load amsmath at all.

It's not about load time, but about compatibility with other packages.
I think some of them don't coexist well with amsmath. "amssymb" and
"amstext" are less demanding in that area.

[O] [wish, detail] Resume ordered lists

[Sebastien Vauban]

Hello,

Currently, ordered list items may be (re-)started with a different value
(e.g., 20), by writing the item with `[@20]'.

A nice-to-have feature would be the ability to resume a list at the previous
value + 1, such as:

  ╭
  │ 1. This
  │ 2. That
  │ 
  │ Some intermediate paragraph.
  │ 
  │ 3. [@resume] Those
  ╰

That would allow for more efficiency when adding or deleting items from the
previous list.

Best regards,

Okay, say I have an org file with two lines in it (fill-column is set to
70). Here you go:

--8<---cut here---start->8---
Jemand mußte Josef K. verleumdet haben, denn ohne daß er etwas Boeses
getan haette, wurde er eines Morgens verhaftet. Die Koechin der Frau
--8<---cut here---end--->8---

Then you go on with the text, which is:

Grubach, seiner Zimmervermieterin, die ihm jeden Tag gegen acht Uhr frueh
das Fruehstueck brachte,...

At each automatic line skip I get the mentioned error message. But if
you indent these two lines one space everything works fine.

OK. Suggestions welcome.

Except for the odd, typically, symbol package that should be loaded
after amsmath I'm not aware of any such cases.  I thought that nath
might have been an issue, but even that supports amsmath.

[O] setting options to python interpreter for a code block

[John Kitchin]

Hi,
I am looking at a new strategy to capture stderr and exceptions in python
code blocks. Right now exceptions are not captured in the output, and
neither is stderr.

I made a little sandbox module that captures stdout, stderr, and exceptions
and then prints them all to stdout with some minor formatting. Here is an
example.

Say test.py has this content

#+BEGIN_SRC python
print 'hello'

print 4 + 6

import sys

print >>sys.stderr, 'message to stderr'


raise Exception('baboom')
#+END_SRC

When I use the sandbox, I get all the output on stdout like this.

#+BEGIN_SRC sh
python -m sandbox < test.py
# or cat test.py | python -m sandbox
#+END_SRC

#+RESULTS:
#+begin_example

--
hello
10


--
stderr:
message to stderr


--
Traceback (most recent call last):
  File "/home/jkitchin/Dropbox/pycse/pycse/sandbox/sandbox.py", line 16, in

exec(content, ns_globals, ns_locals)
  File "", line 10, in 
Exception: baboom


#+end_example


So, I was wondering how to get this to happen in org-mode on a regular
python block. I think it could work if I could define a custom interpreter
for a particular block, e.g. python-sandbox that takes the codeblock on
stdin.

Is there some other way that I could do this? Thanks!

John

Strange, in deed. I can reproduce it even this way:

2. Add my org directory to the load path

This is interesting but not really possible at the moment. Currently
Elements implement "successors" functions, which are basically
a `re-search-forward' on some hard coded regexp and a predicate to check
if we're really where we think we are. So moving to the next object is
easy, but moving to the previous one would be awkward.

In order to allow this, we should first change the innards of Elements
and split "successors" in two parts:

  1. an association list between object types and regexp
  2. a predicate

Then we would be able to move either way.

If there's some real interest in it, I can have a look, but not right
now.

No, and I have figured out why. 



The table was ill-formed.  It was originally part of an email I had cut
and pasted into a diary item and I had never asked org to "format" it
which, if I had, would have added an extra column throughout.  It's
interesting that the exporter used to work.  It *is*, however, a long
time since I updated my org as I was away all of August (without a
computer!) and have been doing the headless chicken impression ever
since trying to catch up ...



If it helps, here is a minimal example:

--8<---cut here---start->8---
* table test for export
|Milestone / Deliverable  |WP  
|Responsibl|Due:|
| ||e | 
   |
|M7.1  |UCL to have developed and exercised test bed  |7   |UCL   
|30th|
--8<---cut here---end--->8---

Note the extra | before the first UCL in the last line of the table,
something which I hadn't spotted.

Thanks for making me look at this closer and sorry for the noise.

Re: [O] setting options to python interpreter for a code block

[Eric Schulte]

You could try setting org-babel-python-command to "python -m sandbox".

If that doesn't work we could add a cmdline header argument to python
code blocks pretty easily.

[O] BUG: clicking on timestamp destroys buffer ordering and point

[Samuel Wales]

I like the feature where you can RET or click on a timestamp.
Recently in git master, it changes the buffer list so that the buffer
you are in is off in some random location.  You cannot get back to it
with next-buffer.

I bind this to a function key and operate in full screen (I never
split windows).  It is my primary means of buffer navigation.  Almost
all of Emacs will get you to the buffer you were just in if you do
next-buffer, and back again with previous-buffer.  Thus, it is sort of
like a back command in a browser.  This is true for almost any
buffer-creating command like org-agenda.  (I don't use the click on
timestamp feature that much, but it would be nice if it worked this
way also, and the fact that it does not might indicate that other
areas of Org might not, now or in the future, so this is a bug report
intended to prevent future bugs more than a critical current need.)

Also, I noticed that point in the original buffer gets placed at bob.
IMO it should stay where it was.

Thanks.

Samuel

You mean property drawers after headlines?  I would think skipping them

One thing I feel the need for is to be able to navigate longer source

[O] LaTeX export: images subplots

[Martin Leduc]

Hi all,
  I am using org-mode to write a report with several figures. I would like to 
group some images into a same figure, let say a 2x2 panel. I know that I can 
directly embed latex code in my org file, for example by using the subfloats 
(from the latex subfig package). 

However, I would prefer to use an org-based solution of inserting the image 
links in order to keep the convenient way of previewing images right into the 
buffer with C-c C-x C-v.

The only solution I found is by using tables such as:

#+CAPTION: Insert caption here.
#+ATTR_LATEX: :align p{0.5\textwidth}p{0.5\textwidth}
| [[pathtoimage]] | [[pathtoimage]] |
| [[pathtoimage]] | [[pathtoimage]] |

where the size of the images is controled by p{} and C-cxv is working. However, 
in the exported TeX file, it is a table, not a figure. Is there a cleaner way 
to make image panels that would preserve the figure environment in the exported 
TeX file ?

Thanks a lot,
Martin

Just wanted to cite my similar (same?) question from a bit back:
- http://lists.gnu.org/archive/html/emacs-orgmode/2013-03/msg01800.html

The only suggest I got was to use the subfig package, which may
actually be something like what you're looking for.

I guess p{width} /could/ work for what I was going for, but I will
often stagger images and my own "captions" via the org table:

#+ATTR_LATEX: :align p{0.5\textwidth}p{0.5\textwidth}
| [[pathtoimage]] | [[pathtoimage]] |
| /blah blah/  |  /blah blah/  |
|   |   |
| [[pathtoimage]] | [[pathtoimage]] |
| /blah blah/  |  /blah blah/  |
|   |   |

I don't like using p{} because everything is left aligned and I like
to center the images and the "caption" text below each one.
Unfortunately, there's no centered equivalent to p{}. Thus, I end up
using \includegraphics[widt]{} manually.

Anyway, sorry if that's off-topic. Just wanted to voice that I have a
use for this general sort of thing as well. Heck, I think even
applying the beamer columns principle to LaTeX article classes would
work and be quite neat.

John

Re: [O] LaTeX export: images subplots

[Martin Leduc]

Hi John, 
   this solution using tables was indeed inspired from your post, I am so 
sorry, I should have refered to it...

I suppose that the feature has not been implemented yet. I am now thinking of 
generating a panel with imagemagick before including it in the org buffer, for 
example with

#+begin_src sh
convert +append image1.png image2.png panel.png
#+end_src

and hence 

#+CAPTION:
[[panel.png]]

to have the two images side by side both in the buffer (with C-cxv) and the 
latex pdf (within a figure environment).

Is there a cleaner org solution that I would have missed ?
Thanks again,
Martin

What in the wide world of sports!? That's amazing and I can't believe
I've never run into that. Sooo flipping handy. I've been looking for
an easy way to do this with dissimilar ggplot2 plots where facetting
is hard or doesn't make sense as well:
- Like this: 
http://stackoverflow.com/questions/18046051/setting-individual-axis-limits-with-facet-wrap-and-scales-free-in-ggplot2

That's pretty awesome and I just tried it; works beautifully.

Then again, I think handling images in Org tables would be just
fantastic. Not need for an external program or the compile time.
Perhaps a bit tricky as one would have to infer from some #+attr_latex
property that one wanted to apply some size parameter to every
[option] box of the converted \includegraphics line...

In any case, thanks for this and I'll keep that in mind. Hopefully
others chime in.

I think you are close.

Use 

#+BEGIN_SRC org :exports none
#+name: imtable

#+END_SRC


This gives you the images in a form you can view and a way to access the
links so you can export them in a different form.

For example,

#+BEGIN_SRC emacs-lisp :var a=imtable :exports results :results raw
  (mapconcat (lambda(y) 
   (mapconcat 
(lambda(x) (org-export-string-as x 'latex t)) y "")) a "")
#+END_SRC

exports as 

\includegraphics[width=.9\linewidth]{img3070YH.png}
\includegraphics[width=.9\linewidth]img307BjN.png}
\includegraphics[width=.9\linewidth]img307OtT.png}
\includegraphics[width=.9\linewidth]img307b3Z.png}

when the elements in the table are the image paths img*.png as shown.
