Hi, and thanks for the feedback.

I was initially tempted to suggest that nil would indeed be a better
default for this variable, but in this related post
https://lists.gnu.org/archive/html/emacs-orgmode/2013-05/msg00287.html
Samuel Wales says that

  "It defaults to `t' which I think is a good default."

Considering the time that you experts spend on endless discussions
about what the default value of some variable should be, I'd rather
remain agnostic on this one.  But unless the use of this variable is
obsolete, I feel it has to be documented -- could be as discreet as
one sentence in a footnote.  Otherwise, with a nil default, even
people using the export features would have difficulties to know about
it.

(More generally, what would be the harm of having some appendix with a
list of all customizable variables?  Seems to me it could help
beginners to learn Org; sure, there is 'C-h v org-', but it's not
exactly the same for me.)

[O] Latex export error: There's no line here to end, with an image with a caption

[Takeshi Teshima]

Hi all,

A happy new year!

I have a problem with org-export-to-latex.

# What happens

## [1]

When I try to export an org-mode file **that contains a figure with a  
caption** with `#+OPTIONS: \n:t`, (See minimal example files)


to a pdf via latex-export, the exported latex file doesn't compile and I  
get the following error:


```

LaTeX Error: There's no line here to end.

```

in the `*Org PDF LaTeX Output*` buffer. Thus this is an error from the  
command line.


## [2]

So I go to the line of the .tex file that's specified in the error, and  
the line always says:


``` latex

\end{figure}\\

```


## [3]

If I remove the double backslashes by hand, and compile the generated  
.tex file from the command line, it produces a pdf correctly.



# My environment

I've checked this with:

[1] Org-mode version 8.3.6 (8.3.6-7-g4d7d52-elpa @ ~~~)

[2] Org-mode version 8.2.10 (release_8.2.10 @ ~~~)

[3] Org-mode version 9.0.3 (9.0.3-elpa @ ~~~)

, but the same errors occur.

(I normally use version 8. I know this is an old version. However, v9  
has another problem with #+TITLE: lines. See  
https://github.com/syl20bnr/spacemacs/issues/3246 for more details)



# Reproducing the error

## Files

Attached, please find the files for a minimum example.

- test.org

- test-2017-01-06-17-05-09.jpeg


## Procedure to reproduce:

1. Place the files in the same directory

2. $ emacs -q test.org

3. M-x org-latex-export-to-pdf

(Or instead of 2., your own emacs config will do)


# What I already found

- The caption is necessary to reproduce the error.

- The problem occurs with a single image.

- If I remove the double backslashes by hand, and compile the generated  
.tex file, it compiles correctly.


- The problem doesn't occur with `#+OPTIONS: \n:nil` (which is kind of  
trivial)



# Reference

A relevant thread can be found here:

https://lists.gnu.org/archive/html/emacs-orgmode/2016-09/msg2.html

but I couldn't find a solution there.


Anyone has any ideas? Any idea to bypass this problem may be a lifesaver  
for me.

[O] org-collector not working

[Malte Deiseroth]

Hello

The org-collector seems to be broken. I followed the instructions on:
http://orgmode.org/worg/org-contrib/org-collector.html

Instead of:
#+BEGIN: propview :id "december" :conds ((string= spendtype "food"))
:cols (ITEM amount)
| "ITEM"   | "amount" |
|--+--|
| "Grocery Store [2008-12-01 Mon]" |56.77 |
| "Restaurant [2008-12-08 Mon]"|30.67 |
|--+--|
|  |  |
#+END:

I get:

#+BEGIN: propview :id "december" :conds ((string= spendtype "food"))
:cols (ITEM amount)
| ITEM | amount |
|--+|
|--+|
|  ||
#+END:

and instead of:

#+BEGIN: propview :cols (ITEM (+ 400 amount)) :scope tree :match "example"
|
"ITEM" 
| "(+ 400 amount)" |
|-+--|
| "December Spending  
:example:" |0 |
| "Week

|0 |
| "Restaurant [2008-12-08
Mon]"   |   430.67 |
|-+--|
|   
 
|  |
#+END:


I get:

#+BEGIN: propview :cols (ITEM (+ 400 amount)) :scope tree :match "example"
| ITEM | (+ 400 amount) |
|--+|
| "** December Spending"   |  0 |
| "*** Week One"   |  0 |
| " Grocery Store [2008-12-01 Mo]" |  0 |
| " Athletic club [2008-12-02 Di]" |  0 |
| "*** Week Two"   |  0 |
| " Restaurant [2008-12-08 Mo]"|  0 |
|--+|
|  ||
#+END:

Basically all the columns/properties are always 0. I tried also with
other properties, but nothing worked.
I have nothing in the *Messages* or *Warnigns* buffer to post here.
I might be doing something wrong. Its the first time using org-collector
for me.
I'm using emacs 25.1.1. I believe org-mode and org-collector are shipped
by default with this.
Any help would be appreciated.

Cheers Malte

[O] Error when =(stata . t)= added to =org-babel-do-load-languages= in an attempt to evaluate Stata code in org-mode

[Daniel Guinea]

Hello,

I have built the latest Emacs 26.0.50.1 on a Debian OS 8 (Jessie) that
uses Linux version 3.14.5. Then I installed org-mode version 9.0.3. I
want to use the proprietary data analysis and statistical software
Stata version 14. I have checked that it runs alright within Emacs
thanks to ESS by typing  =M-x stata=.

However, I also want to evaluate Stata code in org-mode documents. For that
I have
downloaded the script =ob-stata.el= by Ista Zahn and I have saved it
together with the other =ob-sth.el= files in
=~/.emacs.d/elpa/org-20161224=. Moreover, I have edited the entry:

(defcustom org-babel-stata-command inferior-STA-program-name
  "Name of command to use for executing stata code."
  :group 'org-babel
  :version "24.1"
  :package-version '(Org . "8.3")
  :type 'string)

to reflect my current version of Org, so this piece of code currently
stands as follows in my version of  =ob-stata.el=:

(defcustom org-babel-stata-command inferior-STA-program-name
  "Name of command to use for executing stata code."
  :group 'org-babel
  :version "24.1"
  :package-version '(Org . "9.0.3")
  :type 'string)


However, if I add =(stata . t)= to =org-babel-do-load-languages= as follows:

(org-babel-do-load-languages
   'org-babel-load-languages
  '((emacs-lisp . t)
(sh . t)

[O] Can a code block be evaluated in multiple sessions

[Jack Li]

Hi,

Can anyone tell me if a code block can be evaluated in multiple sessions?
In this toy example I provide, function "f1" is defined in the first block,
 and I want to use "f1" in both the second block (session a)  and the third
block (session b).

#+BEGIN_SRC R
  f1 <- function(x,y,z) x+y+z
#+END_SRC

#+BEGIN_SRC R :session a
f1(1,2,3)
#+END_SRC

#+BEGIN_SRC R  :session b
f1(2,4,6)
#+END_SRC

PS: the three blocks should be in one .org file, and, when exporting,
"session a" and "session b" will be run simultaneously and independently.

Thanks,
Jack

Unfortunately I don't have publishing setup. I usually export one subtree at a 
time manually and create a separate file, as I tend to tweak each class' 
contents before actual lecture day.

org-html-with-latex is t and org-export-with-latex is also t. I don't have

[O] [feature request] more informative error message when calling an undefined src block

[Eric S Fraga]

Hello all,

I have been trying to track down a nil link on export [1].  I have been
bisecting a long document.  As part of this, I commented out a src block
used elsewhere in the document.  The error trace [abridged] I get upon
export is:

Debugger entered--Lisp error: (wrong-type-argument consp nil)
  org-babel-exp-code(nil lob)
  org-babel-exp-do-export(nil lob)
  org-babel-exp-process-buffer()
  org-export-as(latex nil nil nil (:output-file "t.tex"))
  
which was luckily just enough for me to figure out what I had done but I
think it could be more informative?  E.g. it would be nice if it said
which code it tried to invoke?

Thanks,
eric

Footnotes: 
[1]  related problem: "Unable to resolve link: nil" is not very
informative either and it's driving me crazy!  I've not yet tracked down
what the problem is but it has something to do with using my own labels
for tables.  More later when I figure it out.

No, the default with a plain vanilla install is MathJax. In your minimal init 
environment,
what is the value of org-html-with-latex? What about org-export-with-latex? 
Both of these
should be t by default.

If they are, I would edebug org-html-format-latex, run the export and,
when it stops at org-html-format-latex, look at its arguments: the
second argument is the processing-type and it *should* be mathjax.

Maybe you have a mixed installation. I cannot reproduce your problem

[O] callback function on async export?

Is there some way to get a call back function, or trigger a function
when the async export completes?

I use

Works well.

Then you can control appearance through CSS. For instance:
.MathJax_Display {
    color: #080;
    margin: 0;
}

Have fun

Well, on the test-case your change made recalculation linear (which is
good):

I think I was unclear.  My confusion is that a tree (rooted at a top
level headline) that I do not want exported is nevertheless exported if
a subtree within that tree has a "selected" tag.  I would have thought
the higher level heading would take precedence.

> I am surprised you can use comment like this. It looks to me like

Yes, it is.  Again, I obviously didn't explain myself well.  I have
resorted to commenting out whole trees (rooted at headlines) to avoid
them being exported because a sub-tree has the selected tag.

In any case, I have found a workaround by inverting my tag usage.

thanks,
eric

Re: [O] HTML export for math markup

[Lawrence Bottorff]

The default behavior with a plain vanilla installation is, indeed, to use
png files and create the ltximg subdirectory. It's not a huge problem, but
I'd prefer it not doing that; instead, using MathJax. Anyone know how to
switch this behavior?

MathJax should be the default behaviour. See `org-html-with-latex'.

Have you tried exporting with a minimal init file and none of your 
customizations?

Re: [O] excluding whole trees on export when subtrees have "select" tags present

[John Kitchin]

Based on the docstrings for org-export-select-tags and
org-export-exclude-tags, this looks expected.

It does not look possible to exclude a heading and include a subheading
under it. It is possible to include a heading and exclude some
subheadings though you need a wanted tag in the parent, and notwanted
tags in the subtrees, and to declare the exclude tags.

#+EXCLUDE_TAGS: notwanted

I am surprised you can use comment like this. It looks to me like
commenting a tree makes all the subtrees in it not export too.

I could see somehow an org-export-before-processing-hook function that
deletes headlines and content you do not want, but it will mess with the
outline, e.g. if you delete "* headline" but leave "** subhead".
I thought I would be able to comment headlines with a hook function like
this, but I could not get it to work. Maybe it is a local problem though.

Why do you mean by "do not work". I reproduced your example and can follow the

[O] excluding whole trees on export when subtrees have "select" tags present

[Eric S Fraga]

Hello all,

In this very minimal example,

#+begin_src org
  ,#+select_tags: wanted
  ,* headline   :notwanted:
  some text
  ,** subhead :wanted:
  more text
#+end_src

exporting exports the whole tree under /headline/.  I can see why but it
is arguably the wrong thing to do.  If /notwanted/ hasn't been selected,
I would have assumed that all the contents under that headline would be
ignored during export.

My problem is that I want to export a document where certain headlines
(but not all) are included *and* within these, some subheadlines are
also included but not all.  I would be specifying one or two tags for
selection depending on the specific export case.

I can achieve what I want by commenting and uncommenting headlines but
this is very clumsy and error-prone for my use case.

I guess I simply want to confirm that the above noted behaviour is
indeed what is expected from org.  If so, I will find a work-around.

Thanks,
eric

At the moment there's no direct support for [description] for any
variables in KOMA letters generated through Org.  What is the use-case
here?

The default description is "Url" and it does not have a corresponding
"symbolicname".

In general, descriptors are used in headers or footers which would
typically be set up in a separate LCO file, I’d guess.  E.g.

  \ifkomavarempty{fromurl}{}{\usekomavar*{fromurl}\usekomavar{fromurl}}

This should be done for all komavars if it was to be added IMO.
