This seems to a problem with your setup of preview latex.  It
should work just fine.

For me the following org file works as expected -- also with
previewing the equation.

--8<---cut here---start->8---
#+LaTeX_header: \usepackage{amsmath} %% needed explicitely for org-preview-latex


* Test align

\begin{align}
(x+y)^3&=(x+y)(x+y)^2\\
   &=(x+y)(x^2+2xy+y^2)\\
   &=x^3+3x^2y+3xy^3+x^3.\qedhere
\end{align}
--8<---cut here---end--->8---

I do not seem to have any special setup for previewing latex,
though...

Sorry to be of no further help.

Andreas

This sounds like a mixed installation: different versions of org
installed and you are picking up bits from both of them.
Search the list for "mixed installation", e.g. check out

http://thread.gmane.org/gmane.emacs.orgmode/68240/focus=68265

and the link therein:

(Untested!)

I suspect that this is due to org-latex-prefer-user-labels being
nil.  This will make Org mode inserting auto-generated labels.
Setting this to sth non-nil might work here.

Maybe I'm missing something, but can't you just add asterisks in front
of each line? Maybe with a keyboard macro? Or even a sed script?

There's a reason that org files are plain text.

Re: [O] Modification dates in Worg (was: babel header arguments tutorial?)

I've created a worg mirror on github at

dates via git-blame. For example,
https://github.com/izahn/worg-mirror/blame/master/org-contrib/babel/languages.org

Re: [O] Exporter aborts upon encountering even one unresolvable link

[thomas]

just my 2 cents: I think the new error message is very nice and helpful, 
UNLESS you work on a bigger document, narrow your buffer and try to 
export the narrowed portion of the document.

This does not work anymore.

I can agree with D. C. Toedt that it would be nice to have an easy way 
to customize this behaviour of the exporter.

From this thread 
 
I see that the exporter now throws an error and aborts when it 
encounters an unresolvable link. That makes things really, REALLY 
difficult.  It means I can't get a complete, working export to HTML 
(in my case) until all link problems are fixed in my 22KLOC .org file 
(which I use to generate http://www.CommonDraft.org/index.html 
). That seems EXTREMELY 
suboptimal. (I'm trying to be tactful here.)


Worse, the exporter doesn't even generate a list of unresolvable links 
before aborting. That means the only way that I can find and fix 
busted links (so far as I know) is to do an export --- which takes 
several minutes given the large file  --- and have the export abort on 
a single link. Then I fix that one link, export again, and have it 
abort again. Repeat.  Aaaargg.


I started looking at the hooks, as suggested in a message in the 
previous thread, but I'm not nearly skilled enough in elisp to be able 
to do anything useful.


Any suggestions?

[O] [PATCH] Reverse capture finalize and refile, hack buffer killing.

[Jan Seeger]

* org-capture.el (org-capture-refile): Call finalize first, then
  refile. If the capture buffer needs to be killed afterwards, kill
  after refiling.

Refiling before finalizing led to an incorrect cursor position during
refile. Since adjusting the buffer position and bounds for the refiled
entry is difficult, I reverted the org-capture-refile function to its
original order of finalizing and then refiling. However, this leads to a
bug with killing the buffer on capture, described in
http://permalink.gmane.org/gmane.emacs.orgmode/78027/. To work around
this, now the :kill-buffer flag is cleared before calling finalize, and
the capture buffer is killed after org-refile is called.

[O] Beamer :BEAMER_envargs: [allowframebreaks] not working

[Jeremie Juste]

Hello,

It's my first post here finally. Most of my questions were answered
before by you.:). I have the lastest version of org mode and search
with the best of my abilities if any had the same issue but couldn't
find anything.

I have some difficulty with the org-mode variable :BEAMER_envargs.

It does not allow frame break. There was a post on SO about the issue

http://stackoverflow.com/questions/29384107/org-mode-framebreak-does-not-work-with-label-option-in-exported-beamer

As a fix they recommend the following fix
(setq org-beamer-frame-default-options "allowframebreaks,label=")

This doesn't do the job and on the tex file it produces something like
\begin{frame}[allowframebreaks,label=,label={sec:orgheadline1}]{part 1}

I tried with
(setq org-beamer-frame-default-options "allowframebreaks")
but the results were not better,


Finally removing label={sec:orgheadline1} did the job.
\begin{frame}[allowframebreaks]{part 1}

So I suspect there is a problem with label={sec:orgheadline1}.


Can someone help please?

Best
JJ

This is a very good point.  OTOH, if backwards compatibility is going to
be broken, wouldn’t it be better to move to a keyword argument system?
IOW, the signature of ‘org-export-as’ and friends would change from:

(backend  subtreep visible-only body-only ext-plist)

to (using cl-defun):

(backend  subtreep visible-only body-only ext-plist draft)

This would allow future changes to the API of this function without
breaking backwards compatibility.  It would also clean up messy
constructs like:

(lambda (a s v b d)
  (if a (org-org-export-to-org t s v b d)
(org-open-file (org-org-export-to-org nil s v b d

which could become:

(lambda ( kwargs)
  (if (plist-get kwargs :async)
  (apply #'org-org-export-to-org kwargs)
(org-open-file (apply #'org-org-export-to-org kwargs

and with further simplification the following, which is vastly clearer
than the original:

(lambda ( kwargs)
  (let ((result (apply #'org-org-export-to-org kwargs)))
(unless (plist-get kwargs :async) (org-open-file result

Since this stanza recurs in the code for most (all?) backends, there’s
some value that org core can provide to backend authors by making it as
simple as possible.

With a non-trivial effort, the old calling convention could still be
supported (if the argument after ‘backend’ is not a :keyword, then
org-export-as knows that the old convention is in use, and it should
map the arguments 2 through 5 to the relevant keywords).  It could
trigger a deprecation warning and be phased out with the next major
version (or whenever).

On a different note, does this scheme make it possible for a backend
to see whether draft mode is enabled?  Latex provides a document-level
draft option, which enables certain optimizations that speed up compile
times (for example, graphics are not read in, but are replaced with a
placeholder).  It would be nice if ox-latex could emit this in the latex
code when draft mode is enabled from the org side.

Thanks,

(x+y)^3&=(x+y)(x+y)^2\\
   &=(x+y)(x^2+2xy+y^2)\\

--8<---cut here---end--->8---

but with latex fragment preview (C-c C-x C-l) I only get an empty frame.

How can use this align environment in org?

I could use


--8<---cut here---start->8---
\begin{eqnarray*}
\hat{f}(x) & \propto & \sum_{\nu} \frac{|F(\nu)H(\nu)|^2}{|N(\nu)|^2}  
   \frac{G(\nu)}{H(\nu)} e^{\frac{2 \pi i \nu x}{N}}\\
   & \propto & \sum_{\nu} \frac{|F(\nu)|^2}{|N(\nu)|^2} H(\nu) H^*(\nu) 
   \frac{G(\nu)}{H(\nu)} e^{\frac{2 \pi i \nu x}{N}}\\
   & \propto & \sum_{\nu} H^*(\nu) G(\nu) e^{\frac{2 \pi i \nu x}{N}}
\end{eqnarray*}
--8<---cut here---end--->8---

but eqnarray is apparently bad (see link above).

Thanks,

Rainer
