Re: [O] Problem exporting to PDF (and viewing)

[Richard Stanton]

Checking further, this works fine using the default Windows shell in Emacs, but 
fails if I use bash as my shell. Unfortunately, I like to use bash, which I 
achieve with the following lines in my init.el: 

  (setq shell-file-name "bash")
  (setenv "SHELL" shell-file-name) 
  (setq explicit-shell-file-name shell-file-name)

Re: [O] ATTR_HTML for a clickable image, howto?

[Samuel Wales]

Hi Christian,

Thanks for your thoughtful comments.  I have a better understanding of
it now.  Here is more as a sort of summary for searchers.

On 2012-04-11, Christian Moe  wrote:

I mean this: "If prefix arg body-only is set, omit file header,
footer, and table of contents, and only produce the region of
converted text, useful for cut-and-paste operations." (from the
docstring).

Blogger (and many other places online) already has a HEAD section, and
my understanding is that you can't have 2 HEAD sections.  (I presume
there does not exist a "HEAD-APPEND" section in the HTML standard.)

So letting Org produce the HEAD section seems to be not possible here.

To summarize, it appears as if you can't use full CSS (like "whatever
{ whatever: whatever; }") as a wrapper at all in the body section, so
you need a HEAD section or a separate CSS file to be able to style
specific types of elements the way it is normally done.  The rough
Lisp analogy seems to be that you cannot use let to bind a variable
that is used in various places, but you can use setq (in a section
that can only be used once) or load.

That's the answer I was looking for.  I looked it up more and it seems
to be the case.

Thanks.

I don't understand this enough yet to know how much effort would be
required.  Good to know you think it might work.

[O] Problem exporting to PDF (and viewing)

[Richard Stanton]

Using Org-mode version 7.8.09 (release_7.8.09-553-g5750f0) (and earlier 
versions) I've encountered a problem on my Windows machine when I try to export 
an Org file to LaTeX, then to Pdf, then viewing (using C-c C-e d).

In my init.el I have the lines

  (eval-after-load "org"
'(progn
   (if (assoc "\\.pdf\\'" org-file-apps)
   (setcdr (assoc "\\.pdf\\'" org-file-apps) 
"c:/progra~1/sumatrapdf/sumatrapdf.exe  %s") 
 (add-to-list 'org-file-apps '("\\.pdf\\'" . 
"c:/progra~1/sumatrapdf/sumatrapdf.exe %s") t
)

This results in:
 
org-file-apps is a variable defined in `org.el'.
Its value is ((auto-mode . emacs)
 ("\\.mm\\'" . default)
 ("\\.x?html?\\'" . default)
 ("\\.pdf\\'" . "c:/progra~1/sumatrapdf/sumatrapdf.exe %s"))

When I try to export an org file by typing C-c C-e d, sumatrapdf opens up OK, 
but complains with an error like this:

Error loading c:\dropbox\org\c\:\dropbox\org\personal.pdf

Any idea why I get the repeated path? A similar constructions works fine on my 
Mac, so I'm not quite sure what's going wrong here.

Hi Andreas,

Thanks for reporting and for bisecting (which made fixing much easier).

I believe that if given a :file header argument the gnuplot block will
return the path to the altered file as it's return result.  You could
use a :var header argument to feed this path into a shell script code
block which could call eps2eps on the resulting file.

With this setup, every time the sh code block is evaluated it will call
the gnuplot code block before it is run.  See the relevant manual
chapter for more information.

Hi John,

I wrote the org-collector some years ago, but haven't used it in a long
time.  After a quick scan your comments look great, and I'm sure they
would improve the worg page, so please go ahead and make any changes you
see fit.  My one caveat is that you may want to (if you haven't already)
look through the org-collector.el file for comments, which may explain
some of the surprising behaviors.

Thanks,

[O] Feedback on org-collector Worg page

[John Hendy]

I'm happy to do the updating that might come out of these comments.
Org-collector was recently mentioned on the mailing list and I took a
second to play with it a bit by following the page on Worg.
-- http://orgmode.org/worg/org-contrib/org-collector.html

The location of the src table was not specified in the article. I
found out after a bit of trial and error that the org-collector block
will search only the previous headline and any children. Thus, one
needs to be careful where the org-collector block is. To use the
example on Worg, someone might create their financial tracker document
like so:

--
* Statistics
[bunch of org-collector blocks]

* Raw Data
** Jan Purchases
** Feb Purchases
** Etc.
--

This would not work, as the org-collector blocks are only looking in
the "* Statistics" headline. This is probably worth mentioning on Worg
if I'm correct (again, I'm happy to do this). Either that, or perhaps
the scope of the headlines searched could be changed if others find
this undesirable. Or I've totally botched and don't have the right
understanding and this is all a false alarm! :)

Secondly, I was attempting to use this on my contacts.org file and
kept getting errors. Probably a bad first start for a guinea pig file.
I finally narrowed down that my :Phone: property in the form "(xxx)
xxx." was causing the error. It seems that properties with
parentheses cause org-collector to try and run it as a function. If I
add a property to the example file (call it "foo") and give it the
value "(test)", I get the error on C-c C-c "(void-function test)".

Comments?

Aloha Rainer,

* section

\pagebreak
** subsection 1
** subsection 2

Would this work?  Note that \pagebreak doesn't have a required
argument--the optional argument \pagebreak[] lets LaTeX decide whether
or not to break the page.

Hi all,

[O] "Wrapping" section into LaTeX statements?

[Rainer M Krug]

Hi

I want to wrap a section of a document into LaTeX statements, as I would like 
to redefine
\subsectionbreak so that it does a \pagebreak before - but *only in one 
section*:

* A normal section
* Here I want the redefinition
#+BEGIN_LaTeX
  \let\oldsubsection = \subsection
  \renewcommand{\subsection}[1]{
\pagebreak{}
\oldsubsection{#1}
  }
#+END_LaTeX
** subsection 1
** subsection 2
* And here I want to use the old sectionbreak
#+BEGIN_LaTeX
  \renewcommand{\subsection}[1]{
\oldsubsection{#1}
  }
#+END_LaTeX
** subsection 1
** subsection 2

Now I can do this as above, but I don't like it, as the second LaTeX code 
actually should be at
the end of the previous section and if I insert a section, I have to move the 
LaTeX code.

I could put it into the previous section, but then it would be in the 
subsection 2, and if I add a
subsection 3, I would have to move the LaTeX code into this subsection.

So nothing is optimal - is there an alternative which makes more sense and is 
easier to maintain?

Thanks,

Rainer
