Re: [O] [PATCH] call_*() is not working inside #+DATE

[Rafael Laboissiere]

* Rafael Laboissiere  [2016-03-07 02:58]:


The following used to work for me in the past:

  #+NAME: date
  #+BEGIN_SRC sh :results silent :exports results :tangle no
  date
  #+END_SRC
  #+TITLE: Sample
  #+AUTHOR: Me
  #+DATE: call_date()

and I saw the output of the shell command "date" when exporting the 
file to LaTeX.  However does not work for the current HEAD of the Git 
repository.


Using git-bisect, I discovered that the culprit is commit 85ff663, 
i.e. my code above works for commit 85ff663^ but fails for commit 
85ff663.


Commit 85ff663 was a pretty large commit and, besides that, the new 
code introduced by it was posteriorly changed, so it is hard to find 
where the bug comes from.  Could someone more acquainted with the code 
try to look at this bug, please?


I investigated this issue further and discovered that the constructs 
call_(args) and src_{code} are not evaluated at all when they 
appear in a keyword line (starting with "#+:").  Org-babel 
behaves in this way probably on purpose.  At any rate, it would be better 
if the current behavior is documented somewhere.  This may be 
accomplished with the patch attached below.


Best,

Rafael Laboissière

P.S.: For those who are reading this message and are interested in a 
solution for my original problem, here is the way I am getting around it 
right now.  When exporting to LaTeX, I wanted to have, as the contents of 
the \date{} macro, the date and the hash of the last Git commit of the 
current checkout HEAD, to which my Org document belongs.  Here is how I 
am doing it now:


   #+TITLE: Sample
   #+AUTHOR: Me
   #+BEGIN_SRC sh :results silent :exports results :tangle no
   git show -s --date=short --format="%cd [%h]" HEAD > GitDateCommit.tex
   #+END_SRC
   #+DATE: \input{GitDateCommit}

Seems good.

You are right, Oz, this can be fixed in line 147.
But :flags is intended for flags like -g or -O, which need
to appear
before the source file.

Probably we are missing an additional flag, which could be
named :libs
Then your example would be:

  #+BEGIN_SRC C :includes '( )
:libs -lm
  int i=9;
    printf("%d\n",(int)sqrt(i));

[O] Bug: ox-html.el does not indicate enough languages [8.2.10 (release_8.2.10 @ c:/Users/txiong/emacs-24.5/share/emacs/24.5/lisp/org/)]

[Tianxiang Xiong]

Remember to cover the basics, that is, what you expected to happen and

what in fact did happen.  You don't know how to make a good report?  See



 http://orgmode.org/manual/Feedback.html#Feedback



Your bug report will be posted to the Org-mode mailing list.





In the file "ox-html.el", the following bit of CSS displays the source

code block language's name on hover:



  pre.src:hover:before { display: inline;}

  pre.src-sh:before{ content: 'sh'; }

  pre.src-bash:before  { content: 'sh'; }

  pre.src-emacs-lisp:before { content: 'Emacs Lisp'; }

  pre.src-R:before { content: 'R'; }

  pre.src-perl:before  { content: 'Perl'; }

  pre.src-java:before  { content: 'Java'; }

  pre.src-sql:before   { content: 'SQL'; }



Org supports far more languages than this. In Section 14.7 of the Org

manual, the following languages are listed (formatting is screwed up):



  Language Identifier Language Identifier

  Asymptote  asymptote  Awk  awk

  Emacs Calc   calc   CC

  C++  C++Clojure  clojure

  CSS  cssditaaditaa

  Graphviz dotEmacs Lisp   emacs-lisp

  gnuplot  gnuplotHaskell  haskell

  Oz   oz Perl perl

  Plantuml plantuml   Python   python

  RR  Ruby ruby

  Sass sass   Scheme   scheme

  GNU Screen   screen shellsh

  SQL  sqlSQLite   sqlite



"ox-html.el" should support at least all the languages that Org mode
supports by default.

Use the ignoreheading environment in beamer to create an empty slide
before the one you want with a background and then one after to reset
the background, as in:

#+begin_src org
  ,* define background:B_ignoreheading:
  :PROPERTIES:
  :BEAMER_env: ignoreheading
  :END:
  ,#+latex: \usebackgroundtemplate{\tikz\node 
{\includegraphics[width=\textwidth]{mybackpic}};}
  ,* My slide with background
  is here
#+end_src

The above assumes that top level headlines are frames, i.e. H:1 default.

This was a misleading way for me to describe this.  git cherry-pick has

Re: [O] org-babel C math.h issue

[Oz Ben-Ami]

Thanks for the response.

On my machine, I get the undefined references even with GCC 5 (gcc version
5.2.1 20151010 (Ubuntu 5.2.1-22ubuntu2)), if I put -lm before the source
file name.

As far as a patch, I can try but this would be my first time really playing
with org-mode code. As far as I can see, I would need to add the following
lines in ob-C.el:
L133: (libs (cdr (assoc :libs params)))
 (libs (mapconcat 'identity
   (if (listp libs) libs (list libs)) " "))
L142: (format "%s -o %s %s %s %s" ;; (added %s)

Re: [O] org-babel C math.h issue

[Thierry Banel]

To summarize this thread:
It seems there was an issue long ago.
Version 5 of GCC magically fixed it.
But it is still here for older compilers.

-

To debug, execute the following piece of lisp code:

(defadvice org-babel-eval (before xxx (cmd body))
  ""
  (message "org-babel-eval : %s" cmd))
(ad-activate 'org-babel-eval)

The actual compilation command will be displayed in the *Messages* buffer.

With your example, we get

   gcc -o /tmp/babel-8412zIw/C-bin-8412IZR -lm
/tmp/babel-8412zIw/C-src-84127OL.c

--

You are right, Oz, this can be fixed in line 147.
But :flags is intended for flags like -g or -O, which need to appear
before the source file.

Probably we are missing an additional flag, which could be named :libs
Then your example would be:

  #+BEGIN_SRC C :includes '( ) :libs -lm
  int i=9;
  printf("%d\n",(int)sqrt(i));
  #+END_SRC

--

Oz, do you think you would be able to provide a patch?

Thanks.  It almost works :)

Applying the patch fails because there's a whitespace change in one of
the context lines (the first one above the org-table-align change).  You
should be able to see the same failure on your end if you make a test
branch off of maint and then try to apply your patch.  But the patch
applies fine with the --ignore-whitespace flag to git am, so there is no
need to resend it.

I'll have another look at the changes tonight and will push it then
unless there are more comments from me or others.

You can rebase the patch branch from master to maint.  From Magit, you
can use the magit-rebase-subset command ("rs").  From the command line,
you could do something like

git rebase --onto maint master 

Since in this case the branch only consists of one commit, you could
also just make a new branch off of maint and cherry pick the commit from
the original branch.

In either case, Git will let you know if there are any conflicts you
need to resolve.

I'll merge maint into master.

Re: [O] [PATCH] Fix the single quote printed in the message printed by org-table-edit-formulas

[Kaushal Modi]

Patch (after rebasing to 5a735b0) attached. I hope it works.

Git newbie question:

Making the changes in the maint version of these 4 files manually was a bit
of a pain. What's the right way of porting changes from one branch to
another? I am curious how the changes will be ported from the maint branch
to the master branch. What git command should I be looking at to do this in
future? (because I always use the master branch and if I need to submit a
patch in future, I would need to switch to maint branch and port changes
from my master.

Thanks.

I think it's time to kill the running emacs session and start a new
one. If it happens with the new one, that might be a bug; but IMO it's
more likely that the session has been curdled.

As a followup question, I read the documentation for `org-add-link-type`
which says "Org mode has a built-in default for exporting links." What
is the name of that function? I would like to change Eric's function to
something like:

#+begin_src elisp
  (org-add-link-type "vref" nil
 (lambda (path desc format)
   (cond
((eq format 'latex)
 (format "\\vref{%s}" path))
(t (call org default)
#+end_src

I searched through ox.el but could not find that function.

Thanks,

Alan

This is only scaling in the org buffer. I find high resolution (high
dpi) are often too large in my emacs, so I set this to be something like
300 to 600 to keep the figures reasonably sized in the buffer. It has no
effect on the LaTeX export.

No - I don't want any scaling. They are graphs I have created in R and I
want to conserve the font sizes in the paper.

Setting it to "" works perfectly. I have now set:

--8<---cut here---start->8---
#+BIND: org-latex-image-default-width ""
--8<---cut here---end--->8---

as well as

--8<---cut here---start->8---
# Local Variables:
# eval: (visual-line-mode 1)
# org-latex-image-default-width: ""
# End:
--8<---cut here---end--->8---

I don't know if one is sufficient - I just leave them in and might try
later.

Thanks a lot,

Try:

Re: [O] set default width for figure floats?

[John Kitchin]

Maybe you want org-image-actual-width

This sets teh width in org, if you have a working imagemagick.

org-latex-image-default-width contains the default latex scaling.
Probably you can set this to nil to avoid scaling.

Thank you for the suggestion, but I end up with the same thing as with
the macro: the reference generated is to "fig:log-expt-7", but this does
not work as the label assigned by org to the figure is
"fig:orgparagraph1".

Here is a small example of a similar problem. Exporting this to latex

This is a \ref{fig:foo} and this is a link [[fig:foo]]

#+label: fig:foo
#+begin_figure
Test
#+end_figure

results in

#+begin_src latex
This is a \ref{fig:foo} and this is a link \ref{orgspecialblock1}

\begin{figure}
Test
\label{orgspecialblock1}
\end{figure}
#+end_src

[O] set default width for figure floats?

[Rainer M Krug]

I think this has been asked before, but I can't find it:

Is there a way of setting the default width for images included as

[[file:map-All.png]]

in org documents? It seems that the default is

\includegraphics[width=.9\linewidth]{map-All.png}

and I don't want the images to be scaled, but to let them keep their own
size.

Is this possible (I'd like to avoid having to use #+ATTR_LATEX :width
before each - and even then I would have no idea to unset the value)

Thanks,

Rainer

[O] Latex code inbetween beamer frames

[Giacomo M]

Dear all,
I would like to set a background image for some slides. AFAIK, the way 
to achieve this in beamer is by using sth like:
\usebackgroundtemplate{\tikz\node 
{\includegraphics[width=\textwidth]{mybackpic}};}
before the \begin{frame} of the slide of interest (and after the 
\end{frame}).
I would like to be able to do this in org-mode, and couldn't find a 
solution so far.

Any suggestion would be really appreciated.

Thanks,

Giacomo

I may be missing something but could you not simply use

  [[vref:fig:log-expt-7]]

(along with description text if you wished) and define an org link as
below?

#+begin_src elisp
  (org-add-link-type "vref" nil
 (lambda (path desc format)
   (cond
((eq format 'latex)
 (format "\\vref{%s}" path)
#+end_src

[O] using vref in latex export, and normal links in html export

[Alan Schmitt]

Hello,

I'm converting a latex document into org-mode to easily export it both
to latex and html. I've just encountered something that I don't know how
to do: export a \vref reference. I would like to have something that
exports to \vref in latex, and to a normal link in html.

I thought I could do this trick with a macro:

#+macro: vref @@latex:\myvref{$1}{@@[[$1]]@@latex:}@@

then define the latex command to ignore the second argument:

\newcommand{\myvref}{2}{\vref{#1}}

Unfortunately this does not work, as the name of the label is changed
during export:

Figure \myvref{fig:log-expt-7}{\ref{fig:orgparagraph1}} 

So my question is: is anyone using vref with org-mode? Or should I just
convert this to a plain reference?

Thanks,

Alan
