 Hi,

 First my previously pasted :exports code will throw errors on

  :exports (if (and (boundp 'latexp) latexp) code results)

 As for placing latex headers in a latex code block, I don't believe that
 is currently possible.  I do agree it would be nice for latex code
 blocks to inherit latex headers from the containing Org-mode buffer but
 that would be a non-trivial piece of development, which I just don't
 have time for at the moment.

 I've just added a :headers argument which should allow changing things
 like fonts that need to take place in the headers portion of the latex
 file.  See the following examples, passing both a single header and a
 list of headers.

 --8---cut here---start-8---

 #+begin_src latex :headers \usepackage{lmodern} :file name1.pdf
  Eric Schulte
 #+end_src

 #+results:
 [[file:name1.pdf]]

 #+begin_src latex :headers '(\\usepackage{mathpazo}
 \\usepackage{fullpage}) :file name2.pdf
  Eric Schulte
 #+end_src

 #+results:
 [[file:name2.pdf]]
 --8---cut here---end---8---

 Please pull this down and let me know if it works for you.


Just pulled, make clean  make  make doc  make install. Tried it and I
get the default font for the first and Palatino for the second, but the
lmodern is not appearing to change what's going on. I tried what usually
works for me:

\renewcommand{\rmdefault}{cmss}

and this did not work to make it sans serif. Am I doing something wrong?


Thanks,
John

Re: [Orgmode] TikZ to separate file (babel?) possible?

2010-10-28 Thread John Hendy 
Eric,


Just retried and was able to get it to work. Perhaps someone should add this
to the ob-doc-latex page? For reference, I tried each of the following:

Works: 1) #+begin_src latex :headers \renewcommand{\rmdefault}{cmss}

Doesn't work: 2) #+begin_src latex :headers
'(\\renewcommand{\rmdefault}{cmss})

Works: 3) #+begin_src latex :headers '(\\usepackage{mathpazo})

Which was puzzling me about #2 which led me to try:

Works: 4) Doesn't work: 2) #+begin_src latex :headers
'(\\renewcommand{\\rmdefault}{cmss})

Note the second double backslash before rmdefault. That escape character was
necessary there, too.

Thanks for the help on this!! It's *perfect*.

Re: [Orgmode] TikZ to separate file (babel?) possible?

2010-10-25 Thread John Hendy 
Followup question. I have an existing diagram I had already exported to PDF
via LaTeX, taken a screenshot of, and used in a presentation. I tried the
same diagram with the new method and am having issues with the font. The
original org file is like this:

*---( File_1.org - embedded LaTeX )---*
#+latex_header: \usepackage{tikz} \usetikzlibrary{shapes,positioning,arrows}
#+latex_header: \usepackage[hmargin=2.5cm,vmargin=2.5cm]{geometry}
#+latex_header: \usepackage{lmodern}
#+latex_header: \renewcommand{\rmdefault}{cmss}

* Section

#+begin_latex

+++ TikZ code is here +++

#+end_latex

*---( End File_1.org )---*


My file using this new method is like this:

*---( File_2.org - exports TikZ to separate PDF via babel/LaTeX )---*
#+latex_header: \usepackage{tikz} \usetikzlibrary{shapes,positioning,arrows}
#+latex_header: \usepackage[hmargin=2.5cm,vmargin=2.5cm]{geometry}
#+latex_header: \usepackage{lmodern}
#+latex_header: \renewcommand{\rmdefault}{cmss}

* Section

#+begin_src latex :file flow-chart.pdf :packages '(( tikz)) :border 1em

+++ TikZ code is here +++

#+end_src

*---( End File_2.org )---*


In my first file, the entire font is latin modern (sans-serif). Header,
title, author, *and* all TikZ diagram text.

In the second, only the header is (if I export the whole thing), but not the
text in my TikZ nodes. Why is the babel block ignoring the document font
setting?


Thanks,
John

 For completeness (and the mailing list archive), if you need to do
 this directly in latex, you will want to use the minimal document
 class and the preview package.  Check out examples on the tikz
 examples web site [1].  The preview package is what babel uses.

Code = raw LaTeX/TikZ code? If so, I don't really care about that. i just
want the graphic.


 This is possible by adding the following header argument to the code
 block which will evaluate the latex block when the export target is not
 latex and will just export the code when the target is latex.

  :exports (if latexp code results)


When trying C-c C-c after adding this, I get Symbol's value as variable is
void: latexp in the minibuffer.

Also, does this assist with my font issue? My main question is how to get
the document font to apply to my babel block. At present, the code shown
above for file_2.org is *perfect* in its behavior (I get a perfectly cropped
PDF of my diagram) except for it not being the right font. I just need to
know to set the font for the TikZ babel output.


Thanks for the assistance,

Re: [Orgmode] TikZ to separate file (babel?) possible?

2010-10-25 Thread Eric Schulte 
Hi John,

In the case you describe I would export the *code* of the tikz latex
block rather than the file resulting from evaluating the block.

This is possible by adding the following header argument to the code
block which will evaluate the latex block when the export target is not
latex and will just export the code when the target is latex.

  :exports (if latexp code results)

 Followup question. I have an existing diagram I had already exported to PDF
 via LaTeX, taken a screenshot of, and used in a presentation. I tried the
 same diagram with the new method and am having issues with the font. The
 original org file is like this:

 *---( File_1.org - embedded LaTeX )---*
 #+latex_header: \usepackage{tikz} \usetikzlibrary{shapes,positioning,arrows}
 #+latex_header: \usepackage[hmargin=2.5cm,vmargin=2.5cm]{geometry}
 #+latex_header: \usepackage{lmodern}
 #+latex_header: \renewcommand{\rmdefault}{cmss}

 * Section

 #+begin_latex

 +++ TikZ code is here +++

 #+end_latex

 *---( End File_1.org )---*


 My file using this new method is like this:

 *---( File_2.org - exports TikZ to separate PDF via babel/LaTeX )---*
 #+latex_header: \usepackage{tikz} \usetikzlibrary{shapes,positioning,arrows}
 #+latex_header: \usepackage[hmargin=2.5cm,vmargin=2.5cm]{geometry}
 #+latex_header: \usepackage{lmodern}
 #+latex_header: \renewcommand{\rmdefault}{cmss}

 * Section

 #+begin_src latex :file flow-chart.pdf :packages '(( tikz)) :border 1em

 +++ TikZ code is here +++

 #+end_src

 *---( End File_2.org )---*


 In my first file, the entire font is latin modern (sans-serif). Header,
 title, author, *and* all TikZ diagram text.

 In the second, only the header is (if I export the whole thing), but not the
 text in my TikZ nodes. Why is the babel block ignoring the document font
 setting?


 Thanks,
 John

Re: [Orgmode] TikZ to separate file (babel?) possible?

2010-10-22 Thread Erik Iverson 

John,

Does
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-LaTeX.php#sec-4_2
help?  There is a tikz example there.  The :file argument may be all
you're missing, and putting your code in a latex source block.

Here is what I do when I have an R code block that generates
LaTeX code.  Hopefully this can be adapted to your case.

#+srcname: R-latex
#+begin_src R :results silent :exports code
  lf - function() {
  \\LaTeX
  }

  lf()
#+end_src

#+begin_src latex :noweb yes :file (if (and (boundp 'htmlp) htmlp) 
latex-logo-html.png latex-logo.png) :buffer (if (and (boundp 'htmlp) 
htmlp) no t)

R-latex()~is a high-quality typesetting system; it includes
features designed for the production of technical and scientific
documentation. R-latex()~is the de facto standard for the
communication and publication of scientific
documents. R-latex()~is available as free software.
#+end_src

That messy :file and :buffer arguments needs some explanation.

They are there so that when I eval the code block *in* an org-mode
buffer, with C-c C-c, that an image will be generated to be
inserted into the buffer.  However, this uses my background color
in emacs, which I don't actually want when exported to HTML, that's
what the :buffer argument controls.  Essentially, it's just
what arguments get passed to dvipng (if I recall correctly).

On Latex export, the actual latex code should be included in the
document, so I think all of my use cases are covered.

The only issue is that org-mode doesn't display PDFs generated
from a :file argument in buffer, but you might not care about
that.

If you're an R user, you might also check out the tikzDevice package:
http://r-forge.r-project.org/projects/tikzdevice/

HTH,
--Erik

Hi,


I've recently gotten into TikZ and love it. It is simply fantastic for 
creating neat diagrams and other thingies.


One question... I created an org file with a flow chart in it and simply 
put my TikZ code in between #+begin_latex and #+end_latex. This is fine 
when the picture is in a document, but what if I want just a 
.png/jpg/eps/pdf output? Is it possible to use babel or something else 
so that I can simply generate a picture vs. needing it to be in the 
PDF output?


I can ask the PGF list as well, but this one is far more active and I 
know some use TikZ here. I ask because sometimes in my notes I'd like to 
have the code present but also be able to reuse my work elsewhere, like 
when I have to present using powerpoint. It'd be nice to just grab the 
picture (like what I do with gnuplot output) rather than generating a 
pdf just for the TikZ pic, screenshot or gimp it down to size, and then 
be able to use it.


Does that make sense? It seems like babel would be perfect for this. It 
already allows all the typical handles -- file output, what to export, etc.


Or does this already exist and I'm ignorant?


Thoughts?
John

Re: [Orgmode] TikZ to separate file (babel?) possible?

2010-10-22 Thread Eric Schulte 
Hi John,

I use blocks like the following to create standalone pdfs.

#+begin_src latex :file stuff/epr-logo.pdf :border 1.75em :packages '(( 
tikz)) :exports none
  \usetikzlibrary{shapes,arrows,shadows,decorations,decorations.text}
  \tikzstyle{line} = [draw, ultra thick, -latex']
  {\huge
\begin{tikzpicture}[scale=0.5]
  \path
  [decorate,
  decoration={text along path,
text={main(int argc, char *argv[]) int a; int b; if(a!=b) a++1;}}]
(0,2) cos (3,0.5);
\path
[decorate,
decoration={text along path,
  text={argc, char *argv[]) int a; int b; if(a!=b) a++1;}}]
(4.5,-0.5) sin (8,-2) cos (12,0) sin (16,2) cos (19,0.5);
  \path
  [decorate,
  decoration={text along path,
text={main(int argc, char *argv[]) int a; int b; if(a!=b) a++1;}}]
(0,-2) cos (4,0) sin (8,2) cos (11,0.5);
  \path
  [decorate,
  decoration={text along path,
text={[]) int a; int b; if(a!=b) a++1;}}]
  (12.5,-0.5) sin (16,-2) cos (20,0) sin (24,2);
  \path
  [decorate,
  decoration={text along path,
text={if(a!=b) a++1;}}]
  (20.5,-0.5) sin (24,-2);
  \end{tikzpicture}
  }
#+end_src

I then normally use the convert command if I want to change the
resulting pdf into a png or other image type more suitable for web
publishing.
