New Exporter html - latex - beamer

New Exporter html - latex - beamer

[Robert Eckl]

Both, the old and the new Exporter are brilliant tools, migration to the
new exporter didn't make great issues.
I have to provide weekly newsletters in the format pdf and html. Up to
now i did this with exporting to scrartcl, known as koma-script.
Including images is a bit booring because i handle two formats, for example

#+BEGIN_SRC Org
#+BEGIN_LaTeX 
  \begin{window}[0,r,\href{http://www.link.de}{\includegraphics[width=0.28\textwidth]{path/picture}},{}]
  \begin{comment}
#+END_LaTeX
#+ATTR_HTML: alt="Objekt" title="Objektansicht" align="right" width="30%" padding="0em" padding-top="0em"
[[http://www.link.de/][http://www.link.de/path/images/picture.jpg]]
#+BEGIN_LaTeX
  \end{comment}
  \parbox{0.7\textwidth}{
#+END_LaTeX
  Any Text
   - item 1
   - item 2
   - item 3
#+BEGIN_LaTeX
  }
  \end{window}
#+END_LaTeX
#+END_SRC

It works, but it's a bit boring. The parbox only is required with
lists.
Now i plan to use Beamer, possible instead of scrarctl. 
If I use BEAMER_col the titles ignored by beamer will exported in html -
format.

Perhaps someone can give me a hint how to deal with this, perhaps 
 - a comment-environment for HTML how i used for LaTeX or
 - write the BMCOL-Environment manually in an LaTeX-Block?

TIA,

Robert

This is not even a decent answer, but in a pinch you might define a
yasnippet for this.  (A decent answer would be to use some kind of a
preprocessor, a good answer would be to use a preprocessor in Elisp,
and the best answer would include its code;).)

I am not sure what your latex bits are trying to accomplish so it's
difficult to advise on how to achieve what you want.  Maybe wrapfigure,
which org export supports (float option, I believe, but I am not sure),
is what you need instead of "window"?

The latex bits are doing what they should. |-----------------------------|
I don't want the image floating, because   |                             |
the text regularly is small. The image     |                             |
will be placed how you can see here.       |-----------------------------|
Here the text goes over the complete line - If I'm using a list i have
to put it in a parbox. The environment window is provided by package
"picinpar", seems that it not works within beamer.

Perhaps for this yasnippet as recommended from Marcin would be usefull.

OTOH i would like to use beamer in future, Beamer_Col does a similar
job, except of surrounding the image with text. Does Beamer provide
something like this?

But, if i write the text for Beamer-Output, i have to handle html-output
extra. The LaTeX-package "comment" isn't provided by beamer, I don't
know neither how to comment out the HTML-Code for LaTeX-Beamer-fragments
nor how to comment out Beamer-Fragments für HTML-Export.

Seems, Beamer+html is much more complicate than Beamer+scrartcl/article.

Thanks,

Robert

You might be able to do what you want with filter functions.

Suppose you start with this:

(Note: long lines might have been wrapped.)

,----
| #+ATTR_HTML: alt="my altname" title="my full title" align="right" width="30%" padding="0em" padding-top="0em"
|[[http://my.com][my place.jpg:windowenv:]]
| More stuff
| - item 1
|   - item 1.1
|   - item 1.2
| #+LATEX: } \end(window}
`----

and want to get this from latex export:


,----
|
\begin{window}[0,r,\href{http://my.com}{\includegraphics[width=0.28\textwidth]{my place}},{}]
| \parbox{0.7\textwidth}{
| More stuff
| \begin{itemize}
| \item item 1
| \begin{itemize}
| \item item 1.1
| \item item 1.2
| \end{itemize}
| \end{itemize}
| } \end(window}
`----

and this from html

,----
| <p>
| <a href="http://my.com" alt="my altname" title="my full title" align="right" width="30%" padding="0em" padding-top="0em">my place.jpg</a>
| More stuff
| </p>
| <ul class="org-ul">
| <li>item 1
| <ul class="org-ul">
| <li>item 1.1
| </li>
| <li>item 1.2
| </li>
| </ul>
| </li>
| </ul>
`----

You can do that with this filter:

,----
| #+BEGIN_SRC emacs-lisp
|   (defun filter-links-windowized (link backend info)
|     "Rid :windowenv: from LINK desc and format per BACKEND. Ignore INFO."
|     (let ((clean-string (replace-regexp-in-string ":windowenv:" "" link)))
|       (if (eq backend 'latex)
|           (let ((wprefix "\\begin{window}[0,r,")
|                 (wpostfix"}},{}]\n\\parbox{0.7\\textwidth}{")
|                 (repstrng 
|           "\\1{\\\\includegraphics[width=0.28\\\\textwidth]\\2}"))
|             (concat wprefix
|                     (file-name-sans-extension
|                      (replace-regexp-in-string 
|                       "\\([^}]*}\\)\\({.*}\\)" 
|                       repstrng
|                       clean-string))
|                     wpostfix))
|         clean-string)))
| #+end_src
`----


which you install with this line:

,----
| #+begin_src emacs-lisp :eval never
|   (add-to-list 'org-export-filter-link-functions
'filter-links-windowized)
| #+END_SRC
`----

Then run the new exporter.


What you want yas to provide is something like

,----
| #+ATTR_HTML: alt="" title="" align= ...
| 
| #+LATEX: } \end(window}
`----

if you like to use C-c C-l to enter the link - just remember to add the
:windowenv: after the link description.

or 

,----
| #+ATTR_HTML: alt="my altname" title="my full title" align= ...
| [[ ][  :windowenv:]]
|
| #+LATEX: } \end(window}
`----

if you don't use C-c C-l.


HTH,

Chuck

You can fake what you want using columns and blocks.  See attached
example, both org and pdf.

Yes, this is a problem.  There is no easy way to select elements for
export other than whole sub-trees (using tags as in :noexport:).
I'm sorry I can't advise on this.  I don't tend to export to more than
one target for any given document.  I write with the intention of
exporting to latex (PDF) or html but not both from the same document.

Replace this line:

with these:

      (if (and
           (eq backend 'latex)
           (string-match ":windowenv:" link))

My response is very late, sorry.

Thank you for your effort and the code. I'll try to use it, sounds good.
Reading from filters on worg didn't give me any idea how to use it, 
but your code and explanations seems a good entry.

Perhaps later i'll try to adapt that functionality to the parallel
beamer/html-export. 

Cu,
Robert
