Pandoc (http://johnmacfarlane.net/pandoc/ ) is a document converter. It does a pretty good job of converting a document in one format to another. Pandoc also knows about org-mode now, and can convert an org-file to a Word document! We are going to test it out in this post to see what it does well with.

1 A subsection with some equations

Einstein showed us that \(E = mc^2\).

A matrix looks like this:

\begin{equation} \begin{matrix} a & b & c \\ d & e & f \\ g & h & i \end{matrix} \end{equation}

2 A section with a figure

Here is a figure in the document.

Figure 1: A cosine function.

3 A section with a table

Table 1: A simple table.
x	y
1	1
2	4
3	9

4 Some citations

For fun, a reference to the org-mode book dominik-2010-org-mode.

5 some source code

here is a python block.

print 'hello pandoc'

hello pandoc

and finally, we write a block that will convert this file to a word document.

(save-buffer)
(shell-command "pandoc -s -s org-to-word.org -o org-to-word.docx")

Now, here is that org-to-word.docx

it is pretty good, and blazing fast. The output is not quite as good as the native org to pdf (org-to-word.pdf ), but since the translation is happening outside of Emacs the results are still pretty impressive, and if you need a Word document there is no substitute ¹. The simple equation was translated to a Word equation format (cool!) but the matrix did not show up in the word document, nor did the figure caption. The code does show up, but the lines are not numbered as they are in the pdf. The citation did not work out of the box. The User guide suggests it might be possible to get this to work with a citations extension though.

I am impressed that the Word document has proper section headings. Overall, my impression is that this is a very good way to get 90+% of the way to a finished word document with an org-source file!

Footnotes:

Ok, there is the ODT export engine. So far I have not been able to make that export documents that Word can open though, and it takes more configuration than just installing Pandoc.

Popup tips on bibtex links in org-mode

Posted April 12, 2014 at 02:15 PM | categories: uncategorized | tags:

I want to explore using popup tips to display richer information about org-mode links. The idea is to have something like a tooltip that displays the bibtex entry when you hover over it, or click on it.

https://github.com/auto-complete/popup-el/blob/master/popup.el

Here is a canonical example of a popup.

(popup-tip "Hello, World!")

All I need to do is figure out a simple way to get the bibtex entry as a string, and pop it up when a link is clicked on.

(org-add-link-type
 "test"
 ;; this function is run when you click
 (lambda (link-string) 
   (popup-tip link-string))
 ;; formatting
(lambda (keyword desc format)
   (cond
    ((eq format 'html) (format "<pre>%s:%s</pre>" keyword desc)))))

lambda	(link-string)	(popup-tip link-string)
lambda	(keyword desc format)	(cond ((eq format (quote html)) (format <pre>%s:%s</pre> keyword desc)))

Now we give it a try.

test:show-me-the-popup

That looks good.

Ok, the penultimate step will be to lookup a bibtex entry, and show the entry in a popup. We will hardcode the path to the bibtex file.

(org-add-link-type
 "test"
 ;; this function is run when you click
 (lambda (bibtex-key)
   (let ((entry (with-temp-buffer
                  (insert-file-contents "~/Dropbox/bibliography/references.bib")
                  (goto-char (point-min))
                  (re-search-forward bibtex-key)
                  (bibtex-narrow-to-entry)
                  (buffer-string))))
     (popup-tip entry))))

lambda

(bibtex-key)

(let ((cb (current-buffer)) (entry (with-temp-buffer (insert-file-contents ~/Dropbox/bibliography/references.bib) (goto-char (point-min)) (re-search-forward bibtex-key) (bibtex-narrow-to-entry) (buffer-string)))) (popup-tip entry))

test:mehta-2014-ident-poten

And here is what appears for me:

The final step is to connect this to an idle timer . We want a popup to occur when our mouse is idle. I am setting this up to run one time, after 5 seconds of idleness.

(run-with-idle-timer 5 nil (lambda () (popup-tip "You are being idle")))

[nil 0 5 0 nil (lambda nil (popup-tip "You are being idle")) nil idle 0]

So, we need to setup an idle timer that runs on some interval. When the cursor is on the right kind of link, we want to get a popup. I adapted the following code from http://www.emacswiki.org/emacs/IdleTimers .

;; variable for the timer object
(defvar idle-timer-bibtex-timer nil)

;; callback function 
(defun idle-timer-bibtex-callback ()
  "displays a popup of the bibtex entry in a test link"
  (interactive)
  (let ((object (org-element-context)))    
    (when (and (equal (org-element-type object) 'link) 
               (equal (org-element-property :type object) "test"))
      (let* ((bibtex-key (org-element-property :path object))
             (entry (with-temp-buffer
                      (insert-file-contents "~/Dropbox/bibliography/references.bib")
                      (goto-char (point-min))
                      (re-search-forward bibtex-key)
                      (bibtex-narrow-to-entry)
                      (buffer-string))))
        (popup-tip entry)))))

;; start functions
(defun idle-timer-bibtex-start ()
  (interactive)
  (when (timerp idle-timer-bibtex-timer)
    (cancel-timer idle-timer-bibtex-timer))
  (setq idle-timer-bibtex-timer
          (run-with-timer 1 1 #'idle-timer-bibtex-callback)))

;; stop function
(defun idle-timer-bibtex-stop ()
  (interactive)
  (when (timerp idle-timer-bibtex-timer)
    (cancel-timer idle-timer-bibtex-timer))
  (setq idle-timer-bibtex-timer nil))

(idle-timer-bibtex-start)

idle-timer-bibtex-stop

test:kitchin-2008-alloy

Now, whenever the cursor is on the link, and there is an idle of about a sec, I get a popup window of the bibtex entry. It looks like this:

There are still some limitations to this code. It does not handle multiple citations in a link (like the cite links I normally use do). That will take a little work to fixup. I cannot figure out how to get mouse-over tooltips; this only works when the cursor is on the link. I do not know what the optimal timer setting is. This one runs every second. I do not see any issues in performance with that. Another issue might be making the timer a file local variable. It would be nice if the timer quit running when the file was closed. I do not know how easy that would be to implement, or if there should be one timer running for org-mode. Finally, this code is hard-coded to use my reference file. For a real module, we would probably provide some customization to choose other bibtex files. Overall though, this might be a handy way to quickly peruse the citations in an org-file.

Limitations?

Posted October 19, 2013 at 02:32 PM | categories: uncategorized | tags:

JSON is flexible, and can store text and numeric data. It does not store numpy arrays, but rather it is limited to storing lists of data. You would have to convert them back to arrays if you want to do array math. You probably wouldn't want to store a 3d array of electron density in this format, although it probably isn't worse than a CUBE file format. We haven't tested these files very significantly yet at a large scale to see how fast it is to read from lots of them.

Nonetheless, this looks like a reasonable format to share data in human and machine readable form, without violating the VASP licence conditions.

Exporting accented characters to latex from org-mode

Posted October 03, 2013 at 12:49 PM | categories: uncategorized | tags:

4. Summary.

I noticed recently in writing a technical paper in org-mode that I had some trouble exporting some accented characters to LaTeX.

Here are 5 words that render correctly in LaTeX

1. Jos\'{e}
2. peque\~{n}o
3. Gro\ss
4. Gr\"{u}neisen
5. N\o{}rskov

Here we wrap these words in a LaTeX block so it exports verbatim to see how they look in a PDF.

Note to see this in LaTeX, you must view the exporting-accented-characters.pdf. Now, we use the same characters in org-mode.

Jos\'{e}
peque\~{n}o
Gro\ss
Gr\"{u}neisen
N\o{}rskov

The exported LaTeX code looks like:

\begin{enumerate}
\item Jos$\backslash$'\{e\}
\item peque$\backslash$\textasciitilde{}\{n\}o
\item Gro\ss
\item Gr$\backslash$"\{u\}neisen
\item N\o{}rskov
\end{enumerate}

The exporter does not handle all of them correctly. Org-mode is its own system, and it is not, and won't be a total replacement for LaTeX. Nevertheless, these are pretty common characters for me, and We need a solution! A clunky way we found to solve this is to add a LATEX_HEADER line that defines a new LaTeX command like this:

#+LATEX_HEADER: \newcommand{\gruneisen}{Gr\"{u}neisen}

Then you can use the new command in org-mode. So this text:

We use \gruneisen in a sentence.

Renders like this:

We use \gruneisen in a sentence.

That is not too ideal, since some journals do not like you to define new commands. It turns out that org-mode has its own commands to solve this problem! There is a list of these commands stored in a variable called org-entities.

Here we print these entities for "the record". I add an extra star to the data in org-entities so they will all be nested in this post.

(mapcar (lambda(x)
  "print element x. If it is a heading, add an extra star"
  (interactive)
  (if (and (stringp x) (string= (substring x 0 1) "*"))
      (princ (format "*%s\n" x))
    (princ (format "%s\n" x)))) org-entities)

Based on the last few posts on making links to external files work in the blog, and customizing code block export in HTML, I have rewritten blogofile.elto more cleanly support the use of images and data files in my blog posts. Now, I should be able to include a data file (like this one) in a post and you should be able to click on the link to open it after I publish the post in the usual way by pressing F10. That should process the post, construct URLs for all the links, including images, copy the relevant files to the blog directory, and generate the HTML file for blogofile to build. This is a little more robust than it used to be, as all files are stored in a directory named based on the post title, so there is less concern of using duplicate filenames for images and datafiles.

Here is a gratuitous image, just to see if it works ;)

Hopefully, there is nothing different on the outside! URLs to images are now in a different place, but that should not be apparent unless you read source code. The real difference is that now there are working links to data files! And it is easier for me to write my posts including them, with simple publishing.
