3. If all went well, you now have an impressive Org to Org converter.

#+end_src
Obviously, there is not much to see.
It worked wonderful until here.
Now, we're going to redefine `org-translator-paragraph' to properly
ignore one language or the other, depending on `:translator-side' value.
#+begin_src emacs-lisp
(defun org-translator-paragraph (paragraph contents info)
Convert PARAGRAPH to Org, ignoring one language.
Language kept is determined by `:translator-side' value.
(let ((leftp (eq (plist-get info :translator-side) 'left)))
(replace-regexp-in-string
(if leftp \t+.*$ ^.*\t+) contents)))
#+end_src
With a little tweaking, I got rid of errors when running this code.
However, no changes in the output where observable. Finally, I looked
at the output from step 3 above and realized that the parser
normalizes my tab characters away. Only a bunch of spaces in the
output! Ouch!!
So I guess I would need an option on the parser to switch tab expansion off.
I also intended to implement my transformer in a way that I first
define the general org-e-org transformer and then derive a specialized
transcormer by somehow inheriting the general transformer and then
implement my specialized paragraph transformation. It seems that
this is at the moment not possible, but I think it would be good to
think about this, that will make defining new exporters or even
org-file tweakers a breeze.
In fact the problem is subtle. For example, you don't want include
keywords to be expanded and babel block to be executed when exporting
from Org to Org. I've added a noexpand keyword for that. Hence, you
will need to call your converter with:
#+begin_src emacs-lisp
(switch-to-buffer (org-export-to-buffer 'translator *Translation* nil nil nil
nil 'noexpand))
#+end_src
The TAB problem is different. I expand tab early because the machine
creating the parse-tree and the machine exporting it may not be the
same. Tab widths may differ, and it could lead to subtle bugs. I may
add a :tab-width property in the initial environment. I'm not sure
about it yet.
Anyway, your tabs have been replaced with spaces, for now. `tab-width'
of them. Your paragraph translator may then become something like:
#+begin_src emacs-lisp
(defun org-translator-paragraph (paragraph contents info)
Convert PARAGRAPH to Org, ignoring one language.
Language kept is determined by `:translator-side' value.
(let ((leftp (eq (plist-get info :translator-side) 'left)))
(replace-regexp-in-string
(format (if leftp \\{%d,\\}.*$ ^.* \\{%d,\\}) tab-width)
contents)))
#+end_src
Is it better?

Re: [O] Tweaking the export
Hi Nicolas, Thank you very much for taking the time for such a detailed recipe. Today I finally found time to go over it and try to implement my transformer. It turned out to be really easy to get going, but in the end, I hit a roadblock. On 2012-01-29 18:07, Nicolas Goaziou wrote: 3. If all went well, you now have an impressive Org to Org converter.

Hello, Christian Wittern cwitt...@gmail.com writes: For the last couple of years, I have used org-mode more and more for working with and translating texts from classical Chinese. Over time, some special conventions have crept in, like the fact that I like (for the draft translation) to work in a way that has a short chunk of Chinese text on the left and, separated by a tab character, the translation of that piece following on the same line (there are other special conventions like specialized drawers etc., but I don't need to discuss these here now.)

It is possible that English column constitutes a poem and the French column is a line-by-line translation of the column to the left.

Just a side comment: isn't easier to work in 2 different files or buffers (eventually, within the same file) and use some sort of parallel follow-mode? I thought such a thing existed, but can't find it back right now. Anyway, it would be quite easy to implement: it's more or less implementing C-v/M-v so that it's done in two parallel buffers at the same time, instead of just in one!?

Best regards, Seb What you describe is Two-Column mode, and this was suggested by Jambunathan before. I did try this alley, but for me org-mode works better. One of the reasons for this is, that there are some structural aspects that are common to both files. Another reason is that I want to be able grep through the files and be able to see matching lines in both languages -- this helps me ensure a consistent translation. So the current setup is really nice for me for doing the work, but now I need to construct the pipeline for publication. As Jambunathan put it, this is really a problem of tangling the output. BTW, I think the general exporter should also be able to to a org-mode to org-mode conversion. This would provide a general framework to systematically correct little problems in files. I guess here it shows that I am coming from the XML world, where a conversion from one XML file to another XML file with slight alterations of some aspects is a very common pattern.

This should then produce a new org file, that simple has either everything before the tab (the original) or everything after the tab (the translation), while leaving all lines that do not contain a tab character as they are. I also use org mode for translating (from modern Chinese, coincidentally), and as Sebastien mentioned, I find it easiest to split a single file into two subtrees, source and target, then split the window so that I've got the two subtrees side-by-side. You could use follow-mode at this point, though I don't. Selective export then becomes trivial, though you'd have a harder time getting it into a two-column table. It's always annoying to ask how to do something and then be told to do something else, so I'm not going to do that, but I do think you might encounter fewer difficulties making the above setup do what you want, rather than the TAB arrangement. Of course, classical Chinese (particularly poetry) lends itself better to doing discrete chunks one at a time… modern prose would be a nightmare with TABs, though. I've toyed with a home-made follow-type setup, where the two subtrees are displayed in split windows as above, and the sub-headings of the two subtrees have properties pointing to the IDs of their corresponding sub-heading (ie, source chapters are linked to target chapters and vice versa). I got about halfway to implementing something where corresponding paragraphs are highlighted in the non-active window, before getting distracted by an actual translation deadline. (The pie-in-the-sky next step would be to use org-mode to maintain a TMX-formatted translation database (http://en.wikipedia.org/wiki/Translation_Memory_eXchange), and allow for automatic insertion of translations of known terms, a library I expect to have written some time before the obsoletion of Emacs itself.) Anyway, I'm not sure I had much of a point, but if there are any other translators using org-mode, it might be interesting to discuss how we could make it more useful, perhaps in a separate thread.
