DocBook exporter for Org-mode

DocBook exporter for Org-mode

Hello Dominik,

I am a big fan of your wonderful Org-mode, even though I just started to
use it two weeks ago.  I've been using (X)Emacs since 1995, and had
tried to use Muse about 2-3 years ago for note-taking and simple
publishing (i.e. generating LaTeX or DocBook documents from Muse).
However, I remember I ran into some serious limitations (like list
handling, etc.) in Muse and finally gave up on it.  I went back to
writing documentation directly in either LaTeX or DocBook (I use nXML
mode for DocBook editing).

Org-mode impressed me with its nice table editing functionality,
flexible/powerful list support and headline (or section/subsection)
manipulations, and *many* other features.  I really appreciate your work
on this valuable package, and foresee that I will be doing many more
things in Org-mode.

The only thing that is missing (at least to me) in current Org-mode is
the exporter for DocBook format.  DocBook is becoming more and more
popular, so a DocBook exporter in Org-mode could make more people move
to Org-mode.  Also, since there are a lot open-source or commercial
tools to convert DocBook format to almost any other formats (PDF,
PostScript, HTML, XHTML, Text, RTF, etc.), DocBook exporter could be the
main exporter that Org-mode needs to support.

During the last week (mainly during the last weekend), I wrote some code
to export Org files to DocBook V5.0 format, and everything looks very
promising (I have to admit that a lot of work still needs to be done to
make the code complete and stable) .  I am wondering how I can
contribute the code to Org-mode.

I am attaching a PDF file generated from a DocBook XML file that was
exported by my org-export-docbook.el, and would like to get your early
feedback/comments.

There is quite a bit of similarity between org and muse formats.  I've
found that I can edit .muse files in org-mode and stiil publish to
docbook.

Looks pretty good to me.  I'm ready to ty it out!

Re: Re: DocBook exporter for Org-mode

[Sebastian Rose]

docbook is great since it's widely used. 

The output looks good!

How could we test it?
And could we configure it somehow?




Anyway, I'd prefere to export to _one_ XML format from Org-mode and
provide xslt stylesheets to translate between different formats.

That way we all would concentrate on one XML exporter (e.g. the XHTML
exporter) and could provide xslt stylesheets to transform the output.

This would guaranty a slitely more complete and bugfree export, which is
configured from one org-publish-project-alist.

Regards,

   Sebastian

I think we would find hundreds of xslt stylesheets on the web to
transform Docbook to virtually any format.

... google google ...

Opendocument:
  http://open.comsultia.com/docbook2odf/ - toolkit
  http://sourceforge.net/projects/docbook2odf

XHTML
  There seems to be a standard stylesheet included in the Docbook
  distribution for generating XHTML as this mail says (the link in there
  is dead though):
  http://www.stylusstudio.com/xmldev/200012/post30530.html

RTF
  Also included in the standarrd distro

http://packages.debian.org/search?keywords=docbook





Will we loose the features of htmlize.el?
I'm not familiar with the Docbook DTD - I know it includes lots of
elements. How about time/date types, Programming types (string,
variable, class, function....)?

Wouldn't it be easier to transform the XHTML to docbook through xslt?
The types are not lost, since all types that emacs is aware of, are
exported as <span class="type">...</span>.

Yes, this is the power and beauty of DocBook.

I have not tried it, but it seems that syntax highlighting of source
code listing can be done.  See this page:

It should be DocBook -> XHTML if we are talking about general
publishing.  DocBook has enough features, tags, and more importantly,
much more available tools.

Does this know about the fonts and colors I use in Emacs? htmlize.el
does.

...and needs an editor like emacs/Org-mode because there is none :-)

but
A) Most of those tools are simply XML related. XHTML is XML.
B) We have those information the *.org file format gives us. XHTML
   export can display all those.
C) Do you really want to tell a windows user to setup a complete SGML
   system, just to publish to PDF or XHTML?


It's true: Docbook is more general in sense of more non-org-users
might know Docbook, than Orgs XHTML export format.

But for sure more non-org-users will understand the XHTML, than the
Docbook.


I hihgly apreciate the support of Docbook and your effort. Yet, I think
I don't want to publish XHTML through Docbook.

Right now, I have a bunch of org-files, and I get a bunch of XHTML files
as output. Nothing else. No special setup required, no xslt stylesheets,
no FO or saxon.jar in $CLASSPATH (how many users know the contents of
his $CLASSPATH ?), xsltproc, xslt stylesheets, no waiting for a
Java-Application (I prefer C/C++ Tools), no waisted disk space, no
external dependencies.

We can't force end users to use Docbook to get XHTML. Java is _not_ part
of emacs, xsltproc is not part of emacs either (most of this is true for
LaTeX).

The XHTML export _is_ part of emacs and has _no_ external
dependencies. It's results are pages displayed in every browser, even
text browsers.

Docbook is displayed correctly in some of those browsers but only in
conjunction with a stylesheet. But not enough to publish Docbook and
your done. That's why Docbook is hardly ever met in the wild. It's badly
supported by the tools for end users and as complicated to setup, use
and transform as LaTeX (but LaTeX _is_ met in a lot in the wild).



Please don't get me wrong. I really think supporting Docbook is a big
step. I suddenly would have a cool Docbook editor on all the systems I
work on! I'm always happy to see people making such efforts as you
did. And I hope, this will bring more users to emacs/Org-mode too.

I don't think it will use the fonts and colors that you use in Emacs.
The colors seem to be configurable, though.

I am just thinking that by supporting DocBook export we can turn Emacs +
Org-mode into a good DocBook editor, which should be much more powerful
than other GUI-based XML/DocBook editors.

I have to *emphasize* this earlier: I am NOT suggesting that we should
replace LaTeX or XHTML exporters with a DocBook exporter.  Both LaTeX
and XHTML exporters have their good features and I don't think DocBook
can replace them.  DocBook exporter can simply be another addition to
Org-mode, and it can be used by people who need to write DocBook
documents for publishing.  (People use DocBook on both Windows and Unix,
and normally they do not have to know the internal setup of all DocBook
tools.)

Once we have the DocBook exporter, people do not have to know DocBook at
all to write DocBook documents.  All they need to know is simply text
files written in Org format. :-)  The DocBook documents they generate
from Org-mode will be guaranteed to be valid and well-formed.

> I hihgly apreciate the support of Docbook and your effort. Yet, I think

Again, I am not suggesting that we replace current XHTML exporter, which
is a great tool and I can see that people already put a lot of efforts
there to make it very powerful.  DocBook is just an addition.
(Certainly people can use exported DocBook format to generate XHTML
format in some styles different from Org-mode's native XHTML export
result.)

This is understandable.  But generating DocBook documents from Emacs +
Org-mode does not require these things either!  How users use the
generated DocBook XML files for their publishing tasks (including how to
configure and tweak the final PDF format, and how to display them well
as XHTML in browser, etc.) are really up to them; such things are
outside of Emacs + Org-mode!

[To me, within an Org-mode buffer, I can use one key binding to do all
the thing I need: exporting DocBook format, creating PDF and HTML
formats from exported DocBook file, etc.  If I want, I can generate the
info file, man page, pure text format or RTF, etc. at the same time
too.]

We should NOT. :-)

This is nice for XHTML exporter.  The results of DocBook exporter are
not supposed to be displayed directly on any browsers, just like we do
not expect any browsers to display *.tex files from LaTeX exporter.

Neither LaTeX nor DocBook is easy to set up.  While LaTeX is popular in
academia, not so many software companies use it to write software
documentation.

This is my thought too...

Thanks a lot for all the comments!

+1  

I gave up on DocBook long ago. It's pain to author documents in it and
the tools are quite weak.

That why I don't like AsciiDoc as well being based on Docbook tool-chain
and therefore decided to use reST markup which is much lighter, nicely
supported and it can export to many formats (e.g. xhtml, odt, pdf..)

Therefore I'm interested about any hint how could reST be used with
org-mode?

(I'd use muse, but it's not so 'standard' as reST for non-Emacs users.)

Too bad that Pandoc does not have full parser for reST (yet) 'cause it
can convert to both LaTeX/ConTeXt for high-quality pdf output.

Gour

Actually nXML mode has made editing DocBook and other XML files a fun
process.  At least less "painful" than editing LaTeX files to many
people.

It is true that many open-source tools around DocBook are still not
perfect, but they should be good enough for most of the work of most
users.  Some commercial tools exist and are better, but they are not
free.  (I have not used reST, however it does not seem to me that it has
more tools than DocBook.)

I just checked reST markup specifications, and they do look powerful
(but not very lightweight).  Maybe it *is* time to have a standard to
unify all these plain-text based lightweight markup languages: Muse,
Org, reST, asciidoc, all kinds of *wiki*, doxygen styles, etc.  These
languages won't be lightweight and easy to read once they become more
powerful.  At that point, I'd prefer to go back to LaTeX or DocBook.

That may require some code sharing/merging between rst.el and Org-mode,
I guess.  :-)

Well, frankly speaking, I consider that XML simply sucks as authoring
format. I was playing with FOP several years ago and I'd never replace
it with TeX typesetting.

Well, reST is, imho, (similar to markdown), much more readable than XML
with all those brackets.

I do not miss any feature in reST for my writing, the whole Python docs
is written with it and it is for me still much readable in 'source' form
than DocBook.

I knew it must be FOP that you did not like. ;-) I had similar
experience using FOP, and I (and all other team members) had to find
workarounds when hitting problems in FOP (like formatting footnotes in
lists or tables).  Don't know if you have tried XEP from RenderX.  I
have not found any problems in XEP.

I don't think it's bad to use XML as authoring format, even though I
think TeX would still be the ultimate typesetting tool.

Many people who don't like LaTeX can say similar things about LaTeX. ;-)
The main problem with all these lightweight markup languages is that
there is a limitation on their expressing power.  They are perfect tools
for quickly publishing blogs, wikis, simple web sites, documentation of
source code, etc., but will quickly hit their limit when they are used
for more serious publishing.

I don't know much about rst.el, and am still new to Org-mode, so cannot
say much on this. :-)

This is commercial app, right?

It is, and that's exactly why the DocBook export is such a great thing. 

You could say a similar thing about (valid) XHTML, LaTeX, reST -
whatever markup you're not familiar with.

With the DocBook exporter, learning DocBook is reduced to pressing `C-c
C-e' and choose the right option ;-)

And that's one of the reasons I would like a docbook exporter.

I see myself with two usage patterns.  One is where I keep the file in
org (or muse) format, and export to docbook and eventually pdf for
external consumption.  The other is where I use org (or muse) to
"start" the docbook file, and then continue to edit the docbook.  This
is because docbook is so much richer than any wiki format, and I want
to take advantage of what's there.

With the DocBook exporter, I can imagine another usage pattern: we can
use the powerful list, section, and table editing functionality, quickly
edit some paragraphs or sections, export them into DocBook format, and
then include them into other big DocBook files.

How about:

Frankly speaking, Org-mode provides a lot of expressive power if you
want it while still keeping document very readable and nowadays can
produce DocBook output simply by pressing `C-c C-e D' ;-)

I agree about Org-mode's expressive power.

The case for reST is because it's more 'standard' markup for non-Emacs
users. Otherwise, I could continue using Muse as well...

Apart from odt output, I'd be curious to know what reST can do that
org-mode markup and export cannot. Footnotes, tables, hyperlinks,
images---I've found org-mode to be a really great authoring tool for
exporting both to xhtml, ascii, and LaTeX/pdf output. (And, of course,
using latex2rtf, it's trivial to convert the tex files org-mode produces
into files that can be edited in Open Office.)

I wonder if the ascii export from org would be difficult to convert to
reST markup. Section headers and footnotes in the ascii export seem
pretty close to the corresponding markup in reST. Just a thought....

Googling brings up quite some interesting formats supported through
DocBook. These are some of the formats I found on the first glance:

  * ODT
  * SWX
  * (somwhat limited) MSword
  * Java Help
  * Windows Help
  * Entire Websites

I just did a quick search only and I think more intensive search would
reveal many more.

Check Pandoc's features:

"Pandoc is a Haskell library for converting from one markup format to
another, and a command-line tool that uses this library. It can read
markdown and (subsets of) reStructuredText, HTML, and LaTeX, and it can
write markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF,
DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, groff
man pages, and S5 HTML slide shows." 

In the past I also played with: http://txt2tags.sourceforge.net/

I like and plan to learn org-mode to extend the present use greatly, but
similar to Muse, its use is 'limited' to Emacs users while I've need to
share some docs (e.g. writing documentation for software application)
with non-Emacs users, so using more 'standardized' markup is a 'pro'
here.

Dunno more about Asciidoc, but it would be great if Pandoc
(http://johnmacfarlane.net/pandoc/) would have full parser for reST
'cause it represents any supported markup in 'native' state before doing
conversion and it even outputs to Docbook :-)

So, my main point of using reST is more 'standard' and lightweight input
markup with the plethora of output formats.

Gour

Yes, I also think this is a better way of exporting.

The nice thing about org-mode export system is the output-specific
regions (like between begin_latex and end_latex) that allow to stay
working in the org version of your document for more time. Final output
hand tuning is often necessary, but it is nice to push this step back if
possible.

Pandoc is good also, and LaTeX can be inlined as well :
http://johnmacfarlane.net/pandoc/

I wonder wether this can be done using docbook as an intermediate step.

Yes, DocBook has been adopted by many organizations in different areas

On how to set up a DocBook publishing environment, you can take a look
at the following page:

I used xsltproc + FOP before, but now I use Saxon + FOP.

I totally agree!  We only need one XML exporter, and I think DocBook is
the way to go.

How would I implement an individual design for a PDF?
How would I implement an individual layout for XHTML?

Are you shure, we could as easy and flexible style the output, as we can
do now?

I'm quite shure the direct LaTeX output is can't be beaten. I include
some files for LaTeX/PDF output. How would I do that?


Using docbook as the default output means to export from one interim
format to another. This is not bad, but we'll have to convince everyone,
that this is a good thing. The LaTeX and XHTML export (which, by the
way, could be transformed just as good as docbook) work and are widely
used.

Remember, that we will never have more information about the document,
than the Org-file format gives us.

While docbook might be a good technique, I'm not sure if docbook is the
way to go. I started to read about Docbook years ago, but I gave in on
that, since I encountered it in the wild. The DTD is huge and not many
will understand how to use it. XHTML and LaTeX are, what people know
already.
How would we support them in doing their daily work?

I'm not sure sure.  I think docbook is much more content oriented than
LaTeX and xhtml, which seem to be more presentation oriented.  To

Yes...  Once we export the content from Org files into feature-rich

Yes, Muse and Org-mode do have some similarity.  While Muse is mainly
for publishing, Org-mode focuses on many other things beyond some good
publishing functionality.  Since Org-mode already has a very good
publishing framework in its HTML exporter , it is relatively easy (a
small step) to make Org-mode a strong publishing environment too.

I have not used Muse in the past 2+ years.  Don't know whether it has
got much improvement...  It's a nice trick to edit .muse files in
Org-mode. :-)
