ConTexT conversion to html/rtf/odt

ConTexT conversion to html/rtf/odt

[Manfred Lotz]

Hi there,
I'm in a situation where I have to do some documentation which should
be available in html and rtf/odt (would be nice to have).

I do not need any fancy stuff, just simple things: ordered,
unordered lists, verbatim, tables etc.

As a ConTeXt newbie I thought this might be a good idea to get into
ConTeXt. However, I'm not quite sure how to create HTML from ConTeXt.


What I tried so far:

Created a simple document:

\starttext

\section{Some section}

\startitemize[1]
    \item bla bla
\stopitemize

\stoptext    


Tried htcontext test.tex and got:

! Undefined control sequence.
<argument> <dl class="dd-\itemlevel 
                                    ">
\HCode ...ode \leavevmode \fi \ht:special {t4ht=#1
                                                  }\fi 
\a:itemize-group ... {<dl class="dd-\itemlevel ">}
                                                  \global \let \end:dd
=\empty 

\dostartitemgroup ... {\dodostartitemgroup [#2][]}
                                                  \fi 
<to be read again> 
                   \item 
l.6     \item
              bla bla
? 


Perhaps there is some stupidity from my side. If yes I appreciate any
corrections. If no then htcontext from package tex4ht doesn't really
work for ConTeXt and then I would like to know what other alternatives
I have. Also regarding rtf or/and odt.

There is an experimental feature of converting ConTeXt to XML. You can 
then process XML using standard XML tools to get HTML.

Run "context filename". This will create a filename.export file in your 
current directory that looks like this:

<?xml version='1.0' standalone='yes' ?>

<!-- input filename   : back              -->
<!-- processing date  : Sat Nov  6 16:55:02 2010 -->
<!-- context version  : 2010.10.14 13:14  -->
<!-- exporter version : 0.10              -->

<document language='en' file='back' date='Sat Nov  6 16:55:02 2010' 
context='2010.10.14 13:14' version='0.10'>
   <section detail='section'>
     <sectionnumber>1</sectionnumber>
     <sectiontitle>Some section</sectiontitle>
     <sectioncontent>
       <itemgroup detail='itemize' symbol='1'>
         <item>
           <itemtag><math><mrow><mo>•</mo></mrow></math></itemtag>
           <itemcontent>bla bla</itemcontent>
         </item>
       </itemgroup>
     </sectioncontent>
   </section>
</document>

Since you do not need any fancy features, a simpler option is to use 
markdown as your starting format and use pandoc to convert it to context, 
html, and odt. However, creating even slightly complicated tables in 
markdown is a pain, unless your editor supports an ascii table mode.

There is a group of maintainers
(http://tug.org/mailman/listinfo/tex4ht), but the author who was "the
big hacker" passed away not that long ago. You may ask on the mailing
list, but there is no guarantee ...

tex4ht would break each time when Hans does some bigger changes in the
core and this is probably the case now as well.

See Aditya's answer about the rest ...

This is indeed a decent solution, one which worked for typesetting my thesis
in PDF and HTML. (You get RTF and ODT for free, assuming it doesn't take
much glue to get it to look the way you want). I had to write a wrapper
script to do regular expression parsing to take care of edge cases (pandoc
is written in Haskell, so to 'scripting' the application requires working in
that language; my choice was to do a more hackish approach that used a Ruby
script that generated multiple markdown files)

Aditya, do perhaps know one of these editors with ASCII table mode?

! Undefined control sequence.
l.1 \setupbackend
                 [export=yes]

This doesn't work for me. Perhaps my context from TeXLive 2010 is too
old. Not quite sure about that.

Thanks for pointing me to pandoc. On the one hand it works very well
but on the other hand it (markdown) seems a bit too rudimentary.

Not so experimental.
PDF/A was tested (I needs  more testing with new version of AdobeAcrobat)

Yes, can be.
Usually you should use the minimals, but with tlcontrib  --- see
http://tlcontrib.metatex.org/ ---
thigs are changing.

it was added after tex live 2010 was frozen (this year we froze rather 
early not knowing that there would be a long delay before 2010 showed 
up; also we had to freeze in sync with luatex)

Emacs org mode. Nothing else even comes close to it. There are a few 
scripts that will convert csv to similar to rst tables.
