A better alternative to tex4ht / tex4ebook would certainly be much easier for me, even if I'm still somewhat offended by the intermediate steps. As for xml or pandoc, I'd rather not because I want to keep print (PDF) as the primary output, and I don't want to lose what TeX/LaTeX can do that most markup languages can't. From what I know of pandoc, it is like Sphinx in that the way it generates PDF output is by translating pandoc into LaTeX/TeX, then running TeX! So instead of my current toolchain where I write the LaTeX I want directly, I'd be examining the pandoc output and if it isn't what I want, poking at pandoc in the hope of making things better. It may be unfair, but my impression is that TeX and typesetting / layout systems based on TeX can do more interesting things than say XML or Sphinx. Moving to a more "universal" markup format might broaden my options, but I don't want a lowest common denominator solution. -- cheers, Hugh Fisher ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___

As in my earlier reply, I'm thinking about replacing Adobe Illustrator with
Metapost, and LuaMetaTEX seems to have better integration?

This parser would need to understand TeX source files and conventions
such as % for comments, recognise commands starting with \ and with
arguments/parameters bracketed by [] and {}, and look up command names
that might be written in Lua, then call them.
Isn't that what LuaMetaTEX does? No, I haven't looked at the actual source
code yet, but starting with something that already does most of what you
want is always quicker than writing from scratch.

I'll be trying out Metapost as a replacement. My markup isn't that complicated, so at worst I could translate by hand. But it occurs to me that if I get this markup to markup text translation going, I'd be able to write a LaTeX -> ConTeXt converter as a set of LaTeX named Lua functions. -- cheers, Hugh Fisher ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : http://contextgarden.net ___
[NTG-context] LuaMetaTEX as LaTeX to XHTML/ePub transpiler?
I have documents in LaTeX, and would like to generate XHTML (ePub)
output without going through an intermediate DVI or PDF step.
Markup to markup, translating or transpiling rather than typesetting.
My use case is that I have two tabletop gaming books, 60 - 80 pages
of text and diagrams, written for pdfLaTeX and now with XeLaTeX. I'm
very happy with LaTeX and the wonderful PDF output for print.
But now I also want to create ePub/XHTML as well as print versions.
So far I've tried tex4ebook and tex4ht and neither works for me.
Firstly, some of the LaTeX commands are not recognised or causing
errors.
And secondly, when I managed to get a small test section to work,
the generated XHTML/HTML is very large, full of tiny s. The
problem seems to be that tex4ht runs TeX which typesets everything
into DVI with every element carefully placed on a page, and then
tex4ht tries to reverse that back into HTML. All this extra HTML
will slow down / interfere with the ebook reader which is doing the
final page layout at runtime on a particular device.
How I would like it to work is directly from LaTeX to HTML without
any low level typesetting. If I have a LaTex source paragraph
This is some text with \textbf{some parts} in bold.
The TEX will copy the source text to the destination. If
there's a TeX command, here \textbf, it looks for a Lua function
with that name and invokes it with whatever argument text is present.
The Lua function emits , then recursively processes the argument
text, then emits . Similarly there would be an implied lookup
of \beginParagraph and \endParagraph which would emit and .
Plain text just gets copied through unchanged.
So (finally) my question: is LuaMetaTEX what I'm looking for?
Yes is the answer I'm hoping for. And any guidance would be much
appreciated.
No, but best starting point? I've never tried modifying TeX code
itself, but I am an experienced and sometimes competent programmer.
who has written a compiler parser and a high level code generator.
No and not a good idea to try?
Any other responses?
