ANN/RFC: ox-epub

[Mark Meyer]

Hi,
this is to announce that ox-epub is now in a somewhat working state and
pretty much aligned with the rest of the ox framework.

https://github.com/ofosos/ox-epub

The current release is 0.2.1 which is right now syncing to MELPA stable.

If you want to generate EPUB directly from org mode, please give it a
spin. The output should always be reasonable and readable in an ebook
reader, but I'm also interested in a more formal way of checking
correctsness. So if you're at it, you may try
https://github.com/IDPF/epubcheck which will give you a detailed listing
of problems with the generated epub.

If you or epubcheck find any reason to complain, please don't hesitate
to open a bug on github, or by directly mailing to me. Please attach any
relevant data, in general the output of epubcheck might be sufficient. I
will try to solve any issues without requesting your data.

Hope you like it.

Cheers, Mark

Hi Mark,

I can't say I have much need for ePub exporting right now myself, but
congratulations on putting this together, looks like great work!

This is great! I don't have time to test-drive it right now, but I definitely
will before too long.

Thanks

Hi Mark,

this sounds potentially very useful (to me, at least).  Will it export
equations and tables, even if as images?  I guess I could simply try
it... which I'll aim to do this week.

thanks,
eric

Tables should be no problem. Equations I'll say are not supported. I'd
assume you want MathML support, this was delivered with EPUB 3.0.1,
while we're currently targeting EPUB 2.0.1.

Let me look into that.

Cheers, Mark

epubtest.org is something aking to an exhaustive test of feature
compliance of reading
systems. http://epubtest.org/testsuite/epub3/feature/mathml/ details the
MathML support for these devices. It looks kind of discouraging.

Now most readers support some kind of JavaScript, but that support is
not clearly specified in the standard. So using MathJax may be possible
on some devices, but not on others.

I'll keep looking on how to best implement this.

Cheers, Mark

Probably the default solution should be images.  Do you think svg images
would be an option?  From here it seems it might generally work for at
least epub-3.

    http://epubtest.org/testsuite/epub3/feature/image-embedding/

We can produce svg images with dvisvgm already, cf.

    http://orgmode.org/org.html#Math-formatting-in-HTML-export

Is it possible in epub to specify fallback rendering options like in HTML?
If so it might be possible to put in both an MathML rendering and an svg
image.

Thanks,
Rasmus

I will look into Image Export.
