EPUB export in Calligra Words

News flash: EPUB publishing is coming to Calligra!

I have long wanted to push Calligra Words as a tool for writing ebooks. It has a simple and intuitive UI that should lend it well to an author's needs. In fact it can remove all the UI elements and just leave the contents on the screen by pressing just two keys: ctrl-h.  Here is a picture of Words in 'author mode' (it's not really called that, but it kind of is anyway):

However there are several other things that we need to implement before we can credibly say that it's good for ebooks. One of them is that there is no way to save to the standard ebook formats.

But today there was a breakthrough in that area! Mojtaba Shahi Senobari (moji) and I have worked on an odt-to-epub filter and today we got the output through the epub validator at http://validator.idpf.org/ for the first time. Here is a screenshot to prove it:

Granted, it doesn't support much formatting, it doesn't support pictures yet and it doesn't split up the contents into chapters. But we have the very basics working and after some cleanup we will push it into the master branch so that others can help out.

If you want to check it out, the branch name is export-epub-moji.
