I want to share an upcoming feature in the 0.7.54 release. One complaint I hear often is in regard to the inability to edit ebooks. Many people seem to think EPUB is not a good format for editing. Sigil is often the solution given around these parts but some people insist on the need for a book to be contained in a single HTML file. Simply unzipping an EPUB doesn't accomplish this due to the need to split the files.

To remedy this situation I've added a new output format: HTMLZ. Just like TXTZ it is just a zip file with with a different extension to differentiate it. Inside is a metadata.opf file (calibre can read and write metadata to it). Images are preserved, renamed and placed in an images folder.

Also inside is a single HTML file. Even if you're converting from and EPUB that has been split into multiple parts a conversion to HTMLZ will result in a single HTML file. To go along with this there are a number of ways to configure CSS handling. The default is to place the CSS in separate style.css file. It can also place class based CSS inside of the head element in the HTML itself. Or you can have it write the CSS inline within each element. Finally the last option for CSS is to remove it and convert as much as possible (a very limited set right now) to HTML tags.

As with all of my output format attempts I believe this will have quite a few bugs. Let me know about any issues so I can fix them. I hope people find this useful for their hand editing needs.
