Kindle Format Cì (10 in the Bai language). Except it's pronounced tsɛ, with a short 'e' like in "meh".

Nope, that's not the chicken chain. has to be KFC or it won't work.

Cool! As I've mentioned, I'm not that interested in converting to KFX, but I am very interested in supporting any development to deconstruct and understand KFX.

I should have more free time in a couple weeks. If there are any specific tests you'd like me to run on my Mac with your new KFX plug-in, please let me know. Happy to help.

Thanks again, jhowell, for all the time and effort you've put into understanding KFX. :

At this point I have decided to just release the plugin and deal with problems as they come up. It will take a day or so to get it ready.

Update: Now released.

It's not working. It crashed java on my Win7 laptop.

I can't find the calibre log file, or I would have posted it.

Thanks for the offer. At this point I'll just wait and see whether any Mac users report problems.

I have added a post to the plugin thread that discusses conversion errors and describes how to capture the error log.

I posted a copy of my log in that thread.

Excuse me for bursting into a thread I have not nearly half enough technical knowledge to provide anything useful to.

I have just discovered that some of the e-ink Kindles got a software update and, unlike with software updates before, this:

In accordance with certain free and open source software licenses, Amazon is pleased to offer an archive file of source code for this software update.

You can find a link to these archive files here:

https://www.amazon.com/gp/help/custo...deId=201630670

Maybe you can find something useful amongst it.

Thanks for the heads-up about the new firmware release.

Amazon is obligated to release source code for some of the open-source software that they use. They do it for each Kindle firmware release. The master list is here.

It doesn't include anything proprietary to Amazon, such as KFX rendering.

Since I have a couple times posted here about having my posts blocked on the KDP forum whenever I mention KFX, I should add that the ban seems to have been lifted. Not only was KFX in the title of the thread, but I was able to use the acronym in my reply to it.

I find it really curious that on the Kindle product pages it doesn't list KFX at all. Under supported formats, it lists: Kindle Format 8 (AZW3), Kindle (AZW), TXT, PDF, unprotected MOBI, PRC — but it's like KFX doesn't exist

I would expect them to list it when it can be created, i.e. when Kindle Previewer 3.0 is released.

I doubt it will ever be an accepted format for submission, because the intent is to reconvert source files to KFX whenever that format or Enhanced Typesetting is updated. Converting from KFX itself would only complicate things.

[DaleDe]

Actually I believe the intent is to somehow untie and disconnect the relationship with ePub. Today KF8 is nothing more than a compiled version of ePub and I believe KF10, rather KFX, is a new format pioneered with AZK and a plan to convert from XHTML to JSON format.

Actually, KF8 is more than just a compiled version of epub as it actually starts the process used in AZK and KFX of extracting sections of text (fragments) from the remaining (mainly common) pieces of the html page (the skeleton) and then these fragments can be loaded on demand using javascript to create a page for azk. Kindleunpack simply reinserts all of these fragments back into their skeletons, recreates the internal and external links, re-inserts extracted svg, rebuilds the ncx, and etc all to make a KF8 look like an epub2 (or in the case of fixed format and epub3).

But once you get to the concept of a base skeleton with fragments inserted (used in the AZK) it is not much of a step to pre-style the fragments, record their relative positioning and create a completely standard single skeleton, and then tokenize to speed processing and save space.
