[Conversion Output] KFX Output

[steakhutzeee]

Question, Wine-wow64 is available https://gitlab.winehq.org/wine/wine/-/releases/wine-9.0. In my tests I installed that for the limited number of dependencies. But the KFX Output looks after the wine64 executable.

Could be possible to let the plugin work with Wine-wow64 also?, so also with the single wine command that in this version replaces the wine64 command?

I don't know, maybe a symlink wine -> wine64 would suffice? I'm not sure.

That's frustrating, but thanks. Do you have any inkling as to why it's happening or what I can try in order to fix it? It's very annoying as it was working fine and just stopped a few days ago.

Out of interest, I'm aware that the plugin is only tested up to Kindle Previewer 3.84, and I've already tried installing various versions of this, but what is the best way to install a previous version? I think I just googled "Kindle Previewer 3.84 download" and found this https://www.filepuma.com/download/ki..._3.84.0-40034/. Maybe there's a better way?

Maybe try with a different version of Kindle Previewer. I have to try that under Wine.

Annoyingly I've tried multiple versions of Kindle Previewer as mentioned in my last post right above this one. Did you ever manage to get this error fixed or are you still struggling with it?

I have no idea. It works fine for me under Windows 11.

I have actually tested it with the latest Kindle Previewer version (3.87.0). I updated the documentation in first post in this thread to reflect this.

I have used the Internet Archive Wayback Machine and UptoDown to locate some old versions. However I cannot vouch for the integrity of the files downloaded from those sites.

I will change the plugin to look for both "wine64" and "wine" in the next release.

No worries. I guess all I can do is keep trying. I don't suppose you know if there's a way to convert files to KFX without using the plugin, for example, maybe there's a way of converting to KFX by directly using the Kindle Previewer?

Apologies for messing up the formatting above. Won't let me edit annoyingly. Hopefully you're still able to read my question.

KFX Output isn't doing the conversion, it is using command line interface of Kindle Previewer. So presumably you can use that too.

There is a more complex alternative process. You can use the regular graphical interface of the Kindle Previewer to open an EPUB and then after it displays you can export a KPF file. That file can then be converted to KFX using the command line interface of this plugin. See the first post of this thread for details. (However given that the Kindle Previewer appears to be failing when invoked by the plugin I suspect that it will also be unable to produce a KPF file when run manually.)

Or you can use one of several send-to-kindle methods supported be Amazon, including a web site. That will deliver KFX format in most cases but it requires your device to be online with Amazon.

Other then the Wine-wow64 argument. Is it possible to point to Kindle Previewer installed in a Wine custom $WINEPREFIX?

From my previous tests I see that the plugin looks for the 'Exception('Wine registry file /home/steakhutzeee/.wine/user.reg' file. I'm new to Wine so don't know if this file is unique or if it's present in any WINEPREFIX.

EDIT: Yes it looks that any WINEPREFIX has its user.reg file. From https://wiki.winehq.org/Bottling_Standards I can see:

Winetrick's current approach is a good foundation. Every prefix includes a file named wrapper.cfg (at the top-level of a prefix next to user.reg), which stores the prefix's longer title. Then whenever a new verb is installed in a prefix, metadata specific to the verb is registered in a new file, according to the convention current_prefix/verb_category/verb_name.vars

Maybe an option could be added to the plugin to specify the WINEPREFIX dir? And if left unspecified it will use the default in /home/user/.wine?

Thanks!

I have the opposite problem - after conversion to kfx, all hyphenations disappear. I added them using the polish books/hyphenate this plugin and they work fine in epub, but not after I convert it to kfx. Is there any way to fix this?

KFX format does not support soft hyphens as added by those plugins. Instead it uses built in hyphenation dictionaries for Kindle supported languages, which does not include 'Polish.

Pa @jhowell Unless something changed in last ~6 months your statement about KFX renderer on Kindle devices not supporting soft hyphens is 100% incorrect. Sometimes after Amazon started using KFx format for PDOCs send via Send to Kindle web app I've tested the idea of sending soft hyphenated epub book in serbian language and the end result was a KFX file that had hyphens in the correct places.
If I would send the same book but without added soft hyphens the delivered KFX wouldn't have hyphens.
It's also curios how unlike Kindle Previewer that refuses to convert to KFX books in serbian (since it is not officially supported language) "cloud" conversation pipeline doesn't care about the language and creates a KFX file (normally without hyphenation since the firmware doesn't? include hyphenation dictionary for serbian language).


So, in conclusion: the same approach that worked in the past for getting hyphenated azw3 file via Send to Kindle also worked for KFX... at least the last time I've tested it in both Kindle for Android and Kindle PW5.

I did not know that. Thank you for the update.

Perhaps Ruby Dragon can provide a sample file that exhibits the problem for further analysis.
