[Conversion Plugin] KFX Input

[sitrucz]

I was able to import a kfx book, convert it to epub, and view it in Calibre's internal viewer. I make use of folder actions to copy a .mobi, .azw, and .azw3 from My Kindle Content to the auto-calibre folder. This folder tells Calibre to import the book automatically which then I have rules set up to convert to epub etc... My question is when it copies the main file to auto-calibre it doesn't import correctly. Is there a way to look at the name of the file and then go to the My Kindle Content folder and then look for that file there to import?

Trying to do that within this plugin would be messy. It isn't something that I would want to do.

You have a couple of alternatives.

When you find a book in KFX format in My Kindle Content you could zip the content of the book's folder, rename that to have a .kfx-zip extension and put that file in the auto add folder, instead of just the main book file.

Or you could write a new calibre File Type plugin that would be activated when you put something in the auto-add folder and would then perform the actions described above, searching My Kindle Content for a matching book folder, zipping it up, etc.

I'll have to see if I can create an Automator script to zip up the files.

I've wanted to get into plugin writing. I have an infatuation with k2pdfopt and now this file type plugin idea. So, I may look around the forums on where to get started on plugin development. I know Python but definitely not an expert.

Thanks.

i'm using MacOS high Sierra 10.13.4 and have tried to download KFX Input.zip (119.9 KB, 3722 views) trough CALIBRE ''download a plugin from a file''.

No file to open was accessible.

Any idea what should be done to open the right file ?

I recommend downloading and installing via the calibre GUI following the instructions under "How do I install a plugin using Plugin Updater?" in the Introduction to plugins post.

thanks i followed the instruction you gave and have progressed.

However i'm still blocked by DRM.

I need to deDRM the book i bought on Kindle to read it on my KOBO reader.

Is there any simple procedure to follow to solve this issue.

thanks

Before I post to GitHub, I wanted to check on where in the process I'm having a problem. I'm sending a kindle book from my Amazon account to my PC. Then I upload the book into Calibre. However, there's no attached metadata- no title, no author, so it's just generic codes. The book is readable, so technically the import is working, right? Is there a Calibre -> Add Book setting I need to change? It currently converts imports to MOBI. Should it be ePub? Is there a way to make setup for one library and a different one for another library? Or is it a kindle conversion plugin setting I need to change? Thank you very much!

If the book appears to import correctly, but the title is coming out something like "B123456789 EBOK" then you should look under Preferences -> Adding Books that the option "Read metadata from file contents rather than file name" is checked.

If that setting is already checked then the most likely reason for such a title is a failure to import correctly. But that doesn't seem to be the case since the book comes out readable.

If you mean something else by "generic codes" then give an example.

A book in KFX format should import as KFX if successful. A failure to import should result in AZW or KFX-ZIP. If the book imports as MOBI then it is in MOBI format, not KFX and this plugin will have nothing to do with that book.

This is assuming that you have not set "Automatically convert added books to the current output format" in Preferences -> Adding Books -> Adding actions. If you are using that setting then uncheck it so that you can see what format is actually being imported.

Hi jhowell, thanks for the reply! I double checked those two settings, "Read Metadata from file contents" (check mark) and "Automatically convert added book to current output" (unchecked). It's still importing the books with the generic codes like B123456789 EBOK for the titles. Even though the books have those titles, they're all readable in the Calibre viewer. Also, they import as either MOBI or AZW, which seems expected behavior to me. Any other ideas?

[meghane_e]

Here's a clip of the how they import. These were imported AFTER I checked the recommended settings. The newly imported books are readable in Calibre viewer. Thanks!

Since they import as other formats it appears the books you are importing are not KFX. It is likely that this plugin is not related to the problem.

One other thing to check is in Preferences->Plugins->Metadata reader plugins, make sure the "Read MOBI metadata" plugin is not disabled.

It may be possible to find more about what is going wrong by running calibre in debug mode (right-click Preferences->Restart in debug mode) and then importing one of those books. After calibre is closed a log will pop up that you can post for analysis.

Hmmm, I think you're right. Because when you download books to the Kindle reader they're KFX, and so when you copy the files from Kindle reader to PC on USB, they're still KFX. But if you download to the Kindle app on PC [NOTE ver. 1.17.1 for compatible output], it downloads them as AZW and MOBI (rarely HTML). So it is not a KFX plug-in issue! Sorry about spreading my confusion to this thread, lol. At least I'm a bit clearer on what's going on.

You're tips for debugging look helpful, so I'll do that and look for an appropriate thread from there. Thank you so very much for your time responding.

[RESOLUTION!]: It's fixed after my laptop crash, Calibre reinstalled itself, found "Read MOBI data" turned off which was weird. So not sure, but think maybe a plugin conflict somewhere. Thank you!

The python function that returns information about the OS platform is failing for some reason on your system.

That information is only being displayed for debugging. In the next release of this plugin I will have it continue even when this error occurs.
