Using dictionaries purchased from Kindle Store

[qys]

I wonder if it's possible to use a dictionary purchased from the Amazon Kindle Store (for example, this one) in KOReader. It looks like the dictionary downloaded to my Kindle is in some "azw" format, not the "stardict" format KOReader supports. However, the stock reader in Kindle supports the "azw" dictionaries in "Settings > Language & Dictionaries > Dictionaries".

How do I convert "azw" to "stardict"? What are these "azw" files anyway, a generic format for e-books, or a specialized format for dictionaries?

you can try pyglossary

I've actually managed to pull it off and I have written a manual for my future self. However I won't be at home until next week. If you remind me about it next weel then I'll post the instructions here.

I've also managed to get Rakuten Serif font to work in Koreader lol.

Thanks Ebookus for suggesting pyglossary; that looks promising!

DJUNGELSKOG, please post the instructions once you have time! I'm sure many people like me will benefit from this.

Ok here we go.

I was looking to achieve the same thing and eventually I've found these instructions: https://gist.github.com/Fef0/913caa8...0ed1eb9d0f11e7 . They didn't work for me initially so I have amended them.

Step 1:
Download the KindleUnpack program from here: https://github.com/kevinhendricks/KindleUnpack
Start GUI with python ./KindleUnpack.pyw
Select .mobi file as input and choose your output directory
(optional) I don't know if it is necessary, but select ePub Output type: Auto-Detect
Click the Start button and wait
A file called mobi7/book.html is now present in the output directory

Step 2
Download the mobi2stardict.py script from here: https://github.com/anezih/mobi2stardict
Place the script in the same folder as the book.html file
Run it with
python mobi2stardict.py --fix-links --dict-name "vandale-nl-nl" --textual --html-file "book.html"
A file called book_stardict_textual.xml will appear

Step 3
Download PyGlossary https://github.com/ilius/pyglossary
Select input file book_stardict_textual.xml
Select input format stardict_textual_file (.xml)
Specify the ouput file /home/schatje/Downloads/dictionaries_to_convert/name_of_ur_file
Specify the output format StarDict.ifo

Step 4 (optional, KOReader on Kindle)

(optional) If you want to change the dictionary name (it is book by default) then open book.ifo with a text editor and update "bookname" entry to bookname=wordnet3
Copy ALL the files (book.dict, book.idx, book.ifo, book.syn) to koreader/data/dict/
Restart KOReader
From KOReader select the magnifying glass > Dictionary settings > Manage dictionaries > and select wordnet3

I'm very happy with the result! Maybe there is an easier way to achieve the conversion but I didn't look for it.
