Add support for nook

[nookmaster]

Calibre does not detect nook ebook reader, hence not possible to transfer books to it. I attach screenshoot of nook info, if more is needed, please let me know.

[nookmaster]

Thanks for the quick reply. I attach the 2 files, output with no device attached and with nook attached.

[nookmaster]

I forgot to mention that the books are stored in a folder named "my documents" (all lowercase and with a space). I have uploaded a 3rd file with a SD card inserted in the nook.

One more question. Does it create some type of supplementary file for the books after you open them? For instance something along the lines of book_name.mpb?

[kovidgoyal]

Here's a windows build with the Nook driver. Please test. http://calibre-ebook.com/downloads/betas/calibre-0.6.26.msi

[nookmaster]

Thanks for the test file. Unfortunately it does not work, I attach the result of the "calibre-debug -d" output and the folder structure.

I do not see any additional files like mpb on the device.

[kovidgoyal]

Hmm that debug log doesn't make sense. Can you try rebooting your computer once.

[nookmaster]

Same result, I attach the file (I had actually restarted the 1st time as Calibre asked me to).

I see that it blocks for about 30 secons in the "Trying to open device..." stage before it fails.

[kovidgoyal]

OK time for some detailed debugging. Save the attached file test.py and execute it like this

calibre-debug -e test.py

[nookmaster]

It fails straight away (see attachment). Did you attach the right file? The extension indicates Python, but the contents are XML.

[nookmaster]

My bad, forget it, I'll do it again.

[nookmaster]

Sorry for the trouble, I did "save link as" instead of clicking on the download icon and got the wrong stuff. I have uploaded the output, replacing the old file (debug_output.txt).

[kovidgoyal]

Weird, that indicates detection is succeeding. Here's another test

from calibre.customize.builtins import NOOK
n = NOOK(None)
n.open()
print 'Opened at:', n._main_prefix

Save it to test2.py and run it as above.

[nookmaster]

Done.

[kovidgoyal]

There's something weird on your system. Do you have any other e-book reader you can test calibre with?

[nookmaster]

Unfortunately not. I'll try later on at home, on my other PC, to see if the results are the same.

[kovidgoyal]

never mind. found the problem. I've uploaded a build with the fix at the same location as before.

Make sure you download the fresh copy and dont get it from your browser cache

[kovidgoyal]

Fixed in branch trunk. The fix will be in the next release.

[nookmaster]

Excellent, I can confirm that it works. However, I see that Calibre maintains a folder structure for the books I transfer, while the nook does not support folders. Anyway, thats's a different matter. Thanks very much for the prompt updates to Calibre!

[john]

Does it not support folders or does it just ignore them. If a book is in a folder can the device still see and read it?

[nookmaster]

Ok, actually you're right, the book can be read, nook just does not show the folder structure on the memory - everything is shown flat regardless of how it is stored on the device. So the way Calibre does it is just fine.
