Trouble writing plugin to save MOBI files

wrench100 · 08-16-2018, 01:31 AM

I'm working on a plug-in that includes the option to save the currently selected books as MOBI files to a specific location that varies depending on the book's tags.

I'm having trouble figuring out what class will actually do the save. Is that the SaveToDiskAction class? If so, what are the parameters that it wants?

Thank you

You dont need to use any class to do this. Simply use the copy_format_to() function of the database to do it. The database api is documented in the user manual.

Oh that's great, thank you.

I've got it working as long as I specify a full path to the destination file name. If I give it just a path – path="/Users/wanderer/Desktop" – it throws an error, complaining that I've only given it a path. I see from the docs that this should work. Am I doing something wrong?

I'm on a Mac. The error it's giving is:

IOError:[Errno 21] Is a directory: u'/Users/wanderer/Desktop'

Thanks!

Also, I need to be about to write out the cover to a JPEG file.

Whoops! Silly me, there's a copy_cover_to method right there. Sorry about that.

The docs say you can use a path, by which they mean a path to a file, not a path to a directory.
