Hello together,

thanks again for the information provided, I am looking forward to the final Mobipocket support.

Until then I am trying to help myself with a File Plugin to convert the files using mobigen. However, since these are my first steps with Python I am a bit lost. I scanned over the forum and found a few hints about how to execut other application from a plugin, however, it does not seem to actually execute, this is the source I am using:

import os, sys
from calibre.customize import FileTypePlugin

class ePubPostProc(FileTypePlugin):
  name                = 'ePub Postprocessing Plugin'
  description         = 'Sets the Language of an ePub File to German and converts it to Mobipocket using mobigen.'
  supported_platforms = ['windows']
  author              = 'Torben Nehmer, Nathan Syntronics'
  version             = (1, 0, 0)
  file_types          = set(['epub'])
  on_postprocess      = True
  priority            = 100

  def run(self, path_to_ebook):
    from calibre.ebooks.metadata.meta import get_metadata, set_metadata
    file = open(path_to_ebook, 'r+b')
    ext  = os.path.splitext(path_to_ebook)[-1][1:].lower()
    mi = get_metadata(file, ext)
    mi.language = 'Deutsch'
    set_metadata(file, mi, ext)
    close(file)

    subprocess.call('"c:\program files\calibre\mobigen.exe" "' + path_to_ebook + '"', shell=True);

    return path_to_ebook

If I execute the command line in question from an arbitary path, everything works as expected.

Given that the conversion from .epub to .mobi works, two more questions: What are the correct calibre API calls for the following tasks:

1. Add the MOBI File as alternative format to the database. I could use the calibredb command line utility, but I suspect that it easier to do it with the API itself.

2. How to find out if the eBook in question already has a MOBI/PRC file in the library to avoid duplicate conversions?


Greetings,
Torben.
