[GUI Plugin] Modify ePub

Spoiler:

    def _modify_completed(self, job):
        if job.failed:
            self.gui.job_exception(job, dialog_title=_('Failed to modify ePubs'))
            return
        modified_epubs_map = job.result
        self.gui.status_bar.show_message(_('Modify ePub completed'), 3000)

        update_count = len(modified_epubs_map)
        if update_count == 0:
            msg = _('No ePub files were updated')
            return error_dialog(self.gui, _('Modify ePub failed'), msg,
                                show_copy_button=True, show=True,
                                det_msg=job.details)

Edit:
Oops, once more I missed the train, you answered while I was writing ;-)
Maybe it will be better if there is an info_message() instead a error_message, since mod-epub didn't failed at all, it just worked on a perfect epub ;-)...

Yes. The problem is that it could have failed or it could have done no work. At this point it doesn't know which.

I am changing the wording of that message box a bit to make that (I hope) a bit clearer.

[chaley]

This is the new wording.

@lomkiri and @chaley: Thanks for all the work you two put into this. It was really interesting and I appreciate it.

My oops. I left some python 5 (calibre 5) code in the plugin. The file in the first post has been updated. You can get it there or wait for calibre to tell you it is available.

Reasearching this issue with sending docs to Amazon & them now converting ePub's, I have been using this plug-in over the last several weeks to fix the files before I am sending these as personal docs via email - thank you, it works great! With multiple Kindle devices (and using app on iPad), I like emailing personal docs to Amazon as it works very well to keep my reading progress in sync across devices.

However, l am finding that I need to run this more often than not, and wondering if it can be run automatically when I add a book to calibre? I can see how to convert an ePub to an ePub when I add a book but prefer to minimize any changes to original file so have been using this plug-in. I am open to alternate solutions - as a novice this is what has worked for me to date. Very frustrating on first read of a book to find it a mess when I don't run this plug-in.

You could try the Action Chains plugin and create an action chain to do this. Check out the Action Chains thread for more info.

Thank you for posting to the scripts - I was still trying to understand action chains - a bit overwhelming! The scripts in the thread look like a much easier way to get started.

Thank you all - amazing the efforts that go into not just Calibre, but the add-ins also!

Feature Request:
An option under 'Metadata' to remove all 'calibre:user_metadata' meta entries please.

That is already there in the Metadata section: "Remove non dc: metadata elements". Is there some reason that doesn't work for you?

[dragoworld235]

I’ve just discovered this plugin. thanks chaley!

I’m going to use it a lot to remove the metadata added to my epub because my Calibre was misconfigured.

Would it be possible to add an option to remove html comments embeded in an epub pages?

It is possible but I have no interest in doing it. If someone else does the work then I will be happy to release it. Or relinquish maintenance to that "someone".

I suspect that it wouldn't be too hard to do in the editor with search/replace but I haven't tried it.

You don't need to use the book editor's S&R feature to remove a metadata element from an EPUB. Open the EPUB's OPF file (in the book editor), delete the entire element (in this case dc:description) in the code window, and save the EPUB.

If you don't want to 'mess' with editing the OPF code, you can use Sigil's Metadata Editor tool to remove individual metadata elements with the click of a button?

FWIW: I move the text from the Comments column to a Blurb custom column using calibre's Metadata Editor (in bulk via its S&R tool, or cut and paste for an individual book). This allows me to edit Blurb from the book list, and remove it from the EPUB with this plugin.
