The loss of current book highlight isn't critical, and it can be worked around by checking the suppress notify setting. Calibre version 4 is on the horizon, I don't have any insight as to whether it will necessitate any changes to PI's, if it does, whoever makes those changes can have a look at it then.

And if they're inclined, I'd like an option to strip selected dc elements from the opf - e.g, description, subjects, and identifiers.

What I would like to see stripped (if there is another version) is ePub 3 specific code in both the XHTML files OPF.

I frequently use "Modify ePub" and, similar to Stumped, earlier this year began experiencing the non-intuitive annoyance of the screen display always jumping to the start of the book list after I saved the result of the Modify ePub, but I always want to return to the modified book itself so that I can delete the original pre-modified version, and perhaps move to the next book on the list.

Although both approaches suggested by ILoveJedd and BetterRed provide an easy work-around, it still seems a strange and unnecessary glitch. Using the arrow keys (or scrolling down to find the still-highlighted book) works if I'm not distracted by something else and remember what it was I was doing. I'd prefer to not disable the "prompt to save ePubs" functionality because a) sometimes I've made a mistake and decide not to save the modified ePub, and b) auto-saving a problematic modification can have a domino effect by deleting e a prior original version (just ignore this last comment 'b' if not self-explanatory as explaining would just distract from the main consideration). Hopefully there is an easy answer to removing the glitch itself.

You say that as if it’s a simple function. Far from it. I, for one, have no intention of going anywhere near that particular can of worms.

While it’s true that some EPUB 3 books are basically “EPUB 2 with a couple of tiny changes,” many actually take advantage of the enhanced capabilities of the EPUB 3 format. Those simply cannot be automagically downgraded to EPUB 2; such a change requires complex intervention which is far beyond the scope of the Modify EPUB plugin.

So, you can wish for it all you like, but you’d probably have better luck looking for dedicated conversion software or pleading for someone to create an entirely new plugin for that specific task.

Great Plugin! This is very helpful!

But I have 2 more questions about it:
1) Is there a feature to remove html files with a certain name (e.g.: Last-chapter.xhtml)?
2) Is there a feature to change the page progression direction from rlt to ltr inside the opf file?
(changing: <spine toc="ncx" page-progression-direction="rtl">
to
<spine toc="ncx">)
or vice versa (ltr to rtl)?


Thank you so much in advance.

1. No
2. No

But you can ue the Calibre editor to edit these sorts of things since it's very easy to do.

Thank you, I know about this step. But I have more than 700 ePubs and I was wondering if there is a plugin to do them all together automatically as one bulk instead of opening them and changing them manually one by one. Do you know any plugin that can do that?

Appreciated.

As far as I know, this is the only plugin which modify automatically the content of the book (aside of adding jacket or ex-libris) , but I can be wrong.

I haven't been paying much attention to who's maintaining this one lately, but I found a bug in the plugin while working on a private project.

_remove_files_if_exist(), used for 'Remove iTunes files', 'Remove calibre bookmark files' and 'Remove OS artifact files' will only remove the first file found from each list.

Here's a fixed version that removes them all as (I assume) it should work. The change is the addition of a dirtied flag instead of returning immediately on file remove.

    def _remove_files_if_exist(self, container, files):
        '''
        Helper function to remove items from manifest whose filename is
        in the set of 'files'
        '''
        dirtied = False
        self.log('\tLooking for files to remove:', files)
        files = [f.lower() for f in files]
        for name in list(container.name_path_map.keys()):
            found = False
            if name.lower() in files:
                found = True
            if not found:
                for f in files:
                    if name.lower().endswith('/'+f):
                        found = True
                        break
            if found:
                self.log('\t  Found file to remove:', name)
                container.delete_from_manifest(name)
                dirtied = True
        return dirtied

@Bilal93 approached me to add some features to Modify ePub. Which I have.

Bilal93 has asked that I also make a public version containing the added features in case others find them useful.

Features added:

• Add spine rtl - Make sure <spine> tag has attribute page-progression-direction="rtl".
• Remove spine rtl - Make sure <spine> tag doesnt have attribute page-progression-direction="rtl".
• Rename .html files .xhtml - Change any .html files to .xhtml.
• Remove files named - Remove files with any of the names (comma separated) below. Case insensitive.

I also bumped the version number. I leave it up to the community whether these features are worth including in the general release.

EDIT: This version also addresses the _remove_files_if_exist() issue from my previous post.

[Terisa de morgan]

Thank you very much.

[BetterRed]

Works for me on my existing settings, I also checked the html rename option.

Would it be possible to sneak in another feature : if 'Add/replace metadata jacket' is checked allow another option - 'Put jacket at end of book' - and act accordingly

As a general principle I think we should aim to replace the existing version if no adverse issues arise.

[JimmXinu]

I hesitate on that one primarily for the 'slippery slope' factor.

And because my biggest incentive to do it is because the empty space in the 'Jacket' section is unsightly.

[Rev. Bob]

I think I have some “unpretty” mods on my machine that haven’t been merged into a release version yet. I’ll try to take a look in the next couple of days and, if so, splice them into this new edition.

Oh, and it might be worthwhile to add a reciprocal option for that extension change (Change *.xhtml to *.html), and it definitely strikes me as a good idea to include .htm and .xht in the mix. (Standardizing on .jpg/.jpeg would also be handy, and a generalized routine should be able to handle pretty much any “change this extension to that one” configuration.) Granted, that requires some checking for duplicate filenames, but I’d hope you’ve already got that built into the .html to .xhtml routine…

That... is a good point.

Here's a version that also updates <guide><reference> tags pointing to renamed .xhtml files.

EDIT: BTW, yes, .htm is also changed with that option.

And actually, no I didn't do a name collision check. In theory, it would be nice, but seriously, if your epub has chap01.htm and chap01.xhtml in the same dir in the same epub, you have bigger problems.

EDIT2: Implementation rejected by the current maintainer. Test version removed.
