Calibre v8.0 kepub features?

[.tycho]

Hey everyone, just wondering, did hyphenation change or break in 8.0.1? I'm curious because I copied my hyphenation settings from the KTE plugin to the built-in KT plugin, and now my KEPUBs are no longer hyphenated.

I've attached my settings in Calibre's KoboTouch driver. Any thoughts? Thank you!

the settings insert the exact same css as the KTE driver did, open one of the files sent to the device and check for yourself.

Ok, so I must admit, I'm approaching the limits of my understanding of EPUB file structure. But I opened the KEPUB file contents, and I don't see a hyphenation.css file present. I think that's the one that contains the hyphenation settings, right?

Thank you for helping me with this!

Not it adds the CSS to a <style> tag in each HTML file. So open one of the HTML files and look there. The KTE driver used ot create a separate css file, the new code doesnt.

Ok, so I opened one of the chapter HTML files, and the only reference to hyphenation I see is:

<style type="text/css" id="kobostylehacks">div#book-inner { margin-top: 0; margin-bottom: 0; }


* {
    /* Vendor-prefixed CSS properties for hyphenation. Keep -webkit first since
     * some user agents also recognize -webkit properties and will apply them.
     */
    -webkit-hyphens: auto;
    -webkit-hyphenate-limit-after: True;
    -webkit-hyphenate-limit-before: True;
    -webkit-hyphenate-limit-chars: True True True;
    -webkit-hyphenate-limit-lines: True;

    /* CSS4 standard properties for hyphenation. If a property isn't represented
     * in the standard, don't put a vendor-prefixed property for it above.
     */
    hyphens: auto;
    hyphenate-limit-chars: True True True;
    hyphenate-limit-lines: True;
    hyphenate-limit-last: page;
}

h1, h2, h3, h4, h5, h6, td {
    -webkit-hyphens: none !important;
    hyphens: none !important;
}
</style>

The -webkit-hyphenate... settings just state True, instead of the numbers in the KoboTouch settings? Again, I could be totally missing it. Thanks!

Thanks but I don't think this is relevant to my question. I know 'how' to turn an epub into a kepub using calibre. My question was whether calibre's conversion from standard ebooks epub to kepub will give materially different results from getting the kepub direct from standard ebooks

I have tested with a few books and can't 'see' a difference but that's a very small sample size. I am planning to store the epubs in calibre (as epubs are most compatible). I just wanted to check that I won't end up with a worse result by doing so

I don't know how the epub or kepub was made by standard ebooks. I do think they do a superb job at cleaning up some books from project Gutenberg and producing books that look great on e-readers. So not really sure what the garbage reference is

Does this mean we should remove any ebooks added to our kobos that we have added since 8.0.1, and then re-add them once this fix is applied in 8.0.2?

Only if you use hyphenation.

The thing is, with the KePub from Standard eBooks you don't know how it was made. The plugins to make KePub within calibre did have some bugs. However there is also the program KePubify that could have been used. I cannot say. That's why it's best to get the ePub and convert to KePub with calibre. this way you know how it's made. The KePub code has been redone in calibre and is now natively supported.
