A simple(?) RTL conversion?

Colonel Cathcart · 10-25-2021, 01:42 PM

I setup the Libra to move to the previous/next page by pressing the screen on the left/right. What really happens depends on the text I read. When I read English books right press progress the book, left goes back. When I read a Hebrew book, since it's a RTL language the behavior is reversed: Pressing left moves forward, right goes back. It's like magic, works beautifully.

I just borrowed a book in Hebrew from the library and the magic is broken. It behaves like reading a book in English when it comes to pressing the screen. Using the physical buttons still works as expected.

It's probably something with the book, right? some "dir=rtl" missing from Html or CSS or something, right? Can someone point me in the right direction how to fix this?

Other than that, the book renders just fine on screen, text, justification, everything.

I'm trying to help myself here, comparing to another Hebrew book that works just fine.
Indeed, all .html files' html tag was missing the dir="rtl" attribute (is it an attribute? I'm not familiar with all that web development jargon). Adding that didn't do that trick.

Then I saw that .opf file is missing what I highlighted here:
<spine page-progression-direction="rtl" toc="ncx">
That did the trick!
