epubReadingSystem object

schrijver · 12-07-2013, 09:34 AM

Hello
!

The epubReadingSystem object provides an interface through which a Scripted Content Document can query information about a User's Reading System.

It’s part of the ePub 3 standard: http://www.idpf.org/epub/30/spec/epu...bReadingSystem

An example implementation by Readium-js: https://github.com/readium/readium-j...ding_system.js

As far as I can tell from grepping the source code, the Calibre Viewer does not support the epubReadingSystem object? I attached a small ePub [1] that works for me in Readium, but not in Calibre [2].

Would you be interested in adding this feature to Calibre? I could see how far I can get with doing this, though I’ll need a little help.

This is what I imagine needs to happen:

1) Add a script to oeb’s existing array of Coffeescripts:
https://github.com/kovidgoyal/calibr...ks/oeb/display
2) Add the script to the loaders index:
https://github.com/kovidgoyal/calibr.../javascript.py
3 ) Specify that the script needs to be loaded? And only for EPUB3?

I was also wondering, how can I start the Calibre viewer with a JavaScript console.

Curious what y’all think of this,
Best,

Eric

You are welcome to add that object if you wish, your procedure for adding it is correct, simply send me a pull request. If you want access to a javascript console in the viewer simply right click on some text and choose Inspect Element, which will open the webkit inspector, that includes a js console.

In order to compile the coffescript into javascript, run

python setup.py coffee
