Theme TOC. Remember theme for each ebook

erbilac · 07-13-2016, 06:32 AM

TL;DR/

could e-reader themes also theme the TOC? is it possible to assign a hotkey to swich themes or make Calibre automatically apply the last theme used on each ebook?

/TL;DR
--------------------------------------

I have just started playing with Calibre, I love it, but I cannot find the way to theme the TOC in the e-book reader.

My aim is to have an all black UI with light text over black background for all ebooks.

So I would like to create two themes, one entirely white (the unmodified one is OK) and one entirely black (including TOC, hidden or black TOC scrollbar, and other UI elements like toolbars if possible). Then, make the dark theme default, and when opening an ebook with special css (e.g. code with light background), switch to light theme and use external applications to invert colors.

Ideally, calibre should also automatically apply last theme used on each ebook and assign a hotkey to switch between themes.

I know that I could edit the stylesheet.css for each ebook, but, although I am not an expert, it seems that this is not an easy task because each ebook uses different names for code backgrounds and editing each ebook this way a tedious hit/miss job... Also, for the same reason, a user css style will not suit all ebooks... I might be wrong.
I would like to know what do you think is the best approach to what I want to do. Thanks

You can't style an EPUB2 TOC (NCX)

You could modify the template (see the FAQ on overrides at calibre-ebook.com) for the Inline TOC. That will not change any existing inline TOC automatically

Thanks for your reply.
The template file inline_toc_styles.css seems to serve another purpose. I edited it in many different ways but it does not affect the look of the ebook viewer TOC. Maybe I am doing it wrong... not sure.

I checked the source code of calibre but I am finding it hard to locate the file I need to modify so that the default TOC is white on black. Any help appreciated

The Viewers TOC is not an 'inline' TOC, that would be just another page of the book.

The TOC button in the viewer uses the NCX.
Kovid told you how to change the way the VIEWER displays the NCX (for all books)
