No pop-up with reference mode

[net-buoy]

with calibre 0.9.43, OSX 10.8.4 if I open a book with calibre's reader and turn on Reference Mode I don't get a reference pop-up. What am I missing?

Works for me, is it a particular book or all books that it isn;t working for?

[net-buoy]

looks like some do work, and some don't.......

Reference mode only works if the book has actual paragraphs in it. If no paragraphs can be found, then it wont work. Some badly made books fake the look of paragraphs using other methods, which can break reference mode.

Impossible to say more without access to one of these books.

aha!

I opened the offending book in Sigil and yes indeed, the book uses

<div class="tx">
paragraph text
</div>

instead of a

<p>
text
</p>

and depending on section of the book there are several different classes for the paragraphs..... (which vary the leading bewteen 0 and 1 em)

is there a special tweak to address this, or is it just too variable to address?

Reference mode only works with <p> tags, it doesn't care about classes. This is because <div> tags can be nested, so there is no good way of getting a single useful number out of them, the same visual position in the book could correspond to several different nested <div>s. And you would get weird jumps in numbering, for example, if the visually first para is numbered 1, the visually second one may or may not be numbered 2 depedning on the presence of nested divs.

Use Sigil REGEX to replace those

with
<p class=\1</p>

just check the your stylesheet does not have an entry for

p { or div.<any of the classes used>
a simple
.<any of the classes used> is ok
