ePub to HTMLZ

MCBastos · 01-22-2021, 07:23 PM

I recently started getting errors when I attempt to convert an ePub to HTMLZ format. It seems to be a fairly recent regression; I have a copy of my epub collection in an external drive (under Portable Calibre, which was updated just before Christmas), and it works fine there.

Right. OK, let's see:
1. The file. Actually, it has happening to *any* ePub I try, but for the sake of argument, I'll use as example a file I downloaded from Standard Ebooks -- that would be the first Sherlock Holmes novel, "A Study in Scarlet" (compatible ePub version), which can be downloaded free from here:
https://standardebooks.org/ebooks/ar...udy-in-scarlet

2. The log:

Spoiler:

3. The output file: none

4. Conversion aborts with a big red error saying "Failed: Convert Book 1 of 1 (A Study in Scarlet)" -- details below (seems to me to be a copy of the log, but I'm posting it anyway)

Spoiler:

5. AFAIK, I didn't change any option for the conversion to HTMLZ. I even went to the "HTMLZ Output" dialogue and clicked on "Restore defaults." I also disabled every user-installed plugin that allowed disabling. Still got the error.

Look at your log, right at the top is the option you have changed from defaults

htmlz_class_style: 'inline'

change that back to default and you will be fine. As for the bug with that option it will be fixed in the next release. And read: https://manual.calibre-ebook.com/con...for-conversion to understand hw to reset conversion options to defaults.

MCBastos · 01-27-2021, 01:47 PM

Right, thank you, it is now working correctly.

I now understand what I did wrong in my attempt to reset to defaults here -- the button in the conversion dialog resets to default as set by the user in the Preferences dialog, not to default-as-it-was-originally-on-first-install. My mistake, thanks for your help.

Well, apparently my cluelessness helped to reveal a bug, so it was not a total loss.

I have a number of markdown documents, the codes are quite stadardized. All seems to work fine. But I have a few questions

All the footnotes are as follows:

Code:

Here's a simple footnote,[^note] and here's a longer one.[^anote]

[^note]: This is the first footnote.

[^anote]: Here's one with multiple paragraphs and code.

All these notes are converted to a list (1, 2, 3.) but

1) They are appended to the last html file. Can can it be a separate file?
I used this to break the files which work with h2. //*[name()='h2' or div[@class="footnote"]].

2) I inserted ".footnote ol {padding: 0;}" to the "Look and Feel" before converting, but this has no effect.

PS: I do all this on the Content Server.

No I dont think the markdown input processor has any way to insert page breaks before outputting footnotes. You can probably do it yourself by using extra css, something like footnote-selector::first-of-type {page-break-before: always}

What's .footnote??

Sorry, I hijacked this thread by mistake, created another thread, please delete for me

The .footnote is an interesting one.

Before I converted to epub, i just tap READ and Browser Viewer let me read it (by converting it on the fly). I prepared simple css to the Styles and .footnote works. That's why I copied the css for conversion. It has no TOC though, I had to convert to epub.

Since this document is in md and is updated regularly, I think I need a way to avoid dealing with the epub directly.

And the .footnote a { display: none;} is actually effective (the back-link is indeed hidden)
