Can you open a ticket about that with a test case, I'll try to fix it for the next release.

I would, but I am getting "DatabaseError: database disk image is malformed" at the moment.

A very minimal demo file is here:

Hmm sqlite database corruption. Should be fixed now. Please try again.

I feel like a complete idiot, but I simply can't figure out how does chapter-detection and toc-generation work. I am still using the HTML code described earlier:

Code:

<h2 id="chapter-10">The Attack</h2>
<p>Something attacked you. You are dead.</p>

I tried many different combinations of --chapter-regex, --chapter-attr, --add-chapters-to-toc, but no go - I never get a TOC. Unfortunately, the documentation is rather sparse on chapter detection. I took it to mean:

1) --add-chapters-to-toc is required if I want the TOC.

2) --chapter-regex=. should, as I understand it, match any h1-h6 tag whose content ("The Attack", in my case) is at least one character long.

3) --chapter-attr=h2,id,chapter should match any <h2 id="chapteranything">

But it does not. If I use all three or just 1 and 2 or 1 and 3, I always get the same result: no TOC items at all.

Is there an OPF file in the same directory as the html file?

tkirke · 08-28-2008, 02:07 PM

Hi,
I've used calibre's html2lrf to convert a html utf-8 file to LRF.
When I use calibre's viewer, the document renders correctly. However with Sony's viewer or on the Ereader itself I can't see some characters. For example
unicode 233 (é) is OK, but 257 (ā) is not.
I've tried embedding a font using html2lrf but haven't gotten this to work. Is this a conversion problem or an Ereader issue? How do I get around this?
Thanks

font embedding is a chancy thing. You have to try with various fonts until you hit a good combination.

No. Only the HTML file.

kovidgoyal · 08-28-2008, 03:48 PM

And was the exact commandline you used?

Well, I really don't get it: today it worked with the same command line:

Code:

html2lrf.exe --no-links-in-toc --chapter-attr=h2,id,. --force-page-break-before-tag=h2 --add-chapters-to-toc --lrs "demo.htm"

I still don't get it how to choose which tags should be considered headers (--chapter-regex is quite unclear ("The regular expression used to detect chapter titles. It is searched for in heading tags (h1-h6). Defaults to chapter|book|appendix" - what exactly is searched? Can I limit it to h2 only or will it always work on h[1-6]?) and --chapter-attr will only work with chapters which DO have an attribute (apparently it can't be used to detect "all <h2> no matter what attributes are used").

kovidgoyal · 08-29-2008, 10:19 AM

Yeah the chapter detection options are a bit of a mess (mainly for legacy reasons). In the next release of calibre, you'll be able to set the attribute value to none to match tags with no attributes.

i have an html file which is about 14 mb.. the program crash all the times when i try to open it with calibre.. the htlm file is all text.. it is the penal law for new

kovidgoyal · 09-29-2008, 02:19 AM

zip it up and then add it.

pepak · 09-29-2008, 01:48 PM

html2lrf is able to convert a <hr> tag to horizontal line across the whole display. Is there a way to get the same result using CSS only? "border: solid 1px black" didn't work when I tried it, but maybe there's another way of forcing html2lrf to produce a solid horizontal line?

(Actually, a box around a certain element would be even better, but I suspect LRF format doesn't support that.)
