I needed Java.

But does work on linux?

once installed, it gave me this error:

Error: Interpreter python3.4,python2.7 has no path set

any suggestions?

my machine has python 2.7 inside. i tried to install python 3.7 but nada

You have to go into Sigil's plugin preferences and tell it the python interpreter (must be 3.4+) to use. Auto should work, but you may have to Browse and select it manually.

Thank you very much

This is a neat addition, so a belated thank you! I only now read the discussion.

I'm a linux user, on a windows laptop there is something wrong when I try to run epubcheck. It seems to be the same error no matter which epub, so I'm guessing it's something with the installation.

Sigil 1.1.0, Qt 5.12.6, Windows 10.

I think python is included in (windows)-sigil? I just went and downloaded and installed latest Python, no change.

Ideas?

Did you follow the instructions and check whether Java is installed?

No I didn't... I guess I'm so used to my old Linux system that I presumed the Windows sigil-installer would let me know of any pre-requisits.

Thanks!

Why would Sigil be involved? Java is only a prerequisite of this third-party plugin. Sigil doesn't require Java for anything.

[patrik]

Yes, that's a rational true statement.

But as an irrational human being, it's easy to conflate everything sigil-ish.

I have just loaded this plugin to check an epub2 file because I haven't been able to get any response from http://validator.idpf.org/ - every attempt over the past few days has just timed out without any connection to the server. Is the online checker still in business?

The check with this plugin worked fine with 'No problems found'. Then I tried setting 'usage' to true and this produced a few errors (or suggestions) such as :

USAGE(HTM-021): Content file doesn’t contain lang attribute.
Col: 151: USAGE(ACC-013): Content file contains at least one inline style declaration.

Can you point me to a reference where I can find the key to stuff like ACC-013 and HTM-021 ?

[KevinH]

They appear to me to be quite well defined. The first means neither your html tag nor the body tag has an lang="en" (or whatever language the page is in). Unless multiple languages are used, this is not an error or even a warning as the epub metadata defines the lang for the book.

The second says you are using inline styles, in other words a style defined in a style attribute of a html tag. This is not an error or warning as it is completely legal but many epub developers do not like them and they prefer standalone stylesheets for all styles.

Neither of these matter in any way.

[philja]

Hi Kevin - I realised from the first post in this thread that the info revealed by setting 'usage' to true was advisory for those seeking perfection and not critical. I was hoping for a quick lead to the source documentation which listed all these 'events' like CSS-024.

This seems a little surprising to me as each chapter_n.xhtml contains on line 3 :

<html xml:lang="en-GB" xmlns="http://www.w3.org/1999/xhtml">

generated by export from LO Writer w. writer2epub a couple of years' ago. Should I replace "en-GB" with a plain "en"?

I am happy to learn that inline styles are inoffensive.

There's two possible items, lang and xml:lang. Epubcheck only seems to like one of them.

[KevinH]

The current epub spec looks for just the lang attribute not xml::lang and if both are present lang takes precedence.
