Format problems in epub version of cookbook: Can not open in emacs nov.el
I can read the epub version of the cookbook in Okular, but not in emacs nov.el. I wondered about that so I installed the freely available tool epubcheck (available at least in Ubuntu), https://github.com/w3c/epubcheck. It found one fatal error, and 139 non fatal errors. FATAL(RSC-016): common-lisp-cookbook.epub/ch031.xhtml(407,10): Fatal Error while parsing file: The element type "br" must be terminated by the matching end-tag "".
Perhaps this project needs a set of (automatic) tests, at least sanity checks? One such test could be to build PDF and EPUB versions of the document and then run format checkers on them.
I believe I solved the problem: There are two empty fields in metadata.txt: "identifier" and "publisher". If I remove these fields, and then generate the epub, then emacs nov.el can display the document.
Another, unrelated, bug: In README.md, the line
Run gem install bundler -v 1.17.3 to install bundler.
should be
Run gem install bundler -v 2.1.4 to install bundler.
(The version listed at the end of Gemfile.lock)
Hi, thanks for the good pointers.
I fixed the missing metadata fields and reduced a little the number of non-fatal errors, but I was unable to try nov.el. Is this file good https://github.com/LispCookbook/cl-cookbook/releases/download/2022-08-30/common-lisp-cookbook.epub ?
Yes, this file seems to work fine in nov.el. I looked at perhaps ten different sections. Thanks for fixing this!
