Greetings! I've been using ePub3-itizer successfully, but ran across an error message with one book:
Code:
..converting: OEBPS/content.opf
..parsing: OEBPS/toc.ncx
Traceback (most recent call last):
File "/Applications/Sigil.app/Contents/plugin_launchers/python/launcher.py", line 135, in launch
self.exitcode = target_script.run(container)
File "/Users/J/Library/Application Support/sigil-ebook/sigil/plugins/ePub3-itizer/plugin.py", line 251, in run
doctitle, toclist, pagelist = parse_ncx(bk, temp_dir)
File "/Users/J/Library/Application Support/sigil-ebook/sigil/plugins/ePub3-itizer/plugin.py", line 564, in parse_ncx
toclist.append((lvl, navlabel, href))
UnboundLocalError: local variable 'navlabel' referenced before assignment
Error: local variable 'navlabel' referenced before assignment
Thank you for any help!
ETA: I created a new toc.ncx (using Sigil's "Generate Table of Contents"), after which the ePub3-itizer plug-in succeeded in converting to ePub3. But I'm still curious as to what went wrong since the epub2 validated.
