epub's Issues

html entities decoded incorrectly

For example,
“Captain Yerin,”
is rendered as
“Captain Yerin,”
instead of as
“Captain Yerin,”

(Yes, the entities are further escaped in this issue because github keeps parsing it all into smart quotes.)

-d fails on unicode when output redirected

Epub files containing unicode work beautifully when epub.py is called without command-line options. They also works perfectly well (at least in unicode locales) when the output is simply dumped to the screen. However, in most cases when dumping the contents of an entire ebook one would probably want to redirect the output, e.g., to a screen reader like less or to a file. The -d option fails in both these cases with the dreaded Python2 ascii codec error:

UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-9: ordinal not in range(128)

As explained here, this is because python2 treats printing to the terminal differently than redirecting output.

Solution
I was able to fix this problem by using kitchen.text.converters.getwriter() as suggested in the document above. Normal functioning of the program does not seem to have been affected, and unicode files now work as expected in all cases (including -d).

BeautifulSoup 4

can this be made compatible with BeautilfulSoup 4, thanks

Title finding for TOC does not always work correctly

Sometimes, when using epub.py to open some .epub files, the TOC view won't display the chapter titles just numbers.

Does anybody have a file it works with?

I'm still working on isolating the cause of this.

Bookmark support

Please implement a simple bookmark system, it would be great to keep tracking of the progress of readings.

Leading newline in titles

I don't know whether this will prove to be a common issue, but the first (and so far only) epub book I tried to open with this script displayed the table of contents all wrong and strangely truncated. It turned out to be that somehow there were leading newline characters in each "title" string.

The fix for me was to change current line #173 from:
screen.addstr(i, 0, '{0:-5} {1}'.format(start, title))
To:
screen.addstr(i, 0, '{0:-5} {1}'.format(start, title.strip()))

Enable scrolling between chapters

In other readers (I use FBReader and CoolReader), upon reaching the end of a chapter in an ebook, if I continuue scrolling down, I will immediately see the beginning of the next chapter. Similarly, if I scroll up from the beginning of a chapter, I will find myself at the end of the previous chapter. It's awkward to have to switch to the table of contents, select the next chapter, and switch back.

Long book title lines wrapping to next line in TOC page

When a book's title length exceeds the window width it wraps to the first line of the chapter listings. This is probably the case also for chapter listings themselves. I noticed this in a case where the first chapter "title" was blank, so there was nothing to over-write the word-wrap of the prior line's title. What then happens is that the next line will partially over-write the wrapped line, so the result will be the correct current line followed by the remainder of the previous line's wrap.

If you want, I can attach the offending epub example file.

Support mobi

Please support (non-DRM) mobi as well. There should be code in Calibre you can use.

epub assumes the source ebook is unicode

This is an incorrect assumption, and Project Gutenberg books (e.g. White Fang) seem to have decode errors.

We should use chardet for this.

Images don't show

I've tried many things and I have everything required installed but images do not show. Instead, their path is printed.

-d option fails

It tries to access a non-existent screen variable.

epub.py has syntax error

Installed epub.py from the .zip download. Attempt to run it produced this result

I know nothing about python, could you kindly advise me of the problem here.
I have installed python2-beautifulsoup3-3.2.1-3 and python3.4.2 on arch linux mainline 3.18.1

License not explicitly declared

It would be nice for a license to be declared to help with the truck factor, such as if you give up on this but others wanna maintain it.

A very easy-to-use site for this is:

Perhaps we should pull in dependencies for ebook handling?

There are numerous libraries that can do ebook processing, perhaps we would be better off simply using those?
