When trying ebook-convert with TXT output and --max-line-length option set to more than 25, e.g.
ebook-convert d_ch.fb2 text.txt --max-line-length 70
The command crashes with the following error:
.....
Converting XHTML to TXT...

TypeError: slice indices must be integers or None or have an __index__ method
This is most likely due to the fact that for some reason, in the function cleanup_text, the type of self.opts.max_line_length is float, which, when passed to line.rfind(...) on line 160, causes the error. This behavior of rfind can be reproduced by running something like
"aaaa aaaa".rfind(" ", 0, 1.0)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: slice indices must be integers or None or have an __index__ method
In a Python console.
Included is a patch that fixes this by forcibly converting self.opts.max_line_length to an int, although I am not sure whether it broke something else or not. |
