I am running this on Mint 18. This is the third script I have

I think your problem is that you're telling subprocess to run a
command called:
ebook-viewer
/home/jfb/Documents/eBooks/Javascript/GOOGLE_SHEETS/googlespreadsheetprogramming.epub
with no arguments. What you want is a command called:
ebook-viewer
and a single argument:
/home/jfb/Documents/eBooks/Javascript/GOOGLE_SHEETS/googlespreadsheetprogramming.epub
I think (but haven't tried it) that the simplest way to fix that is
to change the entry in self.programs from:
self.programs = ['jedit', 'google-chrome', 'doublecmd',
'ebook-viewer
/home/jfb/Documents/eBooks/Javascript/GOOGLE_SHEETS/googlespreadsheetprogramming.epub']
to:
path_to_file =
'/home/jfb/Documents/eBooks/Javascript/GOOGLE_SHEETS/googlespreadsheetprogramming.epub'
self.programs = ['jedit',
'google-chrome', 'doublecmd', ['ebook-viewer', path_to_file], ]
I made the changes you suggested.
def __init__(self):
path_to_book =
'/home/jfb/Documents/eBooks/Javascript/GOOGLE_SHEETS/googlespreadsheetprogramming.epub'
self.programs = ['jedit', 'google-chrome', 'doublecmd',
['ebook-viewer', path_to_book ]]
self.classname = {'jedit' : 'sun-awt-X11-XFramePeer',
'google-chrome':'google-chrome',
'doublecmd':'doublecmd',
'calibre-ebook-viewer': 'libprs500'}
self.open_and_move()
I noticed you have a , between the last two ]],s. I don't think you
meant that but I tried it both ways just incase.
and see if that fixes it. (It may not be enough, or the right
approach, but at least you'll get a different error if it is wrong
:-)
Unfortunately you are correct, I did get a different error message.

Regards, Jim
Replying to myself to report that I got it working.
I changed open_it to:
def open_it(self):
if self.program == 'ebook-viewer':
subprocess.call([self.program, self.path_to_book])
else:
subprocess.call([self.program])
After looking at it, I realized I should be providing the path when I
was actually opening the file in open_it not further down in
open_and_move where I was positioning the windows. Also I realize
open_and_move is a poor name and needs to be changed to move_it or
something.
I still get the following error but it does not seem to effect the
programs operation. So for now I am just glad it is working.
