list index out of range about python-irsend

[ChristopherRogers1991]

Both of those functions run the relevant irsend commands, and save the result in a variable called output. Can you try printing the value of output and pasting the result here?

Hey @ChristopherRogers1991 glad you answered :) the output variable for list_remotes contains the following string:

devinput
fernbedienung
devinput

playing around with it a little more gives the following results:

>>> print output
devinput
fernbedienung
devinput


>>> remotes = [l.split()[-1] for l in output.splitlines()]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: list index out of range
>>> output.splitlines()
['devinput', 'fernbedienung', 'devinput', '']
>>> 'devinput'.split()
['devinput']
>>> 'devinput'.split()[-1]
'devinput'

for list_codes the output is the following: (i am printing output here too)

>>> irsend.list_codes("fernbedienung")
00000000e0e006f9 KEY_UP
00000000e0e046b9 KEY_RIGHT

It looks like both of those have an empty line at the end, which is causing it to choke:

>>> ''.split()[-1]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IndexError: list index out of range

The solution is probably to eliminate the blank lines. It shouldn't be too hard to filter them out. I'll push up a change to a branch.

Out of curiosity, do you have any guesses about what's causing the blank lines? I've used this on a couple different versions of Raspbian, and a couple different versions of Ubuntu, and have not seen this happen.

Alright, I think https://github.com/ChristopherRogers1991/python-irsend/tree/bugfix/index_out_of_range should fix it. @jschiefner, can you test that branch, and let me know if it resolves the issue for you?

[ChristopherRogers1991]

#2 has been merged, which resolves this issue. It has been released in 1.0.1, and can be installed with pip.
