@razzeee are you already working on this?

[razzeee]

No, just came to the conclusion seeing the other pr. Basically there should be everything in place, we just need to change the regex it's looking for.

Remember that some use print statements for unit tests

So, should we just grep for print statements in the code and report something like "hey, are you sure this print is intended"?

And by grep I actually mean something python-code-aware like the python's ast module

[razzeee]

Code aware would be awesome, but I'm not sure how it will handle third party deps like our kodi classes, which are nowhere to be found here :)
And yes, only prints would probably be the best. But then again, that would mean they don't show up in PRs and every reviewer must check the travis log and then check each of the files for false/positives.
Doesn't feel like we are on a good path here.

[Rechi]

We could classify using print statements only as warnings.
Additionally run 2to3 to check if print at least is in the new python3 syntax and only treat that case as fatal error if it isn't.

[mzfr]

so basically we want to search for print statement in all the addon files(.py) and if it's there then they should be reported right?

[razzeee]

Yes, as a warning. But we're not sure how useful a check like this will be in reality. So it might just turn out to be useless. But we need to try.

Technically, in Kodi ``print` is is implemented is implemented as xbmc.log(message, DEBUG): https://github.com/xbmc/xbmc/blob/master/xbmc/interfaces/python/AddonPythonInvoker.cpp#L19

So I'm not sure if we need to bother with print statements in addons.
