py2.6 support? about alfred-workflow HOT 6 CLOSED

I guess the Travis configuration is wrong. It is supposed to include 2.6.

It should be straightforward enough to ensure 2.6 support.

However, although AW doesn't absolutely depend on anything that wasn't in Python 2.6, it does depend on features that weren't present pre-10.8.

The main problem is #27. The security CLI program AW uses to store Keychain passwords doesn't work pre-10.8. It might be possible to work around this, but I don't have anything older than Yosemite to test it on. I'm fairly certain this is the only issue.

Is it worthwhile ensuring 2.6 support if AW isn't fully functional on 10.6/7?

I've run the test suite with 2.6, and these are the bits that don't work in 2.6 so far:

• background.py
  • new style formatting
• update.py
  • argparse not available
• test_web.py
  • assertIsNone not available
  • new style formatting
• test_workflow.py
  • assertIsNone not available
  • assertRaises not a context manager
• workflow.py
  • security -w not available on OS X < 10.8

Well, unless you have usage statistics, it's tricky question to answer.
If you look at stats from Omni Software, they have about 3% usage from OS X 10.7. So lets say Alfredapp have about the same distribution of users and 100000 active installations... So we are talking about 4k potential users. Out of these how many actually use custom workflows? Lets say 50% and out of these let's say 50% use AW workflows? So this affects about 1% percent? Is it important to you or not? :-) (obviously it's just a very rough guess which might be total BS, since usage of OS X 10.6 is actually higher than 10.7 in other reports I saw)

If making the changes to fix the issues above is not too hard, I would vote yes. The only real bummer is the argparse part. My workflow actually brings argparse with it to try and support 2.6.

I'm already going through the code. The changes are all pretty simple. The unit tests are by far the hardest part. argparse isn't a big deal, as the usage is totally trivial. It can easily be replaced with optparse or pure sys.argv.

As mentioned above, my main concern is that the Keychain access won't work pre-10.8, so some workflows will run on older installs and others won't.

At any rate, I've found a library that can parse the output of security find-generic-password -g …, so it should be possible to get that working on older versions of OS X, too.

Should all be fixed in 0551765.
