show alternative package if it doesn't support Python 3

[chhantyal]

Just a thought before going ahead:
Would be nice to provide an alternative package if

1. Package is abandoned and has drop-in replacement
2. Package is not going to be supporting Python 3 because there already alternative package doing so.

etc.

Color would be yellow?

Or just add short notes below table to inform about existence of alternative.

+1 for this. For example it is not immediately obvious that sqlalchemy-migrate is a third-party effort and the preferred migration tool for sqlalchemy is the package named alembic.

Yeah it should still be green, but with a note that a drop-in replacement exists?

Point of fact, MySQLdb is basically dead, but there's now a fork (drop-in replacement, no API changes) recommended by Django in their docs:

MySQL DB API Drivers

• MySQLdb is a native driver that has been developed and supported for over a decade by Andy Dustman.
• mysqlclient is a fork of MySQLdb which notably supports Python 3 and can be used as a drop-in replacement for MySQLdb. At the time of this writing, this is the recommended choice for using MySQL with Django.

PyMySQL also seems to work nicely - pure-Python replacement that doesn't have a compile step on install. Nice for us fortunate enough to have to use Windows :)

+1 from me.

(I'd like to add that I've made a 2.7/3.4+ fork for Fabric: https://pypi.python.org/pypi/Fabric3)

[brettcannon]

I should mention that some of the overrides in caniusepython3 are actually drop-in alternatives so some of that data is already collected for you (e.g., look at how BeautifulSoup and PIL are overridden).

[mathiasertl]

@brettcannon in that case can you add Fabric3 as drop-in alternative to Fabric?

[brettcannon]

@mathiasertl Please file an issue or send a PR against brettcannon/caniusepython3

Another example is https://pypi.python.org/pypi/ipaddr which was forked and became a builtin library in Python 3: https://docs.python.org/3/library/ipaddress.html

[nicktimko]

The wheel of win shows more and more win, but it's perhaps a bit strange when the Python 3 alternatives "overrides" aren't signified in any way. Noting which have alternate packages via https://github.com/brettcannon/caniusepython3/blob/master/caniusepython3/overrides.json might be prudent so there isn't any confusion if someone tries to install a package name (e.g. mysql-python) that's green but it then fails under 3.

[nickjacobson]

2 more that are in white, and that have a version in Python 3:
"python-openid": "https://pypi.python.org/pypi/python3-openid" (already in overrides.json)
"python-ldap": "https://github.com/pyldap/pyldap" (I requested to have this added to overrides.json)

[ConorMcGee]

Sorry if I've misunderstood what's supposed to be happening here, but why is Fabric listed as green with no mention on the site that you have to use a fork?

[chhantyal]

@mcgeeco Sorry if it was misleading. I clarified the text here 1aad080 will be updated in next deployment

[ConorMcGee]

Ah that makes sense. Personally I like the yellow idea. Thanks!
