[IPython-dev] Upgrading Kernels for IPython 3

[Matthias Bussonnier]

Hi Andrew,

I'm on my phone so I'll stay short.

Your kernel should work with IPython 3, we (should) detect and adapt older kernels.

The custom js/css is not ready yet. Some other things are still in motion.

Date is not fixed. The sooner the better. I, start to doubt there will be a release in the fall (maybe a beta). 

Kernels install at min a Json spec in .ipython/kernels/kernel name/kernel.json

--profile-dir and notebook-dir should still work. 

I'll give you some links later.

Cheers,

While I like this and would like to support this usage, historically I have shipped an "IHaskell" command which just ran IHaskell directly via "ipython --profile haskell" (along with doing a whole suite of other things). I would like to continue to provide this sort of mechanism to start IHaskell specifically, but it looks like "--profile" is deprecated (although it still appears in "--help"). What should I do? (Also, is "--profile-dir" also deprecated? It also appears in help and doesn't say it's deprecated.)
