Run more than one version of IHaskell?

[dabro]

Is it possible to build and run ihaskell on different GHC versions? eg 7.10.1 and 7.10.3? If you try doing so, each overwrites the other's ihaskell binary in .local/bin. It's easy to save a copy, but the location seems to be hardwired in?

The path is “hard-wired” only in ~/.local/share/jupyter/kernels/haskell/kernel.json. It should be possible to make multiple different IHaskell kernels by

$ cp -r ~/.local/share/jupyter/kernels/{haskell,haskell-7.10.1}

and editing that file accordingly in one version.

With the nix package manager you can also change ghc version without issues with overwrites.

It looks like we hardcode kernelName in src/IHaskell/IPython.hs which is the name of the folder that kernel.json is put under. It doesn't look like kernelName is used anywhere else so if anyone wants to make this configurable I would happily accept a pull request.
