Triwanto,

IHaskell depends on the 'uuid' package and requires version 1.2.*. Check to make sure you have uuid installed. I build it with 1.2.13, and it looks like the most recent one is 1.2.14, which should also have that module [1]. So, before building, make sure you have uuid==1.2.* installed - I'm sort of new to cabal packaging, so perhaps my dependencies are not specified quite correctly, but that is the issue that message seems to point to.

Let me know how it goes. The full list of dependencies from the *.cabal file is as follows, in case you have other problems: build-depends: base ==4.6.*, zeromq3-haskell ==0.5.*, aeson ==0.6.*, MissingH ==1.2.*, basic-prelude ==0.3.*, classy-prelude ==0.6.*, bytestring ==0.10.*, uuid ==1.2.*, containers ==0.5.*, haskell-src-exts ==1.14.*, ghc ==7.6.*, ghc-paths ==0.1.*, random ==1.0.*, strict ==0.3.*, shelly ==1.3.*, text ==0.11.*

Note that zeromq3-haskell will require zmq3 installed, and in saucy that is provided via 'apt-get install libzmq3-dev', I think.

The .V4 module only seems to have appeared in version 1.2.6; as such you'll need to change the appropriate line to "uuid >= 1.2.6 && < 1.3" (assuming you have indeed tested and found that your code won't work with the 1.3.x versions).

Andrew,

I tried to install IHaskell on Ubuntu 13.10 (Saucy 64 bit) and recieved the following error

Resolving dependencies... Configuring IHaskell-0.1.0.0... Building IHaskell-0.1.0.0... Preprocessing executable 'IHaskell' for IHaskell-0.1.0.0...

IHaskell/Message/UUID.hs:10:8: Could not find module `Data.UUID.V4' Perhaps you meant Data.UUID.V1 (from uuid-1.2.3) Data.UUID.V3 (from uuid-1.2.3) Data.UUID.V5 (from uuid-1.2.3) Use -v to see a list of the files searched for. Failed to install IHaskell-0.1.0.0 cabal: Error: some packages failed to install: IHaskell-0.1.0.0 failed during the building phase. The exception was: ExitFailure 1

Any idea how to solve it?

Thanks,

Triwanto

Hey everyone!

I'm excited to announce the initial release of IHaskell, a Haskell language kernel for IPython:

http://gibiansky.github.io/IHaskell

IHaskell allows IPython to communicate with the kernel and evaluate Haskell code. This enables using IPython interfaces such as console, qtconsole, and most importantly, IPython notebook with Haskell. The IPython Notebook supports image, HTML, and LaTeX output, which enables things such as Javascript viewers for complex data structures or embedded graphs and makes it a great platform for interactive computing.

You can take a look at the code and install instructions here:

https://github.com/gibiansky/IHaskell

A general overview of the architecture is available as well:

http://andrew.gibiansky.com/blog/ipython/ipython-kernels/

Contributing: IHaskell is a very young project, but one that I think would make a great contribution to the Haskell community. There's still tons and tons left to do before it's on par with what IPython notebook is capable of, so if you're at all interested in contributing, please get in touch! I've tried to keep everything well-documented and readable, but I will also be happy to answer questions about the code myself.

If you find any bugs or edge cases or installation difficulties, please send me an email or create a Github issue for it!

Thanks, -- Andrew Gibiansky
