You can now try IHaskell directly in your browser at try.jupyter.org.
Alternatively, watch a talk and demo showing off IHaskell features.
IHaskell is a kernel for the Jupyter project, which allows you to use Haskell inside Jupyter frontends (including the console and notebook). It currently supports GHC 8.
Interactive In-Browser Notebook
Note: IHaskell does not support Windows. To use on Windows, install Virtualbox, install Ubuntu or another Linux distribution, and proceed with the install instructions.
Some prerequisites; adapt to your distribution.
sudo apt-get install -y python3-pip git libtinfo-dev libzmq3-dev libcairo2-dev libpango1.0-dev libmagic-dev libblas-dev liblapack-dev
pip3 install -r requirements.txt curl -sSL https://get.haskellstack.org/ | sh git clone https://github.com/gibiansky/IHaskell cd IHaskell stack install gtk2hs-buildtools stack install --fast ihaskell install --stack
You need to have Homebrew installed.
If you do not have it yet run
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" in your terminal.
You also need the Xcode command line tools.
You can install them by running
xcode-select --install in the terminal and following the prompts.
brew install python3 zeromq libmagic cairo pkg-config haskell-stack pango git clone https://github.com/gibiansky/IHaskell cd IHaskell stack install gtk2hs-buildtools stack install --fast ihaskell install --stack
Tested on macOS Sierra (10.12.6)
stack exec jupyter -- notebook
If you have the
nix package manager installed, you can create an IHaskell
notebook environment with one command. For example:
$ nix-build release.nix --arg packages "haskellPackages: [ haskellPackages.lens ]" <result path> $ <result path>/bin/ihaskell-notebook
It might take a while the first time, but subsequent builds will be much faster.
Where are my packages?
Stack manages separate environments for every package. By default your notebooks
will only have access to a few packages that happen to be required for
ihaskell. To make packages available add them to the stack.yaml in the ihaskell
directory and run
stack solver && stack install.
Packages should be added to the
packages: section and can take the following
(reproduced here from the stack documentation). If
you've already installed a package by
stack install you can simply list its
name even if it's local.
