Installing stack

Stack is a tool for downloading, installing, and building haskell projects. It takes care of handling multiple compiler versions, and supports sandboxing sharing build results between projects.

Windows 64bit

Download and run the installer from here.

Also, take a look at the instructions here. While not strictly necessary, it is a good idea to use set STACK_ROOT=c:\stack_root with stack, due to windows MAX_PATH restrictions.

Mac OS

brew install haskell-stack

Linux 64bit

There are also distribution specific versions (see the "Other" section below), but I find this to be the most straightforward way to get a recent version:

wget https://github.com/commercialhaskell/stack/releases/download/v1.0.4/stack-1.0.4-linux-x86_64.tar.gz
mkdir -p ~/.local/bin
tar -xvf stack-1.0.4-linux-x86_64.tar.gz
mv stack-1.0.4-linux-x86_64/stack ~/.local/bin/stack

# Optionally, remove the archive and its unpacked dir
rm -r stack-1.0.4-linux-x86_64
rm stack-1.0.4-linux-x86_64.tar.gz

Then, try which stack. If the response is not the .local/bin/stack folder within your home directory, then you will need to add .local/bin/stack to your PATH. To do this, add the following to your ~/.profile, and then start a new terminal:

if [ -d "$HOME/.local/bin" ] ; then
    PATH="$HOME/.local/bin:$PATH"
fi

Other

See the installation instructions here.

Cloning this repo and setting up your environment

Clone this repo as follows:

git clone https://github.com/seahug/parconc-examples.git

We then ask stack to set up an appropriate version of GHC:

cd parconc-examples/
stack setup

Loading examples into ghci

Usually we'll only want to load up a single example at a time. stack ghci is a good way to do this:

mgsloan@computer:~/oss/seahug/pcph$ stack ghci --no-build :parmonad
There were multiple candidates for the Cabal entry "Lex" (/home/mgsloan/oss/seahug/pcph/examples/parinfer/Lex.x), picking /home/mgsloan/oss/seahug/pcph/examples/parinfer/Lex.hs
There were multiple candidates for the Cabal entry "Parse" (/home/mgsloan/oss/seahug/pcph/examples/parinfer/Parse.y), picking /home/mgsloan/oss/seahug/pcph/examples/parinfer/Parse.hs

Building all examples

To build optimized versions of the examples, run stack build. Then, you can run the example by name by using stack exec. For example, stack exec -- parmonad 4 5.
