## About the book
4+
5+
To get more information about the source text "Parallel and Concurrent
6+
Programming in Haskell" by Simon Marlow, please visit the [book's web

## Installing stack
10+
11+
Stack is a tool for downloading, installing, and building haskell projects. It
12+
takes care of handling multiple compiler versions, and supports sandboxing
13+
sharing build results between projects.
14+
15+
### Windows 64bit
16+
17+
Download and run the installer from
18+
[here](https://www.stackage.org/stack/windows-x86_64-installer).
19+
20+
Also, take a look at the instructions
21+
[here](http://docs.haskellstack.org/en/stable/install_and_upgrade/#windows).
22+
While not strictly necessary, it is a good idea to use `set
23+
STACK_ROOT=c:\stack_root` with stack, due to windows MAX_PATH restrictions.
24+
25+
### Mac OS
26+
27+
```
28+
brew install haskell-stack
29+
```
30+
31+
### Linux 64bit
32+
33+
There are also distribution specific versions (see the "Other" section below),
34+
but I find this to be the most straightforward way to get a recent version:
35+
36+
```
37+
wget https://github.com/commercialhaskell/stack/releases/download/v1.0.4/stack-1.0.4-linux-x86_64.tar.gz
38+
mkdir -p ~/.local/bin
39+
tar -xvf stack-1.0.4-linux-x86_64.tar.gz
40+
mv stack-1.0.4-linux-x86_64/stack ~/.local/bin/stack
41+
42+
# Optionally, remove the archive and its unpacked dir
43+
rm -r stack-1.0.4-linux-x86_64
44+
rm stack-1.0.4-linux-x86_64.tar.gz
45+
```
46+
47+
Then, try `which stack`. If the response is not the `.local/bin/stack` folder
48+
within your home directory, then you will need to add `.local/bin/stack` to your
49+
PATH. To do this, add the following to your `~/.profile`, and then start a new
50+
terminal:
51+
52+
```
53+
if [ -d "$HOME/.local/bin" ] ; then
54+
PATH="$HOME/.local/bin:$PATH"
55+
fi
56+
```
57+
58+
### Other
59+
60+
See the installation instructions
61+
[here](http://docs.haskellstack.org/en/stable/install_and_upgrade/).
62+
63+
## Cloning this repo and setting up your environment
64+
65+
Clone this repo as follows:
66+
67+
```
68+
git clone https://github.com/seahug/parconc-examples.git
69+
```
70+
71+
We then ask stack to set up an appropriate version of GHC:
72+
73+
```
74+
cd pcph/
75+
stack setup
76+
```
77+
78+
## Loading examples into ghci
79+
80+
Usually we'll only want to load up a single example at a time. `stack ghci` is
81+
a good way to do this:
82+
83+
```
84+
mgsloan@computer:~/oss/seahug/pcph$ stack ghci --no-build :parmonad
85+
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
86+
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
87+
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

89+
The following GHC options are incompatible with GHCi and have not been passed to it: -threaded

126+
127+
## Building all examples
128+
129+
To build optimized versions of the examples, run `stack build`. Then, you can
130+
run the example by name by using `stack exec`. For example, `stack exec --
131+
parmonad 4 5`.
