The first part of the workshop will be using a web app, so you will only need a web browser to join in. Even if you're not a developer by day, you will get your hands dirty with some Haskell.
You can stop reading here.
The second part will be more developer-focussed and will require you to install some things.
ghc should be installed and in your $PATH
cabal should be installed and in your $PATH
- Bring your own favourite text editor :)
- My preference on Ubuntu is Kate.
- vscode and emacs are pretty good too.
Some Haskell libraries call out to native libraries. I believe the only one we'll need is zlib.
gitcurl
sudo apt install ghc cabal-install git curl zlib1g-devel
- Try https://www.haskell.org/platform/
- I haven't confirmed this on a Mac yet.
- Try https://www.haskell.org/platform/
- Otherwise if you're running Windows 10, you can install Ubuntu as an app and then the Ubuntu instructions above will work.
There is a sample starter project included in this repo to make sure your toolchain is all working.
Sync your packages:
~$ cabal update
Wrap the starter project in a sandbox (dependencies will be installed inside the project, rather than polluting ~/.ghc ~/.cabal)
~$ cd riksgransen-haskell/starter
~/riksgransen-haskell/starter$ cabal sandbox init
Download/build the dependencies: (I've deliberately included way more dependencies than necessary, in case we want to try different things out)
~/riksgransen-haskell/starter$ cabal install --dependencies-only
Build/run the starter project:
~/riksgransen-haskell/starter$ cabal run
You should now be able to curl/visit http://127.0.0.1:3000/ and see
Hello, world!
