First Steps

In order to run ghc and cabal, you need to adjust your PATH variable.

To do so, you may want to run 'source /d/CLOUD/Programmier-Workshops/Kurse/Haskell/Programme/Haskell/ghcup/env' in your current terminal
session as well as your shell configuration (e.g. ~/.bashrc).

Start a simple repl via:
  ghci

Start a new haskell project in the current directory via:
  cabal init --interactive

Install other GHC versions and tools via:
  ghcup list
  ghcup install <tool> <version>

To install system libraries and update msys2/mingw64,
open the "Mingw haskell shell"
and the "Mingw package management docs"
desktop shortcuts.

Configuration

Cabal configuration file is by default located at

<$ENV:USERPROFILE>\AppData\Roaming\cabal\config

Create your first project

Create a haskell project

cabal init
cabal build
cabal run

Configure VS Code with Haskell Support

Install required components

$ cabal install hlint

Configure VSCode

$ stack new vscode-haskell-config
$ cd vscode-haskell-config
$ stack setup

Install an additional source code formatter

$ stack install brittany

Updating packages

To check if any new update is available you can use conda update. If any update is available you can choose whether to install or not to install it.

You can use an Anaconda prompt or the terminal for the following steps: 

• Update specific package: 

conda update package-name

conda update --all

• Update all packages in the current environment: 

conda update -n myenv --all

• 4. Update Python: 

conda update python

5. Update conda itself: 

conda update conda
