Installation guide Windows (all users)

This guide assumes, that there is on user, that prepares the development environment for other user.

1. Download and install Haskell platform from https://www.haskell.org/platform/windows.html
2. * For stack, use a path accessible to all user (for example c:\stack). Installer adds to user variable PATH a path to executable stack.exe, and adds a new user variable STACK_ROOT. Move these values from user variables to system variables.
3. Download and install VS Code https://code.visualstudio.com/#alt-downloads. Use the system installer.
4. Open file c:\sr\config.yaml and add lines:

   system-ghc : true
   skip-msys : true
   

   These settings save time and space on disk (it will not install GHC while installing packages and MSYS2 for every user).

5. Open cmd and type:

   stack install intero phoityne-vscode haskell-dap

   • It will generate some executable files to default location: c:\Users\ -- YOUR NAME -- \AppData\Roaming\local\bin\ move them to the directory with stack.exe.
6. Open VS Code and install extensions:
   • Haskero
   • Haskell GHCi Debug Adapter Phoityne

Installation guide Ubuntu (single users)

1. Perform following commands:

   sudo apt-get install haskell-platform
   sudo apt-get install haskell-stack
   sudo snap install code --classic
   

   • Optional step - Right now (August, 2019) Haskell Platform from Ubuntu repositories contains GHC 8.4.4. Stack current default resolver is lts-14.00. It requires GHC version 8.6.5. It will automatically download this version. To save disk space, you can generate stack global config (for example stack path) and change the global resolver in file ~/.stack/global-project/stack.yaml to lts-12.15. Then open file ~/.stack/config.yaml and add lines:

   system-ghc : true
   skip-ghc-check: true
   

2. Continue with installation of required packages:

   stack install intero phoityne-vscode haskell-dap
   

3. Open VS Code and install extensions:
   • Haskero
   • Haskell GHCi Debug Adapter Phoityne
