# This script downloads the 'ghcup' binary into '~/.ghcup/bin/' and then runs an interactive
# installation that lets you choose various options. Below is a list of environment variables
# that affect the installation procedure.

# Main settings:
#   * BOOTSTRAP_HASKELL_NONINTERACTIVE - any nonzero value for noninteractive installation
#   * BOOTSTRAP_HASKELL_NO_UPGRADE - any nonzero value to not trigger the upgrade
#   * BOOTSTRAP_HASKELL_MINIMAL - any nonzero value to only install ghcup
#   * GHCUP_USE_XDG_DIRS - any nonzero value to respect The XDG Base Directory Specification
#   * BOOTSTRAP_HASKELL_VERBOSE - any nonzero value for more verbose installation
#   * BOOTSTRAP_HASKELL_GHC_VERSION - the ghc version to install
#   * BOOTSTRAP_HASKELL_CABAL_VERSION - the cabal version to install
#   * BOOTSTRAP_HASKELL_INSTALL_STACK - whether to install latest stack
#   * BOOTSTRAP_HASKELL_INSTALL_HLS - whether to install latest hls
#   * BOOTSTRAP_HASKELL_ADJUST_BASHRC - whether to adjust PATH in bashrc (prepend)
#   * BOOTSTRAP_HASKELL_ADJUST_CABAL_CONFIG - whether to adjust mingw paths in cabal.config on windows
