# 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_CABAL_XDG - don't disable the XDG logic (this doesn't force XDG though, because cabal is confusing)
|
|
# * BOOTSTRAP_HASKELL_INSTALL_NO_STACK - disable installation of stack
|
|
# * BOOTSTRAP_HASKELL_INSTALL_NO_STACK_HOOK - disable installation stack ghcup hook
|
|
# * 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
|
|
# * BOOTSTRAP_HASKELL_DOWNLOADER - which downloader to use (default: curl)
|
|
# * GHCUP_BASE_URL - the base url for ghcup binary download (use this to overwrite https://downloads.haskell.org/~ghcup with a mirror)
|
|
# * GHCUP_MSYS2_ENV - the msys2 environment to use on windows, see https://www.msys2.org/docs/environments/ (defauts to MINGW64, MINGW32 or CLANGARM64, depending on the architecture)
