ghcup installs the Glasgow Haskell Compiler from the official
release channels, enabling you to easily switch between different
2020-04-22 14:14:10 +00:00
versions. It maintains a self-contained ~/.ghcup directory.
ENV variables:
* TMPDIR: where ghcup does the work (unpacking, building, ...)
* GHCUP_INSTALL_BASE_PREFIX: the base of ghcup (default: $HOME)
