DESCRIPTION
ghcup is the universal installer and version manager for the Haskell toolchain. It provides a centralized way to install, manage, and switch between multiple versions of GHC, Cabal, Stack, and HLS (Haskell Language Server).The tool handles downloading, installing, and setting up PATH entries for all Haskell development tools. It supports installing specific versions, setting global defaults, and maintaining multiple versions side-by-side. The interactive TUI mode provides a visual interface for managing installations.
