## プロジェクトの歴史と使われ方
GHCup is the Haskell toolchain installer used to install and switch versions of GHC and related tools such as Cabal, Haskell Language Server, and Stack.
### プロジェクトの歴史
The ghcup-hs repository describes GHCup as the main installer for the Haskell language. Hackage describes the Haskell implementation as a rewrite of an earlier shell-script ghcup, and the repository release history shows a 0.1.0-pre release in 2020 followed by Hackage publication in 2021.
### 採用の歴史
GHCup gained ecosystem significance because it solved a practical bootstrapping problem: Haskell users often need specific compiler and tool versions for each project. By living under haskell.org documentation and the haskell GitHub organization, it became a central installation path for the Haskell toolchain rather than a distro-specific add-on.
### 使われ方
Practitioners use ghcup to install, list, set, remove, and compile toolchain versions. Its guide and changelog show growth beyond basic installation into a TUI, metadata-driven installation, release channels, tool revisions, health checks, and support for editor workflows that depend on Haskell Language Server.
### パッケージ好きにとっての重要性
For package maintainers and compiler testers, GHCup matters because it turns compiler version juggling into a reproducible user-level operation. It also exposes metadata and separate companion repositories for metadata, web documentation, Docker images, and GitHub Actions setup.
### タイムライン
- 2020: ghcup-hs was created on GitHub and 0.1.0-pre was released.
- 2021: ghcup 0.1.14.1 was uploaded to Hackage.
- 2023: ghcup 0.1.20.0 added Windows TUI support and Stack metadata support.
- 2026: ghcup 0.2.1.0 introduced the installer DSL and revision support.
### Related projects
- The ghcup-hs README points to ghcup-metadata, ghcup-www, ghcup-docker, and ghcup-setup as companion projects.
