history

Project history and usage

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.

Project history

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.

Adoption history

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.

How it is used

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.

Why package nerds care

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.

Timeline

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.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
