In their own words
frum
frum is a free Ruby version manager written in Rust. It can install and uninstall Ruby versions, list available or installed versions, and select a global or local version. It also works with .ruby-version files, so projects can specify which Ruby version frum should use. The project describes its implementation as pure Rust and says it does not use ruby-build. Installation methods listed include Homebrew or Linuxbrew, Arch Linux packages, Cargo, and release binaries. The README provides setup instructions for Bash, Zsh, and Fish and lists shell auto-completion. Ruby installation accepts configuration options such as an OpenSSL directory and jemalloc allocator selection. The README reports a benchmark in which evaluating frum init ran about six times faster than evaluating rbenv init. The project is MIT licensed and welcomes contributions, issues, and pull requests. Linux and macOS are listed as supported platforms; Windows is mentioned in the project’s goals. Its latest listed release is v0.1.2.
GHCup
GHCup is a free, open-source installer and version manager for the Haskell toolchain. It installs and manages GHC, cabal-install, Haskell Language Server (HLS), and Stack versions; Stack can also be configured to use GHC versions managed by GHCup. Listed functionality includes a terminal user interface and GHC cross-compilation. Installation guidance covers terminal commands for Linux, macOS, FreeBSD, and WSL2, alongside PowerShell instructions for Windows. The project describes Windows support as being in an early stage and uses a shim wrapper because Windows does not properly support symbolic links. On macOS, GHCup may prompt for command line tools; Windows setup includes msys2. The installer should be run as a non-root user on Unix-like systems and a non-admin user on Windows. GHCup relies on precompiled binaries, so compatibility can depend on the distribution and libraries such as libtinfo. WSL1 and macOS versions earlier than 10.13 are unsupported. Some ARM binaries are experimental: Stack and HLS on Linux ARM, and HLS bindists on macOS aarch64. Configuration can be stored in ~/.ghcup/config.yaml, with command-line options taking precedence.
