Getting Started

If you have the Rust toolchain installed, you can simply install moonup with Cargo:

cargo install moonup@0.1.0-rc.1

Or you may download the latest release from GitHub releases, manuallly extract the archive and put the executables in a directory that is in your PATH.

After installation, run moonup help to see the available commands.

$ moonup help
Moonup is a tool to manage multiple MoonBit installations.

  completions  Generate shell completions
  default      Set the default toolchain
  install      Install or update a MoonBit toolchain [aliases: i]
  pin          Pin the MoonBit toolchain to a specific version
  show         Show installed and currently active toolchains
  update       Update MoonBit latest toolchain and moonup [aliases: u]
  which        Show the actual binary that will be run for a given command
  help         Print this message or the help of the given subcommand(s)

Options:

How It Works

Moonup allows you to install multiple MoonBit toolchains and switch between them easily. All MoonBit toolchains (with the core standard library) are installed in Moonup's toolchains directory.

Moonup creates shim executables that replace the original MoonBit executables in the PATH. When you run a MoonBit command, the shim executable determines which MoonBit toolchain to use and proxies the command to the actual MoonBit executable in the desired toolchain.

With this approach, you can switch between MoonBit toolchains across projects easily without needing to change the PATH.

MoonBit Releases

Moonup downloads MoonBit releases from chawyehsu/moonbit-binaries, which is powered by GitHub Actions and archives MoonBit releases continuously from the official website.

cargo build
# run and test
cargo run -- help

0.1.0 Roadmap

  • An install command to install multiple MoonBit toolchains
  • A pin command to pin toolchain to a specific version in a project
  • Create shim executables to switch between toolchains automatically
  • A default command to set the default toolchain
  • A show command to show installed and currently active toolchains
  • A which command to show the actual binary that will be run for a given command
