goup

goup is an elegant Go version manager write in rust.

goup is an attempt to fulfill the above features and is heavily inspired by Rustup, golang/dl, goup, goenv, gvm and getgo.

NOTE: Please keep in mind that goup-rs is still under active development and therefore full backward compatibility is not guaranteed before reaching v1.0.0.

Features

• Minimum dependencies, only depend on git. we may remove this dependency in future.
• Multi-platform compatible (Linux, macOS & Windows).
• Install/Remove Go versions with goup install/remove [TOOLCHAIN].
• Support Installing Go from source with goup install <nightly|tip|gotip>.
• List locally installed versions.
• Switch between multiple installed versions.
• Search available version of Go.
• Manage locally cache files(such as *.tar.gz, *.tar.gz.sha256).
• Upgrade goup itself.
• Friendly prompt.
• Should be pretty fast.

• semver
  • exact(=): allow updating to the latest version that exactly the version, so =1.21.4 means exactly match the version 1.21.4.
  • greater(>): allow updating to the latest version that less than or equal the version, so >1.21.4 means greater than 1.21.4.
  • greater equal(>=): allow updating to the latest version that less than or equal the version, so <1.21.4 means greater than or equal to 1.21.4.
