Go

The following are instructions for using the go mise core plugin. This is used when there isn't a git plugin installed named "go".

If you want to use asdf-golang then use mise plugins install go GIT_URL.

The code for this is inside the mise repository at ./src/plugins/core/go.rs.

Usage

The following installs the latest version of go-1.21.x (if some version of 1.21.x is not already installed) and makes it the global default:

mise use -g [email protected]

Minor go versions 1.20 and below require specifying prefix before the version number because the first version of each series was released without a .0 suffix, making 1.20 an exact version match:

mise use -g go@prefix:1.20

Configuration

Set these with mise settings set [VARIABLE] [VALUE] or by setting the environment variable.

go_default_packages_file

• Type: string
• Env: MISE_GO_DEFAULT_PACKAGES_FILE
• Default: ~/.default-go-packages

Packages list to install with go install after installing a Go version.

go_download_mirror

• Type: string
• Env: MISE_GO_DOWNLOAD_MIRROR
• Default: https://dl.google.com/go

URL to download go sdk tarballs from.

go_repo

• Type: string
• Env: MISE_GO_REPO
• Default: https://github.com/golang/go

Used to get latest go version from GitHub releases.

go_set_gobin

• Type: bool | null
• Env: MISE_GO_SET_GOBIN
• Default: null

Sets GOBIN to ~/.local/share/mise/go/installs/[VERSION]/bin. This causes CLIs installed via go install to have shims created for it which will have env vars from mise such as GOROOT set.

If not using shims or not using go install with tools that require GOROOT, it can probably be safely disabled. See the go backend for the preferred method to install Go CLIs.

go_set_gopath deprecated

• Type: bool
• Env: MISE_GO_SET_GOPATH
• Default: false

Sets GOPATH to ~/.local/share/mise/go/installs/[VERSION]/packages. This retains behavior from asdf and older mise/rtx versions. There is no known reason for this to be enabled but it is available (for now) just in case anyone relies on it.

go_skip_checksum

• Type: bool
• Env: MISE_GO_SKIP_CHECKSUM
• Default: false

Skips checksum verification of downloaded go tarballs.

Default packages

mise can automatically install a default set of packages right after installing a new go version. To enable this feature, provide a $HOME/.default-go-packages file that lists one packages per line, for example:

github.com/Dreamacro/clash # allows comments
github.com/jesseduffield/lazygit

.go-version file support

mise uses a .tool-versions or .mise.toml file for auto-switching between software versions. However it can also read go-specific version files named .go-version.
