latestgo is a tool to automatically install the latest supported golang versions.
Installation is simple and no different to any Go tool. The only requirement is a working Go install.
go get go.tmthrgd.dev/latestgolatestgoThat's it. That's all there is to it.
latestgo will install the golang.org/dl wrappers for the latest patch
release for each supported version of go. This means you can run a specific go
version by running go1.X.Y. The go distribution will be installed into
$HOME/sdk/go1.X.Y.
As a convenience, latestgo writes the latest supported version of go to
$HOME/sdk/latest. This file can be used by shell scripts to find the latest
go binary. For example, in my .bash_profile I add
$HOME/sdk/$(cat ~/sdk/latest)/bin to $PATH so go will always be the
latest version of go installed.
latestgo also provides a single flag -all that will download all versions
of go since go1.8, including all patch releases, instead of only the latest
supported versions (the highest patch release of the last two major versions).
latestgo uses the JSON feed at https://golang.org/dl/?mode=json to retrieve the latest supported versions.
