getgo checks https://golang.org/dl/?mode=json to determine the latest stable version of Go to download and verifies its checksum. The tool won't download the binary if a verified one already exists locally.
It is command line utility with an experimental GUI mode that is only half-baked.
Pre-built binaries are available in the releases section or it can be built if you already have Go installed:
go get lazyhacker.dev/getgo
If you've downloaded the source then the standard Go tool for building can be used:
go build main.go
Just run getgo to download the most recent stable archive for the platform it
is running from. To also extract the archive run it with the '-x' flag:
getgo -x <dir to extract to>
On Windows, getgo can be told to download the installer with
getgo -kind installer
To download to a specific directory:
getgo -dir ~/Downloads
To download another OS and/or arch version, use the '-os' and the '-arch' flags:
getgo -os windows -arch amd64
To get help info:
getgo -help
I use getgo make it easier for me to upgrade Go when a new release comes out. The steps are generally:
- Download Go from golang.org.
- Verify the download.
- Delete /usr/local/go.
- Untar the downloaded .tar.gz file to /usr/local
With getgo, this will do the above:
sudo rm /usr/local/go
sudo getgo -x /usr/local
I'm experimenting with building GUI apps with Go. Fyne is a cross-platform Go GUI toolkit that I started testing.
To try the Fyne version (require installing Fyne and its dependencies):
go get lazyhacker.dev/getgo
go run -tags gui lazyhacker.dev/getgo
