goup

Tool that helps you to retrieve latest Go update from Google

Overview

Goup is a little utility that helps you to check and upgrade your local non-container Go version. It bascially does the following step-by-step:

Run go version to determine local Go version and go env for $GOPATH. The location of go is determined by supplied -p param, $PATH variable or default installation location (/usr/local/go or C:\Go)
Check https://go.googlesource.com/go/+refs to see if there is a version (tags starts with go), compare it against local version retrieved in (1). Can include beta, RC and latest major/minor version for comparison with -b, -rc and -u.
If there is a new version available, download it to temporary directory.
Backup existing Go installtion to temp.
Extract new Go archive to $GOROOT.
In case of an error, reverse backup to $GOROOT.

go get -u github.com/mkishere/goup
go build cmd/goup.go
