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:

1. 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)
2. 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.
3. If there is a new version available, download it to temporary directory.
4. Backup existing Go installtion to temp.
5. Extract new Go archive to $GOROOT.
6. In case of an error, reverse backup to $GOROOT.
