getgo

A proof-of-concept command-line installer for Go.

This installer is designed to both install Go as well as do the initial configuration of setting up the right environment variables and paths.

It will install the Go distribution (tools & stdlib) to "/.go" inside your home directory by default.

It will setup "$HOME/go" as your GOPATH. This is where third party libraries and apps will be installed as well as where you will write your Go code.

If Go is already installed via this installer it will upgrade it to the latest version of Go.

Currently the installer supports Windows, *nix and macOS on x86 & x64. It supports Bash and Zsh on all of these platforms as well as powershell & cmd.exe on Windows.

Usage

Windows Powershell/cmd.exe:

(New-Object System.Net.WebClient).DownloadFile('https://get.golang.org/installer.exe', 'installer.exe'); Start-Process -Wait -NonewWindow installer.exe; Remove-Item installer.exe

Shell (Linux/macOS/Windows):

curl -LO https://get.golang.org/$(uname)/go_installer && chmod +x go_installer && ./go_installer && rm go_installer

To Do

Check if Go is already installed (via a different method) and update it in place or at least notify the user
Lots of testing. It's only had limited testing so far.
Add support for additional shells.

Development instructions

Testing

There are integration tests in main_test.go. Please add more tests there.

On unix/linux with the Dockerfile

The Dockerfile automatically builds the binary, moves it to /usr/local/bin/getgo and then unsets $GOPATH and removes all $GOPATH from $PATH.

$ docker build --rm --force-rm -t getgo .
...
$ docker run --rm -it getgo bash
root@78425260fad0:~# getgo -v
