Initial commit of getgo, a "one-line installer". Example use from bash: curl -LO https://get.golang.org/$(uname)/go_installer && chmod +x go_installer && ./go_installer && rm go_installer It's comprised of two parts: cmd/getgo/server: an App Engine application that redirects users to an appropriate installer based on the request path, which identifies the user's operating system. It's deployed to get.golang.org. cmd/getgo: a cross-compiled binary that does the heavy lifting of downloading and installing the latest Go version (including setting up the environment) to the user's system. The installers are served from the golang GCS bucket. Currently supported systems: linux, darwin, windows / amd64, 386 Authored by Jess Frazelle, Steve Francia, Chris Broadfoot.

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
Welcome to the Go installer!
Downloading Go version go1.8.3 to /usr/local/go
This may take a bit of time...
Adding "export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin" to /root/.bashrc

Setting up GOPATH
Adding "export GOPATH=/root/go" to /root/.bashrc
Adding "export PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin:/root/go/bin" to /root/.bashrc
GOPATH has been setup!
root@78425260fad0:~# which go
/usr/local/go/bin/go
root@78425260fad0:~# echo $GOPATH
/root/go
root@78425260fad0:~# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/local/go/bin:/root/go/bin
