OO - Go Version Manager

Latest version: 0.1.0

oo was heavily inspired by tj/n.

Requirements

Supported system:

  • Mac OSX
  • Linux

Requirements:

  • Bash
  • Curl

Install

  1. Clone this repo.

    git clone https://github.com/hit9/oo.git $HOME/.oo
    
  2. Add this to your bashrc or zshrc:

    source $HOME/.oo/env
    

    Or this if you are using fish shell:

    source $HOME/.oo/env.fish
    

Note that you still need to set GOPATH manually in your bashrc or zshrc, oo doesn't take care of that:

export GOPATH=/path/to/your/gopath
export PATH=$PATH:$GOPATH/bin

Examples

Get go1.12.6 installed:

$ oo get 1.12.6

Then, the go1.12.6 is ready:

$ go version
go version go1.12.6 darwin/amd64

Use go1.12.6 as current go (or just oo 1.12.6):

$ oo use 1.12.6
=> go1.12.6

Run go from 1.12.6 temporary:

$ oo as 1.12.6 version
go version go1.12.6 darwin/amd64
$ oo as 1.12.6 run helloworld.go
Hello world!

List all installed go versions

$ oo ls
   1.12.5
=> 1.12.6

Build (or rebuild) go by version:

$ oo build 1.12.6
build go1.12.6..
build successfully

Get current go binary path:

$ oo bin
/Users/hit9/github/oo/go/bin/go

Remove a version:

$ oo rm 1.12.5                                                                                                                                                                          1 ↵ (go1.4 [email protected]) ~/github/oo/versions/1.5/src
[email protected] removed

You may need to download a prebuilt golang on the first run, if there's no golang installed, bootstrap won't work.

Using Prebuilt

By default, oo prefers to bootstrap a new version via an existing installed version:

$ oo get 1.12.6
get https://codeload.github.com/golang/go/tar.gz/go1.12.6..
######################################################################## 100.0%
using go1.12.5 to bootstrap go1.12.6....
build successfully
=> go1.12.6

But we are still able to download a prebuilt packages directly from https://golang.org/dl/ without a build waiting:

$ oo get 1.10.3 --use-prebuilt
get https://dl.google.com/go/go1.10.3.darwin-amd64.tar.gz..
######################################################################## 100.0%
=> go1.10.3

                             default: https://dl.google.com/go/go%s.%s-amd64.tar.gz
                             The first parameter here is version, the second is platform.

Version: 0.0.7

Custom Mirror

To use custom mirror url to download golang source:

$ export OO_MIRROR_PATTERN='https://storage.googleapis.com/golang/go%s.src.tar.gz'
$ oo get 1.12.6
get https://storage.googleapis.com/golang/go1.12.6.src.tar.gz..
##########                                                                14.4%

To use custom mirror url to download prebuilt golang package:

$ export PREBUILT_PKG_URL_PATTERN=https://dl.google.com/go/go%s.%s-arm64.tar.gz
$ oo get 1.16.3 --use-prebuilt
get https://dl.google.com/go/go1.16.3.darwin-arm64.tar.gz..
########################################################################################################################################################################################################################## 100.0%
=> go1.16.3

You can add these environment variables to your bashrc or zshrc etc. for convenience.

Troubles

If there are any errors during the bootstrap building, it's helpful to build manually to check what errors occurred:

cd path/to/oo/versions/x.x.x/src
GOROOT_BOOTSTRAP=path/to/downloaded/go ./all.bash
