koron/goup

Utility to download, extract and switch released go versions on Windows.

Getting started

Check stable go releases.

> goup remotelist
Remote Version:
  go1.13.7
  go1.12.16

Check all go releases.

> goup remotelist -all
Remote Version:
  go1.13.7
  go1.12.16
  go1.13.6
  go1.13.5
  go1.13.4
  (...snip...)
  go1.3.1
  go1.3
  go1.2.2
  go1
  go1.14beta1

Install (=download and extract) a go archive.

> goup install -root C:\golang go1.13.7

List installed go.

> goup list -root C:\golang
Local Version:
  go1.12.16.windows-amd64
  go1.13.7.windows-amd64

Switch go version. This requires symbolic link to directory, so you may need to install "Windows Developer mode".

> goup switch -root C:\golang go1.13.7
go1.13.7.windows-amd64

> dir C:\golang
 Volume in drive C has no label.
 Volume Serial Number is DEAD-BEEF

 Directory of C:\golang

2020/02/03  00:42    <DIR>          .
2020/02/03  00:42    <DIR>          ..
2020/02/03  00:42    <SYMLINKD>     current [go1.13.7.windows-amd64]
2020/02/02  18:48    <DIR>          dl
2020/02/02  18:48    <DIR>          go1.12.16.windows-amd64
2020/02/02  18:47    <DIR>          go1.13.7.windows-amd64
               0 File(s)              0 bytes
               6 Dir(s)  999,999,999,999 bytes free

Now C:\golang\current is a symblic link to go1.13.7's dir. You can add C:\golang\current\bin to PATH env, to run go command.

GOUP_ROOT env works as instead of -root C:\golang option.

Environment variables

• GOUP_ROOT - root dir to install.

  GODL_ROOT can be used for same purpose but it is obsoleted. It will be removed at future release.

• GOUP_LINKNAME - name of symbolic link for active version.

  Default is current but you can override it by this.
