Print installed version and environment info after installing

[zikaeroh]

With allowed versions like 1.13.x, and potentially latest (#31) / tip (#21) in the future, I'd like to see the action print out the version it installed after it completes. Right now, you just get:

Run actions/setup-go@v1
  with:
    go-version: 1.12.x
/bin/tar xzC /home/runner/work/_temp/a019414e-aed8-4b3a-ab61-ad7003d09d12 -f /home/runner/work/_temp/8575e7d9-8f51-4d45-b8d0-0461f5b12f08
Added matchers: 'go'. Problem matchers scan action output for known warning or error strings and report these inline.

Which says nothing about what actually got installed.

Compare this to travis_setup_go, which will give you:

$ travis_setup_go
go version go1.13.5 linux/amd64
$ export GOPATH="/home/travis/gopath"
$ export PATH="/home/travis/gopath/bin:/home/travis/.gimme/versions/go1.13.5.linux.amd64/bin:/home/travis/bin:/home/travis/bin:/home/travis/.local/bin:/usr/local/lib/jvm/openjdk11/bin:/opt/pyenv/shims:/home/travis/.phpenv/shims:/home/travis/perl5/perlbrew/bin:/home/travis/.nvm/versions/node/v8.12.0/bin:/home/travis/.rvm/gems/ruby-2.5.3/bin:/home/travis/.rvm/gems/ruby-2.5.3@global/bin:/home/travis/.rvm/rubies/ruby-2.5.3/bin:/home/travis/gopath/bin:/home/travis/.gimme/versions/go1.11.1.linux.amd64/bin:/usr/local/maven-3.6.0/bin:/usr/local/cmake-3.12.4/bin:/usr/local/clang-7.0.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin:/home/travis/.rvm/bin:/home/travis/.phpenv/bin:/opt/pyenv/bin:/home/travis/.yarn/bin"
$ export GO111MODULE="on"
$ gimme version
v1.5.3
$ go version
go version go1.13.5 linux/amd64
$ go env
< snipped >

Or for tip:

$ travis_setup_go
go version devel +7d30af8e17 Fri Dec 13 20:41:04 2019 +0000 linux/amd64
$ export GOPATH="/home/travis/gopath"
$ export PATH="/home/travis/gopath/bin:/home/travis/.gimme/versions/go/bin:/home/travis/bin:/home/travis/bin:/home/travis/.local/bin:/usr/local/lib/jvm/openjdk11/bin:/opt/pyenv/shims:/home/travis/.phpenv/shims:/home/travis/perl5/perlbrew/bin:/home/travis/.nvm/versions/node/v8.12.0/bin:/home/travis/.rvm/gems/ruby-2.5.3/bin:/home/travis/.rvm/gems/ruby-2.5.3@global/bin:/home/travis/.rvm/rubies/ruby-2.5.3/bin:/home/travis/gopath/bin:/home/travis/.gimme/versions/go1.11.1.linux.amd64/bin:/usr/local/maven-3.6.0/bin:/usr/local/cmake-3.12.4/bin:/usr/local/clang-7.0.0/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin:/home/travis/.rvm/bin:/home/travis/.phpenv/bin:/opt/pyenv/bin:/home/travis/.yarn/bin"
$ export GO111MODULE="on"
$ gimme version
v1.5.3
$ go version
go version devel +7d30af8e17 Fri Dec 13 20:41:04 2019 +0000 linux/amd64
$ go env
< snipped >

Which gives much more information about the Go environment that the job used.

looking at this next

I fixed this. You can try it out in my branch:

 - uses: actions/setup-go@matcher

Here's what the output should look like:

[ydnar]

@bryanmacfarlane would it be possible to add go-version to the action’s outputs, so subsequent steps (e.g. actions/cache) can use the current Go version as an input?

[bryanmacfarlane]

@zikaeroh - this has been implemented in setup-go@v2-beta. Give it a try

@ydnar - downstream steps can simply run go version and/or which go

[bryanmacfarlane]

Closing since implement. Let me know if you have issues with v2-beta

[sagikazarmark]

@bryanmacfarlane the original post also mentioned the output of go env which is commonly a requested detail in bug reports.

I might be mistaken, but it looks like that hasn't been added. Is that on purpose?

[bryanmacfarlane]

I'll add it under an expando in the logs

[sagikazarmark]

Thanks!

[bryanmacfarlane]

@sagikazarmark - here ya go. in master now. I'll push to v2-beta

[sagikazarmark]

Awesome, thank you! 🎉
