CI: GitHub Actions

[azu]

We can move to GitHub Actions from Travis CI and Appveyor.

GitHub Action do 20 workflows concurrently.

You can execute up to 20 workflows concurrently per repository.

It will improve testing performance.

Rough Image:

• Move Unit/E2E test to GitHub Action from Travis CI/Appveyor
  • => Drop to use Appveyor(Delete appveyor.yml and stop to use it)
• Preserve deploy script on Travis CI

Finally, we use GitHub Action and Travis CI(deploy website)?

It is difficult that move Deploy Script(Build Website and deploy to gh-pages) to GitHub Actions.

• textlint/.travis.yml

  Lines 45 to 54 in e77f213

  	- stage: deploy
  	node_js: stable
  	if: branch = master AND type != pull_request
  	install:
  	- yarn install --frozen-lockfile
  	- yarn run bootstrap --scope textlint-website
  	before_script:
  	- $(npm bin)/set-up-ssh --key "$encrypted_6407ccbe9d33_key" --iv "$encrypted_6407ccbe9d33_iv" --path-encrypted-key ".travis/textlint.github.io-deploykey.enc"
  	script:

Because GITHUB_TOKEN of GitHub Actions does not support gh-pages yet.

• Cannot deploy with GITHUB_TOKEN for new repository · Issue #9 · peaceiris/actions-gh-pages

• Need to compare performance

Currently, Travis CI take 10 min.
(Mostly, Appveyor finish faster than Travis CI)

@azu
I tried it in my forked repository Kesin11#1
Some config like job/step name are different, but env matrix is same as you suggested.

Performance

Almost jobs that include macVM took about 6 to 7minutes.

Test result

Linux and macOS are OK. But windows is failed.
I also try windows server 2019 with windows-latest but there was no change.

1. node 8 version problem.
   Run yarn install --frozen-lockfile failed only windows & node8 environment.
   actions/setup-node with windows using old node 8.10. 😥 It different from other OS.
   It looks bug of github VM environment.
   Node 8 installs different versions depending on system actions/setup-node#27

2. prettier error
   prettier output error only windows & node 10,12 matrix like this

D:\a\textlint\textlint\packages\@textlint\fixer-formatter\test\fixtures\double.js
##[error]   1:26  error  Delete `␍`  prettier/prettier

I don't know why it is. I'm not familiar with prettier and windows.

In my opinion, split workflow that test windows from Linux and macOS.
In the Windows environment, some workarounds may be required.

Almost jobs that include macVM took about 6 to 7minutes.

Yeah! Good perf.

Test result

Nice reasearch!
Both problem is related with Windows 😢

So, I propose that we do following step.

At first step, we add GitHub Action without Windows like os: [macOS-10.14, ubuntu-18.04]
In next step, we try to add windows support.

[azu]

@Kesin11 Can you submit PR without windows support?

[Kesin11]

Thank you for the review.
I'll do it today.

Just enforce LF via a gitattributes file and everything should be OK on Windows too.
