GitHub Actions - #238

Hello. Thanks for opening a pull request. I would like to understand the changes. Why is it necessary to update the CI?

The current CI:

• Is pretty fast anyway. Multiple PRs can also run parallel builds.
• We do not configure CI very often.
• Travis continues to remain free for open-source projects, albeit with new limitations.

Would like to know if there is an existing precedent, e.g. other atom language repos have migrated to github actions.

Hello. Thanks for opening a pull request. I would like to understand the changes. Why is it necessary to update the CI?

Hi. I mentioned the reasons for this change in the above post:

• GitHub Actions is much faster than the other CI services and allows parallel runs
• GitHub Actions is much easier to configure.
• Atom is a GitHub product, so we should use GitHub Actions.
• Travis is making its services limited and monetary: https://blog.travis-ci.com/2020-11-02-travis-ci-new-billing

Extra points:

• The Travis/Appveyor script does not show what exactly is running (running some bash script from somewhere else). Using GitHub Actions this becomes very obvious
• GitHub Actions is a unified place. No need for two different files for different operating systems.

The current CI:

• Is pretty fast anyway. Multiple PRs can also run parallel builds.

• AppVeyor does not allow parallel builds, and it is painfully slow.
• Travis CI is slower when you compare it with GitHub Actions

• We do not configure CI very often.

I know, but it needs to be updated at some point.

My PRs to language-* packages all fail because Travis is outdated. See this for an example:
atom/language-python#325

• Travis continues to remain free for open-source projects, albeit with new limitations.

But Atom is a GitHub product, it is hosted on GitHub. It is much more natural to use something from GitHub itself.

Would like to know if there is an existing precedent, e.g. other atom language repos have migrated to github actions.

An example of a project that currently use it:
https://github.com/atom/github

I use GitHub Actions in all the projects at @atom-ide-community, so we have battle-tested these in our organization.

I have opened PRs for a dozen of the language repos.
