@JLHwung shows me the Test262 automation as a model for this one:

• Fetch the last commit
• If different from the current then execute the rest
• Update the commit sha in the ./packages/babel-compat-data/download-compat-table.sh
• Commit changes
• Create a pull request

A word about testing: nothing in the scripts folder was tested. I'd like to create a sub-folder test and add a test for the js script. WDYT?

Hi there 👋

I finally use the action/checkout to get the last commit from kangax repo.

I add a compare script to check if it's relevant to update or not. If commits are equal it throws.

To wrap up:

• I get the last commit from kangax repository
• I compare it with the current we have
• If it's okay, I update the bump-data-compat-version.sh script
• Then I run it.

I don't think that we need this step; we don't have it for the parser tests updater.

Thanks for your feedback @nicolo-ribaudo 🙌 :)

My initial was to avoid useless computations, doesn't that make sense?

[nicolo-ribaudo]

Since this script and bump-data-compat-version.sh are not used anywhere else, we could just inline them in the action as a single step:

      - name: Update to latest kangax/compat-data commit
        run: perl -i -pe 's/^COMPAT_TABLE_COMMIT.+$/COMPAT_TABLE_COMMIT='$(git rev-parse FETCH_HEAD)'/' ./packages/babel-compat-data/download-compat-table.sh
        with:
          GIT_DIR: ./packages/babel-compat-data/build/compat-table

I think it is good to leave it as-is: It is more convenient to debug the update workflow in local machine.

I'm okay with the bot approach here ^^

This works!

I'm merging this to test if it also works in this repo, or if there are any permissions problems.
