libphonenumber-js/runnable/metadata-pull-request.js

A simpler (and smaller) rewrite of Google Android's popular libphonenumber library

// In order for this script to work:
//
// * Install `hub`: `brew install hub`
// * Create a "Personal Access Token" in GitHub account settings (just "repo_public" would be enough)
// * Tell `hub` to use the token for creating GitHub pull requests: `echo "---\ngithub.com:\n- protocol: https\n  user: GITHUB_USERNAME\n  oauth_token: TOKEN" >> ~/.config/hub`

	metadata_branch_exists = true
}
catch (error)
{
	if (error.message.indexOf('fatal: Needed a single revision') === -1)
	{
		throw error
	}
}

// If no `update-metadata` branch exists
// then it simply means that metadata hasn't changed.
