Dangerfile

# This is an example Dangerfile containing many useful examples of what can be done with Danger

# Make sure you read every comment (#) to enjoy proper Danger setup
# Every part of this setup is optional, so pick, remove, adjust and add as you need
# You can remove the comments afterwards

# To setup Danger with repo on Github.com you need to add DANGER_GITHUB_API_TOKEN for a user to your CI secret and expose it for PRs

# To setup Danger on enterprise Github, you need to also add these environment variables:
# DANGER_GITHUB_HOST=git.corp.goodcorp.com - host that the Github is running on
# DANGER_GITHUB_API_BASE_URL=https://git.corp.goodcorp.com/api/v3 - host at which the Github API is reachable on

# To setup Danger for Slack, you need to add SLACK_API_TOKEN to your CI secrets - a token for a bot user on Slack

# Check env variable:

 return env.nil? || env.empty?
