## Testing

# Set the language to Ruby so that we can run sass-spec tests.
language: ruby

# support configuration-specific imports with the new front-end.

## Deployment

jobs:
  include:
  - stage: deploy
    if: (type IN (push, api)) AND (repo = sass/dart-sass) AND tag =~ ^\d+\.\d+\.\d+([+-].*)?$
    env: DART_CHANNEL=dev DART_VERSION=2.0.0-dev.36.0
    script: skip # Don't run tests

    deploy:
      # Deploy to GitHub, npm, pub, Homebrew, and Chocolatey.
      provider: script
      script: tool/deploy.sh

      # Don't clean up the Dart SDK.
      skip_cleanup: true

      # This causes the deploy to only be build when a tag is pushed. This
      # is because the `tag` attribute in `if:` statements has a different
      # understanding of the "current tag" than this, which uses the
      # `TRAVIS_TAG` environment variable. `if:` statements check whether a
      # tag exists that refers to the current commit, whereas `TRAVIS_TAG`
      # checks whether the current build was caused by a tag.
      #
      # We check `if:` because it avoids unnecessary build steps, and
      # `on: {tags: true}` ensures that we only deploy on the build caused
      # by pushing a tag, not the build caused by pushing master.
      on: {tags: true}
