can use repo-defined environment variables (travis settings page for my repo) in my notification section of .travis.yml? Something like this:
notifications:
slack:
rooms:
- myworkspace:${TRAVIS_SLACK_TOKEN}#myroom
on_success: ${TRAVIS_SLACK_ON_SUCCESS}
on_failure: always
email:
recipients:
.
.
on_success: ${TRAVIS_EMAIL_ON_SUCCESS}
on_failure: always
