# (1) remember to use 'brew cleanup -s' at the end of the travis script;
# otherwise, the $HOME/Library/Caches/Homebrew folder will be enormous
# (~2GB for the 4 jobs). This is because this folder is already present on
# osx images and it is big.
# (2) For a time, I had removed $HOME/.cache/Homebrew (cache of Linuxbrew)
# because it was also storing some logs in $HOME/.cache/Homebrew/Logs, making
# the cache rebuilt every time.
cache:
  directories:
    - "$HOME/.cache/pip"
    - "$HOME/.gem/ruby"
    - "$HOME/Library/Caches/Homebrew" # (1)
    - "$HOME/.cache/Homebrew" # (2)

# This is done to ensure that the formulas that kong.rb depends on
# are picked up by the currently-tested branch.

  - mkdir -p $(brew --repo)/Library/Taps/kong
