# This .travis.yml is modified from the sample at

# Use new container infrastructure to enable caching

# Do not choose a language; we provide our own build tools.
language: generic

# Caching so the next build will be fast too.
cache:
  directories:
  - $HOME/.ghc
  - $HOME/.cabal
  - $HOME/.stack

# The different configurations we want to test. We have BUILD=cabal which uses
# cabal-install, and BUILD=stack which uses Stack. More documentation on each
# of those below.
#
# We set the compiler values here to tell Travis to use a different
# cache file per set of arguments.
#
# If you need to have different apt packages for each combination in the
# matrix, you can use a line such as:
#     addons: {apt: {packages: [libfcgi-dev,libgmp-dev]}}

# fast_finish: build successful when every builds not in allow_failure are finished
# i.e. not waiting any of the allow_failure to finish
