.travis.yml

# This is the complex Travis configuration, which is intended for use
# on open source libraries which need compatibility across multiple GHC
# versions, must work with cabal-install, and should be
# cross-platform. For more information and other options, see:
#
# https://docs.haskellstack.org/en/stable/travis_ci/
#
# Copy these contents into the root directory of your Github project in a file
# named .travis.yml

sudo: false

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

# 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]}}
