# The following enables several GHC versions to be tested; often it's enough to test only against the last release in a major GHC version. Feel free to omit lines listings versions you don't need/want testing for.
env:
 - GHCVER=7.4.2
 - GHCVER=7.6.3
 - GHCVER=7.8.1

# Note: the distinction between `before_install` and `install` is not important.

 - sudo apt-get update
 - sudo apt-get install cabal-install-1.18 ghc-$GHCVER happy

install:
 - cabal-1.18 update
 - cabal-1.18 install --only-dependencies --enable-tests --enable-benchmarks

# Here starts the actual work to be performed for the package under test; any command which exits with a non-zero exit code causes the build to fail.
script:
 - cabal-1.18 configure --enable-tests --enable-benchmarks -v2  # -v2 provides useful information for debugging
 - cabal-1.18 build   # this builds all libraries and executables (including tests/benchmarks)
 - cabal-1.18 test
 - cabal-1.18 check
 - cabal-1.18 sdist   # tests that a source-distribution can be generated

# The following scriptlet checks that the resulting source distribution can be built & installed
