# NB: don't set `language: haskell` here
# 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.
- GHCVER=7.6.3
- GHCVER=7.8.2 # see note about Alex/Happy
# - GHCVER=head # see section about GHC HEAD snapshots
# Note: the distinction between `before_install` and `install` is not important.
- travis_retry sudo add-apt-repository -y ppa:hvr/ghc
- travis_retry sudo apt-get update
- travis_retry sudo apt-get install cabal-install-1.18 ghc-$GHCVER # see note about happy/alex
- export PATH=/opt/ghc/$GHCVER/bin:/opt/cabal/1.18/bin:$PATH
- cabal update
- cabal 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.
- cabal configure --enable-tests --enable-benchmarks -v2 # -v2 provides useful information for debugging
- cabal build # this builds all libraries and executables (including tests/benchmarks)
- cabal test
- cabal check
- cabal sdist # tests that a source-distribution can be generated
# The following scriptlet checks that the resulting source distribution can be built & installed
