# 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:
 - CABALVER=1.18 GHCVER=7.8.1  # see note about Alex/Happy for GHC >= 7.8
 - CABALVER=1.18 GHCVER=7.8.2
 - CABALVER=1.18 GHCVER=7.8.3
 - CABALVER=1.22 GHCVER=7.10.1
 - CABALVER=head GHCVER=head   # see section about GHC HEAD snapshots

# We have to allow lvish 1.1.4 to fail with these two, since it requires an earlier version of base.
