| # To dynamically create a build matrix, we generate a JSON output from one job | |
| # and use fromJson in the next job to construct the matrix. | |
| # This dynamic approach means we don't have to update the CI file when we | |
| # change supported GHC versions. | |
| # | |
| # Only the Cabal build job will use the generated matrix, since Stack has a | |
| # pinned GHC version in the stack.yaml file. | |
