description: Build and test a stack-based Haskell project
inputs:
  working-directory:
    description: |
      Working directory for run commands
  test:
    description: |
      Whether to run tests
    default: true
  stack-arguments:
    description: |
      Additional arguments for all top-level `stack` command invocations.
    default: "--no-terminal"
  stack-query-arguments:
    description: |
      Additional arguments in `stack query` invocations.
  stack-path-arguments:
    description: |
      Additional arguments in ``stack path`` invocations.
  stack-setup-arguments:
    description: |
      Additional arguments in `stack setup` invocations.
  stack-build-arguments:
    description: |
      Additional arguments for all `stack build` invocations.
    default: "--fast --pedantic"
  stack-build-arguments-dependencies:
    description: |
      Additional arguments passed after `stack-build-arguments` in `stack build`
      invocations on the _Dependencies_ step.
  stack-build-arguments-build:
    description: |
      Additional arguments passed after `stack-build-arguments` in `stack build`
      invocations on the _Build_ step.
  stack-build-arguments-test:
    description: |
      Additional arguments passed after `stack-build-arguments` in `stack build`
      invocations on the _Test_ step.
  cache-prefix:
    description: |
      Prefix applied to all cache keys. This can be any value you like, but
      teams often use `v{N}` and bump it to `v{N+1}` when/if they need to
      explicitly bust caches.
  cache-save-always:
    description: |
      Save artifacts to the cache even if the build fails. This may speed up
      builds in subsequent runs at the expense of slightly-longer builds when a
      full cache-hit occurs. Since `@v4.2.0`.
    default: false
  on-dirty-files:
    description: |
      What to do if we find changes to the cabal or lock file after a build.
      Value can be `warn`, or `error`. Default is `warn`.
    default: warn
  install-stack:
    description: |
      Install stack, if necessary
    default: true
  upgrade-stack:
    description: |
      Upgrade stack
    default: true
  compiler-tools:
    description: |
      A list of packages to install as compiler tools, one per line. This is
      useful to do here rather than separate `run` commands so that their
      installation is incorporated in the dependency cache. Since `@v5.2.0`.
  stack-yaml:
    description: |
      **Deprecated** use `env.STACK_YAML` or `stack-arguments` instead.
runs:
  using: "node20"
  main: "dist/index.js"
