* Improve support for external Hackage repositories This change builds #535. `repository` blocks in `cabal.project` parsed and `cabal` is used to automatically downloaded them. Then `hackage-to-nix` is used to produce the nix required. To make it work with restricted eval (on hydra for instance) we need to include a sha256 like this: ``` repository ghcjs-overlay url: https://input-output-hk.github.io/hackage-overlay-ghcjs secure: True root-keys: key-threshold: 0 --sha256: sha256-EPlLYPmIGtxeahlOspRzwJv+60N5mqrNC2BY4jZKceE= ``` To find the correct `sha256` put in an invalid one and attempt a build.
Haskell infrastructure test cases
To build the test cases, run from the test directory:
nix-build --no-out-link default.nix
To run all tests (includes impure tests), use the script:
./tests.sh
Generated code
If you change the test Cabal files or need to regenerate the code with
nix-tools, then see regen.nix. Run it like this:
$(nix-build --no-out-link regen.nix)
