| # This workflow defines two different jobs that are very similar: | |
| # nix-commit-from-ci and nix-commit-from-flake-lock. | |
| # | |
| # The difference is what version of stacklock2nix is used in the | |
| # my-example-haskell-lib-easy/flake.lock and | |
| # my-example-haskell-lib-advanced/flake.lock files. | |
| # | |
| # nix-commit-from-ci uses the stacklock2nix dependency from the code that is | |
| # running through CI. This is what you'd expect to be tested. | |
| # | |
| # nix-commit-from-flake-lock uses the version of stacklock2nix that is locked | |
| # in the respective flake.lock files. | |
| # | |
| # This is only necessary because Nix's relative-path support for flakes is broken: | |
| # | |
| # - https://github.com/NixOS/nix/issues/3978 | |
| # - https://discourse.nixos.org/t/relative-path-support-for-nix-flakes/18795 | |
| # | |
| # Because Nix's relative-path support for flakes is broken, the | |
| # my-example-haskell-lib-easy/flake.lock and | |
| # my-example-haskell-lib-advanced/flake.lock files are locked to | |
| # the upstream stacklock2nix repo on GitHub, instead of just the repository top-level | |
| # flake.nix. | |
| # | |
| # It is necessary to test these two Haskell projects against the version of | |
| # stacklock2nix that is locked in the two flake.lock files because end-users | |
| # might try to directly use one of the Haskell projects without updating the | |
| # stacklock2nix to the latest version. The expectation is that they will | |
| # work as-is. | |
