So far, /examples was the only place with packages that are built in the CI pipeline.
This change allows us to add package build tests to individual modules at the location where the module is defined. This has several benefits:
- We are not forced to add unnecessary examples in order to maintain test coverage
- When modules get removed, their tests will be removed alongside
- It allows us to keep old modules around and assure they keep working without having to keep outdated examples in /examples
This is to improve package location finding at eval time and script execution time.
Deprecates options lock.{repoRoot,lockFileRel} as well as option eval-cache.{repoRoot, cacheFileRel}
Instead the user must now set:
- paths.projectRoot: pointing to the repoRoot
- paths.package: pointing to the package directory
- paths.projectRootFile can be used to define a marker file to find the project root. The default is '.git' but it could be set to 'flake.nix' for example
- lock files are by default put in the same directory as the package definition
