com-lihaoyi/acyclic

This system is a Scala compiler plugin designed to detect and prevent cyclic dependencies in codebases. It provides graph analysis algorithms to identify cycles and strongly connected components, enforcing acyclic structures during compilation. The tool supports both Scala 2 and Scala 3 versions and includes comprehensive test infrastructure to validate its cycle detection logic.

The acyclic compiler plugin has been ported to support Scala 3 (including versions 3.4.x and 3.5.0) while maintaining compatibility with Scala 2.11, 2.12, and 2.13. The codebase is now organized into version-specific source directories (\src-2\ for Scala 2 and \src-3\ for Scala 3) with shared logic in \src\ and compatibility shims in \src-2.11\, \src-2.12\, and \src-2.13\. The plugin now uses the \dotty.tools.dotc\ compiler internals for Scala 3 and \tools.nsc\ for Scala 2, allowing users to enforce acyclic dependencies in both Scala 2 and Scala 3 projects.

The 'sinject' plugin, which previously injected implicit parameters into classes marked with the @sinject.Module annotation, has been removed from the codebase. This change eliminates the automatic modification of class constructors and templates during the compilation phase, meaning users will no longer receive implicit binding module injections via this compiler extension.

plugin/src · high confidence

The \Module\ annotation class, previously defined in \plugin/src/sinject/Runtime.scala\, has been removed from the plugin. This eliminates the \sinject.Module\ type that users could apply to their code to mark modules for dependency injection.

The project has migrated its build system from SBT to Mill, now using version 1.0.5 (specified in .mill-version). The build configuration is now defined in build.mill, which sets up cross-compilation for Scala versions 2.11 through 3.8 and configures publishing to the Sonatype Central Portal. The Java runtime requirement is explicitly set to Temurin 17 via .mill-jvm-version. Additionally, scalafmt has been updated to version 3.8.1 with a new configuration file (.scalafmt.conf) that enforces Scala 3 dialect for .mill files and src-3 sources, and the MIT license file has been added to the repository.

The repository now includes a new GraphAnalysis module that provides algorithms for detecting cycles and strongly connected components within dependency graphs. This logic, implemented in GraphAnalysis.scala, supports finding the smallest cycle starting from a specific node and identifying strongly connected components via depth-first search, which are core capabilities for the acyclic plugin's functionality.
