scalamacros/paradise

This system is the Macro Paradise compiler plugin for Scala 2.12, designed to enable macro annotations and ensure their expanded definitions are visible in the REPL. It provides the core infrastructure to detect, validate, and expand macro annotations during the type-checking phase, including support for REPL integration and comprehensive error handling for invalid usage. The project is maintained as a legacy release for Scala 2.12.x, with a build system configured for publishing artifacts to Sonatype.

The repository was initialized with core build configuration, documentation, and licensing for the Macro Paradise plugin. A comprehensive test suite was established to verify macro annotation behavior, covering positive execution scenarios, negative validation cases, and specific edge cases involving scopes and module classes.

This period focused on implementing core macro annotation expansion and validation logic within the typechecker, alongside integrating the plugin with the Scala REPL to ensure expanded definitions are visible. The work was supported by extensive test coverage addressing various edge cases, including import handling, companion object resolution, and specialized implicit classes. The period concluded with a migration of the build system to SBT and an update to Scala 2.12.21.

The repository has been initialized with the core structure for the Macro Paradise plugin, including a .gitignore file to exclude build artifacts, an .sbtrc configuration for sbt project navigation, and a BSD-style LICENSE.md file. The README.md provides user-facing documentation explaining that the plugin is no longer actively developed for Scala 2.13 (where functionality is built-in) but continues to release for Scala 2.12.x, along with instructions for cutting releases using sbt and GPG signing.

The plugin now includes the core typechecker components required to support macro annotations. This adds logic to detect, validate, and expand macro annotations during the type-checking phase. Specifically, it introduces validation rules ensuring macro annotations are static, not inherited, and have the correct method signature, along with error reporting for invalid shapes or usage contexts. The expansion engine handles the transformation of annotated definitions, including support for top-level classes and modules, and integrates with the REPL to make expanded definitions visible.

The Macro Paradise compiler plugin now supports macro annotations and ensures that definitions produced by macro expansions are visible in the Scala REPL. This is achieved by adding a REPL integration layer that updates the interpreter's internal member handlers and referenced names when macros expand, fixing issues where REPL users could not see or use symbols generated by macros. Additionally, the plugin now includes infrastructure for handling macro annotation detection and tree manipulation via new reflection traits.

Added macro annotation test suite; Added negative tests for macro annotation validation and error handling; Added run-time tests for macro annotation behavior; Added test cases for module-class annotation behavior; Added test for issue \#42: specialized implicit class; Added test for issue \#46 regarding unused imports and variance annotations; Added test for issue \#64 regarding annotated traits; Added tests for Scaladoc annotation expansion; Added tests for annotation macro handling of import contexts; Added tests for annotation processing in issue48; Added tests for companion object symbol resolution; Added tests for macro annotation scopes and acyclic dependencies.

The project build has been migrated to SBT, establishing Scala 2.12.21 as the default compiler version. This change introduces a new build structure with dedicated projects for the compiler plugin, sandbox, and tests, and configures artifact publishing to Sonatype Central Snapshots.
