semanticdb-for-scala3

The project that generates Scala codes from semanticdb.proto for Scala3 compiler. Context: scalameta/scalameta#2367

• Generate Scala code from semanticdb.proto using Scalapb
• Adjust the generated codes for Scala3
  • Remove scalapb-runtime dependencies so Scala3 doesn't need to depend on scalapb-runtime.
  • Replace annotations @transient to @sharable, remove SerialVersionUID
  • derive CanEqual for generaged class and traits.

Usage

• clean-generated: delete generated files.
• generate: generate Scala files and adjust them for Scala3 compiler.

Workflow

$ sbt
> clean
> clean-generated
> generate

Updating the .proto to match a certain Scalameta version

• Update the scalametaVersion variable in build.sbt, or the semanticdbProtoURL.
• Run sbt generate, to re-fetch and patch the local .proto file.
