Plugin architecture for custom code generation about scalapb HOT 2 CLOSED

Hi Per,

The place to start with is at:
https://github.com/trueaccord/ScalaPB/blob/master/compiler-plugin/src/main/scala/com/trueaccord/scalapb/compiler/Process.scala

In runWithInputStream the request from protoc (in form of a
CodeGeneratorRequest) is parsed and passed to ProtobufGenerator.

protoc supports invoking multiple plugins in a single run. In Process.scala
there is a trick that we do to make protoc send the CodeGeneratorRequest
back to the JVM that invoked it (which is done differently for Windows and
Linux/Mac), but it would be fairly straightforward to extend the trick to
handle multiple plugins...

Since I have all my messages as photo I would like to take advantage of
that and generate all boiler plate code for my application.

Examples of generated code other than plain case classes:

• Custom JSON ser / dser
• Slick table models
• Web forms with input validation

What I'm looking for here is an easy way of pluggin my own custom code
generator into ScalaPB's pipeline.

Any thoughts on that? How hard is it to do this today if I fork the
project?

ScalaPB uses a new SBT plugin sbt-protoc, which allows creating custom generators.
