Masking: Kotlin Compiler Plugin (Not Finished)

Exploring Kotlin compiler plugins. This is just an experiment.

This plugin outputs the additional text for each called method with an annotation The annotation could be default "Masking" or any user provided as a gradle parameter. When nothing is provided, compiler uses default which will be added project via Gradle sub-plugin

This whole thing is inspired by this talk and some parts of the code are from the sample (video), kudos Kevin!

TODO

Compiler also need to mask the user input for example by rewriting toString bytecode. Asterisks is an optional paramter and user can change it

data class User(
    val name: String,
    @Masking val password: String
)
println(User("First Name", "PassW0rD"))

should output

User(name=First Name, password=****)

Usage

Plugin is not published anywhere you can just pull this repo and run it. For now the root gradle file substitutes remote modules by local modules.

project build.gradle:

buildscript {
  dependencies {
      classpath "me.tatocaster.masking:masking-gradle-plugin:0.5.0"
  }
}

module build.gradle

apply plugin: "me.tatocaster.masking.gradle.plugin"

maskingGradlePlugin {
    enabled = true // required
    mask = "*" // optional, not working for now
//    maskingAnnotation = "me.tatocaster.masking.sample.CustomMasking"
    // if not specified then use "Masking" default annotation
}

and of course Needs tests
