Generic IDEA Plugin for Scala Macro Support

This is an experimental project to add Scala macro support to IntelliJ IDEA for any macro.

TODOs

• Currently, the communication between the macro and this plugin uses reading and writing of XML files. This is not ideal performance-wise.
• This solution only works for macros which transform/generate class members/companion object members of the annotated class. Maybe it could be expanded to work on a wider range of macros
• Remove all mentions of Silicon, as this project can be used independently of Silicon.

Usage

On the Macro Side

• Build your custom macro for your Scala project using the template found in macro/template.scala.
• The method saveConfig from the template saves all relevant data to a directory called .plugin in your Scala project.

On the Plugin Side

• Compile the plugin using sbt packagePlugin.
• The compiled plugin is ready to be installed in target/plugin/silicon-idea/lib/siliconIdeaPlugin.jar.
• To install, inside IntelliJ: Preferences -> Plugins -> Install plugin from disk
• If the plugin is correctly installed, the .plugin directory is read and IntelliJ should not highlight your macro usages as errors.
