Minimal template to play with the scalameta semantic API

To run this project, execute

git clone https://github.com/scalameta/sbt-semantic-example`
cd sbt-semantic-example
sbt analyzer/run

That should print out something like this

analyzeme/src/main/scala/Test.scala

Project Overview

This repository provides a minimal template to play with the new approach to semantic APIs proposed by Scalameta. Prominent parts of the project include:

• plugins.sbt that enables the sbt-buildinfo plugin responsible for passing a --sourcepath and --classpath to the analyzer project.
• build.sbt that shows how to install semanticdb-scalac and how to pass the --sourcepath and --classpath to analyzer/run.
• analyzeme/src/main/scala/Test.scala an example file that we want to analyze with the Semantic API.
• analyzer/src/main/scala/Main.scala that demonstrates how to load a scala.meta.Database.
