sbt-semantic-example's Introduction

Minimal template to play with the scala.meta semantic API

To use this project

$ git clone https://github.com/scalameta/sbt-semantic-example
$ cd sbt-semantic-example
$ sbt app/run

That should print out something like this

library/src/main/scala/Test.scala
---------------------------------
Dialect:
Scala211

Names:
[7..11): Test => _empty_.Test.
[20..29): printList => _empty_.Test.printList()V.
[33..37): Unit => _root_.scala.Unit#
[46..53): println => _root_.scala.Predef.println(Ljava/lang/Object;)V.
[54..58): List => _root_.scala.collection.immutable.List.

Denotations:
_empty_.Test. => final object Test
_empty_.Test.printList()V. => def printList: ()Unit

Sugars:
[58..58) [Int]

_root_.scala.Predef.println(Ljava/lang/Object;)V.

Edit Test.scala and run again.

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 scalahost compiler plugin responsible for generating and persisting semantic databases.
build.sbt that shows how to use scalahost as a library to create a Mirror from a previously persisted semantic database and run semantic operations on the corresponding Scala code.
library/src/main/scala/Test.scala an example file that we want to analyze with the Semantic API.
app/src/main/scala/Main.scala that demonstrates how to load a Mirror, which is an implementation of the Scalameta Semantic API.
