Introduction

The semantic index are a set of stratego libraries, java primitives and editor extensions that provide a language-parametric framework for doing name binding, scoping, incremental analysis and incremental compilation.

Quick start

To be able to use the index a nightly version of Spoofax is required which can be retrieved from the following update site:

   http://www.lclnet.nl/update/nightly

The simplest place to get an example on what the index can do and how a project using the index looks like is generating a new Spoofax project. Go to File->New->Project, choose "Spoofax editor project" and fill in Entity as the language name. This will generate and build a Spoofax example project for you that uses the index. To test it out open up test/example.ent and try some things like resolving a reference, code completion and introducing errors by changing types to types that do not exist. These features are all provided by the index using naming annotations in the SDF file and Stratego code to fill in some gaps in the generic algorithm. The tutorial will go into more detail on how to define these things yourself.

More complex examples using the index are also available. We've prototyped a mini C# subset, a C subset without macros and the entity language with functions and aspects. To get these examples download this archive^?, extract it somewhere, import the projects into an Eclipse workspace and build all projects (ctr+b).

Tutorial

In this tutorial we will explain how the example entity language uses the index and how to extend it with functions and simple expressions.
