TCS/Language Project

Revision as of 00:08, 5 October 2007 by Frederic.jouault.univ-nantes.fr (Talk | contribs) (added links to AMMAScripts and AMMACore)

A TCS Language Project is an Eclipse project (typically with the ATL nature), which contains:

  • A KM3 metamodel defining the abstract syntax of the language.
  • A TCS model defining the concrete syntax of the language.
  • Optionally, such a project may also contain:
    • Constraints (e.g., in OCL, as part of an ATL transformation).
    • A compiler (e.g., in ATL, or in ACG).

Creating a Language Project

This section details the steps required to create a language project. Whenever the name of the language appears, we use MyLanguage. The following supposes that you have checked out the AMMAScripts, and AMMACore projects in your workspace.

Creating the Directory Structure

  • Create an ATL project:
    • Open: File->New->ATL Project
    • Name the project like your language (e.g., MyLanguage)
  • Create the following folders and files in your project:
    • MyLanguage/ (this is the project we just created)
      • Metamodel/
        • MyLanguage.km3 (you can copy and paste SampleLanguage.km3 and rename it)
      • Samples/
        • <sample programs written in your language, with the corresponding file extension>
      • Syntax/
        • MyLanguage.tcs (you can copy and paste SampleLanguage.tcs and rename it)
    • build.properties (you can copy and paste /SampleLanguage/build.properties and modify it)

Adding the Language Builder

Building a language involves:

  • Compiling its KM3 metamodel to Ecore.
  • Compiling its TCS model into a parser.
  • Optionally compiling its ACG compiler.

Here are the steps to follow to add the Language Builder to the project:

  • Creating the builder:
    • Right-click on your language project (e.g., MyLanguage) and select "Properties".
    • Go to the "Builders" section.
    • Click "New..."
    • Select "Ant Build"
    • Click "OK"
  • Configuring the builder:
    • Set the name of the builder to "MyLanguage Language Builder"
    • In the "Main" tab:
      • Set "Buildfile" to "${workspace_loc:/AMMAScripts/build.dsl.xml}"
      • Set "Base Directory" to "${workspace_loc:/MyLanguage}"
    • In the "Targets" tab:
      • Set "During a Clean" to target "clean"
    • In the "Classpath" tab:
      • Add all the jars from the "/AMMAScripts/libs/" folder

    • In the "JRE" tab:
      • Check "Run in the same JRE as the workspace"
    • Click "OK"
  • Set the language builder before any other builder
