TCS Tookit Sample Project Tutorial

This wiki page is a tutorial to help for using the first beta version of the TCS Toolkit. The TCS Toolkit is available for download here.


You should have installed the ATL and AM3 plugins and the ant-contrib extension for ant (see documentation).


This section is under construction. Here are some quick notes.

The project "TCSSample" contains two folder:

  • TCSToolkit contains all the required files for using TCS
  • SampleDSL contains a complete example of use case for TCS

Listing of SampleDSL folder:

  • Metamodel/AddressBook.km3: AddressBook metamodel in KM3 syntax
  • Metamodel/AddressBook.ecore: AddressBook metamodel
  • SampleExtraction/build.xml: Ant script for AddressBook extraction (model to text)
  • SampleExtraction/sample.adb.ecore: sample model (to test extraction)
  • SampleInjection/build.xml: Ant script for AddressBook injection (text to model)
  • SampleInjection/sample.adb: sample file using AddressBook grammar (to test injection)
  • TCS/AddressBook.tcs: TCS file for AddressBook
  • TCS/AddressBook-importer.jar: AddressBook injector
  • TCS/AddressBook.tcs.ecore: AddressBook extractor
  • SampleDSL_ExtractorCreation.xml: Ant script to create AddressBook extractor
  • SampleDSL_InjectorCreation.xml: Ant script to create AddressBook injector


This section is under construction. Here are some quick notes.

First Step: Setup OK?

If you have installed all required plugins and imported the example project into Eclipse, try the following steps in the SampleDSL-folder in order to verify that your environment is set up correctly and you get no errors:

  1. Extract the ecore file from the AddressBook.km3. Add temporarily a new attribute (e.g. the line attribute faxNumber: String; to the Contact class), update the Ecore via context menu and Inject KM3 to Ecore metamodel and check that your new attribute appears in the AddressBook.ecore tree editor.
  2. Right click on TCSSample/SampleDSL/Metamodel/AddressBook.ecore and select Register Metamodel. If you don't do this, the generic Ecore Editor for the Model file sample.adb.ecore will not find the metamodel and reports an error!
  3. Run the ant scripts SampleDSL_ExtractorCreation.xml and SampleDSL_InjectorCreation.xml. Initially, you have to open the Run As > Ant Build... dialog and select Run in the same JRE as the workspace under the JRE tab.
  4. Test the SampleInjection and SampleExtraction. Run the build.xml as Ant Build and check that the output file was (re)generated (sample.adb.ecore for Injection, sample.adb.ecore.adb for Extraction). Play around with it, change some entries, regenerate and watch the result.

Second Step: How to use this Sample Project for my own DSL?

First, you should create your metamodel by using the KM3 syntax. Next, you should generate the corresponding Ecore metamodel with the KM3 action "Inject KM3 to Ecore metamodel" available in the context menu. Then, you can create the textual concrete syntax (the tcs file) for your DSL.

Now, you are ready to generate the injector and the extractor for your DSL by using the generic Ant scripts available.
