The Xtext was never checked in to the main Triquetrum repo, instead it is found in

The TriQuetrum Command Language (TqCL) is defined at

  1. Build Triquetrum from Sources.
    1. Instead of using the main Triquetrum repo, use
  2. Check out the branch with: git checkout rtotaro/ft/190/TriquetrumCommandLanguageToPush. There will probably be build errors which are fixed next.
  3. In the project, open the definition and click on "Set as Target Platform". It may take a few minutes for the dependencies to download.
  4. TBD continue with the steps necessary to try it out.


  • See Tqcl for a description of the syntax.
