Revision as of 00:15, 30 December 2016 by Unnamed Poltroon (Talk) (Added info about description() and MoML.)
One idea is to use Xtext to describe models textually. See Triquetrum Command Language (github issue)
Below are various references:
- Ptcl was a Tcl-based language for Ptolemy Classic. The ptcl manual might be of use to help define some of the Xtext commands. For example, both will need to connect ports from an outer composite to an inner composite.
- The NamedObj class in Ptolemy II has a description() method that describes a model. For example $PTII/ptolemy/actor/test/CompositeActor.tcl has a test that invokes description() on a model. The description() functionality is little used and has been replaced with MoML.
- Ptolemy II uses MoML (Modeling Markup Language) to store models on disk. See Heterogeneous Concurrent Modeling and Design in Java (Volume 1: Introduction to Ptolemy II), Chapter 7, MoML. See also 5.8 What file format are the models stored in?. In particular, note that the MoML description is not a complete description because the actors may be defined in Java or MoML and the definitions may be overwritten.
- Hallvard Traetteberg visited the Ptolemy group in 2012-2013 and did a first cut of creating Ptolemy II OSGi bundles. Hallvard also developed some Xtext work, see https://github.com/hallvard/ptolemy. Hallvard has not been using Ptolemy much recently, but his work is there.
- Eclipse Layout Kernel (Elk) has Issue #101 Implemented a textual format for ElkGraph. Ptolemy II uses an automatic layout mechanism called Kieler, which is related to Elk.
