Hi,
I have a few comments on the proposal, as follows:
1) A paragraph in the "Related Issues" section comments on the inability of
Emfatic to adopt any other DSL than the hardcoded Emfatic DSL. That's no
surprise, as Emfatic is not a text-editor-generator, but was itself
generated. If you mention Emfatic at all, please add a link to
http://wiki.eclipse.org/Emfatic where up-to-date information can be found on
the new Emfatic (the one accepted as EMFT component, that improves on the
alphaWorks distribution from a few years ago)
2) In the "Existing Approaches" section, please add a paragraph mentioning
Gymnast Generator, http://wiki.eclipse.org/Gymnast , bundled in the EMFT
Emfatic component. Gymnast Generator was used to generate a large portion of
Emfatic, as a step forward towards combining parser generators with modeling
in a symbiotic way.
3) Finally, I would appreciate if you add the Emfatic team (Miguel Garcia,
Chris Daly) to the list of interested parties for TMF.
Regards,
Miguel

Hi Miguel,
thanks for the feedback, and sorry for having such an incomplete mention
of Emfatic/Gymnast. Is there some kind of documentation about Gymnast?
We'll update the proposal ASAP.
thanks,
Sven

Let me first try to understand the relative positions of Gymnast and TCS.
If I am not mistaken correctly, Gymnast generates a metamodel from a
grammar. It is possible to follow this approach with TMF using
TMF/xText. I will let you (Miguel and Sven) tell me more about the
details ;-).
TMF can also start from a metamodel. TMF/TCS lets you specify the
information necessary to create a grammar that is not already in the
metamodel. Can Gymnast do that as well?
I am surprised that you do not mention TCS in your bibliography.
Also, do you have a list of syntax constructions supported by Gymnast?
For instance, can you have operators and expressions, does the generated
metamodel define a tree or can it also define a graph (e.g., attaching
variable usage to definition/declaration)?
Best regards,
Frédéric Jouault
