Subject Re: Re: [SCXML]Eclipse plunge-in based visual editor,debugger and codegeneration tool for SCXML
Date Fri, 02 Apr 2010 15:58:46 GMT
Hi,

In fact, i have finish a GMF based State Chart editor in my past research job, but it is simple,
do not have debug function and can not generation code, now ,i want to extend it as a full-blown
visual editor for GMF. Even before i developered my SCXML editor,i did some survey jobs,including
UML2Tool and Topcased.

UML2Tools is a GMF based UML graphical editor, i do not think it is suitable for SCXML,absolutely,
UML and SCXML have different data model.
Topcased is more powful, it is a UML 2 editor,SysML editor and more,and may be i can build
a SCXML editor base on it, but i do not think it is  easy. I am familiar with GMF, build EMF
data model, i can build a GMF SCXML editor demo very fast, but if i use Topcased, i think
it will take more time.

The most important point is that these editors do not supply debug function, and can not convert
 SXML to Java,C++,JavaScript or Python code. Also, what the SCXML community need is a pure
SCXML editor,i think framework like Topcased is to heavyweight. Now, i have a simple GMF based
SCXML editor already,why i do not extend it as a more powful SCXML editor and give it some
more cool function support ?

Hi,
Cool project idea. I have a concern though. I believe there are a few free
and open source Eclipse-based graphical statechart editors already in
existence, including Eclipse UML2Tools[0] and Topcased[1]. Additionally,
UML2Tools is based on the GMF stack. I was wondering if you could explain
the relationship of your intended graphical Statechart editor to these
projects. In particular, could you explain: 1) how these existing editors
fall short of providing a satisfactory solution, and b) why it is better to
develop a new GMF-based editor from scratch, as opposed to trying to improve
these existing editors?
Thanks,
Jake
