                 Key: SCXML-116
                 URL: https://issues.apache.org/jira/browse/SCXML-116
             Project: Commons SCXML
          Issue Type: New Feature
         Environment: Eclipse plunge-in,GMF,Commons SCXML
            Reporter: Gui Xunlong


I have been using Apache Commons SCXML Engine for more than two years,Now i have an idea to
improve it, and I wanted to post it and see if there would be any interest in it in the Apache
SCXML community. If possible, i want to hold it as a GSoC(url:http://socghop.appspot.com/)
open source project.

The basic idea of the project is to create a Eclipse based visual editor and debugger for
SCXML which can also generate SCXML statechart to Java code.
 
State Chart XML (SCXML) is currently a Working Draft published by the World Wide Web Consortium
(W3C). SCXML provides a generic state-machine based execution environment based on Harel State
Tables. SCXML is a candidate for the control language within multiple markup languages coming
out of the W3C.It is very useful to handler complex status transfer logic,but if a SCXML file
is really so huge and complex,it will become too difficult to maintain and refactor or to
test its logic validity.
 
This project is to develop a Eclipse plunge-in visual editor which is capable of showing a
graphical representation of the process model and allows for adding breakpoints to activities,
variable modifications and managing the debugging process for SCXML.I have already done some
work on both SCXML and Eclipse GMF,even i tried to implement a SCXML editor using GMF and
got a little achievement,so i want to develop this editor with GMF and have enough confidence
to finish it.
Usually,State Chart XML file will be running on a SCXML engine(for example, our Apache Commons
SCXML),if some one only want to achieve the SCXML file's business logic,but do not want to
or can not use some SCXML engine due to licence problem etc,this tool can export SCXML file's
logic to executeable Java code which has the same state logic translation with the SCXML file.
 
This is my mainly idea,if anyone has any questions or comments, or would be interested in
mentoring this project, please let me know. Thanks.
