Subject Re: Re: [SCXML]Eclipse plunge-in based visual editor,debugger and codegeneration tool for SCXML
Date Sat, 03 Apr 2010 13:00:11 GMT

Hi Rahul,
Thank you for your advises, i have modified my proposal both in the GSOC system and the wiki,
you can find it here:
http://wiki.apache.org/commons/SCXML/GSoC2010EclipsePluginProposal 
In fact, i am eager to find a mentor for this project, you are a Commons SCXML commiter, can
you recommend  some other Commons SCXML developers for me ? Or, if possible, can you give
me some Commons SCXML commiters' email, i will try to contact with them to check if they are
interested. Thank you!

OK, thanks, I've renamed it to the following which is more descriptive:
  http://wiki.apache.org/commons/SCXML/GSoC2010EclipsePluginProposal
I see that you have also added your proposals (2) to the GSoC site.
Finding a mentor will increase your chances, but looks like we don't
have one as of now. Inspite of that, if you are interested in
feedback, I have two comments:
 * In the ordered list at the end of the "Detailed Description"
section, I think it may be better to switch the order of items 2 and 3
(I think the export feature to generate an SCXML document is lower
hanging fruit, and is also a more requested feature than the debug).
 * In the same list, I see that you mention item 4 as a "tentative",
and I agree that it really seems like a stretch goal. Perhaps you can
reduce the number of code generation deliverables (say, just leave
Java) and even that code can leverage the Commons SCXML APIs and
assume those jars are available (unlike your scenario in the paragraph
above the list where you talk about generating code without
dependencies).
