Re: [ease-dev] [GSoC Proposal] Support generic script keywords

[Vidura Mudalige <vbmudalige@xxxxxxxxx>]

Hello,

I'm Vidura Mudalige, final year Computer Science and Engineering undergraduate of university of Moratuwa, Sri Lanka. I'm very much interested in working with EASE in GSoC 2016.

I am interested in project idea 'Support generic script keywords' and looking forward to contribute. I have worked with EASE in GSoC 2015 as well. Therefore I am already familiar with EASE development environment and the contributor workflow. In addition to that I have a good experience with EASE as a user as well. Specially I have used the charting module for most of my projects.

I would like to know more details about this project idea and expected deliverable. Also I need to learn about the event bus. Currently I am following Eclipse 4 event system (EventAdmin) - Tutorial[1].

Thank you.

This is a proposal for GSoC 2016, to add generic script keywords to EASE.

EASE allows to register script locations. Such scripts get their own Explorer view and typically hold macros that users need on a daily basis. Such scripts are simple scripts files, augmented with a special comment header, that may contain keywords. When a script location is parsed, the keywords are extracted and actions are performed upon them. Currently we use a publisher/subscriber pattern to push these keywords to interested listeners which then implement actions. As of today we support actions to bind scripts to toolbars and menus.

In the future we want to support generic keywords and provide a simple way to listen for them. The idea is to use the event bus of Eclipse instead of the publisher/subscriber pattern. So new scripts will promote their keywords on the event bus. Clients may listen for such events and react on them accordingly.
want to add some security to them.

Your task would be to change the current implementation to use the event bus. Therefore you need to change the current listener mechanism so that existing functionality does not break.
Further we need a page in the Properties view to display and change script keywords without touching the script file content.
Finally a new keyword handler should be implemented that allows scripts to be run on certain timed events, like a cron job. The cron syntax [1] should be supported. Furthermore the special entries @Startup, @Shutdown should be supported.

Skills required for this task:
You should have experience in UI programming best already with e4.
Experience with the event bus will help you in solving this GSoC assignment
and of course you need to get acquainted to EASE.

If you think of applying for this task you should introduce yourself on this mailing list. Further you should do a sample commit to EASE. This could be a small donation to a JavaDoc comment in one of the source files, so you do not need to fix code already. It will prove that you are able to set up your development environment and that you are familiar with the contributor workflow.

looking forward for your applications
cheers
Christian
