Hi everyone,
I'm a french Eclipse user and developer. I'm working on several Eclipse plugins projects for my job and I'm maintaining a blog to spread knowledge about RCP platform and related tools : developpef.blogspot.com
I would like to get involved in some community project, especially Code Recommenders that I found really stuning.
Please let me know how can I get involved and for what.
Regards.

that sounds great!

In fact there is a lot of work in many different areas. For some areas
it may take quite some time to familiarize yourself with code and
concepts but there are also some areas which could serve as a good entry
point to Code Recommenders.
Did you follow the "Fulltext Autocompletion proposal" thread in this
forum? There are quite some people (even from the JDT team) that would
like to see such a completion engine for Eclipse.
We created a simple completion engine that works on regular expressions
so far. But there are quite a lot of things we could/should implement.
For instance,
* ranking these proposal according to some notion of similarity,
* highlighting chars in the proposal that matched the regular expression,
* extending the concepts to support completion on arbitrary proposals
etc. Since this engine starts on the "green-field" this could be a good
way to start contributing since you have to deal mostly with extending
JDT but don't need to get into the details of Code Recommenders' core
from the beginning.
For sure there are many more ways to contribute like reporting errors,
improving user documentation in the Eclipse Wiki, writing cheat sheets
that show Code Recommenders in action etc. You may also keep your eyes
open for new ideas how Eclipse could be improved and discuss them here.
Many more things are possible.
Is there an Eclipse Indigo Democamp close to your home? You may consider
to present Code Recommenders there? ;)
Let us know what kind of work interests you.
Cheers,
Marcel

Hello Marcel,
Thank you for your answer.
I took a look at Demo Camps planned for this year and saw there is one coming on june 22nd at Toulouse, right in my town!  Should consider taking a tour out there...
As you mentioned, starting reading and writing for Fulltext completion proposal may be a good entry point. I'm very curious about how to contribute to this first "sub-project".
After many researches, I could not find many documents on how to concretely get involved and start coding for a project. Maybe you could help me?

Hi Paul-Emmanuel,

Definitely! If you like to present, I'll share my (5 introductory) demo camp slides. But even if not: Visiting demo camps is always worth doing

You mean a general guide "How to Contribute"? Or a specific one for Code Recommenders?
I couldn't find any good (general) documentation on this too. Thus, I added a small wiki page on this here. Can you read it and provide me with some feedback whether this is what you were looking for - or what is missing?
In the case you are looking for a project specific guidance. So far we have:
http://wiki.eclipse.org/Recommenders/ContributorsWanted and http://wiki.eclipse.org/Recommenders/ContributorTopics
I'm currently rewriting the former to match the Code Recommenders specific parts. But in a nutshell it should roughly work like this:
# Check out our git repository.
# Create a feature branch.
# Make your changes
# Commit them locally.
# Create a patch, and finally
# Submit your patch to Bugzilla.
This is typically done quiet frequently with little patches (less than 200 lines) but takes longer if the patches get larger since patches containing more than 200 lines require an IP check from Eclipse IP team. If you want to learn more about this just check out http://www.eclipse.org/legal/EclipseLegalProcessPoster.pdf

Hi,
As you mentioned it, Eclipse Legal Process Poster is the only "interesting" official document I found. By the way, your links look great and explain clearly what I was looking for as "first of all information". For the moment, I only have one question to add : is there another way (I mean other than this public forum) to contact project leader/responsible in order, for example, to get involved? The project's home page presents team but nothing like emails...
Your page on Contributor topics is a good simple way to understand where project needs help and to pick up the prefered one to get started.
So, when could I start?? What has to be checked out as project source : the git repo or some other svn? Maybe it is what you are writing about... Please keep me aware, I'm now very excited to start helping you guys!
Cheers
[Edit]
I checked out source from git in order to have a first look at the existing code, and the first thing I stumbled upon is that you are using Tycho? So great! I had to make it work for some projects in my job so I study it but could not succeed in integrating it in our workflows because of 0.9 version's limitations. I wrote a serie of tutorial articles on my blog in order to spread knowledge Hope this will help!

Thank you for all these details. I will start installing and running all of those as soon as I can and keep you in touch within a day.
Don't worry I already used the tools you mentioned, except Git, but this is the game, learn and work at the same time!

Hello Marcel,
I am up and running! I successfully configured my dev environment and tested subword completion. Seems already quiet interesting!
I am now waiting for some more information from you about what could I do.
One question by the way : do/will I have a commiter id for git? For the moment, I cloned from the anonymous URI but don't know if I could commit when required.
Regards

Hi.
Why not feature one. Could be interesting. But I think I need more details : completion should make proposals also for class names and static members for example?
I will start digging in the code as soon as I can.
I would really appreciate taking lead on this feature, even if I don't know if I am truly capable of... I'm still a newbie in Eclipse processes! So I try reading and learning about all of this, but when I will be ready to show you some snippets (no too soon of course!), I may still have some more questions on how to submit it to you and so on...
So I hope I wont take you too much time, and please forgive me by advance!
Keep you in touch on what I am doing for the newt few days.
Thanks again.

Hello,
I started implementing a solution for subwords completion proposals (without having to copy the whole logic of org.eclipse.jdt.ui.text.java.CompletionProposalCollector.createJavaCompletionProposal(CompletionProposal) as you mentioned it).
Here is what I did :
- In SubwordsCompletionRequestor I call org.eclipse.jdt.ui.text.java.CompletionProposalCollector.createJavaCompletionProposal(CompletionProposal proposal) in order to get back the proper proposal, letting jdt make its job.
- In SubwordsCompletionRequestor I call a newly created SubwordsCompletionProposalDecorator that is used to decorate jdt proposal with our new isPrefix() implementation.
- Decorator instanciates all "Subwords proposals" extending jdt proposals with their own properties.
- And of course I made the decorator managing all proposal kinds returned by jdt collector.
After some tests, I think it is quite what we were looking for. So far, how can I provide you my snippets (in order to get your review)?
Cheers

Hi Paul-Emmanuel,
this sounds great - but #isPrefix was originally a protected method I made public for testing. AFAIK this method is called from "this" only. Could you verify that completion also works when you trigger completion after typing, say, just one character and then continue typing and verify that the proposals are refined?

Hi Marcel,
I did some more tests and I can confirm that completion is still refined when typing or using left/right arrow keys. Also, isPrefix() is still protected, as overriding jdt completion proposal types method (so far, RegexMatcherTest does not compile anymore, but I may fix it later).
I drew you a simple class diagram trying to explain my implementation choices.
I also join two screenshots of running completion.
Please keep me informed if I missed something.

Hey Paul-Emmanuel,
that sounds good. Could you create a new bug report and attach your changes as patch (e.g., by using git-format-patch)? Then we can download and test your patch.
I'm looking forward to it!
Thanks,
Marcel
