Is it possible to write a Google Wave plugin that turns it into an IDE for programming? With such an extension, Google Wave would be a replacement for Eclipse etc., and it would naturally be a code repository at the same time (replacing SVN, git, etc.).
Users (programmers) would be able to create code files directly in Wave and add collaborators to do pair programming etc. The whole codebase would live in a Wave folder, and an extension would do the building and compiling on the fly.
How would one go about writing such an extension?
Have you looked at the CodeRun IDE? Except for the collaboration aspect of google wave, or coding non-web apps, this might be ideal.
I expect coderun will become more collaborative as time goes on.
I like the idea and to be honest had thought of something similar myself. Stability and speed of Google Wave are valid points of course.
I see this being built over the Wave protocol than over Wave. I mean strip out some of the features of the Google Wave product but keep the underlying principles of Waves and collaboration.
i definitely would want google to get an IDE, they have mostly everything already:
- Appengine
- Appengine SDK
- GWT
- Google code
- Google apps (docs, talk, mail, sites)
They just need to put it all together in a single IDE and make it online based (webapp) with offline capabilities, maybe HTML5 or gears so you can use it no matter the browser or OS you use. Then this IDE connects to all the online tools mentioned before and you just have to write, junit test, run test, make some how-to's and wikis and commit. CodeRun is a good starter.
This is one of the first things which popped into my head when I recently watched the presentations from Google IO, and for Wave in particular. The demonstration of collaborating on the Sudoku app is a good example. The ability to replay conversations was particularly interesting and has obvious uses in developing as a team.

I am seeking a way to allow my non-tech users to specify a workflow and execute it (if anyone is interested, I want them to specify and execute test cases). Visual programming seems a good way to go.
Can I modify the Scratch IDE to remove some categories (such as sound, motion, etc), and add some of my own? Ditto for individual keywords (obviously, I then need to handle new keywords).
I have Googled, but the answer is not immediately apparent.
[Update] I have just found Google's Blockly
Blockly was influenced by App Inventor, which in turn was influenced
by Scratch, which in turn was influenced by StarLogo.
It looks very promising. Especially when it says
Exportable code. Users can extract their programs as JavaScript, Python, PHP, Dart or other language so that when they outgrow Blockly
they can keep learning.
Open source. Everything about Blockly is open: you can fork it, hack it, and use it in your own websites.
Extensible. Make Blockly fit with your application by adding custom blocks for your API and remove unneeded blocks and
functionality.
One possible snag is that it is browser based, but if my management don't like that, then I can create a dummy Windows based app consisting of little but a TWebBrowser component.
I will investigate and report back - unless someone else posts an acceptable answer first.
The short answer to your initial question is: no. You can't customize Scratch, or not to the extent that you seem to ask/want.
That said, look at:
custom blocks.
scratch extensions.
variants like snap
using scratch's source code in squeak to make your own variant.
other systems inspired from scratch, like appinventor and blockly.
Only the first two are compatible with the scratch web site.
A word on the site: depending on your purpose with Scratch, the exchange between users is a powerful part of scratch. Check how cooperation is supported, like the backpack. There's also a good wiki that documents much of the above.
I'm planning on making an online game using GWT (HTLM5/JavaScript) and Google Compute Engine for server. I used to make a turn-based game using AppEngine (servlets) and that worked fine. Is there a way (plugins etc) I can develop a Compute Engine project within Eclipse? Or what would be the best work flow in this case. Cloud9 seems interesting but, I'm not sure how does it integrate with an GWT/Eclipse project....
My aim is to make developing and debugging client/server stuff as fluent as possible, so other ideas are welcome too :)
Have a look at the documentation page. Based on the info there, it seems to suit your needs.
What is the best practise for developing a lite app and a full app with additional features? It is better to create 2 projects in eclipse oder just one project with e.g a constant for switching the functionality? I think there are advantages and disadvantages for both approaches: With 2 projects you always have to do everything twice if you update your apps, with only one project the app is larger then needed.
I didn't find much about this topic, so I ask you, what is your approach or do you know some articles explaining solutions?
At least, I found this:
http://blog.donnfelker.com/2010/08/05/howto-android-full-and-lite-versions/
Any more approaches/ideas ?
Thanks.
I'm not familiar with the specifics of Android development, but in general I would move all the real code to one or more library projects and then reference that from specific projects that can take a "pick-and-mix" to assemble differently capabable applciations.
Taking that a step further component technologies like OSGi allow you to pull together arbitrary selections of components as specified in a configuration file.
At the moment Iam evaluating java web frameworks. More precisely Iam talking about GWT, JSF2 and apache wicket. One very importent criteria in this evaluation is prototyping.
The prototyping process in my company can be described by the folloing:
The customer can produce GUIs with an easy to use WYSIWYG editor, by drag&drop-ing web components on the corporate predefined website structur. There is also a need for some litte dynamic being like navigation from one frame to another.
So Iam looking for tools. These tools should not only provide nice GUIs but also deliver
some basic code, which can be forwarded to the development. The aim is to avoid missunderstandings between designers and developers as much as possible. More or less the
developers just have to implements the code, but not to implement the optical requirements.
In addition it would be desirable to customize the components thats been used in the WYSIWYG editor. Does anyone know any good tools for the mentioned frameworks (GWT, JSF2, wicket)?
One of the challenges with WYSIWYG tools for UI is that you generally have to pick between rapid prototyping and maintainable code. Even then, as soon as you want to do something that's not supported by the prototyping tool, you can implement it as you would without the prototyping tool, but your round-trip functionality (namely turning your app back into something that can be edited) is broken or crippled unless extra work is done to generate the metadata that the editor needs.
Upgrading between major releases is another issue. Vendors and groups who have developed these tools have a historically spotty record of when they stop supporting older versions, reasonably because of limited resources and sometimes difficult problems with how to track solid innovation happening in the framework itself.
My suggestion instead is to prototype with an RIA prototyping tool like Balsamiq Mockups or use a grid system like 960 Grid to generate rapid prototypes, then use a web development framework that allows your developers to run the code with or without the backend server. Wicket has a tag called that is great for this kind of thing -- web devs can fill a div with stuff that a component should generate, and Wicket devs can wrap the contents of that tag with after they implement it. Both parties can coexist for a long time that way.
Try GWT Designer for GWT.

There's nothing like this for Wicket that I know of. The closest you would get to any kind of resource reuse from your customer would be to give them a drag and drop HTML editor - the resulting HTML could then form the basis of Wicket page/panel layout.
if you are planing to use a javascript library, you may use extjs,

they have developed a nice designer

there is also a port of ext in GWT

You have to pay for a commercial license if your application isn't open source!
I am about to start on a college project (a web application) and I have never used a full-fledged IDE such as Eclipse.
Turbo C/C++, Visual Basic 6,Java Basic, a bit of SQL, ASP, etc is the sort of exposure I have.
What things should I keep in mind before starting my project using Eclipse? Are the tools mentioned appropriate for the project?(If not please give a detailed answer)
Designing - UML (Rational Rose)
Language - Google Web Toolkit
Server - Google App Engine
IDE - Eclipse
Version Control - Subversion or Mercurial?
I would definitely recommend Googling first. There are a number of tutorials regarding Eclipse as it is a very popular IDE. A quick Google search of my own brought up all these results: developing web applications in eclipse
As for other things to consider, if you are developing a web application, you'll need:
web server (Tomcat is a popular one)
possibly a database (MySQL is an open source, easy to use DB)
language (I'm assuming you're going with Java since you are using Eclipse)
Of course, you'll also need to consider how you hook everything together and what technologies you want to use to do that. (Hibernate, Spring, etc) Eclipse itself has a ton of plugins to help bring together all these various aspects.
That list from Wikipedia is a good and comprehensive list, but if you are learning or developing on your own machine, you may not necessarily need all of that.
Hope that helps.
Since it is a web application, then start with the looks of it.
First, layout a template of how your pages should look, that is what users see. If it does not look good, the users will think the application (in its entirety) is also not good (it does not matter if the code behind the view is perfect; it will just make a first bad impression).
Start with that and be consistent with the design in all your pages. SiteMesh is a nice tool to dissociate the looks of the page from the functionality you put in it.
Then think what the application will do and what it will use:
you have a database? (use something like MySQL). With what are you going to access it? (IBatis is nice; Hibernate I think is a bit heavy weight for a first project)
you need a server: Tomcat is easy to use;
are you going for a simple Servlet/JSP approach or you want to use a framework (look at Spring or Struts);
try to find the good ways of writing the application, look at service layers, DAO pattern, DTO, MVC. Also, you must understand how HTTP works.
A lot more could be said.
Ah.. and also use a source repository. It’s a must (even if you work alone on this project).
Eclipse can handle all of these tools, but then so can Netbeans.
For your first project with GWT you should read through this tutorial:
http://code.google.com/webtoolkit/tutorials/1.6/gettingstarted.html
If you don't know Java then you will have some learning to do, and unlike Visual Studio your UI won't be just drag and drop, so it will be a bit harder than you are used to.
Subversion is fine, it is a nice source control, and any IDE will work with it.
Depending on your project would determine if GWT is the best choice though.
I expect UML may be overkill, and if you were following an agile methodology you wouldn't use it.
Your best bet is to get the UI done first, just have it appear as you want, and have some fake results, until you are happy with the look and feel.
Then, start to do the wiring to whatever you need on the backend.
Don't mean to be harping on you, but is Eclipse a must? For myself, in the beginning NetBeans turned out to be a really painless introduction to getting a web project up a running fast. I believe in the beginning one will spend a lot less time fighting the IDE with NetBeans.
A lot of the items from your bullet list NB makes super easy to ramp up as well. Just my $0.2
