Likes and dislikes about Eclipse E4
Update 2009-08-22: discovered Java2Script, added an item about it below.
E4 is the next generation of the Eclipse Rich Client Platform and brings numerous improvements in a bid to stay relevant as a platform. In this post, I’ll first summarize what I have already written on E4 and then make several suggestions as to where I think E4 should be heading. It is an extended version of a comment I added to the artice “Eclipse has a future” which explains what E4 is and how it improves on prior versions. The author finishes with the sentence “I really am psyched!” (regarding Eclipse’s future). I share that excitement, especially after I found out that Eclipse is looking at all kinds of technologies (RAP, Flex, Dojo) for web-enablement.
What happened so far
First, a recap of what I’ve already blogged about E4 (directly or indirectly), listed in chronological order:
Next, I’ll mention the main things I would tell the Eclipse team were I ever to communicate with them directly. Due to developing Hyena
, I have experience with the following platforms: Dojo, GWT, Eclipse RCP, jQuery. This puts my in a good position to judge were Eclipse wants to go.
- Browser widgets: Not enough standard widgets is another GWT problem. If GWT had the Eclipse community behind it, I’d suspect that that would quickly change.
- GUI layout: For SWT browser edition, the thing to watch out for is GUI layout. It is what bothers me most when using GWT. Help is on the way, until then, drawing to Canvas (like Bespin does) is intriguing. Unfortunately, MS Internet Explorer does not support Canvas, yet.
- More GWT wishes: More of my unfulfilled GWT wishes and a brief overview of 2.0 are posted here.
- Java2Script: looks like an interesting alternative to GWT that is already Eclipse-based. I’m not too fond of how the widgets look (especially on Mac OS X Firefox). But the technology is sound and the widgets can (and probably should) be replaced by a standard widget toolkit such as Dojo.
- RAP (a server-based technology that makes it relatively easy to add a web interface to an SWT application) is technically impressive. But the resulting applications are a bit slow, there is a limit of running only one application per browser and server at the same time, and you cannot do browser-only things like offline applications. As you can already guess, I would like E4 to focus on browser-centric technologies like GWT and Bespin and not on server-centric technologies like RAP.
