e4 - Eclipse 4.0 : First Impression

Looks a bit funny

Off is On and On is Off - I saw that Build Automatically was Off so I switched it On, and then my code changes had no effect... few minutes later I realized that if something is turned Off in the UI, it may mean that it is actually turned On! e.g.Mark Occurrences, Build Automatically.  Or in the case of 'Edit > Smart Insert Mode' I cannot even toggle it.

Layout and minimized Views - I like the overall layout and the fact that I can put views in the editor area. I also like the way when minimized views are selected they open in a pop-up sort of a way. Overall the UI/layout feels nice.

Custom Key Bindings - mmh...

Order of menu and toolbar items - The ordering of items in menus and toolbars can be a bit different from 3.x versions. e.g. navigate menu, run/debug toolbar

I can use it for my daily work, except for some minor glitches and some funny behavior I have been able to use it for last few days. And I do like the layout, mixing of editors and views, and the overall feel of the UI to not go back to 3.x (at least for now).

New Command in JDT : Open from Clipboard

This is what I used to end up doing very frequently
- copy something like String#getBytes from a bug comment
- press Ctrl+Shift+T in Eclipse
- paste the copied text Open Type dialog
- argh... no matches
- delete the method name
- open the type in an editor
- press Ctrl+O
- argh.. what was that method again?
- go back to bugzilla and read/copy the method name
- come back to Quick Outline and filter the method
- and finally reach the method

The new command opens a Java element or a Java stack trace from clipboard. If the clipboard content spans multiple lines then the it is pasted to the Java Stack Trace Console. If the clipboard content is a single line the command tries to open the matching Java element in an editor. Some examples

• java.lang.String
• String#getBytes
• java.lang.String.getBytes(String, int[], int)
• String.java:123
• at java.lang.String.matches(String.java:1550)
• java.lang.String.valueOf(char) line: 1456  

I use this command with a key binding of Ctrl+Shift+V. After doing a Ctrl+C the most natural thing to do is Ctrl+V so the key binding for this command should be similar. Plus Ctrl+Shift+V is also similar to Ctrl+Shift+T and Ctrl+Shift+R, making it a bit easier for me to remember it.

This command (Bug 48880) is already in nightly builds and will be in the today's I-build.

As a final note I should also mention 2 'nasty' Platform bugs that I faced while implementing this command

• Bug 324160: [Commands] Platform should support to use the action IDs from the action set contribution in menuContribution
• Bug 324161: menu contributions added using 'endof' should appear before contributions added using 'after'

I say nasty because in its current form the whole menu contribution, command, actionSet, action story can be very confusing...
