I spent a lot of time googling, now I'll try it here. Some of you might know the "regions" available in Microsoft Visual Studio, which allow you to collaps an arbitrary part of your code to just a single line, more or less like
// [start] The text which will appear instead of the collapsed part
...
A bunch of lines of code
...
// [end]
In my opinion this is a really fine way to comment code, but it doesn't seem to be available for Java and Eclipse. However, there was a plugin for that ( click ) but it doesn't work with Eclipse Helios.
So here's my question: Do you know a way to achieve this kind of code folding in a current version of eclipse?
You can try this one - http://incubator.apache.org/isis/ide-support.html
It claims to be working on Eclipse 3.5, so there is a chance it will work on 3.6/3.7 (you will have to try).
Hope that helps!

I am developer who is using xTend. The docs for this kind of programming language are introduced at this link:
https://www.eclipse.org/xtend/documentation/
When I used Eclipse Photon version to develop my product. I ran into the issue related to debugging.
AFAIK, xTend code will always be intermediately compiled to java code first.
The issue description as below:
The debugger can hit breakpoints if they are toggled in java code.
But, when I toggle breakpoints in xTend code, the debugger doesn't hit the breakpoints any longer.
I tried some times to refresh my Eclipse workspace (delete old one / create new one), even used other version of Eclipse. But, still didn't solve the issue.
Who had already run into this situation, could you share your idea or solution on this ?
I have resolved the problem.
This happened because the configuration not adequate.
If you have same situation to me,
please consider to check all below Eclipse debugger's configurations.
When I copy/paste by Ctrl+C/Ctrl+V or typing code, my eclipse quite delay 3-4s to handle. Sometimes, it caused that my CPU has loaded 100%. I really need adivices for this issue.
it's maybe be a bit late for OP but i've experienced same behavior when using CTRL+C/CTRL+V (and CTRL+Space)
i've seen that ctlr may be used to perform hyperlinking. Then i mapped the hyperlinking modifier key to ALT (General-> Editors-> Text Editors -> Hyperlinking) and eclipse is not lagging anymore when i try using CTRL+C/CTRL+V
It is problem only in Eclipse? It is only sometimes or allways? Can be caused by other proces running like antivirus etc? Wich one eclipse are you using? Did you tried other version of eclipse? Im using Photon, after start up its take few sec to load stuff using ctrl+space bar, but after first one is ok.
I just discovered that my NetBeans suddenly stops importing classes that are found in the Java API but can still import classes from my external libraries. Take a look at the image below:
As you can see, List and ArrayList are classes from the java.util package but the usual suggestions for importing them are not shown here, instead it is asking me to create class. I know that I can type import java.util.List; on the top of the code but life was better before! Please I need help thanks.
I had the same problem a couple minutes ago... Terrible. The same problem has been reported here:
Bug 235712
The solution which I've found there was sufficient - simply delete the Netbeans cache...
In order to do this, go to Help ==> About . Then go to the directory with cache and delete all you find in the "index" catalog.
After restarting the NB, everything was cool.
Today I came across the same problem. It happens that it actually is very easy to exclude a class from code completion if you click in the wrong place while working.
To solve it (netbeans 8.2) go to
Tools - Options -> Editor tab
Then select Code Completion Tab
In the drop Down select JAVA (in my case it was Java)
You will find a box bellow titled Package/Classes
In the EXCLUDE tab you probably will find the packages marked to be excluded from code completion. Just remove the ones you want back.
Check under Preferences->Editor->Code Completion to make sure auto complete is on, though by your screen shot I assume that it is.
Also try Preferences->Editor->Formatting and set your Language to Java
In my case, NetBeans was refusing to suggest Scanner. As it turned out, all I had to do was remove java.util.Scanner from Options » Editor » Code Completion » Packages/classes: » Exclude. Then the autocompletion for Scanner returned.
I have been wracking my brain trying to figure this out. For the first time I used jEdit the other day and I was pleasantly surprised that it auto indented my code (meaning that I'd put in the following code:
int method () {
_ //<-- and it put me here automatically
I've tried to get the same thing working with eclipse but with no success. I got into the code formatter but I don't see how to make that happen.
Is it possible to do this? Also while I'm here, is there a such thing as a eclipse plugin that will allow you to search the methods and classes of the standard java library?
Thanks
Personally all I use for this is the format options Window->preferences under Java->Code Style ->Formatter.
I once took the time to tweek how I like my code to look like when I work and exported the whole thing. After that I just code without too much bother on what it looks like. When I find the code looks messy by pressing the combination ctrl+shift+f and the whole class becomes pretty again, comments and all.
After a while it pretty much became a reflex...
code code code
ctrl-s, ctrl-b (cause I disable auto build sometimes), ctrl-shift-f
code some more etc...
Once I got used to this I never really cared how it presented the code as i was typing because I knew it would look all pretty as soon as the loop/if/switch/method etc is finished
My clean eclipse install does this by default.
Have you changed any options? Make sure the file you are editing has the .java file extension. The preference options that control the typing automations are under Java -> Editor -> Typing in the Window -> Preferences menu.
Also, I find that the auto-indenting, and most of the other auto-complete functions of eclipse do not function well if the file I am editing has errors in it which prevent compilation. Make sure that your curly-braces are matched correctly, this is the main one that I've noticed blocks auto-indent.
Regarding searching through the standard Java libraries, use the Search -> Java.. menu option, and check the JRE libraries checkbox, then search away. You can also use the Hierarchy view to see how the classes relate. Also, in the Package and Project views you can expand the JRE System Library, and then expand rt.jar which holds pretty much all the standard Java pacakges.
Eclipse has always done this for me by default.
One really cool thing about eclipse is that you can search preference pages. Just right click and go to prefrences. Go to the "Window" menu, and click "Prefrences". Then at the top of the tree view there's a text box that says "type filter text". Replace that with "indent" and it should bring up the page where the indent option is.
Make sure that eclipse recognizes your file as a java file, that you're using the Java distribution, the latest version, etc.
Iv been trying to work around the eclipse indenting and other supposed features for years, and it seems that the bottom line is this ...
It only works for the programming style of the authors, so to use it you need to modify your style to comply.
This would be OK except that the authors of eclipse have some very strange ideas about common shortcut keys.
One horrid example is the search features, eg when did Ctrl+K become "Find Next occurrence" and why doesnt F3 or n work?
That all being said I use eclipse because if you have the time to wait around while it starts up - or never close it - and you can modify everything youve learned about using an editor - why why why - then it will certainly increase your efficiency.
Please note that there is a preference setting for indenting, it can be set for a project, a workspace, or globally, but no matter how you set it eclipse will still chuck tab characters in where you dont want them.
In fact its indent crazy, like it wants to indent everything, even if its already indented.
Like I said Iv been using it for years and it STILL drives me nuts with its random behavior.
Follow these steps for Eclipse:
Select all text: ctrl+A
Correct indentation: ctrl+I

I'm looking at learning JavaFX.
I've tried setting Eclipse to develop a small app and I've downloaded the Eclipse plugin.
Eclipse JavaFX plugin
BUT... it just seems, well, flakey.
So I have 3 questions...
1: Is there a better plugin?
2: Or is there some great set of tutorials out there that I'm missing?
3: finally, is it meant to be easy to call Java code from FX? I'm stuggling, it there a good example somewhere?
On questions 1 & 2, Eclipse underlines code in red that just shouln't be. For example..
see this image... alt text http://www.qenet.co.uk/fx.jpg
Why does it underline bit of imports in red?
I know this is little of an open ended question. So I guess my main question is this...
Is my experiance of JavaFX and Eclipse the best I can hope for? Or am I missing something ?
(and I'm not looking for a Yes/No response) :-)
Just looking for a discussion on how best to learn/develop JavaFx.
This kind of thing is not unusual. A lot of Eclipse plugin editors have problems dealing with error tags and the like. For example,
I find that the XML and HTML file editors often fail to clear error and warning markers, and the only way to get rid of the markers it is close and reopen the file.
Even the Java viewer gets it wrong in some circumstances, though the problem goes away when the relevant files are saved.
When you update a spelling dictionary, the spelling checker is not rerun and the spelling error markers are not updated. In fact, you have to restart Eclipse for this to happen.
I suggest that you try saving files, and closing/reopening editors to see if that makes the bogus error markers go away. Then decide whether Eclipse is the right IDE for this task.
I've never used NetBeans (at all), but you would expect that it would do a better job supporting JavaFX. After all NetBeans and JavaFX are both high profile Sun products at the moment.
Netbeans is really the only way to go at the moment for JavaFX development. They are both Sun products and Sun has made sure the two work very well together. Before long Eclipse and others will catch up but for the moment that's how it is.
There is another JavaFX plug-in for Eclipse from Exadel. You can download it here: http://exadel.org/javafxplugin. Give it a try.
I have similar problems but funnily only under Linux, not Windows. Hope they change that soon.
To me this has happened when I wronlgy installed javafx sdk 1.2.3....This plugin works only with 1.2.1... :/
