Fuzzy auto complete in Eclipse - eclipse

Few days ago, I download a new version of Eclipse(4.4.2), and found a new feature on that, is fuzzy auto complete (as the bottom picture in screenshot below).
When I switch to another workspace, this feature has gone, it only allow prefix to auto complete (as the top picture in screenshot).
Did any one know where is this feature's setting in eclipse?

After i half delete/half reserve file in .metadata directory, I found this feature setting in Eclipse finally. Open Preferences dialog, navigate to Code Recommenders->Completions, check the option [Enable intelligent code completion] and [Subwords-Completion Processor].

Netbeans 8.2 wont apply themes

For some reason, Netbeans IDE 8.2 won't apply any different themes than the original one. Has anyone else had an issue with this? I have applied the new theme and restarted the application many times without success. Thank you.
It's very hard to identify what is wrong since everything in your screenshot looks perfect, and Sublime-Theme works for me using NetBeans 8.2 on Windows 10. See the file with the tab NewServlet.java in the screen shot below.
Note that using Sublime-Theme does not impact everything. For example, the Projects and Navigator panels don't change. Since your screen shot only showed the Options window, and the Start Page doesn't change in the editor either, are you absolutely certain that none of your files in the editor are using Sublime-Theme?
Also, you say that "Netbeans IDE 8.2 won't apply any different themes than the original one", but NetBeans comes bundled with several themes, such as NetBeans and NetBeans 5.5 as shown in the screen shot below. How many options are shown in the profile drop list for you? If you select a different theme from the Profile list and click Apply the rendering of your files in the editor should change immediately. Is that happening?
If so, the problem is probably confined to the installation of Sublime-Theme. Try deleting Sublime-Theme (the button is in the top right corner of your screen shot), and then import the zip file again to see if that fixes the problem. Also, verify that the Sublime-Theme zip file you downloaded can be manually unzipped since it might be a corrupt file.
Another thing to try is using some alternative plugins. Select Tools -> Plugins -> Available Plugins and then install Dark Look and Feel Themes and Darcula LAF for NetBeans. If those don't work either then there is something fundamentally wrong with the installation of NetBeans.
Finally, this article titled The complete guide to tuning the appearance of NetBeans may be helpful.

Eclipse IDE Double Clicking Java File In Project Explorer Expands It

This may seem very small thing but it annoys me much since I'm used to code in Eclipse. When I double click a java source file in Eclipse it shows classes inside the file (expanding contents of java file) as marked by red circle in the image below. I wanna disable this behavior, I have used Eclipse for a long time and it has never been like this.
You can go to Prefences --> Content Assist and Enable/Disable the contents of Java file

This is a bug in Eclipse, and several people have reported it, e.g., here.
One workaround is to change the "open mode" in the General preferences to single click", which does not have this annoying behaviour.

show code modification overview in ecplise IDE

i am using an eclipse based IDE and have a library with some files that i need to make additions/changes to. what is the best way to quickly see the all the modifications of all files in a list/tab in eclipse IDE?
i know there is the useful "#TODO" tag that shows all tasks in a nice view/tab. as im using this quite heavily, i would like to have a special view/tab that just shows the modifications and separates them from the todos.
EDIT:
thx for the suggestions and the local history tipp.
sorry for not making myself clearer. ive added a screenshot.
when i add "TODO" the tasks show up in the tab marked in red - i dont mind setting manually something (like a bookmark) as im not going to make a lot of changes, but ideally they show up like the tasks or another simple overview.
It's could depend of your version control system.
For each, eclipse purpose an associated plugin with a specific view.
Instead that, you could use the History view (Team/ Show local History after a right clic on a file).
Eclipse keeps a history of your changes for a limited number of days (configured in 'Preferences > General > Workspace > Local History'). You can right click on a file and choose 'Compare With > Local History' to see the changes between revisions.
To track all your changes you need to use one of the source control systems (such as SVN, GIT, ...). Eclipse has plugins to support these systems. Once you have installed one of these you can use the 'Team' menu to commit changes and look at the history.
found it!
by clicking "window" - "Show view" - "other" one needs to select the "bookmarks". the bookmarks then show up as a tab next to tasks.
by clicking the right small arrow the bookmark view menu pops up (similiar to the screenshot above with the task menu). the bookmark view can then be configured/filtered by clicking the "Configure contents..." menu link.

how to remove google sign in button in eclipse

I'm facing a wierd problem. My eclipse, has a google signin button which is occupying some of the space which I do not want to happen. Initially it had "Sign-in to Google" text along with it. I've followed some blog post and set accordingly to show just the icon (I don't remember that blog post link).
But now, the icon is getting replicating .. it is being shown 12 times. It is actually creating childs :P
I've gone through all the options present in Customize Perspective menu, none of them had this button listed. Can someone help me in removing that google sign button from my perspective? One possible suspect is- my eclipse crashes when I suspend and wakeup my machine.
You can use the Window > Reset Perspective... menu command to reset the perspective to its default state, which might eliminate that toolbar and buttons. If that fails, I would create a new workspace and import the projects into it using File > Import > Existing Projects into Workspace.
If you want to try to salvage your existing workspace, it's possible to do so my manually editing Eclipse's internal file that stores your Workbench layout, but it's a bit tricky. Here are the steps I've followed to eliminate a similar repeated toolbar item:
Exit Eclipse.
Find the Workbench layout file, it's path is <workbench>\.metadata\.plugins\org.eclipse.e4.workbench\workbench.xmi. Make a backup of this file before you touch it - this is essential because it's easy to corrupt the file if you change the wrong things.
Open the file in your favorite XML-aware editor - most packages of Eclipse include the XML editor that works just fine1, but be aware that if you use Eclipse to edit the file you can't have Eclipse open on the workspace that contains the workbench.xmi you want to edit.
Find the section of <trimBars> nodes in the XML; from there you have to determine which <trimBars> node you need to edit. In your case it looks like a vertical one, probably with a side="Right" attribute.
Under the correct <trimBars> node you'll find multiple <chlidren> nodes, each with an elementId attribute that should help you identify it; you're looking for <children> nodes that are identified as something related to the Google plugin.
Delete the <children> nodes that seem related to the unwanted toolbar buttons. In your case, it appears that there is an entire toolbar that you might want to eliminate, so you might want to delete the entire containing <trimBars> node.
Save the file and start Eclipse on that workspace.
1Some packages of Eclipse include EMF tools that will open it in a special XMI editor that does not provide a view of the source, only a structural tree view. Depending on how you like to work with XML, this might be easier than editing raw XML.
This is not a perspective but a view. You can hover over that bar with the buttons and click Alt+Shift+F1 to check where this View comes from. Then you can either disable/uninstall the contributing feature (Help -> Installation Details) or check where the feature came from.
If it comes from the IDE, you can open a bug for it. If it is contributed from a third party plugin, contact the developers of that plugin.
There is an eclipse bug concerning duplicate view toolbar buttons in Luna that has recently closed as well. Maybe this solves your problem as well.
Edit: Taken from this bug:
root cause is that in Luna 4.4M5 WorkbenchWindowControlContribution.createControl is called twice, the
first time with a null value for
WorkbenchWindowControlContribution.getWorkbenchWindow() while it is
still being created. This is related to what has been reported here
https://bugs.eclipse.org/bugs/show_bug.cgi?id=427452
second cause is that my createControl(Composite parent) method was calling PlatformUI.getWorkbench().getActiveWorkbenchWindow() instead
of WorkbenchWindowControlContribution.getWorkbenchWindow(). This
resulted in an attempt to create a new Workbench Window, which
recursively calls createControl() again. This has already been
reported here https://bugs.eclipse.org/bugs/show_bug.cgi?id=366708

How can I close an empty pane in Eclipse

I often end up with lots of empty panes in Eclipse that can only be minimized but not destroyed. How do I close these?
Update:
In this screenshot you can see two minimized on the upper left and several on the right hand side. In the center are four more. They only seem to be restorable in the Debug mode.
http://img406.imageshack.us/img406/9900/eclipse1.png
this happened to me, too. What worked for me (based on FilmJ and douncon's comments) was to open a class file, then drag that tab over the top of the empty pane.
Select Window -> Reset Perspective. That should reset the current perspective (what you call "mode") to its' initial state, (hopefully) closing all irrelevant views.
Something seems terribly wrong with your Eclipse. Maybe you should reinstall it. It is possible that you installed a buggy plugin.
First of all, what do you mean by pane? Eclipse has:
Windows (Eclipse itself, e.g. instance)
Documents (tabs)
Views (properties, tasks, explorer, etc)
If by 'pane' you mean document editors, you have problems either with your Eclipse version or most likely one of the installed plugins.
Each View also can be closed (except maybe some project types (perspectives) of which I'm not aware). For CDT (C/C++) you can close practically everything.
I'll recommend you download latest Eclipse version with no plugins, extract it to different folder, and check if that happens again. If yes, please explain more in details (like Eclipse version, perspective you are using, any side plugins, etc).
Also a good places are Eclipse community forum, mailing list and bugz :-)
I had the same problem. For me it helped to go into the right perspective and activate the functionality that caused the window in the first place. Once I reactivated the functionality, in my case "QNX Memory Analysis perspective", I was able to close all the windows one by one.
The conclusion is you have to refill the empty windows with content and then you will be able to close them properly.
So, it's really very easy for this to happen, if you open an editor that's incompatible with the existing editor, you can often end up having to place it outside of the tab list in one of your editor panes, then you might clear or copy that, typically while trying to add that view to a tab list.
In any case, what it's done is create a new editor, and all you need to do is drag some file to that empty editor window giving it some form of context, then close it.
I had the same issue. I followed #zvikico, but instead of just resetting, I first reset and then closed all the perspectives. Please follow the following to fix the problem. It worked for me:
Window -> Perspective -> Reset perspective..
After resetting follow below:
Window -> Perspective -> Close All Perspectives
