I use Eclipse IDE and Window Builder Pro for create window.
When I go to the source code I see a big indent text. How to delete ?
How about good old Shift + Tab?
If by "how to delete" you mean to say that you want to decrease the indentation level, try this:
Go to
Window->Preferences->general->Editors->Text
Editors
There specify the indentation level under :
Displayed Tab Width.
Additionally you can customize you formatting in Eclipse as :
Go to
Window->Preferences->Java->Code
Style->Formatter
Select the formatter and press Edit. Use whatever suits you.
Then Select the text you want to format and press Ctrl+Shift+F
If you want to fix indent only you can select lines and press Ctrl-I.
Take a look at Eclipse keys
Most likely you insert tab character which is being expanded to 8 positions in target IDE.
Change setting in Eclipse to insert 4 spaces (or whatever your style is) when tab is pressed.
Then you can try to reformat your file in Eclipse. Also, you can use sed to replace \t with 4 spaces.
If you like the way your formatter is set up for the rest of your code, perhaps telling the formatter not to work on this section would be desirable. Then you can unindent the section to make it visually appealing and not worry about it changing formatting.
Linked solution works in Eclipse 3.6.

I am using java on Intellij and I wonder if it is possible to make it so that it automatically places quotations System.out.println(here);
Thanks
Yes, it is possible.But a bit tedious. (EDITED)
ECLIPSE
you need to know that Ctrl+space opens options for autofill.
you need to create a simple template at
Window>Preferences>Java(dropping menu)>Editor>Templates>New...
In the open window at Name type: Syso
at Pattern: System.out.println("")
Make sure the checkbox Automatically insert is on.
Apply and close
Now every time you type Syso and hit Ctrl+Space there will be first option
of autofill with quotations. Profit.
oof, didn't notice about Intellij , my bad. Thought about Eclipse. Well here is one for Intellij
INTELLIJ
I believe the Intellij version of cntl+space is Tab button
Go to Settings>Editor>Live Templates
Pick any template and press Plus icon. Choose Live Template
In abbreviation type your desired word (I would put: Syso)
In Template txt type : System.out.println("")
Make sure the box with Reformat according to style is checked
Now every time you type Syso you can hit Enter and have PROFIT!
Unchecking every option under 'Indentation' in the Eclipse formatter profile editor still shows the example 'UNDEFINED' indented all the way past the opening bracket of the Enum 'MyEnum'. A fresh Eclipse configuration may not do this, but I have to start from the profile of this project. Can someone give me a hint what configuration variable may be causing this obscene level of indentation in enums?
In the formatter profile editor, take a look at the tab named Line Wrapping then click on enum declaration. I bet you will see that Indent on column is selected as Indentation policy. Changing the Indentation policy to another value will reduce the amount of indentation. Alternatively you can change the Line wrapping policy to Do not wrap.
I want the values of two (or more) arrays to be lined up like in the bottom row of this example.
Is there a way to do this in Eclipse?
You can switch off Eclipse formatter (see https://stackoverflow.com/a/3353765/5277820) and format the lines by yourself.
If I misunderstood your question I apologize, I assume you are talking about the formatting in Eclipse.
(Windows version)
In Eclipse, go to
Window -> Preferences -> Java -> Code Style -> Formatter.
Open the profile (should be default, but I'd suggest creating your own)
In the Line Wrapping tab, there is a "Maximum Line Width" that you can change (default is 80). That will prevent lots of these automatic line wrappings.
See the image below. For the white spaces you need to navigate to the "White Space" tab.
When I first learned Java, I was using an IDE called "BlueJ." It had this feature called "Scope Highlighting" which made it very easy to read blocks of code. Now I've moved on from BlueJ and began using Eclipse. I'm currently in the process of customizing Eclipse to my liking and would like this Scope Highlighting feature inside Eclipse.
I've searched everywhere for an answer on how to do it but I cannot find any information pointing to a solution for doing it in Eclipse.
Here's a picture to demonstrate what Scope Highlighting looks like:
I think the best option for you is EditBox, a scope highlighting plugin for Eclipse:
http://editbox.sourceforge.net/
I'm afriad that closest you can get is Shift + Alt + arrow_up
It is selecting wider block of code. pressing this few times will give you very similar result to what you are searching for. I use it often.. it is useful, also for refactoring.
EDIT: As #j2emanue said: you can just double click the delimiter (like a bracket) and it will highlight the entire scope.
you can use Shift + Alt + arrow_up but many people dont realize you can just double click the delimiter (like a bracket) and it will highlight the entire scope. Try double clicking your if statements bracket for example and watch eclipse highlight the entire scope. It works with any delimiter. so you can use parenthesis as well.
as a side note: if your using intelliji checkout this plugin works great: https://github.com/izhangzhihao/intellij-rainbow-brackets#screenshots
This isn't exactly what you're after but you can put your cursor in a method and then click the Show Source Of Selected Element only button on the toolbar. Your editor gets reduced to just that method. Click again and your back to your entire file.
I doubt eclipse does have the same function as blue j.The best advise I can give you, is to change your theme to your liking which would enable you to easily select and highlight the block of code...and to customise your theme , go to http://eclipsecolorthemes.org/. ....
If you still have a problem, go to http://codejava.co.uk/contact.html and send your email.you can create a dummy one if want, then I will send you XML files I use for my eclipse themes.
can Bracketeer do this ? its an eclipse plug in ..

Maybe you will also like the VSCode extension "Blockman". It highlights nested code blocks based on curly/square/round brackets, html/xml tags and Python/Yaml indentation. (I am the author of Blockman).

Currently the Eclipse autocompletion seems only to be triggered after a dot or on parameters, I want to use it for variables too, e.g. if I have
String test="hello";
then I want the autocompletion to suggest "test" if I start typing "t" in the next line (e.g. if I intent to change the value of the variable test).
Is there any Eclipse plugin capable of doing this? I already checked the Eclipse content assist options, but seems like there no option for what I want? Thanks for any hint!
First of all, thanks for all the replies. They are correct, however you have to press the key combination each time. Here's how it's done automatically:
That plug-in is not necessary any more. Just go to
Preferences > Java > Editor > Content Assist
and paste:
ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz.
into the "Auto activation triggers for Java:" field.
This simply triggers auto activation after any English alphabet character and after dot.
https://bugs.eclipse.org/bugs/show_bug.cgi?id=159157#c12
Works fine :-)
Hint: You probably want to additionally set the auto activation delay to 0, at least if you are used to visual studio ;-)
In addition to the suggestions above, did you try ALT + / it does incremental matching? No?
ctrl + space
If you press ctrl+space key combination, eclipse will show you the code assist window.
Type t and then hit ctrl+space, it will show you possible matches
You can press "t" and then Ctrl+Space..
is it?
In Eclipse
Window--->Preferences---> search for Content Assist under Content Assist go for Advanced
and check the Java Praposals.
done.
