What I want (when formatting in Eclipse):
Path file = write(FILE_SYSTEM.getPath(fileName), transactionStrings,
CHARSET, CREATE, TRUNCATE_EXISTING, WRITE);
What it is doing:
Path file =
write(FILE_SYSTEM.getPath(fileName), transactionStrings, CHARSET,
CREATE, TRUNCATE_EXISTING, WRITE);
Line length is 80, tab widths set to 3.
OK, found the solution.
Windows > Preferences > Java Code Style > Formatter > Edit
Line Wrapping > Expressions > Assignments > Line wrapping policy: Wrap all elements, except first element if not necessary.
Set line length in Eclipse formatter (Window->Preferences->Java->Code style->Formatter) to higher value.

How can I set the auto-format feature (Alt+Shift+F) to insert a newline on interface methods in Netbeans 10? E.g.,
As you can see the new line only works in class definitions (class Foo2) but not in interfaces (interface Foo1).
Can't seem to find the right setting at Options > Editor > Formatting > PHP > Blank Lines
I can't find a way to do exactly what you want, but it is possible to format the code to insert a blank line between public function bar1(); and public function bar2(); by setting Tools > Options > Editor > Formatting > PHP > Blank Lines > Before Function to 1, and After Function to 0.
However, the (possibly unwelcome) side effect is that you will get a blank line before every function, so formatting your file with those settings results in this:
I'm guessing that you don't want the formatting to insert blank lines on line 5 and line 13 in the screen shot above, but I don't see how to prevent that while also having a blank line on line 7.
FYI, here are all the settings specified for Tools > Options > Editor > Formatting > PHP > Blank Lines:
Is there a way I can configure eclipse to prefer breaking a long assignment by putting the '=' on a new line, and avoid breaking on a '.' character for a method invokation. I've noticed a bunch of settings like:
<setting id="org.eclipse.jdt.core.formatter.alignment_for_arguments_in_allocation_expression" value="16"/>
that can be added to an xml file that can be used to specify formatting, but I'm not sure which settings I should change to have the desired effect. Are these configurations documented somewhere (I tried Googling some relevant terms to no avail).
The setting you're looking for regarding assignment line breaks is in:
Window (menu) > Preferences > Java > Code Style > Formatter
> Edit... (on active profile) > Line Wrapping (tab) > Expressions
> Assignments
where you can select your preferred line wrapping policy and indentation policy.
As for avoiding line breaks, still on the Line Wrapping tab, change the line wrapping policy on Function Calls > Qualified invocations to "Do not wrap".
In both cases, you can play with the preview width to see what effect the various policies will have on how your code is formatted.
Eclipse keeps auto formatting upon save, for example: it is insisting the following code should be in a single line once I save, despite breaking it up the way I want to.
#Transactional(rollbackFor = DataAccessException.class, readOnly = false, timeout = 30, propagation = Propagation.SUPPORTS, isolation = Isolation.DEFAULT)
Window > Preferences > Java > Editor > Save Actions.
Can also be configured at the project level. Project > Properties > Java Editor > Save Actions.
Absolutely maddening improvement. For if statements do the following:
Window | Preferences | Java | Code Style | Formatter | Control statements tab
Select Keep simple if on one line.
You might also try the Line wrapping tab
This is a Late answer, But just for novice to understand it clearly I have a snapshot of the setting.
Please follow the path on left.
And change highlighted setting.
If you wish to keep the auto-formatter, but don't want this behavior, you can also configure it in the fomatter :
right click on the project -> properties -> java code style -> formatter
(If you don't have a project specific formatter the global configuration can be accessed this way : Window -> Preference -> Java -> Code Style -> Formatter).
Edit... the active profile, open the Line Wrapping tab, and there check the Never join already wrapped lines option.
This way you can wrap lines wherever you want and eclipse won't remove your line breaks (which is a must if you wish to have readable lambda expressions), but keep the formatter active.
This option is there at least since eclipse Luna
Here is a screenshot where this option is :
Just wanted to add a tip. If you want to avoid the line wrapping you can simply increase the "Maximum line width" value to something enormous. As long as that is sufficiently high eclipse won't do any wrapping.
Preferences > Java > Code Style > Formatter > Edit > Line Wrapping > Maximum line width
When I format in eclipse long lines become from this :
String str = instance.someMethod("jhdajhajsha").someOtherMethod("sakjsaksja");
to this :
String str = instance.someMethod("jhdajhajsha")
.someOtherMethod("sakjsaksja");
How do I prevent this?
Good practice is to place line-break like that.
Any way you can edit you format setting
Window > Preferences
It will show the Preferences Window
In that Expand the Java then Code Style and select Formatter
Here you can edit Active profile
In the edit, Line Wrapping tab, The General Settings there is a option to set the
Maximum line width give the maximum limit here, When you format, it will break the line more than this limit
windows > preferences > java > code style > formatter
Create a new profile. in the profile setting, select Line Wrapping [tab]
disable line wrapping for all . (class declaration, constructor declaration etc etc etc.. )
How can I set my Eclipse's code formatter to allow code rows longer than 80 characters. I know that very long lines is hard to read but in my opinion 80 characters per line is very small value for wide screen monitors.
In Preferences, go to Java > Code Style > Formatter and edit/create the formatter and go to tab Line Wrapping. There in you can set the Maximum line width.
Further on you can in General > Editors > Text Editors also set the Print margin column which should shift up that margin (a 1px wide vertical line in the right side of your code) to the desired position. This however doesn't affect the formatter, only the human eye.
This answer was a bit old, and the path have changed with new versions of Eclipse.
To set the Maximum line width, go to Project > Properties. In the Properties window, go to Java Code Style > Formatter. Select your Active Profile (let the one which is already selected, this is the one you are currently using) and click on Edit. In the tab Line Wrapping, you can set the Maximum line width (80 by default). You can also go to the tab Comments and uncheck Enable Line Comment Formatting if you want your comments not to be formatted on multiple lines with Ctrl+Shift+F.
Don't forget to change the name of the Profile Name; if you don't change it, you won't be able to save your changes (provided the one you are editing is Built-In
Also, you can set the Print margin column in Window > Preferences > General > Editors > Text Editors.
Regarding the "small" value (80), this has just changed (in August 2014).

A three-years old issue is finally addressed:
bug 356851: Default line size of Java code formatter should be increased to 120
It is not mentioned in the Eclipse Project 4.5 (Mars) M1 - New and Noteworthy, but it is still "Verified for 4.5 M1 using I20140804-2000 build".
