The Wrapping clained method calls a single line in Eclipse for Java

Question

I was not able to figure out how to wrap each method call in Eclipse . For example, I have this:

 someObject.A().B().C(); 

But I really want this:

 someObject.A() .B() .C(); 

Nothing in the Line Wrapping section in Eclipse seems to give me this result.

Answer 1

In addition to Deepak Azad's answer, you may need the following:

Windows : Window → Settings → Java → Code Style
→ Formatter → Edit → Linear Packaging (tab)

Mac OS : ADT -> Preferences -> Java -> Code Style
→ Formatter → Edit → Linear Packaging (tab)

Then in the list on the left, select:

Function Calls → Qualified Calls

Now, under this list, set the Line Wrap Policy :

Wrap all items except the first item if not necessary

Verify

Separation force, even if the line is less than the maximum line width

Finally, set the indentation policy to (thanks @Turbo ):

Indent by Column

It should give you the exact behavior you requested.

BONUS: Android Studio / IntelliJ Idea:

Mac OS : Android Studio → Settings ( Cmd +, ) → Editor → Code Style → Java → Wrap and Bindings tab → Call Chains

select

Always wrap

and check

Multiline Alignment

Answer 2

Window> Preferences> Java> Code Style> Formater> Editing> Linear Packaging> Function Calls, set the "Line Wrap Policy" to "Wrap all items, each item in a new line."

Answer 3

Window-> Preferences-> Java-> Code Style-> Formater-> Edit-> Line wrapping-> Never join already wrapped strings

Answer 4

If you want to format these segments yourself, you can prevent the reformatting of these eclipse segments by using:

 // @formatter:off ... // @formatter:on 

Perhaps you need to enable this in your settings: http://archive.eclipse.org/eclipse/downloads/drops/R-3.6-201006080911/eclipse-news-part2.html#JavaFormatter

Answer 5

For those who have eclipse code formatting options checked in the original control (for consistent code formatting throughout the command), there is a checkbox in the .settings folder.

The property that this formatting behavior will give you is in the file .settings/org.eclipse.jdt.core.prefs .

Property:

 org.eclipse.jdt.core.formatter.alignment_for_selector_in_method_invocation=80 

Answer 6

in: Window-> Preferences-> Java-> Code Style-> Formater-> Edit-> Line wrapping-> Function call-> Qualified invocation

select the indentation policy as indentation in the column

Answer 7

Customize eclipse formatting format in both java and javascript. increase the maximum line that matches your screen.
