Is there a way to get eclipse to stop erasing existing line breaks? If I have a method signature like this, I can't figure out how to get eclipse to leave it alone:
void foo(
int arg1,
int arg2,
int arg3,
int arg4)
{
// ...
}
With various settings it will either collapse the arguments down to one line, or wrap them at some margin like this:
void foo(
int arg1, int arg2,
int arg3, int arg4)
{
// ...
}
With "Wrap all elements, every element on a new line" it does preserve this whitespace, but it will ALWAYS wrap, which isn't what I want. I'd like eclipse to apply formatting for indentation and braces and such, just without ever deleting (or inserting) any line breaks.
The formatting of arguments is an old subject, but the one new formatting feature introduced in 3.5 is:
The Java code formatter can now optionally preserve user line breaks by not joining lines in code or comments.
For example, the wrapped lines of the return statement in following test case:
Example of Code to Format
will be preserved by the formatter when the "Never Join Lines" preference is used, and now produces the following result:
Coded Formatted with Never Join Lines
This preference can be configured on the Java > Code Style > Formatter
preference page. See the Never join lines
option on the Line Wrapping
and Comments
tab.
That may help, but otherwise there is not much new features on that front in 3.5.
