I'm looking into it.
I'm having a hard time finding out what the correct formatting is,
though. It seems the IDEA version is slightly underconfigured and
relying on a lot of IDEA defaults. The checkstyle configuration isn't
checking a lot of things.
I think we need some textual document describing this. Here's a shot at
some of the issues:
-----------
1) newline + indent by one before 'extends' and 'implements'
public class Bla
extends A
implements B
{
QUESTION: is this right?
- throws on a new line, exceptions on one line; wrapped exceptions same
indentation as the throws:
public void bla()
throws Exception, Exception, Exception, ...
Exception, Exception
QUESTION: is this right?
(I prefer the following, btw:
public void bla()
throws Exception,
Exception,
Exception
)
2) Wrap all arguments for constructors, method invocations etc using
indent by column:
foo.bar().something( a, b, c,
d, e );
QUESTION: Is this right?
Although eclipse has some problems, it'll render it as:
foo.bar().something(
a, b, c,
d, e );
I personally prefer:
foo.bar().something(
a, b, c, d, e
);
or possibly
foo.bar().something( a, b,
c, d, e
);
or this, as eclipse doesn't allow ');' to be on a new line when
wrapping:
foo.bar().something( a, b,
c, d, e );
3) Wrap long method-invocation chains, indent on column:
foo.bar().baz()
.bla()
.blup()
Mixing this with long argument lists gets interesting..
QUESTION: Is this right? I've also seen
foo.bar().baz()
.bla().blup()
4) All { and } on a single line, not indented:
for ( a; b; c )
{
// indented code
}
5) 'if' parameters are continuously wrapped, indented by one:
for ( a = a + a + a
+ a + a; a < b
+ b + b + b; a
+= b )
{
}
QUESTION: Is this right?
(personally i'd prefer the 3 parts to be on separate lines and indented
one more in this case, makes it more readable:
for ( a = a + a + a
+ a + a;
a < b + b + b
+ b;
a += b )
{
}
Maybe even indent on column although I hate non-tab-aligned indents.. ;)
)
6) Line wrapped operators at the beginning of the line:
a + a + a
+ a;
(instead of:
a + a + a +
a;
)
(possibly not indented, depending on context).
7) Spaces after ( and before ) except when empty or when it's a
typecast:
( (Typecast) something ).foo()
-----------
If someone could confirm my assumptions I'll make sure the eclipse
codestyle reflects this, and possibly checkstyle too.
