Alignment

[lucaswerkmeister]

There should be a way to allow alignment of code. For example:

Integer i;    // int
String  s;    // string
File    file; // file

For AST elements (i. e. everything except comments), we could probably get this by implementing “tab stops” in the FormattingWriter and using them in the FormattingVisitor.

Another use case (@luolong here):

value sumOfStuff = calculateSomeStuff(1)
                 + calculateSomeOtherStuff(2);

and

value sumOfStuff = calculateSomeStuff(1) +
                   calculateSomeOtherStuff(2);

Another use case (from #105):

shared actual Boolean equals(Object that)
        => if (is This that)
           then this.thing == that.thing
           else false;

Another one, from https://github.com/ceylon/ceylon.formatter/issues/105#issuecomment-169006171:

void method(A a,
            B b){}
