I am working on some OpenGL but it is extremely annoying that, rather than just putting

float [] verts = {
    -0.5f , -0.5f ,
     0.0f ,  0.5f ,
    -0.5f ,  0.5f
};

for the vertices of a triangle, I have to use

//@formatter:off
float [] verts = {
    -0.5f , -0.5f ,
     0.0f ,  0.5f ,
    -0.5f ,  0.5f
};
//@formatter:on

which, not only looks horrible, also is inefficient and requires moving the opening and closing formatter tags if I later decide to put another array in there. How do I go about making the formatter accept the first format rather than the "wrapped onto one line" format?

Hello James,

you can modify Eclipse Java Formatter:
- Window -> Preferences -> Java -> Code Style -> Formatter
- Edit...
- Line Wrapping tab
- in the tree, select Expressions -> Array initializers
- in the "Settings for array initializers" group, use "Wrap all elements, every element on the same line" (or another one which is matching what you want exactly)
