The following are a few of the main features to be found in Polystyle's Java formatter.

To see a preview of Polystyle in action, use the Step 1, 2, 3 links above.

Context-Sensitive Formatting Polystyle formats entities depending on their location in the source. The default example file gives examples for formatting array creation two ways. The first applies when created inside a class body: Example: class C { private final int [][] array = new int [][] { { 1, 2, 3 }, { 1, 2, 3 }, { 1, 2, 3 } }; } The second applies when inside expressions: Example: for (int [] i = { 1, 2, 3 }; false; i++) { }

C++ Style Comment Alignment: Polystyle intelligently groups together and aligns C++ style comments. Example: int i = 0; // id counter s.optimize(i, a, b); // optimize transaction do { i++; // scan through } while (s.inspect(i)); // find any bad ids // clean up bad files for (int j = 0; i != h; j++) { File f = open(myFiles[j]); // get latest copy f.delete(); // wipe it out }
