What changed with this PR:

Formatting of array initializers is aligned with arrays in Prettier JS, in that numeric arrays can now be printed concisely.

Example

Input

int[] empty = {};

int[] emptyWithComments = {
  // dangling comment
};

int[] shortArray = { 1, 2, 3, 4, 5 };

int[] longArray = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25 };

int[] variousBases = { 0b1010, 0xFF, 0123, 3.14159f, 2.71828d, 100L, 0b1101, 0xABC, 0456, 1.41421f, 1.61803d, 200L, 0b1111, 0x7F, 0777, 9.80665f, 6.62607d, 300L };

int[] signedNumbers = { -1, +2, -42, +100, -3.14, -500, +600, -7000, +80, -90, +101, -202, +303, -404, +505, -606 };

int[] signedWithComment = { -1, -/* negative two */ 2, +3, -4, +5, -6, +7, -8, +9, -10 };

int[] withBlankLines = {
  1, 2, 3, 4, 5,

  6, 7, 8, 9, 10,

  11, 12, 13, 14, 15
};

int[] withTrailingComments = {
  1, // comment on one
  2, // comment on two
  3
};

int[] withLeadingComments = {
  1,
  // comment before 3
  3,
  4
};

Object[] mixedArray = { 1, "hello", true, null, 2, "world", false, 3, "foo", true, 4, "bar", false };

int[] expressionArray = { 1 + 1, 2 * 3, getValue(), 4 + 4, 5 * 5, getData(), 6 + 6, 7 * 7, compute() };

int[][] nestedSingular = { { 1 }, { 2 }, { 3 } };

int[][] nestedMultiple = { { 1, 2 }, { 3, 4 }, { 5, 6 } };

int[] arrayWithInternalNodeComment = {
  1, 2, 3
  // internal node comment
};
