Enum trailing commas get included on the same line as the semicolon ending the line

Enums that get split across multiple lines can lead to the last enum in the series having a , ; on the last line. If a , is specified after the last enum value that should be used as an indicator to create another newline and to place the ; on that newline, or the , should be dropped entirely and it should just become a ; after the last enum value.

I could see arguments for either option, but I’d prefer placing the ; on a newline as this preserves version control history for the line with the previous enum value when a new value is eventually added.

Input:

enum MyEnum {
  AAAAAAAA("aaaaaa"),
  BBBBBBBBBBB("bbbbbbbbbb"),
  CCCCCCCCCC("ccccccccc"),
  DDDDDDDDD("ddddddddddddddddddddddddd"),
  EEEEEEE("eeeeeeeeee"), 
  ;
}

Output:

enum MyEnum {
  AAAAAAAA("aaaaaa"),
  BBBBBBBBBBB("bbbbbbbbbb"),
  CCCCCCCCCC("ccccccccc"),
  DDDDDDDDD("ddddddddddddddddddddddddd"),
  EEEEEEE("eeeeeeeeee"), ;
}

Expected Output:

enum MyEnum {
  AAAAAAAA("aaaaaa"),
  BBBBBBBBBBB("bbbbbbbbbb"),
  CCCCCCCCCC("ccccccccc"),
  DDDDDDDDD("ddddddddddddddddddddddddd"),
  EEEEEEE("eeeeeeeeee"),
  ;
}

Haha, I saw that too! The update to Prettier 2.0 will be in the next release, with the default to trailingComma=“always”

Probably this weekend. I’d like to wrap a couple of things in it, but I could postpone them for a next release
