如何删除vim中括号内的重复行？

I have json file that has duplicate values that I wish to remove using vim. Here is an example:

我有json文件，它有重复的值，我希望使用vim删除。这是一个例子：

{
  { "greetings" : [
      "hello",
      "hello",
      "hola",
      "hola"
    ]
  }, ...
}

至

{
  { "greetings" : [
      "hello",
      "hola"
    ]
  }, ...
}

So far, I was able to successfully remove all duplicate lines expect those at the end. There is an extra ',' that breaks my matching and I end up with

到目前为止，我能够成功删除所有重复的行，期望最后的那些。有一个额外的'，'打破我的匹配，我最终

{
  { "greetings" : [
      "hello",
      "hola",
      "hola"
    ]
  }, ...
}

Since duplicated lines are adjacent to each other, you can use \1 to match a string again, and use ,\? to make the comma optional:

由于重复的行彼此相邻，您可以使用\ 1再次匹配字符串，并使用\，？使逗号可选：

:%s/^\(.\+\),\?\n\1\n/\1\r/gc

If you need to limit the search and replace to certain blocks, you can use g/../ to match the block first:

如果您需要限制搜索并替换为某些块，可以先使用g /../匹配块：

:g/[\[^[\]*]/%s/^\(.\+\),\?\n\1\n/\1\r/g
