如何使用uncrustify格式化程序在java lambda表達式之後正確縮進？

Question

我使用原子與原子美化和uncrustify格式化我的java文件。我想讓一個lambda表達式的縮進只在一個開放大括號後面縮進一級，() -> {。我曾嘗試調整indent_continue屬性，但當我將其設置爲零時，它會變得瘋狂。 （使用4個空格縮進）

時indent_continue = 0，發生這種情況：

public class Test { 
    public static void runTest(Runnable code) { code.run(); } 

    public static void main(String[] args) { 
     runTest(() -> { 
        System.out.println("hello"); // <-- look at this line 
       });        // <-- this one too 
    } 
} 

時indent_continue = 4，其雙縮進：

public class Test { 
    public static void runTest(Runnable code) { code.run(); } 

    public static void main(String[] args) { 
     runTest(() -> { 
       System.out.println("hello"); // <-- look at this line 
      });        // <-- this one too 
    } 
} 

期望的結果：

public class Test { 
    public static void runTest(Runnable code) { code.run(); } 

    public static void main(String[] args) { 
     runTest(() -> { 
      System.out.println("hello"); // <-- look at this line 
     });        // <-- this one too 
    } 
}

在我的系統，Ubuntu的16.10和Atom 1.14.1（其他版本都是一樣的），我解決了這個由更新到最新版本uncrustify 0.64。

因爲我並不熱衷於從源代碼重新構建uncrustify，所以我拉了一個Ubuntu的Docker鏡像：17.04，安裝了uncrustify並將編譯後即可使用的二進制從/usr/bin/uncrustify複製到docker容器中代替我的主機的/usr/bin/uncrustify。
這對我來說非常合適，縮進現在和預期的一樣。
