[cfe-dev] clang-format Java 8 lambda operator

Fri Nov 6 10:32:32 PST 2015

Hello,

I was wondering if it is possible to configure clang-format to not
break the line before the Java 8 lambda operator. For example,

    entries.forEach(entry ->
            assertTrue(String.format("Host set includes '%s'",
                                                entry.getName()),
                                  hostNames.contains(entry.getName())))
;

gets turned into:

    entries.forEach(entry
                    -> assertTrue(String.format("Host set includes
'%s'",
                                                entry.getName()),
                                  hostNames.contains(entry.getName())))
;

This is my .clang-format:
