            Bug ID: 38909
           Summary: [clang-format] Support generators in C++
           Product: clang
           Version: 7.0
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Formatter
          Assignee: unassignedclangbugs at nondot.org
          Reporter: dennis.felsing at sap.com

We use lambdas to write code like:

int main()
{
    int newValue;
    If(match, [&]() {
        newValue = false;
    }).ElseIf(match2, [&]() {
        newValue = true;
    }).Else([&]() {
        newValue = false;
    });
}

Unfortunately clang-format since version 5 started indenting the ElseIf:

$ clang-format -style webkit x.cpp
int main()
{
    int newValue;
    If(match, [&]() {
        newValue = false;
    })
        .ElseIf(match2, [&]() {
            newValue = true;
        })
        .Else([&]() {
            newValue = false;
        });
}

I couldn't find an option to turn this behaviour off.
