Nested braced initializer lists not behaving as expected

[btowntkd]

I am using Clang-Format and I have a particular block of code with nested braced initializers. I would like the code to look like this:

auto test = TheThing{ 
    Arg1{ blorp, bleep, bloop, blop, blip },
    Arg2{ blorp, bleep, bloop, blop, blop, blip } };

Note the desired behavior:

• When the parameter list is too long to fit on one line, each parameter is placed on its own line
• The parameters are indented, not aligned to the end of the first opening brace
• Each parameter contains a nested parameter list, which fits on a single line

But Clang-Format keeps reformatting it thusly:

auto test = TheThing{ Arg1{ blorp, bleep, bloop, blop, blip },
                      Arg2{ blorp, bleep, bloop, blop, blop, blip } };

Note the undesired behavior:

• The first parameter is still on the same line as the open brace
• the parameters are aligned instead of indented

This is the Clang-Format settings I currently use:

---

I placed the settings that seem like they should be the most relevant in this case at the bottom.

Is there a setting I'm missing?

I am using the version of Clang-Format currently included with Visual Studio 2022 - version 13.0.1.

I get:

auto test = TheThing{
    Arg1{ blorp, bleep, bloop, blop, blip },
    Arg2{ blorp, bleep, bloop, blop, blop, blip }
};

with clang-format version 16.0.0 using your example code and format file.
