[clang-format] `AlignConsecutiveDeclarations` does not distinguish between functions and variables

[timblechmann]

considering this code:

float a;

int bbbbbbbbbbbbbb;

std::vector< std::vector< std::vector< int > > > function()
{
    return {};
}

formatting it via AlignConsecutiveDeclarations: AcrossEmptyLinesAndComments, gives:

float                                            a;

int                                              bbbbbbbbbbbbbb;

std::vector< std::vector< std::vector< int > > > function()
{
    return {};
}

it would be great to have the option to only align consecutive declarations for declarations of the same kind, so that function and variable declarations are not aligned:

float a;

int   bbbbbbbbbbbbbb;

std::vector< std::vector< std::vector< int > > > function()
{
    return {};
}

Can confirm. It also tries to align deleted functions with global constants.

constexpr int X = 1;

void func()     = delete;

Any progress / any options to configure variables separate to methods/functions?

It would be also very nice to be able to configure maximum distance of "neighboring" declarations to be grouped and aligned, and set it to something sensible like 2-3 lines.

I have an interesting edge case in my codebase where there's a pretty long extern const declaration, followed by about 10 lines of preprocessor definitions, and yet all the function declarations that are below try to align to that const declaration at the top, which indents them waaay too far to be helpful or readable.
