I use raddebugger on windows as my daily driver. You can add type views in the “Type View” tab, but I don’t remember how to do it anymore and lost it all my types views when my HD died; if you go to ryan fleury on twitter you might be able find to some examples of he uses it;

Edit: a Type View for zig slices will look something like this `type: []? expression array(ptr, len)`

To inspect complex types raddbg provides a “raddbg\_markup.h” that you can at compile time generate type views for your types, if I not mistaken Odin already creates this for you. In my opinion this is your best bet at getting a proper view at MultiArrayList;

Edit2: You can for instace use this function to create views at comptile time

````zig
fn raddbg_type_view(comptime id: []const u8, comptime type_match: []const u8, comptime expr: []const u8) void {
  comptime {
    _ = @export("type_view: {type: ```" ++ type_match ++ "```, expr: ```" ++ expr ++ "```}", .{
      .name = "raddbg_data__" ++ id,
      .linkage = .strong,
      .section = ".raddbg",
      .visibility = .default,
    });
  }
}

````

For instance call `raddbg_type_view("0", "[]?", "array(ptr, len)");` anywhere in your code, I don’t think zig can generate unique numbers to we use as name

I almost only use `array(pointer, len)` in the Watch window, to inspect my types. But be aware that when debugging many of your variables will be unwatchable:

1. Function args always work
2. const declarations like in `const x = foo();` are likely to be unwatchable
3. var declarations works, but they must have unique name inside the function scope for instance having 2 `for(0..N) |i| ...` loops inside your function will make `i` mostly likely to be unwatchable, don’t ask me why
