Concatenating idents

[tawdry jetty]

You don't

Well you can

but you shouldn't

now

I will tell you how

[mental badger]

Not really. Though depending on what it is you want to accomplish there are some loose equivalents. There's the concat (++) operator, which concatenates slices and arrays with compile-time known length. So you can do stuff like "foo" ++ "bar". If you combine this with the fact that you can do @field(namespace, decl_name), you can imagine what you can manage to do

as long as you do this comptime works:

fn callLikeMacro(comptime namespace: type, comptime name1: []const u8, comptime name2: []const u8, args: anytype) @TypeOf(@field(namespace, name1 ++ name2)) {
    return @call(.{}, @field(namespace, name1 ++ name2), args);
}

You can go further by checking the field is actually a function

and other bs

Fully worried but, you do what you can 😛

Reminder to close the post if done 😄

Ah yes the call is callLikeMacro(MyType, "some","world", .{});

And you pass arguments in the .{}

Three dots menu proably

remove the whole call thing to the field thing

and the return type... oh wait I think the return type is fine lol, I failed to get the true return type for the function call

My bad

It's a slightly bigger line in that one, but doesn't matter

you will discover it eventually

if not you can ask
