Zflecs doesn't support addons

[hacklash]

I'm trying to use the flecs explorer, but it seems impossible with the current state of zflecs.
I need the ecs_singleton_set function from the addons
I tried to workaround this by just using set / ecs_set, but I don't see how to do it with ecs_id() implemented as a c macro

That's my workaround:

const std = @import("std");
const ecs = @import("zflecs");

pub const ecs_app_desc_t = extern struct {
    target_fps: f32 = 0,
    delta_time: f32 = 0,
    threads: c_int = 0,
    frames: c_int = 0,
    enable_rest: bool = false,
    enable_monitor: bool = false,
    init: ?*anyopaque = null,
    ctx: ?*anyopaque = null,
};

extern "c" fn ecs_app_run(world: *ecs.world_t, app_desc: *ecs_app_desc_t) c_int;
pub inline fn app_run(world: *ecs.world_t, app_desc: *ecs_app_desc_t) i32 {
    return ecs_app_run(world, app_desc);
}

pub inline fn singleton(world: *ecs.world_t, comptime T: type, val: T) ecs.entity_t {
    return ecs.set(world, ecs.id(T), T, val);
}

pub inline fn get_singleton_mut(world: *ecs.world_t, comptime T: type) ?*T {
    return ecs.get_mut(world, ecs.id(T), T);
}

var app_desc = flecs_addon.ecs_app_desc_t{
        .enable_rest = true,
    };

const result = flecs_addon.app_run(world, &app_desc);
