Wrote my first data structure using comptime to replace an ArrayList where the maximum size is known at compile time. As I use it as a stack, it only implements append and pop as that is all I need.

#zig #dev

pub fn ConstStack(comptime T: type, size: comptime_int) type {
    return struct {
        items: [size]T = undefined,
        len: usize = 0,
        const Self = @This();

        pub fn append(self: *Self, item: T) !void {
            if (self.len == size) {
                return error.OutOfMemory;
            }
            self.items[self.len] = item;
            self.len += 1;
        }

        pub fn pop(self: *Self) ?T {
            if (self.len == 0) return null;
            self.len -= 1;
            return self.items[self.len];
        }
    };
}

If we aren't supposed to write our own database, why is it so much fun to do?

#

I'm currently watching the CMU Database Group Lectures to learn more about #database systems and design. And I just noticed how refreshing it is to learn this way and I somewhat miss being at a university, working into the depth of a topic. Work feels shallow in comparison.

Cooked a large batch of #vegan Bolognese.

#gamedev progress on hotel game:

• did some further refactoring to rendering function
• added room highlighting when building new rooms and selecting bed rooms for new guests

Not sure if I should be proud or embarrassed about this #rust code :D

// mark building tile
if let Some(mut r) = match game.mouse_action {
    MouseAction::BuildGrill => Some(Room::new_grill()),
    MouseAction::BuildStairs => Some(Room::new_stairs()),
    MouseAction::BuildBedroom => Some(Room::new_bed_room()),
    MouseAction::BuildCorridor => Some(Room::new_corridor()),
    MouseAction::BuildRestaurant => Some(Room::new_restaurant()),
    MouseAction::BuildWineCellar => Some(Room::new_wine_cellar()),
    _ => None,
} {
    // rendering code
}

Insights from the weekend:

• Claude Sonnet 3.7 is the first #GenAI I tried out that actually produced usable code. The code is not pretty but it was the first time I was impressed by an AI system being able to produce non-trivial code and being able to adjust it to feedback.
• I should stop using #python for one off scripts to convert data. The #rust ecosystem has a similar maturity. Building such scripts takes roughly the same time in both languages, but the rust system will finish the job order of magnitudes faster.
• When your rust program feels slow you probably forget --release.

#gamedev progress:

• generalized character rendering to share code between guests and employees.
• Added support for different animations. Animations are determined by the current action executed by the character.
• Employees are now rendered with new character system.

#

#gamedev progress on hotel game:

• further work on sprites in new format
  • 32x32 for characters
  • 48x48 for rooms
• added roof to the hotel
• shirt and pants color of each guest is now randomized
