maybe I'll do some KDL stuff today. As a treat.

Initial custom themes support has landed in @conjured.ink's stall software and it's very fast, and very easy to write custom themes for (assuming you know a little bit of HTML/CSS!)

Highlights:

VERY fast jinja-style templates w/ layouts & partials
KDL-based metadata ;)
No framework needed!
Easy packaging

Our shops are more than just ecommerce: they're going to be able to do newsletters/blogging, POSSE, and general custom websites, all with an EXTREMELY small footprint that will be cheap or free!

Like this whole thing? Please support us if can comfortably do so: https://mastodon.social/@conjured_ink/115347161647458655

Seeking feedback from Bevy and Big Brain users: how does this new API look?

Under the hood, this would be a high-performance, low-overhead API powered by Observers, but this is all you would actually need to write yourself.

I'm pretty sure I can get this to work with Bevy's current featureset, including the Very Fun async actions situation here.

#Bevy #BigBrain #GameAI #Rust #RustLang

#[derive(Debug, Default, Clone, Copy, Component)]
pub struct Thirsty;

#[scorer_for(Thirsty)]
pub fn score_thirsty(score: Score, thirsts: Query<&Thirst>) -> Score {
score.update(thirsts.get(score.actor()).unwrap().thirst)
}

#[derive(Debug, Clone, Copy, Component)]
pub struct Drink { rate: f32, per: Duration }
impl Default for Drink {
fn default() -> Self {
Self { rate: 0.5, per: Duration::from_millis(500), }
}
}

#[action_for(Drink)]
pub async fn drink_action(
action: Action<Drink>,
mut thirsts: Query<&mut Thirst>
) -> Result<(), ActionFailure> {
while let Ok(mut thirst) = thirsts.get(action.actor()) && thirst.thirst > 10.0 {
action.check_cancelled()?;
thirst.thirst -= action.data().rate;
action.sleep(action.data().per).await;
}
Ok(())
}

fn spawn_entity(cmd: &mut Commands) {
cmd.spawn((
Thirst(70.0, 2.0),
Thinker::new()
.picker(FirstToScore { threshold: 0.8 })
.when<Thirsty, Drink>(),
));
} — #[derive(Debug, Default, Clone, Copy, Component)] pub struct Thirsty; #[scorer_for(Thirsty)] pub fn score_thirsty(score: Score, thirsts: Query<&Thirst>) -> Score { score.update(thirsts.get(score.actor()).unwrap().thirst) } #[derive(Debug, Clone, Copy, Component)] pub struct Drink { rate: f32, per: Duration } impl Default for Drink { fn default() -> Self { Self { rate: 0.5, per: Duration::from_millis(500), } } } #[action_for(Drink)] pub async fn drink_action( action: Action<Drink>, mut thirsts: Query<&mut Thirst> ) -> Result<(), ActionFailure> { while let Ok(mut thirst) = thirsts.get(action.actor()) && thirst.thirst > 10.0 { action.check_cancelled()?; thirst.thirst -= action.data().rate; action.sleep(action.data().per).await; } Ok(()) } fn spawn_entity(cmd: &mut Commands) { cmd.spawn(( Thirst(70.0, 2.0), Thinker::new() .picker(FirstToScore { threshold: 0.8 }) .when<Thirsty, Drink>(), )); }

Big Brain, btw, is designed to be data-oriented, so I might provide an API that lets you define game AI in .kdl files that look like this. It could also, for example, eventually use a hypothetical node editor (thing Blender Geometry Nodes), to define the same data.

#KDL #Bevy #BigBrain #GameAI

Thinker {
picker FirstToScore threshold=0.8
when Thirsty {
GoToWater
Drink
}
when Hungry {
Eat
}
or Bored Paranoid {
Thinker {
when EnemySpotted {
ShootEnemy
}
when FlowersSpotted {
WalkToFlowers
PickAFlower
SmellFlower
}
otherwise {
Parallel {
Wander
HumATune
}
}
}
}
} — Thinker { picker FirstToScore threshold=0.8 when Thirsty { GoToWater Drink } when Hungry { Eat } or Bored Paranoid { Thinker { when EnemySpotted { ShootEnemy } when FlowersSpotted { WalkToFlowers PickAFlower SmellFlower } otherwise { Parallel { Wander HumATune } } } } }

Hold up can we talk about how cute this little file tree icon for KDL files in Zed is?!

I see the Kubernetes team have finally admitted that YAML is not fit for purpose, so they’ve invented… JSON5. Kind of?

https://kubernetes.io/blog/2025/07/28/kubernetes-v1-34-sneak-peek/

Srsly, folks, why are you defining a thing that already exists?

Excited for the @bevy scene format. I poked at it a bit and it's definitely something that would look really darn good in #KDL. This is using the proposed number type suffix syntax.

Once the format lands, I might write an adapter that lets you write scenes in KDL and hot reload w/o recompile!

ok hear me out

what if

#KDL args/prop vals could be nodes, too? This seems... tremendously silly, but I can imagine use cases even if I can't imagine how to make it look reasonable.

language design challenge: If you were to support unquoted paths in a language like #KDL, how would you do it in a way that didn't have massive footguns?

See https://github.com/kdl-org/kdl/discussions/494 and send us your answer there! Maybe there's still a way :)

#KDL v2 is such a delight to use omfg

I just really really really wish we had found a good way to allow / in bare idents. One of those sins of the past thing where we would’ve had to completely change the comment syntax to support it :(

Probably my only regret about the language right now tbh.
