Ctrl+/)
- Bracket matching and auto-closing
- Code folding
Siyo at a Glance
Siyo is a modern programming language with built-in concurrency primitives, actor-based message passing, and structured concurrency through scope/spawn.
struct Point {
x: int,
y: int
}
impl Point {
fn new(x: int, y: int) -> Point {
Point { x: x, y: y }
}
fn distance(self, other: Point) -> float {
imut dx = self.x - other.x
imut dy = self.y - other.y
toFloat(dx * dx + dy * dy)
}
}
fn main() {
imut p1 = Point.new(0, 0)
imut p2 = Point.new(3, 4)
println("Distance: {p1.distance(p2)}")
}
Concurrency
actor Counter {
count: int
}
impl Counter {
fn new() -> Counter {
Counter { count: 0 }
}
fn increment(self) -> int {
self.count = self.count + 1
self.count
}
}
fn main() {
imut counter = Counter.new()
scope {
spawn counter.increment()
spawn counter.increment()
}
println("Count: {counter.count}")
}
