Selene is a statically-typed, imperative and procedural programming language compiled to LLVM IR.
The language is designed to be as easy to grasp as possible, while still providing a powerful set of features. It aims to combine the best of all worlds, providing a simple and easy-to-understand syntax, while still being powerful enough to be used in real-world applications.
Basic input/output:
func main () {
check_typed();
}
func check_if_typed_apple(reading: string) {
variable := "apple";
if reading == variable {
println("You typed 'apple'");
} else {
println("You didn't type 'apple'.");
check_typed();
}
}
func check_typed() {
println("");
printf("Type something: ");
reading := readln();
println("You typed $reading");
check_if_typed_apple(reading);
}Structs:
data Point(
x: int32,
y: int32,
signed: bool
);
func main() {
mut point := new_point();
print_point(point);
change_point(point);
print_point(point);
}
func new_point() :: Point {
return @Point(100, 400, true);
}
func change_point(point: mut Point) {
point.x = 200;
point.y = 800;
point.signed = false;
}
func print_point(point: Point) {
println(point.x);
println(point.y);
println(point.signed);
}Traits:
data Map(
foo: int32,
remainder: int32
)
trait Fooable(
new(foo: int32) :: Map,
fooat(self) :: int32
)
make Map into Fooable {
func new(foo: int32) :: Map {
return @Map(foo, 42);
}
func fooat(self) :: int32 {
return self.foo;
}
}
func main() {
println("Hello, World!");
new := Map@new(4);
println(new.fooat());
map := @Map(42, 64);
println(map.fooat());
new2 := map.new(8);
println(new2.fooat());
}Lambdas:
func callback(value: int32, scope: lambda(int32) -> int32) {
result := scope(value);
println(result);
}
func main() {
println("Hello, World!");
callback(2, lambda|x: int32| x + 12);
callback(4, lambda|x: int32| x + 24);
callback(8, lambda|x: int32| x + 36);
