A small scripting language. I promise anything in ./src will never be more than 5k LoC okay.
- Small
- Simple FFI API with C (no stack wrangling)
- Garbage Collected
- Slow but small
- Lack of Closure but small
- No Object Oriented Programming but again it's small
- Cute and Funny
- Hello World
print("Hello, World")
- Variable
var a = 10; // integer
var b = 20.5; // float
var c = "Hello, World"; // string
var d = [ a, b, c ]; // array
var e = { "name": "foo", "age": d[0] }; // table
print(e["name"])
- Branching
if(age < 10) {
print("You are child")
} else if(10 <= age && age < 17) {
print("You are teenage")
} else {
print("You are adult")
}
- Loop
var i = 0;
while(i < 10) {
i = i + 1;
}
- Function
fun main(args) {
print("Hello, World")
return 0;
}
- C FFI
