Glide

A programming language.

Currently, this includes:

• Static typing

• Generics, with monomorphization

• Type inference on function calls

  func identity<T>(t T) T {
      t
  }
  
  identity("Foo")
  

• Basic types, including Ints, Bools, and Strings

• Functions, usable as values

  func a() {
      println("a")
  }
  
  func main() {
      let f = a
      f()
  }
  

• Local variables

  let x = 2
  let y Int = 3
  

• if/else expressions

  let x = if cond1 {
      1
  } else if cond2 {
      2
  } else {
      3
  }
  

• Single-line comments

  // This is a comment
  

• Attributes

  attribute Happy
  
  [Happy]
  func happy() {
  }
  

• Packages with public and private visibility

• Native code generation using LLVM

Examples

Hello world:

func main() {
    println("Hello World!")
}

Fibonacci numbers:

func fibonacci(n Int) Int {
    if eqInt(n, 0) {
        0
    } else if eqInt(n, 1) {
        1
    } else {
        add(fibonacci(sub(n, 1)), fibonacci(sub(n, 2)))
    }
}

Usage

First, install LLVM.

Run the Hello World example with

cargo r -- compile ./examples/hello.gl -o hello.o
clang-14 -no-pie hello.o -o hello
./hello
