Radium

A hobby programming language.

Example

test.ra

mod test;

// This is a comment!
// Define entrypoint
func main() {
    let x = 5;
    
    let y = myFunc();
    
    if (x - 5) {
        if (10 - 1) {
            exit(10);
        };

        exit(5);
    };
    
    exit(0);

    //ret y;
}

func myFunc() {
    ret 15 + 15;
}

Usage

./Radium test.ra

Generated Linux x86-64 Assembly:

global _start

_start:
    ; let
    mov rbp, 5
    push rbp

    ; let
    ; call myFunc
    call myFunc
    mov rdi, rax
    push rdi

    ; if
    push QWORD [rsp+8]
    pop rsi
    mov rdx, 5
    sub rsi, rdx
    cmp rsi, 0
    jne .L1
    ; begin true
    ; if
    mov rdx, 10
    mov rsp, 1
    sub rdx, rsp
    cmp rdx, 0
    jne .L2
    ; begin true
    ; exit
    mov rax, 60
    mov rdi, 10
    syscall

    ; end true
.L2: 

    ; exit
    mov rax, 60
    mov rdi, 5
    syscall

    ; end true
.L1: 

    ; exit
    mov rax, 60
    mov rdi, 0
    syscall

myFunc:
    ; ret
    mov rsp, 15
    mov rcx, 15
    add rsp, rcx
    mov rax, rsp
    ret

Todo

• Basic type system (primitives)
• Function parameters
• Better error messages
• Structs
• Else/else if blocks
• Print / begin std lib
• Make local variables referenced by their position relative to stack frame
