Function mlem_asm::parse::parse_program

pub fn parse_program(program: &str) -> Result<Program, Vec<(u64, String)>>

Parse an entire program, returning either a ready-to-execute MLeM program or a Vec of error messages, with line numbers, of all errors in the program.

Example

A valid program:

use mlem_asm::*;
let valid_program = "
   noop
   move R:R0 R:SP;
   input R:R0;
   ; comment only

   ";
   let expected_program = Ok(vec![
           Instruction::NoOp,
           Instruction::Move(Address::RegAbs(Register::R0), Address::RegAbs(Register::SP)),
           Instruction::Input(Address::RegAbs(Register::R0))
   ]);
   let program = parse_program(valid_program);
   assert!(program == expected_program, "Program resulted in: {:?} not: {:?}", program, expected_program);

An invalid program:

use mlem_asm::*;
let invalid_program = "
   noop
   move R:R0 R:xx;
   output invalid;
   ; comment only

   ";
   let expected_errors = Err(vec![(2, "Unknown register name: xx".into()), (3, "Malformed address.".into())]);
   let errors = parse_program(invalid_program);
   assert!(errors == expected_errors, "Program resulted in: {:?} not: {:?}", errors, expected_errors);
