Include helper functions only if they are used.

ASM File for helper functions which will always be included

Add Various types and support for operators

• string: "hello"
• float: 3.35
• bool: true false

With support for casting.

Python-like operator chaining.
Example:
1 < 2 < 3 which is equivalent to 1 < 2 and 2 < 3

Add warnings and print them to the screen.

• Unnecessary Casts

Change program definition:
A list of statements (instead of an expression).

multiple assignments in one operation.
Examples:

int a = 1, b = 2;
a, b = 3, 4;

int a, b, c, d;
a, c, b, d = 1, 2, 3, 4;

int a = 1, b = 2;
a, b = b, a;

• Add methods:
  • Next
  • Peek

• Research Parser
• Plan and add issues
• Start coding

Including memory management (for variables which are saved on the stack).

Operators to implement:
negation: -x
bitwise not: ~x
factorial: x!

Get input from places other than the console.

• Console program input.
• Console program multiline input.
• File input
• Command line arguments.
  • Default main menu
  • Help command
  • File input
  • Console input

support for boolean operators

• Relational: <, >, <=, >=, ==, !=
• Logical: &&, ||, !

• declaration with assignment: int a = 3;
• multiple declarations: int a = 1, b = 2;

Use example:

{
    int a = 4;
    print a ** 2 + 4;
}

To reproduce:
Compile:

12345678901234567890 + 5

List of operators:

• bitwise operators: And &, Or |, Xor ^.
• Other operators: Exponentiation **, Modulo: %,

• add argument parser
• improve current options
• improve menu
  • add quit option
• prepare for future additions:
  • add -o or --output option for specifying output file
  • detailed compilation file -D or --detailed
  • multiple files for --file option

• Add Exception calsses

Stop evaluating logical expressions with known results. For example:

• 0 && x
• 1 || x

Inlcuding all types.
+=, -=, /=, *=...

• Edge cases (empty statements, empty blocks...)
• different types
• wierd syntax (example: int 5 = 3;...)

• Remove Line number from node's constructor
• Primitive constructor from string with TryParse

bool ? ret1 : ret2

Example: 1 + a * 2

To reproduce:
Compile file:

1 + 1
2 - 2
