Compiler Macros

Compiler Macros are a helpful tool from the compiler, which allow you to get the compiler's help with operating on data.

List of Deen macros:

• print!(LITERAL_FORMAT, ...) void - Prints formatted input without a new line to standard output.

Example: print!("2 + 2{}", 2 + 2)

---

• println!(LITERAL_FORMAT, ...) void - Prints formatted input with a new line to standard output.

Example: println!("Hello, {}!", "World")

---

• format!(LITERAL_FORMAT, ...) *char - Returns a formatted string from provided input.

Example: format!("Number: {}", 5)

---

• panic!(LITERAL_FORMAT, ...) void - Calls the compiler's runtime panic with formatted input.

Example: panic!("Oops! Looks {}", "bad")

---

• sizeof!(EXPRESSION / BASIC_TYPE) usize - Returns the size (in bytes) of the provided expression or basic type.

Example: sizeof!(i32)

---

• cast!(EXPRESSION, TYPE) TYPE - Casts an expression to the targeted type.

Example: cast!(10, f64)
