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.
Allowed Types Casts
integer type -> integer typeinteger type -> float typeinteger type -> charinteger type -> boolinteger type -> pointer type
float type -> float typefloat type -> integer type
char -> integer typebool -> integer typepointer type -> integer typepointer type -> pointer type
Example: cast!(10, f64)
