Compiling and running cairo files

cargo run --bin cairo-run -- -p /path/to/file.cairo

If we want to run code that is gas tested: cargo run --bin cairo-run -- -p /path/to/file.cairo --available-gas 200

We currently only run the main function with no arguments beside implicits.

Examples

With gas:

``` fn main() -> Option:: { fib(1, 1, 13) }

/// Calculates fib... fn fib(a: felt, b: felt, n: felt) -> Option:: { get_gas()?; match n { 0 => Option::::Some(a), _ => fib(b, a + b, n - 1), } } ```

Without gas:

``` // Calculates fib... fn main() -> u128 { fib(1u128, 1u128, 100_u128) }

fn fib(a: u128, b: u128, n: u128) -> u128 { if n == 0 { a } else { fib(b, a + b, n - 1_u128) } } ```

Additional Information

• Functions with calls to get_gas will not compile without --available-gas value.
• Functions without calls to get_gas will not compile with --available-gas value.
• When running functions returning arrays --print-full-memory should probably be used, to actually see the values contained in the array.
