so good!

[enitrat]

great, smart approach! LGTM, didn't test but if it works lets go :)

There seems to be a problem, there is no Output whatsoever

use debug::PrintTrait;
'Hello, World!'.print();

does nothing, output is:

Output:
====================

====================

Seems like instead of running programs with scarb, you only compile and the output is always empty

pub fn scarb_build(file_path: &PathBuf) -> anyhow::Result<String> {
    let crate_path = prepare_crate_for_exercise(file_path);
    let config = scarb_config(crate_path);

    match compile(&config, false) {
        // Here it returns an empty string and that's why there is no output
        Ok(_) => Ok("".into()),
        Err(_) => anyhow::bail!("Couldn't build the exercise..."),
    }
}

This starts at:

starklings-cairo1/src/verify.rs

Line 62 in c8d77d4

fn compile_and_run_cairo(exercise: &Exercise) -> Result<String, ()> {

this function only compiles, doesn't run the program
and this is where the empty string comes from:

starklings-cairo1/src/scarb.rs

Line 37 in c8d77d4

Ok(_) => Ok("".into()),

Hi @beeinger - thanks for investigating, shramee is on it!

#171 should solve it

[shramee]

The prints should be above it, output is the output of run function (main()). If your function returns something, it'll be shown here. Runner just prints the messages.

Sorry, this is after #171. You can try that branch.

Oh, makes sense!
Already tried that branch, thx, also have a look at this: #171 (comment)
