How do you prevent ziglings from running previously solved exercises?

@chrboesch start step is no longer available but there is still a reference in the README file.

Just run zig build -Dn=22 for a single exercise and increase the number after finishing. I'll have to take a look into why start doesn't work.

Is there still a way to prevent previously solved exercises from being compiled and checked other than specifying each exercise number manually?

zig version: 0.12.0-dev.152+411462e1c ziglings version: 1e9124b333310b982236d86e2928bbd44f93634e os: windows 11

Unfortunately it is not easy to implement, since the Zig build file is declarative.
In a local branch I have a draft implementation (using the build cache), but it has several problems.

For anyone that wants a more automated solution, you can use this nushell script. You can save it as runner.nu in the root of the ziglings directory, and then run it like so: nu runner.nu 5 10. This will run exercises 5 through 10.

# Change to the path of your dev zig executable
let zig_path = "~/Downloads/zig-dev/zig"

def main [start: int, end: int] {
    print $"Running ziglings exercises from ($start) to ($end)"
    let rng = $start..$end;
    for i in $rng {
        ^$zig_path build $"-Dn=($i)"
    }
}
