Hello, thank you for this package as it's improved my workflow a lot. I have forked the repository and made some changes (not sure if it's an improvement though)

I am not an expert in rust so I won't lie and I did use the help of chatgpt in some of the code changes. I am not expecting that my changes will go to your repository but I just want someone to check the implementation I made and of course accept feedback and suggestions for me to learn more.

Also, I haven't read some contributing guides in the code so forgive me if this method is not appropriate.

Thanks a lot!

Hi @iamriel,
thanks for your contribution!

I am happy to give this a thorough look, hopefully very soon. Could you meanwhile take a look at the CI run and fix the clippy diagnostics?

[iamriel]

@disrupted Absolutely, I forgot to install pre commit hooks, sorry about that. I have pushed an update in this commit. Thanks!

Really like this feature!
Any news when it could be merged?

This will pop current dir before check.

For example, I have config in my current dir /project/name/pyproject.toml

In this case first check will be on /project/pyproject.toml

This works ok

        loop {
            let potential_config_path = path.join(target_file_name);
            if potential_config_path.is_file() {
                return Config::from_file(potential_config_path)
                    .expect("Failed to load config file");
            }
            match path.pop() {
                true => (),
                false => return Config { tool: None },
            }
        }
