Force optional arguments precede positional arguments

[smallkirby]

I have two arguments: one is a vector of strings, and the other is an optional value.

#[derive(Parser, Debug)]
struct Args {
    /// Text
    #[arg()]
    texts: Vec<String>,
    /// Do not print newline
    #[arg(short = 'n', default_value = "false")]
    newline: bool,
}

When executing ./test A B -n C, I expect newline to be false and texts to be vec!["A", "B", "-n", "C"]. However, it is parsed as vec!["A", "B", "C"], with newline set to true.

In short, I believe I need to ensure that optional arguments precede positional arguments. I would appreciate it if anyone knows of a solution.

Try setting allow_hyphen_values = true

It worked perfectly for me! Thanks a lot 🙏
