Disable options after a certain positional argument

[david0u0]

Something like the bash command: it has some options e.g. "-e", and some positional argument, file and more_args. I want everything after file to be supplied to more_args, even if it looks liks an option .

I'm thinking of something like trailing_var_arg + allow_hyphan_values:

#[derive(Parser)]
struct Bash {
    #[clap(short)]
    pub e: bool
    pub file: String,
    #[calp(allow_hyphen_values = true, trailing_var_args = true]
    pub more_args: Vec<String>
}

The above code works in some cases. If user type "bash a.sh x -e", more_args becomes ["x", "-e"].

However, if "-e" is the first value, like "bash a.sh -e x", it will be provided to the option instead of positional args. Which makes sense because the more_args doesn't even begin. Users have to type "bash a.sh -- -e x" instead.

I can't find anywhere in the document how to achieve my goal. I think it's not possible, according to #5413.

Some workaround would be making file and more_args a single Vec positioal argument. However there's some drawback e.g. suboptimal help message, unable to provide different parsing rule, etc.

So I'm thinking of a new property, something like disable_options_onward, to add to argument file, so that clap knows it should parse everything as positional arguments onward.

I'm not sure if this aligns with clap's philosophy. I'd love to provide a PR if you see fit. Thanks!

Yes, the existing -e takes precedence over the capturing.

And yes, combining the arguments is the current workaround.
