Getting all unparsed arguments

[mikevoronov]

Hi!

I am wondering, is it possible to partially parse only begginng of a cmd line to get remaining arguments as a Vec<&str>. In my case I am dealing with the wrapper for cargo and want to do smth like that:

    match app.get_matches().subcommand() {
        ("build", Some(arg)) => {
            let remaining_args: Vec<&str> = arg.get_remainings();

            crate::build::build(remaining_args)
        }

Let's say I run this app with app build --release --manifest_path path, so remaining_args should be equal to vec!["--release", "-manifest_path", "path"]. Is it possible to achieve on the current version of clap?

Apply it to the subcommand

Thank you for the answer, I've tried it and AllowExternalSubcommands but it didn't work for me. Could you please take a look at my project?

Here I am traying to obtain all trailing args https://github.com/fluencelabs/fce/blob/cli/tools/cli/src/main.rs#L44 and here set the appropriate setting for the subcommand: https://github.com/fluencelabs/fce/blob/cli/tools/cli/src/args.rs#L28.

Then with
fce build I got panic on unwrapping
fce build --release I got error: Found argument '--release' which wasn't expected, or isn't valid in this context.

Thank you in advance.

I don't think AllowExternalSubcommands is what you're looking for. I was advising AppSettings::TrailingVarArg plus a multiple positional argument, the link above has an example. That should do exactly what you want.

Thank you for the help, done it.
