@asir66 Thanks for your effort!
I've checked the implementation in `cargo-sgx`:
```
#[derive(Debug, Parser)]
#[clap(bin_name = "cargo")]
#[clap(version = VERSION)]
pub(crate) enum Opts {
/// Utilities to build sgx program.
#[clap(name = "sgx")]
#[clap(version = VERSION)]
#[clap(action = ArgAction::DeriveDisplayOrder)]
Sgx(SgxArgs),
}
#[derive(Debug, clap::Args)]
pub(crate) struct SgxArgs {
#[clap(subcommand)]
cmd: Command,
}
#[derive(Debug, clap::Subcommand)]
enum Command {
#[clap(name = "build")]
Build(BuildCommand),
#[clap(name = "run")]
Run(RunCommand),
...
}
```
It seems `cargo-sgx` only supports being invoked as cargo-sgx sgx xxx and
doesn't support the two scenarios.
Could you help with a brief study of how other cargo subcommands handle this
case?
To achieve the goal of "cargo-optee acting as a cargo subcommand," it's good
to follow the established principles used by other subcommands. If there is a
standard convention, we can implement it in the same way; otherwise, the
current implementation is fine.
