How to show alias of an argument when a help message is specified?

[nicole-jf]

When an alias is set it usually it is displayed in the help message:

#[derive(Parser)]
#[command(
    name = "foo",
    version,
    long_about = None
)]
pub(crate) struct Cli {
    #[command(subcommand)]
    pub(crate) command: Option<Commands>,
}
#[derive(Subcommand)]
pub(crate) enum Commands {
    #[command(visible_alias = "a")]
    Add {
       [...]
    },
}

Usage: foo [COMMAND]

Commands:
  add      [aliases: a]

Options:
  -h, --help
          Print help (see a summary with '-h')

  -V, --version
          Print version

but when a help message is also set:

#[derive(Parser)]
#[command(
    name = "foo",
    version,
    long_about = None
)]
pub(crate) struct Cli {
    #[command(subcommand)]
    pub(crate) command: Option<Commands>,
}
#[derive(Subcommand)]
pub(crate) enum Commands {
    /// Adds something
    #[command(visible_alias = "a")]
    Add {
       [...]
    },
}

the alias is nowhere to be seen:

Usage: foo [COMMAND]

Commands:
  add       Adds something

Options:
  -h, --help
          Print help (see a summary with '-h')

  -V, --version
          Print version

Is there a way to show the alias alongside the help message?

For some reason, I'm not able to reproduce this.

I used the following code (nargo is an alias for cargo +nightly -Zscript)

#!/usr/bin/env nargo
---
[dependencies]
clap = { version = "4", features = ["derive"] }
---

use clap::Parser;
use clap::Subcommand;

#[derive(Parser)]
#[command(
    name = "foo",
    version,
    long_about = None
)]
pub(crate) struct Cli {
    #[command(subcommand)]
    pub(crate) command: Option<Commands>,
}
#[derive(Subcommand)]
pub(crate) enum Commands {
    /// Adds something
    #[command(visible_alias = "a")]
    Add {},
}

fn main() {
    Cli::parse();
}

$ ./clap-6277.rs --help
