How to include sha1 from git in the version report using derivce interface of clap?

[szabgab]

Having

#[command(version)]

in the struct definition allows the user to pass the --version flag showing the version number from Cargo.toml. Is there a way to include the current sha1 from git? e.g. like this:

$ cargo --version
cargo 1.75.0 (1d8b05cdd 2023-11-20)

Libraries like https://crates.io/crates/shadow-rs or https://crates.io/crates/vergen can be used to get the information you need. If you generate the string at runtime, you'll need to run cargo add clap -F string
