autoclap

This lib builds on top of clap and auto-propagates Cargo.toml infos (name, version, author, repo) into the application using it.

Why?

Cargo.toml is the single source of truth containing application attributes such as:

• name
• version
• repository where it's hosted
• author(s)

This information is usually duplicated in the app's main, leading to potential inconsistencies (update in one place but not another).

Moreover, a crate unifying this would provide consistency across all apps using it.

Usage

fn main() {
    let app = autoclap(); // return a clap::App
    app.arg(
        Arg::with_name("myarg")
            .long("myarg")
            .short('m')
            .help("My arg description."),
    )
    .get_matches_safe()
    .unwrap_or_else(|e| e.exit());
}

Releases

The packge repository URL is concatenated with the version of a package to form a URL to a specific release.

This URL goes live when a release with the same version as the crate is published.

autoclap offers out-of-the box support for GitHub and GitLab.
