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

rust 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.
