autoclap

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

Running app --help now automatically includes this information in its output.

Why?

Cargo.toml is the single source of truth containing application attributes such as: * name * version * author(s) * description

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.

Finally, code for app initialization is minimal.

Usage

```rust use clap::{App, Arg}; use autoclap::autoclap;

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

Now, running app --help now produces:

app 0.1.0 :: https://github.com/username/app/releases/tag/0.1.0 Crate Author <crateauthor@e.mail> 🧵 The crate awesome description.

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.
