Clientele.rs

Clientele makes it easy to write superb command-line utilities in Rust that follow consistent best practices on all target platforms including Linux, macOS, and Windows. It packages and re-exports clap, camino, dotenvy, wild, argfile, and getenv into a single easy dependency.

✨ Features

• Showcases how to structure a CLI program in Rust (see the examples).
• Loads environment variables from .env files (using the dotenvy crate).
• Provides convenience getters for common variables (using the getenv crate).
• Expands wildcard arguments (globs) on Windows (using the wild crate).
• Expands @argfiles similarly to javac or Python (using the argfile crate).
• Defines a standard set of essential CLI options (using the clap crate).
• Provides the Utf8Path and Utf8PathBuf types (using the camino crate).
• Recommends use of the sysexits.h(3) exit codes (see known-errors).
• Supports opting out of any feature using comprehensive feature flags.
• Adheres to the Rust API Guidelines in its naming conventions.
• 100% free and unencumbered public domain software.

🛠️ Prerequisites

• Rust 1.81+
