CLI Tools

The mental model behind idiomatic Rust CLIs - declarative argument parsing with clap, exit codes as a contract with the shell, and ownership concerns in terminal I/O.

Learn the fundamentals of building Rust CLIs with 10 practical examples, covering basic entry points, argument parsing, and exit codes.

Learn to parse command-line arguments, subcommands, and flags in Rust using the clap crate, with examples for help generation and validation.

Layer CLI flags, environment variables, and config files with a clear precedence order. Learn to implement this with a Rust example.

Format human-facing CLI output with progress bars, spinners, and color. Learn to use indicatif and owo-colors for rich terminal feedback.

Learn to build interactive terminal user interfaces (TUIs) with ratatui, a Rust library. Create dashboards, log viewers, and wizards.

Learn to implement user-friendly CLI error reporting using anyhow for context and miette for rich diagnostics and formatted reports.

Generate shell completions and man pages directly from your clap definitions. Learn to implement this for Bash, Zsh, Fish, PowerShell, and Elvish.

Learn to package and distribute Rust CLI binaries using cargo-dist, GitHub Releases, and package managers for reproducible, cross-platform artifacts.

Learn best practices for Rust CLIs covering interface design, scriptability, configuration, and user experience for discoverable, fast tools.
