Overview

CLI development
without the repetition.

Cliva is a collection of focused Rust libraries designed to make CLI development faster, cleaner, and less repetitive.

Rather than putting everything into one large library, Cliva is organized as a Cargo workspace containing independently usable crates.

Use only what your application needs. Nothing more.

Components

Focused libraries. One workspace.

Each component solves a specific part of CLI development and can be used independently.

Architecture

Independent pieces. One ecosystem.

Cliva keeps CLI development and terminal interaction separate, so each part can be used independently or together.
