Ion Documentation

Welcome to the official documentation for Ion — the Cargo for C++.

Ion is a fast, robust, and modern package manager, build tool, and linter for C++ — written entirely in Rust. It brings the intuitive workflow of Rust's cargo and JavaScript's npm to the C++ ecosystem.

Core Features

• Single Manifest: Declare your dependencies in a simple ion.toml.
• Multi-Registry: Fetch from the native Ion registry, ConanCenter, vcpkg, GitHub, or Git URLs.
• Reproducible Builds: Every dependency tree is locked into ion.lock.
• Built-in Linter: Catch bugs automatically with ion check and ion lsp.
