A toolkit for building your own interactive prompt in Rust.

Put the package in your Cargo.toml.

[dependencies]
promkit = { version = "0.14.0", features = ["runtime", "texteditor"] }

• Application-owned composition — Implement the Prompt lifecycle and combine only the widget states an application needs. Key bindings, focus, validation, background work, and other event policy remain in the application instead of framework-owned presets.
• Optional runtime and terminal lifecycle — Use the asynchronous prompt runtime when useful, and independently manage raw mode, the alternate screen, cursor visibility, and mouse capture with TerminalSession.
• Viewport-aware rendering — promkit-core handles wrapping or truncation, vertical pane allocation, cursor scrolling, clipping, resizing, and screen-to-widget hit testing.
• Reusable widget states — promkit-widgets provides text editing and display, list and checkbox selection, prefix search, spinners and status output, trees, JSON and YAML documents, and CSV tables.
• Efficient large-content projection — JSON, YAML, and table widgets can project only the visible terminal viewport instead of rebuilding all content on every redraw.
• Feature-gated modules — No Cargo features are enabled by default. Choose the runtime, terminal session, capabilities, and individual widgets needed by the application.
• Cross-platform terminal support — UNIX and Windows are supported through crossterm.

promkit provides a runtime and reusable widgets for building interactive terminal applications. The examples own their event policies and demonstrate how applications can compose the widgets they need.

Each section includes a command, source link, and recorded demo.

cargo run --bin readline
