rustyline
A cross-platform readline implementation in Rust with Emacs/vi keybindings, history, and completion.
What is rustyline?
RustyLine is a readline library for Rust that provides line-editing features for interactive command-line applications. It is based on Antirez's Linenoise but extends it with Unicode support, advanced completion, and multi-platform compatibility. It solves the problem of building command-line interfaces with rich editing capabilities like history search, word completion, and multi-line input in a cross-platform Rust environment.
Rust developers building interactive command-line applications, such as REPLs, shells, or any terminal-based tool requiring user input with line-editing features. It is also suitable for developers needing a cross-platform readline alternative with support for both Emacs and vi keybindings.
Developers choose RustyLine for its robust feature set, including full Unicode support, flexible completion, history search, and a kill ring, all in pure Rust. Its unique selling point is cross-platform compatibility (Unix and Windows) combined with extensibility through traits like Validator for multi-line editing, offering a familiar readline experience without external dependencies.
