Flyline: A Bash plugin to replace readline for a modern line editing experience

Flyline is a Rust-based readline replacement for Bash that packs in features most developers have had to cobble together from multiple plugins: fuzzy history search, AI-assisted command writing, syntax highlighting, mouse support, rich animated prompts, and improved tab completion. It loads directly into Bash as a custom builtin, requires no plugin manager, and is configurable via tab-completion-driven CLI commands.
