Flyline is a Bash plugin written in Rust that replaces readline to provide a modern command-line editing experience. It adds syntax highlighting, autosuggestions, fuzzy history search, rich prompts, mouse support, and AI agent-assisted command writing.

Use cases

• replace readline in bash with modern line editing
• add syntax highlighting and autosuggestions to bash
• fuzzy search my shell command history
• customize my bash prompt with widgets and animations
• get AI agent help writing shell commands
• improve bash tab completion with tooltips
• get an out-of-the-box polished shell without configuring many plugins

When to choose

• you use Bash as your primary shell and want modern editing features
• you want ble.sh-like functionality with better performance via Rust
• you want autosuggestions, fuzzy history, and rich prompts without assembling multiple plugins
• you want to extend your shell line editor in Rust

When to avoid

• you use zsh or fish rather than bash
• you rely on standard readline behavior or scripts that assume it
• you don't want mouse capturing in the terminal
• you need a battle-tested, long-established line editor
