mcfly
Intelligent shell history search that learns your patterns. Uses neural networks to prioritize suggestions based on directory, context, and command frequency.
Replace your default ctrl-r with a smarter shell history search that understands what you're working on. Instead of showing chronological results, McFly uses a small neural network to prioritize suggestions based on your current directory, recent commands, and execution patterns.
Key capabilities:
- Context-aware prioritization - Considers your working directory, command execution context, frequency, recency, and historical success rates
- Full-screen search interface - Rebinds
ctrl-rfor an intuitive reverse history search experience - Persistent tracking - Stores command metadata (exit status, timestamp, directory) in SQLite while maintaining your normal shell history
- Multi-shell support - Works with Bash (3+), Zsh, Fish, and PowerShell (7+)
- Wildcard matching - Use
%to match any number of characters during searches - History management - Scrub sensitive commands from both McFly database and shell history
- Built with Rust - Fast, safe, and reliable performance
The result is a dramatically faster workflow where the command you want appears at the top of suggestions, not buried in chronological noise. Perfect for developers who work across multiple projects and directories.
