speedgrep

A no‑nonsense, literal‑string grep clone built in Rust, specialised for literal substring search of a file

⬇️ Download

cargo install speedgrep

📝 To-Do

• Increase speed and efficiency
• Add nicer colours without sacrificing performance
• Make a cleaner output

✨ Features

• 🧠 Simple syntax — just speedgrep <file> <string>
• ⚡ Ridiculously fast
• 🔢 Shows line numbers
• 📦 Tiny binary

🧪 The Trick?

Why is it 20x faster? Because it avoids the "Regex Tax" and respects the hardware:

• 🚫 NO REGEX: Pure literal substring matching.
• 📦 Syscall Batching: Buffers 64 matches into a single to minimize the ammount of syscalls
• ♻️ Buffer Reuse: Reuses a single string
• ⚡ Single Process: Utilizes a single process to minimize overhead

🚀 We Beat Ripgrep

On a 1,000,000‑line test file:

• ⚡ speedgrep: 361ms
• 🦀 ripgrep: 7.4 seconds

Note: Speedgrep is a speed demon, while ripgrep is a regex engine.

Minimalism wins.
