WinGrep 🚀

Right now it's still in progress and the only feature is for a plain text, but im working to add more features

A blazing fast, multi-threaded, recursive command-line search tool built in Rust.

Designed as a modern, cross-platform alternative to grep for Windows (and Linux/macOS), optimized for speed using memory mapping and parallel processing.

✨ Features

• ⚡ Zero-Copy Optimization: Uses memory-mapping (mmap) to search files directly on disk without heavy RAM allocation.
• 🧵 Parallel Search: Uses rayon to utilize all CPU cores when searching multiple files.
• 📂 Recursive Search: Deep search functionality with the -r flag.
• 🎨 Colored Output: Highlights matches and line numbers for better readability.
• 🪟 Cross-Platform: Compiles to a single static binary (.exe on Windows).

📦 Installation

From Source

You need to have Rust installed.

git clone [https://github.com/SoimanVasile/wingrep.git](https://github.com/SoimanVasile/wingrep.git)
cd wingrep
cargo build --release

The executable will be located in target/release/wingrep (or wingrep.exe on Windows).

🛠 Usage

Right now is not available about the directory and path, but im working on this

# Basic search in a single file
wingrep "search_term" filename.txt

# Recursive search in a directory
wingrep -r "TODO" ./src

# Search with a specific path
wingrep "function" /path/to/project

📊 Benchmarking

To stress-test WinGrep against standard grep, we use a separate tool to generate massive datasets.

1. Get the Generator: Clone the Haystack Generator repository.

   git clone [https://github.com/SoimanVasile/haystack-generator.git](https://github.com/SoimanVasile/haystack-generator.git)

2. Generate Data: Create a 70MB+ test file with hidden needles.

   cd haystack-generator
   python3 generate_data.py

3. Run the Benchmark: Compare WinGrep against standard grep.

   # Linux / Git Bash
   time ../target/release/wingrep "NEEDLE" huge_test_file.txt > /dev/null
   
   # Windows PowerShell
   Measure-Command { .\wingrep.exe "NEEDLE" huge_test_file.txt | Out-Null }
