rgrep v0.1.0

Overview

rgrep is a command-line tool that searches files for lines matching a given pattern, inspired by GNU grep and ripgrep. It leverages Rust's performance and safety guarantees to deliver fast, parallel searches across large codebases.

Key Highlights

Feature	Description
🚀 Parallel Search	Processes multiple files concurrently via Rayon
📝 Full Regex	Perl-compatible regular expressions via the regex crate
🎨 Colored Output	Matches highlighted in red bold, filenames in cyan, line numbers in yellow
📂 Recursive Traversal	Walk directory trees with automatic .gitignore / .ignore respect
🔎 Glob Filtering	Restrict searches to files matching patterns like *.rs or test*
⚡ Streaming I/O	Buffered reading (64 KB) for efficient processing of large files
