Tiny grep

The tiny-grep is a simple, yet powerful command-line utility written in Rust that filters and highlights specified patterns in text input from stdin.

Why

This is a tutorial project that can only read standard input.

Features

• Pattern Matching: Search for and highlight specified patterns within the text input from stdin.
• Color Highlighting: Uses the colored library to highlight matching patterns in red for easy identification.
• Multiple Pattern Support: Allows specifying multiple patterns as arguments for simultaneous search and highlight.
• Line Numbering: Outputs the line number alongside the original text, aiding in locating the highlighted patterns within the context.

Requirements

To use this utility, you need to have Rust installed on your system. This project also depends on the colored crate for text coloring functionality.

Install

git clone https://github.com/robotomize/tiny-grep.git
cd tinygrep

Usage

To use the grp, simply pass the patterns you want to highlight as arguments when running the program. You can specify multiple patterns separated by spaces:

cargo run -- pattern1 pattern2 pattern3
cargo build
cat main.rs|./tiny-grep stdin
