ggrep

ggrep is a powerful, parallel grep implementation written in Go. It offers a fast and modular way to search for patterns in files and directories, leveraging Go's concurrency for high performance.

Features

• Parallel Search: Rapidly searches through multiple files using Go's goroutines.
• Modular Architecture: Portions of the logic are separated into a reusable ggrep package.
• Full Grep Support: Supports standard flags including ignore-case, invert-match, line-numbers, recursive search, and more.
• Colorized Output: High-visibility output for terminal users.

Installation

From Source

Ensure you have Go installed (version 1.23 or later).

git clone https://github.com/rewrite-everything-in-golang/ggrep.git
cd ggrep
go build -o ggrep main.go

Usage

ggrep [OPTIONS] PATTERN [FILE...]

Common Options

• -i, --ignore-case: Ignore case distinctions.
• -v, --invert-match: Select non-matching lines.
• -n, --line-number: Print line numbers of matches.
• -r, --recursive: Search directories recursively.
• -c, --count: Print only a count of matching lines.
• -l, --files-with-matches: Print only names of files with matches.
• -b, --byte-offset: Print byte offset of matches.
• --color: Enable colorized output.

Examples

Search for "func" in all Go files recursively with line numbers:

ggrep -rn "func" .

Case-insensitive search for a pattern in a specific file:

ggrep -i "pattern" main.go
