minigrep

A basic command-line grep clone written in Rust. This is a learning project I built while working through The Rust Programming Language. It follows the minigrep tutorial with a some personal modifications.

Personal modifications

• Added case-insensitive search flag.
• Refactored search and search_case_insensitive to return an Iterator instead of a Vec.

Usage

cargo run -- query_string file_path

Case-insensitive search

Case-insensitive search can be enabled in two ways:

Option 1: Command-line argument

cargo run -- query_string file_path 1

Use 1 for case-insensitive and 0 for case-sensitive.

Option 2: Environment variable

IGNORE_CASE=1 cargo run -- query_string file_path

If both are provided, the command-line argument takes precedence over the environment variable.
