GrepMadeBetter is a simple tool for phrase searching among files.

GMB is a grep like CLI (command line interface) program, that searches for user-defined phrases in files. It supports text, markdown and python/c++ files as well as special formating of output. Additional information:

• compatible with Linux OS
• Polish language supported

The project follows a modular CLI architecture with clear separation of concerns.

The program is structured as a simple processing pipeline:

CLI input → ArgumentParser → Config → FileReader → SearchEngine → OutputFormatter → stdout

Responsible for parsing command-line arguments (argv) and building a Config object.

A lightweight data structure that stores all user-provided options, such as:

• search pattern
• file path
• flags (e.g. ignore case)

Reads input files and returns their content as a list of lines.

Implements the core search logic.

Formats and prints results in a grep-like output style.

• Single Responsibility Principle (each module has one responsibility)
• Separation of concerns (I/O, parsing, and search logic are separated)
• Stateless processing (data flows through the pipeline without global state)
• Dependency Injection (components receive data rather than creating dependencies internally)
