Ocen Huffman Compressor

This is a Huffman compression and decompression tool implemented in Ocen, a programming language created by Mustafa.

Overview

This program implements the Huffman coding algorithm for lossless data compression. It can both compress and decompress files using Huffman coding.

Features

• File compression using Huffman coding
• File decompression of Huffman-coded files
• Command-line interface for easy usage
• Supports input from files or standard input
• Can output to files or standard output

Usage

./huffman <-c|-d> -i <input_path> -o <output_path>

Options:

• -c or --compress: Compress the input file
• -d or --decompress: Decompress the input file
• -i <path> or --input <path>: Specify the input file path (default: /dev/stdin)
• -o <path> or --output <path>: Specify the output file path (default: /dev/stdout)
• -h or --help: Display help information

Examples

Compress a file:

./huffman -c -i input.txt -o compressed.bin

Decompress a file:

./huffman -d -i compressed.bin -o decompressed.txt

Implementation Details

The compressor uses the following key components:

1. A Node struct to represent elements in the Huffman tree
2. A priority queue (implemented as a min-heap) to build the Huffman tree
3. Bit-level I/O operations for efficient compression and decompression
4. Tree encoding and decoding for storing the Huffman tree structure

Building

To build the project, you need to have the Ocen compiler installed. Once you have it, you can compile the project using:

ocen compressor.oc -o huffman
