Description

This is a simple archivator that can compress and decompress files.

Features

• Compression method:
  • Variable Length Coding (VLC) algorithm.
  • Shannon-Fano algorithm.

Usage

Install

1. Clone the repository
2. Build the project

go build

Compress file

./archivator pack -a <algorithm> <file>

Decompress file

./archivator unpack -a <algorithm> <file>

Example

Compress file using Shannon-Fano algorithm

./archivator pack -a vlc Pride\ and\ Prejudice.txt

Decompress file using Shannon-Fano algorithm

./archivator unpack -a vlc Pride\ and\ Prejudice.vlc

Screenshots

As you can see the size of the file has decreased

Book file compressed and correctly decompressed back. Decoded file is the same as the original file.
