archiver

A tiny archiver for text data compression using Shannon-Fano algorithm

Most valuable to large data. Supported formats:

• txt to txt
• txt to rtf
• rtf to txt
• rtf to rtf

Usage

There are two ways:

• Clone the repo and build the project using go build
• Download a released binary here

Archiving

1. ./archiver pack --method sf <filename> or shorted ./archiver pack -m sf <filename>
2. This will generate a new compressed file with .sf extension

Unarchiving

1. ./archiver unpack --method sf <filename> or shorted ./archiver unpack -m sf <filename>
2. Optional flag: --extension or -e used for decompressing target file to a specific extension
3. Available options: txt(default), rtf
4. This will generate a new decompressed file

Examples

Feel free to play around with files in the /examples dir

Efficiency

Depending on a data content compression efficiency could be up to 60%.
