Data compression cli program

par - pocket archiver. A simple data compression cli program, which supports a set of compression algorithms:

• Huffman coding
• Yet to be added

Installation

Clone the repository

git clone https://github.com/sekvanto/par
cd par

Compile

make

Run

./archive [arguments]

To clean the source directory, run

make clean

Example

Usage

Synopsis

./archive [options] [input file] [output file]

Options

Optional flags:

-h, --help Show help

-a Explicit flag to forcefully archive first file into second file

-u Explicit flag to unarchive

--algorithm=algorithm-name

If zero filenames are specified, program archives the default file ("test.txt").

If only one filename is specified, the output file name is generated automatically, e.g. Input = "file.txt" => Output = "file.txt.par". If input name has ".par" extension, file will be decompressed and gain extension ".uar", e.g. Input = "file.txt.par" => Output = "file.txt.uar".

If two filenames are specified, first file is compressed/decompressed into second file. Function will depend either on flags, or on input filename.

algorithm-name

• huffman (*)
• adaptive-huffman

TODO

☑ Add Huffman coding support
☑ Modify program structure, rewrite it from Java to C
▢ Add a few other lossless algorithms
▢ Add support for multithreading
▢ Add a few lossy data compression algorithms (esp for multimedia)
