# LZW Compressing tool
|
|
|
|
This is a university assignment for which I aim to create an LZW algorithm implementation to create a small tool similar to `gzip` and `gunzip` that can compress and uncompress files in a lossless fashion.
|
|
|
|
This project is written is C++17, compiled with clang under a UNIX environment. Other compilers and environments will not be tested.
|
|
|
|
## How to use it
|
|
|
|
Currently, five different options are available to the user:
|
|
- `-h` or `--help` will show how to use `projet_lzw`
|
|
- `-c` or `--compress` tells `projet_lzw` to compress the input file
|
|
- `-u` or `--uncompress` tells `projet_lzw` to uncompress the input file
|
|
- `-i <file>` or `--input <file path>` specifies the input file to be compressed or uncompressed (**MANDATORY**)
|
|
- `-o <file>` or `--output <file path>` specifies the name of the output file. If not used, the default output name for compression is `output.lzw`, and the default name for uncompressing is `<filename>_uncompressed`.
|
|
|
|
By default, `projet_lzw` will uncompress the (mandatory) input file.
|
|
|
|
It is planned to add in the future a sixth option, `-p` or `--passes` that will allow to compress multiple times the input file.
