Huffman

This is a little command line program using Huffman Coding to compress and decompress files

Usage

``` USAGE: huffman

FLAGS: -h, --help Prints help information -V, --version Prints version information

SUBCOMMANDS: decode Decode a file encode Encode a file help Prints this message or the help of the given subcommand(s) `` Huffman features 2 modes, encoding and decoding. The typical use case is first using theencode command to compress a file, and then thedecode` file to decompress it later.

Encoding

``` USAGE: huffman encode -o

FLAGS: -h, --help Prints help information -V, --version Prints version information

OPTIONS: -o The output file to put the decoded text into

ARGS: The input file to encode ``` This encodes a file by counting the occurrences of each byte in the file, and using that to construct a Huffman tree and assign a bit pattern to each byte. The output is a binary file, prefixed with the byte counts, and then followed by a stream of encoded bytes. Because we include the byte counts at the start of the file, we can rebuild the Huffman tree when decompressing the file.

Decoding

``` USAGE: huffman decode -o

FLAGS: -h, --help Prints help information -V, --version Prints version information

OPTIONS: -o The output file to put the decoded text into

ARGS: The input file to decode ``` This is the reverse of the encoding operation. This must be used on a file encoded with the same version of the program, otherwise unkown results will happen.
