File compressor that uses the Huffman coding algorithm. It can be used both as a library and on the command line with the hzip and hunzip commands.

go get github.com/burakguven/hzip/...

Use hzip.NewWriter to get an io.Writer that will compress any data written to it.

Use hzip.NewReader to get an io.Reader that will do the opposite.

For example, the following program will write a hex dump of some compressed data to stdout.

package main

import (
	"encoding/hex"
	"fmt"
	"os"

	"github.com/burakguven/hzip"
)

func main() {
	w := hzip.NewWriter(hex.Dumper(os.Stdout))
	fmt.Fprint(w, "Hello World")
	w.Close()
	fmt.Println()
}

Any data piped into hzip will be compressed and written to stdout.

Any data piped into hunzip will do the opposite.

Example:

$ echo Hello World | hzip | hexdump -C
00000000  0c 00 00 00 09 00 00 00  0a 04 d0 20 03 00 48 04  |........... ..H.|
00000010  b0 57 04 a0 64 03 80 65  04 c0 6c 02 40 6f 03 e0  |.W..d..e..l.@o..|
00000020  72 03 20 bc 5e 2b 96 68                           |r. .^+.h|
00000028

$ echo Hello World | hzip | hunzip
Hello World
