go-lz-string

Go implementation of lz-string

This is an implementation of lz-string written in Go. You can also embed go-lz-string as a library to your Go products.

lz-string algorithm version

Currently it implements algorithm that is compatible with lz-string@^1.4.4

Usage as a CLI

Installation

From GitHub Releases

See GitHub Releases.
Available binaries are:

• macOS
• Linux
• Windows

go install

Go v1.18 or later is required.

go install github.com/daku10/go-lz-string/cmd/go-lz-string@latest

Example

$ go-lz-string compress <filename> -o <output-filename>
# use standard input/output
$ echo -n '🍎🍇🍌' | go-lz-string compress -m base64
jwbjl96cX3kGX2g=
$ echo -n 'jwbjl96cX3kGX2g=' | go-lz-string decompress -m base64
🍎🍇🍌

Compression and decompression methods are not only base64 but also invalid utf-16, utf-16, encodedURIComponent and byte array are implemented as well as original javascript program. To use other methods, see go-lz-string help

Usage as a library

Installation

go get -u github.com/daku10/go-lz-string

Example

package main

import (
	"fmt"

	lzstring "github.com/daku10/go-lz-string"
)

func main() {
	var input string = "Hello, world"
	var compressed []uint16 = lzstring.Compress(input)
	// [1157 12342 24822 832 1038 59649 14720 9792]
	fmt.Println(compressed)
	var decompressed string = lzstring.Decompress(compressed)
	// Hello, world!
	fmt.Println(decompressed)
}

Motivation

• Need CLI tool to use easily
• Some the go implementations of lz-string already exists, but there are lack of some functionality.
  • pieroxy/lz-string-go support decompression encodedURIComponent only.
  • lazarus/lz-string-go support compression/decompresson, but base64 method only, and specific input like emoji can not be compressed correctly.
