GleamLZ_String

This is a Gleam implementation of the lz-string compression algorithm

Installation

gleam add gleamlz_string

Usage

import gleamlz_string
 
pub fn main() {
  let string = "Hello World!"

  //Uint8Array
  gleamlz_string.compress_to_uint8(string)
  //<<4, 133, 48, 54, 96, 246, 0, 64, 234, 144, 39, 48, 4, 192, 132, 64>>
  gleamlz_string.decompress_from_uint8(<<4, 133, 48, 54, 96, 246, 0, 64, 234, 144, 39, 48, 4, 192, 132, 64>>)
  //Ok("Hello World!)
	
  //Base64
  gleamlz_string.compress_to_base64(string)
  //"BIUwNmD2AEDqkCcwBMCEQA=="
  gleamlz_string.decompress_from_base64("BIUwNmD2AEDqkCcwBMCEQA==")
  //Ok("Hello World")
	
  //URI encoded
  gleamlz_string.compress_to_encoded_uri(string)
  //"BIUwNmD2AEDqkCcwBMCEQA$$"
  gleamlz_string.decompress_from_encoded_uri("BIUwNmD2AEDqkCcwBMCEQA$$")
  //Ok("Hello World!")
    
}

Testing

Run generate_testcases.sh first which will generate a bunch of test data using the base JavaScript lib to compare with. Once that's done run gleam test
