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
