See more Zip Examples

Demonstrates how to create a .zip from in-memory byte data and strings, and to write the .zip to an in-memory image. Lua

local chilkat = require("chilkat")

-- This example requires the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

local crypt = chilkat.Crypt2.new()
local zip = chilkat.Zip.new()

local success = zip:new_zip("test.zip")
if not success then
    print(zip.last_error_text)
    return
end

-- Add the bytes 0x00 0x01 0x02 0x03 ... 0x0F as a file in the .zip
local bd = chilkat.BinData.new()
bd:append_encoded("000102030405060708090A0B0C0D0E0F", "hex")
zip:add_bd("binaryData.dat", bd)

-- Add the string "Hello World!" to the .zip
zip:add_string("helloWorld.txt", "Hello World!", "utf-8")
