Gzip a File

See more Gzip Examples

Demonstrates how to create a .gz (gzipped file). Lua

local chilkat = require("chilkat")

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

local gzip = chilkat.Gzip.new()

-- This will create a .gz such that when ungzipped by a tool such as 7-Zip,
-- it will create "qa_data/hamlet.xml".
local success = gzip:compress_file("qa_data/hamlet.xml", "qa_output/hamlet.xml.gz")
if not success then
    print(gzip.last_error_text)
    return
end

-- Call CompressFile2 to explicitly specify the ungzip path
-- For example, this will create a .gz such that when ungzipped by a tool such as 7-Zip,
-- it will create "hamlet.xml".
local embeddedExtractPath = "hamlet.xml"
success = gzip:compress_file2("qa_data/hamlet.xml", embeddedExtractPath, "qa_output/hamlet2.xml.gz")
if not success then
    print(gzip.last_error_text)
    return
end

print("Success.")
