Compress a String and Save as a Gzip File

See more Gzip Examples

This example demonstrates how to use the CompressStringToFile method to compress a string and write the result directly to a Gzip (.gz) file.

The input string is first converted to its byte representation using the specified character set (in this case, UTF-8). The resulting bytes are then compressed using the Gzip format, and the compressed output is written directly to the specified file.

This method is convenient when you want to generate a compressed file from in-memory text without needing intermediate objects such as BinData or StringBuilder.

Lua

local chilkat = require("chilkat")

-- This example demonstrates how to compress a string and save the result
-- directly to a Gzip (.gz) file.

local gzip = chilkat.Gzip.new()

-- The string to be compressed:
local inputStr = "The quick brown fox jumps over the lazy dog."

-- Compress the string using UTF-8 and write to a file:
local success = gzip:compress_string_to_file(inputStr, "utf-8", "output.gz")
if not success then
    print(gzip.last_error_text)
    return
end

print("Compression successful.")
print("Gzip file written to output.gz")
