Add Binary Data to a ZIP Using AddBd

See more Zip Examples

This example demonstrates how to use the AddBd method to add binary data from a BinData object as a file entry within a ZIP archive.

The data is created entirely in memory, added to the ZIP as data/binary.dat, and then written to disk.

Lua

local chilkat = require("chilkat")

-- Create a new ZIP archive.
local zip = chilkat.Zip.new()

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

-- Create a BinData object containing binary content.
local bd = chilkat.BinData.new()

-- Append some bytes as hexadecimal.
-- The decoded bytes will become the contents of the ZIP entry.
success = bd:append_encoded("000102030405060708090A0B0C0D0E0F", "hex")
if not success then
    print(bd.last_error_text)
    return
end

-- Add the BinData contents as a file entry within the ZIP.
-- The file will be stored as "data/binary.dat" inside the ZIP archive.
success = zip:add_bd("data/binary.dat", bd)
if not success then
    print(zip.last_error_text)
    return
end

-- Write the ZIP archive to disk and close it.
success = zip:write_zip_and_close()
if not success then
    print(zip.last_error_text)
    return
end

print("ZIP archive created successfully.")
