Add Text from a StringBuilder to a ZIP Using AddSb

See more Zip Examples

This example demonstrates how to use the AddSb method to add text from a StringBuilder object as a file entry within a ZIP archive.

The text is converted to bytes using the specified character encoding before being stored in the ZIP archive.

This method is useful for dynamically generating text files entirely in memory without creating temporary files on disk.

Lua

local chilkat = require("chilkat")

local zip = chilkat.Zip.new()

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

-- Create a StringBuilder containing text data.
local sb = chilkat.StringBuilder.new()

sb:append_line("Line 1: Hello World!", true)
sb:append_line("Line 2: This text came from a StringBuilder.", true)

-- Add the StringBuilder contents as a UTF-8 text file
-- stored in the ZIP archive as "docs/readme.txt".
success = zip:add_sb("docs/readme.txt", sb, "utf-8")
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.")
