Lua Requires Chilkat v11.0.0+

List Files/Directories in Zip by Index

See more Zip Examples

Demonstrates how to iterate over the files and directories in a zip archive by index. Lua

local chilkat = require("chilkat")

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

local zip = chilkat.Zip.new()

local success = zip:open_zip("qa_data/zips/sample.zip")
if not success then
    print(zip.last_error_text)
    return
end

local numEntries = zip.num_entries

local entry = chilkat.ZipEntry.new()

local i = 0
while i < numEntries do
    zip:entry_at(i, entry)
    -- Note: In the ZIP file format, it is not required for a ZIP file to contain explicit directory entries.
    -- However, explicit directory entries can be included for convenience and compatibility with certain ZIP file processing tools and software.
    -- An explicit directory entry in a ZIP file is an entry that specifically represents a directory, rather than a file.
    -- It usually has a directory name with a trailing slash (/) and zero-length content.
    if entry.is_directory then
        print(i .. ": " .. entry.file_name .. " (directory)")
    else
        print(i .. ": " .. entry.file_name)
    end

    i = i + 1
end

-- Sample output:

-- 0: aaa/ (directory)
-- 1: aaa/pigs.json
-- 2: bbb/ (directory)
-- 3: bbb/base64Cert.txt
-- 4: bbb/sub1/ (directory)
-- 5: bbb/sub1/brasil_cert.pem
-- 6: bbb/sub2/ (directory)
-- 7: bbb/sub2/penguins.gif
-- 8: bbb/sub2/starfish.jpg
-- 9: hamlet.xml
-- 10: hello.pdf
