Lua Requires Chilkat v11.0.0+

Iterate over Matching Filenames

See more Zip Examples

Iterates over files within a .zip that match a pattern. In this case, the pattern is "*.pem". This example will open a .zip containing files of type .txt, .cer, .pem, and possibly others, and will iterate over only the .pem files. Lua

local chilkat = require("chilkat")

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

local zip = chilkat.Zip.new()

-- Open a .zip containing PEM files, among other things..
local success = zip:open_zip("qa_data/certs/thawte-roots.zip")
if not success then
    print(zip.last_error_text)
    return
end

local entry = chilkat.ZipEntry.new()
local pemStr = ""
local pattern = "*.pem"

local bHasMoreMatches = zip:entry_matching(pattern, entry)
while bHasMoreMatches do
    print("Entry: " .. entry.file_name)

    -- Get the uncommpressed contents of the entry:
    pemStr = entry:unzip_to_string(0, "utf-8")
    print(pemStr)

    bHasMoreMatches = entry:get_next_match(pattern)
end
