(Ruby) Iterate over Matching Filenames

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.

Note: This example requires Chilkat v11.0.0 or greater.

require 'chilkat'

success = false

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

zip = Chilkat::CkZip.new()

# Open a .zip containing PEM files, among other things..
success = zip.OpenZip("qa_data/certs/thawte-roots.zip")
if (success == false)
    print zip.lastErrorText() + "\n";
    exit
end

entry = Chilkat::CkZipEntry.new()

pattern = "*.pem"

bHasMoreMatches = zip.EntryMatching(pattern,entry)
while bHasMoreMatches == true

    print "Entry: " + entry.fileName() + "\n";

    # Get the uncommpressed contents of the entry:
    pemStr = entry.unzipToString(0,"utf-8")
    print pemStr + "\n";

    bHasMoreMatches = entry.GetNextMatch(pattern)
