Demonstrates how to create a zip where the filename within the .zip is different than the filename that was added from the filesystem.

Download Chilkat Ruby Library

require 'chilkat'

zip = Chilkat::CkZip.new()

success = zip.UnlockComponent("anything for 30-day trial")
if (success != true)
    print "Failed to unlock zip component" + "\n"
    exit
end

#  Intialize the zip object by calling NewZip.
zip.NewZip("myZip.zip")

#  Add a reference to a file on disk to the zip object.
#  (When appending files to a zip, the files are not actually
#  read into memory.  References to the file(s) are added.
#  When WriteZip is called, the referenced files are streamed in
#  and compressed to the .zip.)
saveExtraPath = false
success = zip.AppendOneFileOrDir("c:/temp/a/hamlet.xml",saveExtraPath)
if (success != true)
    print zip.lastErrorText() + "\n"
    exit
end

#  The zip object references a single file.
#  Retrieve the entry object...

entry = zip.GetEntryByIndex(0)

#  Set the entry's filename to anything you want:
entry.put_FileName("somethingElse.xml")

#  Note: Internally, the zip component retains the name of
#  the file referenced.  The current setting of the zip entry's
#  FileName property is stored in the .zip when writing.

#  The zip written here will contain somethingElse.xml
success = zip.WriteZipAndClose()
if (success != true)
    print zip.lastErrorText() + "\n"
else
    print "Zip created!" + "\n"
