Download Chilkat Ruby Library

require 'chilkat'

zip = Chilkat::CkZip.new()

#  Any string unlocks the component for the 1st 30-days.
success = zip.UnlockComponent("Anything for 30-day trial")
if (success != true)
    print zip.lastErrorText() + "\n"
    exit
end

#  Downloads a .zip into memory and opens it.
success = zip.OpenFromWeb("http://www.chilkatsoft.com/testData/hamlet.zip")
if (success != true)
    print zip.lastErrorText() + "\n"
    exit
end

#  It can be unzipped to disk:

fileCount = zip.Unzip("c:/temp")
if (fileCount < 0)
    print zip.lastErrorText() + "\n"
    exit
end

#  Alternatively, individual entries may be unzipped into memory.
#  In this case, it is unzipped into a string:

addCR = true
entry = zip.GetEntryByName("hamlet.xml")
if (!(entry == nil ))
    #  If the file has bare LF line endings, add the CR to get
    #  CRLF line endings.
    fileContents = entry.inflateToString(addCR)
    print fileContents + "\n";
end
