(Ruby) Create Zip in a BinData Object

Recursively appends files in a directory tree and writes a zip archive into a Chilkat BinData object.

require 'chilkat'

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

zip = Chilkat::CkZip.new()

# Initialize the zip object.  Because we will never actually write a zip file to the filesystem,
# the filepath passed to NewZip does not matter.
success = zip.NewZip("x.zip")
if (success != true)
    print zip.lastErrorText() + "\n";
    exit
end

# Append a directory tree.  The call to AppendFiles does
# not read the file contents or append them to the zip
# object in memory.  It simply appends references
# to the files so that when WriteBd, WriteZip, or WriteZipAndClose 
# is called, the referenced files are streamed and compressed
# into the .zip output file (or BinData object).

recurse = true
success = zip.AppendFiles("c:/temp/a/*",recurse)
if (success != true)
    print zip.lastErrorText() + "\n";
    exit
end

# Write the zip archive into the bdZip object.
bdZip = Chilkat::CkBinData.new()
success = zip.WriteBd(bdZip)
if (success != true)
    print zip.lastErrorText() + "\n";
    exit
end

# We could directly access the bytes of the zip archive, or perhaps
# get the zip bytes in base64 format.
zipAsBase64 = bdZip.getEncoded("base64")
print zipAsBase64 + "\n";

# Or the zip can be used by some other Chilkat method call that accepts
# a BinData object as an argument.
